Ra-223 dichloride is a first-in-class alpha-emitting radiopharmaceutical recently introduced into clinical practice for treatment of men with Castration-Resistant Prostate Cancer (CRPC) and symptomatic bone metastases. Due to the proven benefit on Overall Survival and the favorable toxicity profile, Ra-223 therapy is gaining widespread use in both US and Europe. In this article, we describe the routinary management of patients undergoing Ra-223 treatment in our Institution. Currently, Ra-223 therapy is indicated for 6 intravenous injections (55 kBq per kg of body weight) administered every 28 days. In comparison to other radiopharmaceuticals, Ra-223 handling and administration do not need any additional training for authorized users. Due to the minimal external dose rate emission, Ra-223 dichloride can be delivered in an outpatient setting. Moreover, no particular precautions other than standard hygiene measures must be taken by patients’ family members or caregivers. Ra-223 therapy is associated to a favorable hematologic toxicity profile, while non-hematologic adverse events are generally mild and easy to manage. Given the favorable toxicity profile of this treatment, clinical trials are currently ongoing to evaluate efficacy and safety of Ra-223 treatment in combination or sequence with recently approved drugs such as abiraterone acetate, enzalutamide and sipuleucel-T. In addition, the recent interest in Ra-223 bone lesion dosimetry could open the way to a dosimetric-based therapeutic approach with Ra-223. In this new scenario, results of these promising clinical trials may help clarifying the optimal sequencing of new therapeutic possibilities for metastatic CRPC and the appropriate eligibility criteria for Ra-223 treatment in oncologic patients.

The well recognized white adipose tissue is an endocrinal organ secreting various hormones and this article simply indicates to the physiologic concepts brown fat tissues (BAT) which are extremely active endocrine organs and play various metabolic active roles in intermediate metabolism. The physiologic function of Brown adipose tissues contributes to energy-producing parts of the cell. Its amount is rare up to approximately one hundred and thirty gram and implies important characteristics for mammals. An increase in energy expenditure could be an aim by activation of BAT, seems futurity to reduce body weight that needs a vast majority of fundamental research to facilitate its occurrence [1]. Brown fat tissue generates heat and has valuable importance for human metabolism [2,3]. Brown fat tissue is decreased in overweight and obese people and possibly activating brown fat tissue might help for reducing weight and weight-related metabolic disorders like insulin resistance.

Background: The use of a custom-made orthotic plantar device is referenced as a true sensor-motor facilitation tool for the control of the postural orthostatic and orthodynamic position in patients with Parkinson’s disease. Aim: To outline the postural and kinematic effect of a pro-ergonomic multilayer foot insole versus a custom-made carbon-kevlar dynamic foot insole in a cohort of patients affected by extrapyramidal disease. Setting: A rehabilitation institute for the treatment of neurological and orthopaedic gait disorders. Methods: A sample of 8 patients (mean age of 82.6), of whom 4 affected by Parkinson’s disease (P) and 4 by Parkinsonism (PS) were recruited for the aim of this study. In line with our inclusion criteria (clinical-functional diagnosis of Parkinson’s disease or Parkinsonism, Webster scale ≤ 20, Mini-mental State Examination (MMSE) ≥ 18), the study design developed in 2 times: a. time T1 (or evaluation time), in which recruited patients affected by Parkinson’s disease or Parkinsonism were evaluated at the Hospital and Noble Resting House Paolo Richiedei through an accurate functional (Conley scale, Barthel Index scale, Tinetti scale and the Berg Balance Scale), postural evaluation (VPA) and walking examination (VGA, baropodometric evaluation, kinematic gait evaluation through WIVA system); to each group of patients of our study were therefore entrusted 4 foot-insoles, of which 2 synthetic and 2 carbon-kevlar custom-made foot-insoles called PRODYNAMIC; at the end of this step, patients started with our integrated rehabilitative treatment course. b. time T2 (or experimental time; 90 days from T1), a new clinical-instrumental evaluation of each patient was performed, repeating the clinical-functional and instrumental evaluation performed at the time T1 in a specular way; this assessment was performed in FW condition, with personal footwear and previously acquired foot-insoles used during the evaluation at the T1 time. Results: Most of our patients have been able to find benefit from the use of the plantar orthosis and integrated rehabilitation treatment so as to bring some modifications within personal postural attitude, recording an improvement but not uniform change within the sample. The results obtained by comparing the VPA at time T1 and at time T2 explain how patients affected by both clinical forms tend to establish incorrect postural attitudes due to stiffness and appearance of hypertonic plasticity, which become then structured and only partially modifiable. There was a general performance improvement in line with the VGA: within the P.B group, we observed with the use of the Prodynamic insole a partial or even complete normalization of the dynamic heel-contact phase, a better alignment of the COP in its excursion from the 1st to the 2nd rocker phase of the step, a notable facilitation to the inertial thrust in progress in the 3rd and 4th rocker phase, an improvement in the eccentric control of the patellofemoral alignment in the acceptance phase of the so-called load-response in stance and, finally, the acquisition of a more physiological propulsion structure of the trunk basin unit with an improvement of the clearance and fixation skills in the sequential phases of the step. This trend was evident but not uniform in the other groups considered. Analysis of the evolution of the degree of functionality in the daily life activities expressed by the Barthel index, passing from time T1 to the time T2, showed an improvement and consistent change in all groups considered within our study that we can find in a more or less way for the other clinical outcome data. An objective time-related and intra-group comparison of the raw static and dynamic baropodometric data acquired in our 4 study conditions showed different time-related trends for the two groups taken into consideration. A specific WIVA profile was found for each pathology group, highlighting different trends passing from time T1 to time T2 in particular of the gait cadence and gait speed. In particular, in the “Prodynamic” study condition the gait cadence shows in the Parkinson group a significant increase from time T1 to time T2, passing respectively from an average value of 41.9 ± 11.7 to 54.9 ± 1.1; patients of the Parkinsonism group showed a value of the average gait cadence at time T1 higher than the other study conditions at the same evaluation time, with an increase of this data from T1 to T2, passing from 43.1 ± 11.8 to 47.4 ± 4.4. If we consider the gait speed time-related trend, in the “Prodynamic” study condition at T1 the gait speed in Parkinson patients is similar to that recorded in the “shoe” study condition; in Parkinsonism the gait speed recorded at time T1 is higher than that recorded in the other study conditions; at time T2 there is a less evident increase in speed compared to that observed in patients with Parkinson’s. Conclusion: In today’s management of the profile of complexity of extrapyramidal pathology, the association of several health figures is of fundamental importance, with professional profiles and diversified skills, in such a way as to be able to guarantee a comprehensive management of the patient. From this point of view, the figure of the orthopedic technician will be able to play a new role within the rehabilitation team, which will be responsible for the best possible functional response (deriving from an optimal integration between orthotic and rehabilitation treatment) of patients with Parkinson’s disease.

Understanding the obesity-related genes may provide future therapeutic strategies to modulate disease progression. UCP2 separates oxidative phosphorylation (OXPHOS) from ATP production in the inner mitochondria. Figure 1 shows the differences among UCP1, 2, 3. The main role of UCP2 is controlling the metabolism of energy in the cells [1-3]. Besides that, the expression of UCP2 is associated with chronic inflammation due to reactive oxygen species (ROS). In this regard, in injured cells and tissues, ROS could be decreased by reducing the proton motor force by the anti-inflammatory effect of UCP2 [4].

Oxygen therapy is the main supportive treatment in hypoxemic respiratory failure and has traditionally been delivered using low and high flow devices. However, the maximal flow rates that these devices can deliver are limited because of the insufficient heat and humidity provided to the gas administered. Low flow devices such as the nasal cannula, conventional face mask and reservoir bag deliver a flow rate of up to 15 L/min by administering more variable oxygen fractions (FiO2), depending on the patient’s respiratory pattern, peak inspiratory flow and characteristics of the devices. Conventional high flow devices, such as venturi type masks, utilize a constant flow of oxygen through precisely sized ports, entraining the ambient air, using the Bernoulli principle, providing a more constant inspired oxygen fraction. However, they are less tolerated than nasal cannulas because they are less comfortable and the insufficient humidification and heating of the gas delivered [1]. In the last two decades, new devices have been developed to administer high humidified and heated flow through a nasal cannula (HFNC) that also allows the delivery of oxygen with a known FiO2 up to 100%. In the literature, this technique has also been called mini CPAP (continuous positive airway pressure), transnasal insufflation, high nasal flow ventilation, high flow oxygen therapy, and high flow nasal cannula oxygen therapy [2]. It is considered that high flow nasal cannula has certain benefits compared to those of oxygen therapy previously detailed. HFNC manages a flow of more than 30 L/min, which is able to surpass the peak inspiratory flow of the patient, being able to reach values ​​between 60-80 L/min depending on the flow used. The gas source, which may be delivered by an air/oxygen blender, fans, or a flow generating turbine, is connected by an active humidifier to a nasal cannula and the FiO2 can be adjusted independently of the flow. From a clinical point of view, there is some confusion between venturi and high flow nasal cannula devices. In the literature, both have been considered as high flow oxygen therapy devices. In our opinion this is not appropriate because the high nasal cannula flow is much more than a simple system for administering oxygen therapy [3]. Venturi-type masks provide the patient with a gas mixture with a controlled FiO2, but do not exert additional benefits on the ventilator mechanics of the patient. Nevertheless, HFNC allows the delivery of a high flow, which can also add oxygen therapy, providing a series of physiological effects that imply an active treatment to respiratory failure. Effects related to HFNC include the following: 1. Delivery of higher and more stable FiO2 values, ​​because the flow delivered is greater than the patient’s inspiratory demand. 2. The anatomical dead space decreases by washing the nasopharynx, consequently increases alveolar ventilation. This improves the thoracoabdominal synchrony. 3. Respiratory work decreases because it acts as a mechanical stent in the airway and markedly attenuates inspiratory resistance. 4. The gas administered is warmed and humidified, improving mucociliar clearance, reducing the risk of atelectasis, improving ventilation perfusion and oxygenation ratio. 5. There is a CPAP-like effect. The dynamic positive espiratory airway pressure generated by HFNC reaches a value between 6-8cmH2o depending on the flow and the size of the cannula. This positive pressure distends the lungs and ensures their recruitment. 6. Pulmonary end-expiratory volume is higher with HFCN than with conventional high-flow oxygen therapy. 7. In addition, the technique is considered easy and simple for the medical staff and nurses, and can be used in different areas (emergency, hospitalization, critical care unit, weaning centers) and even at home [4]. Currently available evidence has demonstrated that HFNC therapy is an alternative for the treatment of acute hypoxemic respiratory failure, hypercapnic respiratory failure, acute heart failure, as rescue therapy preventive therapy in post-extubation respiratory failure and in specific conditions such as bronchoscopy [5]. We believe that high-flow nasal cannula treatment should not be confused with high flow oxygen therapy of venturi masks. According to detailed mechanisms of action, HFNC is not limited to being only an oxygen therapy system but also behaves as a true treatment that can be used in different clinical scenarios, generating physiological benefits that result in the reduction of respiratory work. In addition, in venturi type masks, the air is not humidified and complications such as dryness and nasal pain are common, generating a poor tolerance to oxygen therapy. The benefits of proper humidification and heating of the gas delivered with HFNC therapy allow better comfort and tolerance of the patient with easy adherence to the treatment. All this contributes to making HFNC be considered a technique of choice in patients with hypoxemic respiratory failure. The growth in its use associated with easy acceptance for patients and the expansion in its application show us that HFNC is a promising therapy.

The shoulder is the greatest movable joint in the human body. Its anatomical design allows a wide range of motion in all directions, leading to an insubstantial balance between stability and mobility. Conservative treatments are suggested by a number of authors for restoring the scapular dyskinesis. However, this condition can be overlapped by other clinical findings. Therefore, comprehensively analysing individual biomechanical rationale is central to design the ideal rehabilitation regimen to overcome scapular dyskinesis by restoring the scapular thoracic rhythm and preventing the associated problems. This study presents a brief clinical series of three patients with shoulder pain due to the alteration of their scapulahumeral rhythm and highlights a comprehensive examination and follow up an evidence-based rehabilitation algorithm to regain pain free functional ability in daily routine life.

Since December 2019, an outbreak of novel corona virus disease was reported in Wuhan, which has subsequently affected more than 160 countries worldwide. The ongoing outbreak has been declared as a pandemic by WHO, a global public health emergency. Several countries are successfully fighting with the pandemic by taking strict measures like nationwide lockdown or by sequestering the areas that were suspected of having risk of community spread. The corona virus pandemic has upended our educational system worldwide [1-3]. The academic calendar all over the world has been disturbed as a result of lockdown. Even after lockdown it would take probably many more months for universities, colleges and schools to reinstate. Caught in the turmoil, some parts of urban Indian education system have turned towards delivery of education via internet or online education. The NCAER skills report 2018 discussed the immense potential of online learning, conversely as complementary to more traditional methods. Centuries old, lecture based approaches, institutional biases, and outmoded classrooms changed. Covid 19 has become an impetus for educational institutions worldwide to search for innovative solutions in a relatively short duration. In the prevailing situation, online education is turning out as an alternative to traditional modes [2,4,5]. Contemporary/E-learning prepares students across all curriculum and learning stages with skills and potential to flourish in a rapidly changing and interlinked world. It connects students and engages their sense of inquisitiveness. E-teachers know and understand the needs and talents of their students. They are trained, flexible and select from a wide range of effective teaching strategies based on need. The new learning environment and resources galvanize students to be leaders of their independent learning. Thus students collaborate and use critical and creative thinking to solve complex problems and become apprehensive and sentient global citizens [4-6]. In physiotherapy, apart from traditional institution based learning, there implies a need for technological inputs and E-learning as a need to develop critical, creative thinking and reasoning. These technological arrays do provide better concepts and understanding regarding academics and practice [6]. As physiotherapy is advancing and growing in academics, research and practice, the need for an interlinking platform through which learning becomes unconditional and globally accessible was never addressed. Covid- 19 lockdown and strategies imposed us to think apart from institutional mode, ostensibly got a worldwide acceptance. Research suggests that online learning has been shown to increase retention of information, and take less time. On average, students retain 25% - 60% more information when learning online compared to only 8% - 10% in a classroom. E-learning requires 40-60% less time to learn and understand than in a traditional setting, because students can learn at their own pace, re-reading, skipping or accelerating through concepts as they choose. Contemporary learning or E-learning at present situation is intended to have the desired effect such as physical distancing, schedule flexibility, cost effective, fast learning, course variety, boost memory, reasoning and innovative teaching [2,4]. Adoption of online learning will continue to persist post pandemic, and how such a shift would impact the worldwide education market should be studied. Some believe that the unplanned and rapid move to online learning with no training, insufficient bandwidth, and inadequate preparation will result in a poor user experience that is deleterious to sustained growth [5,8]. The current crisis has acted as a thwack to encourage digital education among physiotherapy institutions. However, to achieve its prospective in the long run, physiotherapy institutions and universities should implement a digital platform, training as well as a curriculum regulation. “We believe that, the integration of information technology, E-learning in education will be further accelerated and eventually transpire to an integral component of physiotherapy education and practice”.

Two of the most recent LABA/ICS combinations for treatment of persistent asthma are Fluticasone furoate/Vilanterol 92/22 µg (Ellipta) and Beclomethasone dipropionate/Formoterol 100/6 µg (Nexthaler). Objective: To compare once-daily Fluticasone/ Vilanterol combination with twice daily Beclomethasone/ Formoterol association in moderate asthma, in terms of quality of life and lung function. Methods: Fourty patients with moderate asthma treated with Beclomethasone/Formoterol 100/6 µg or Fluticasone/Vilanterol 92/22 µg. We revalued patients in terms of lung function and Asthma Control Test, at 4, 8 and 12 weeks to assess any differences between the two groups. After 4 weeks, thirty-one of the fourty patients were evaluated in terms of respiratory function at predetermined time intervals. Result: In patients treated with beclomethasone/formoterol FEV1 presented a mean value of 78% at the third visit and of 79.1% during the final check, compared with 74.5% and to 75.8% in patients in treatment with fluticasone/vilanterol (p 0.01). Mean values of IC and MMEF25-75% were higher in patients treated with beclomethasone/formoterol compared with fluticasone/vilanterol. For the dyspnea it was a difference at the third observation. For the nocturnal symptoms and the use of rescue drug there was a significant difference, except at the beginning. For the perception of control by patients, there was a difference in the two groups at the beginning, after 4 and 8 weeks. Total ACT score showed a significant difference after 4, 8 and 12 weeks. In the group treated with beclomethasone/formoterol FEV1 value was significantly higher at a distance of four hours after drug administration (p 0.04) and after the second dose (p 0.02) compared with the group treated with fluticasone/vilanterol. Discussion: Patients in treatment with beclomethasone/formoterol showed improved asthma control and nocturnal symptoms and more stable respiratory function compared with patients receiving fluticasone/vilanterol.

Chemotherapy is one of the main treatment options for cancer. However, chemotherapeutic agents usually suffer from poor pharmaceutical properties that restrict their use. Targeted therapy drugs have been developed to specifically target changes in cancer cells that help these cells to grow. Such drugs often work when standard chemotherapeutic drugs do not, they often have less severe side effects and they are most often used for advanced cancers. The objective of this article is to give an overview about the 16 FDA-approved targeted therapy drugs to treat non-small cell lung cancer.

With the invention of the stethoscope, in the early 1800s, a better diagnosis of heart and lung disorders was opened up. Through the stethoscope's 200-year history, there has been a significant development of the stethoscopy from the use of the simple monaural earpiece to the binaural stethoscope, followed by the electronic stethoscope, which, together with other studies, has enabled a thorough diagnosis of these disorders. Here is a glimpse of this story. The cross-border investigation Far back in time, it has been clear that the function of the heart and lungs played an important role in maintaining life. By tapping with the finger (percussion) and putting the ear to the patient's chest (auscultation), it could hear sound from the body telling about the patient's condition, especially about the presence of fluid or air-filled organs. Auscultation is already described in the Corpus Hippocraticum, in the Diseases II section [1]. The doctor puts the ear to the chest of a patient with water sores, to hear the pain as a wine vinegar from the lungs - or the doctor grabs the patient about the shoulders, shakes him and places his ear to his chest to hear in which side his pleuritis is sitting. Since then, auscultation seems to have been partially forgotten, although it has probably been known by Ambroise Paré and William Harvey [2]. It was not until the late 1700s that it became an important diagnostic aid, just like the pulse clock and the medical thermometer [3 p. 277]. Here, Joseph Leopold Auenbrugger (1722-1809) is considered to be the father of the modern physical examination, which is based on percussion. Percussion he performed by knocking direcly on the thorax with the finger or cupped hands. His discovery of the percussion sounds from the chest during inhaling and exhaling originates from his work in 1760 at the Vienna Military Hospital [4]. In 1761, His little book on thoracic percussion revealing thoracic diseases appeared in 1761 [3p.271], which in 1808 was translated into French by the Parisian physician Jean Nicolas Corvisart des Marets (1755-1821). This contributed to the French doctors starting to use percussion and ausculation more routinely [5]. The limitation of simple auscultation was the fact that the sound was weak and incomplete and therefore there was a need for improved sound quality. In addition, the direct contact with the patient's body could seem insulting

Introduction: Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis (Bacillus of Koch), and presents chronic evolution affecting the lungs frequently. Objectives: Analyse, in the state of Maranhão, the epidemiological prevalence of tuberculosis between 2014 and 2016. Materials and Methods: Documentary and descriptive study of secondary data collected in the database of the dates, epidemiological information and morbidities, between 2014 and 2016. Results: 3,897 cases of tuberculosis in the state of Maranhão were recorded. The most affected age range was 15 to 59 years, totaling 3,111 cases, for both gender; of 60 to 79 years, 577 cases were totaled. Conclusion: Tuberculosis affects more adolescent males from adolescence to old age, and it is necessary to promote knowledge of the disease for the population in order to advance in the control of the same and obtain satisfactory clinical results.

Introduction: The disease outbreak of COVID-19 has had a great clinical and microbiological impact in the last few months. In the preanalytical phase, the collection a sample from of a respiratory tract at the adequate moment and from the correct anatomical site is essential for a rapid and precise molecular diagnosis with a false negative rate of less than 20%. Materials and methods: We conducted a descriptive study of COVID-19 disease with a persistently negative RT-PCR test in patients seen at the National Institute of Respiratory Diseases (INER) in Mexico City in the period of March through May of 2020. 38 patients were registered with negative RT-PCR test obtained through nasopharyngeal and oropharyngeal swabbing. We evaluated the distribution of data with the Shapiro-Wilk test of normality. The non-parametric data are reported with median. The nominal and ordinal variables are presented as percentages. Results: The average age of our cohort was 46 years and 52.63% were male (n = 20). Diabetes Mellitus was documented in 34.21% (n = 13) of the patients, Systemic Hypertension in 21.05% (n = 8), Obesity in 31.57% (n = 12) and Overweight in 42.10% (n = 16). Exposure to tobacco smoke was reported in 47.36% (n = 18) of the patients. The median initial saturation of oxygen was 87% at room air. The severity of the disease on admission was: mild 71.05% (n = 27), moderate 21.05% (n = 8) and severe or critical in 7.89% (n = 3) of the cases respectively. 63.15% (n = 24) sought medical care after 6 or more days with symptoms. Lymphopenia was documented in 78.94% (n = 30). Median LDH at the time of admission was 300, being elevated in 63.15% (n = 24) of the cases. The initial tomographic imaging of the chest revealed predominantly ground glass pattern in 81.57% (n = 31) and predominantly consolidation in 18.42% (n = 7). The registered mortality was 15.78% (n = 6). Conclusion: Patients with COVID-19 and a persistently negative RT-PCR test with fatal outcomes did not differ from the rest of the COVID-19 population since they present with the same risk factors shared by the rest of patients like lymphopenia, comorbidities, elevation of D-Dimer and DHL on admission as well as a tomographic COVID-19 score of severe illness, however we could suggest that the percentage of patients with a mild form of the disease is higher in those with a persistently negative RT-PCR test.

The harmattan season, which is a period characterized by low temperature, dry air and increased air pollution leads to widespread airborne disease and exacerbation of pre-existing conditions, should be recognized as a period of potential risk of high COVID-19 infection rates. This period also coincides with the Christmas season which comes with so many festivities and can become a COVID-19 super-spreader. With many Nigerians now abandoning the non-pharmaceutical protection measures against COVID-19, the harmattan season and the forthcoming spike in social gatherings might usher in the second wave of the virus which can potentially be more catastrophic. There is need for the Nigerian government to start planning and instituting new protection measures and guidelines for safe Christmas celebration while also educating and encouraging the populace to adopt the protection measures recommended by experts.

Chronic fatigue syndrome (CFS) is a poorly-understood respiratory condition that affects millions of individuals. Hyperbaric oxygen therapy (HBOT) is a treatment option being considered to address CFS as it is suggested to combat fatigue and increase oxygenation. HBOT provides two opportunities in advancing research of CFS: it may provide data on symptom amelioration and be utilized in the search for a biomarker. By either identifying biomarkers before using HBOT to compare epigenomes of patients before and after treatment or using HBOT to find epigenetic discrepancies between patients with and without treatment, matching epigenetic regulation with symptom amelioration may significantly advance the understanding of the etiology and treatment mechanism for CFS. EPAS1/HIF-2α is a leading candidate for an epigenetic biomarker as it responds differentially to hypoxic and normoxic conditions, which degrades more slowly in hypoxic conditions. Epigenetic regulation of EPAS1/HIF-2α in such differential conditions may be explored in HBOT experiments. In addition to HBOT as a promising treatment option for CFS symptoms, it may aid the identification of biomarkers in CFS. Further research into both outcomes is strongly encouraged.

Introduction: the perennial pandemic: There are serious challenges posed by the SARS-CoV-2 virus and COVID-19 as the disease. With the persistence of the pandemic over one and half year, it is being feared that the COVID-19 may have become the new reality associated with human existence world over and the mankind may have to live with it for years or even decades. Further, the grievous nature of the disease is evolving further with genomic changes in the virus in form of mutations and evolution of variants, with enhanced infectivity and probably virulence. Acute and chronic phases of COVID-19: Epidemiologically, it is becoming clear that apart from the advanced age and pre-existing conditions, such as diabetes, cardiovascular, pulmonary, and renal diseases, certain constituent factors render some patients more vulnerable to more severe forms of the disease. These factors influence the COVID-19 manifestations, its course, and later the convalescence period as well as the newly defined ‘Long COVID phase. The substantial continuing morbidity after resolution of the infection indicates persisting multisystem effects of ‘Long Covid’. Lung damage associated with COVID-19: COVID-19 is primarily a respiratory disease presenting with a broad spectrum of respiratory tract involvement ranging from mild upper airway affliction to progressive life-threatening viral pneumonia and respiratory failure. It affects the respiratory system in various ways across the spectrum of disease severity, depending on age, immune status, and comorbidities. The symptoms may be mild, such as cough, shortness of breath and fevers, to severe and critical disease, including respiratory failure, shock, cytokine crisis, and multi-organ failure. Implications for the post-COVID care: Depending on the severity of respiratory inflammation and damage, as well as associated comorbidities, duration of injury and genetics, the progressive fibrosis leads to constriction and compression of lung tissues and damage to pulmonary microvasculature. Consequently, the COVID-19 patients with moderate/severe symptoms are likely to have a significant degree of long-term reduction in lung function. Depending on the severity of the disease, extensive and long-lasting damage to the lungs can occur, which may persist after resolution of the infection. Managing the long COVID’s challenges: Given global scale of the pandemic, the healthcare needs for patients with sequelae of COVID-19, especially in those with lung affliction are bound to increase in the near future. The challenge can be tackled by harnessing the existing healthcare infrastructure, development of scalable healthcare models and integration across various disciplines with a combination of pharmacological and non-pharmacological modalities. Following clinical and investigational assessment, the therapeutic strategy should depend on the disease manifestations, extent of damage in lungs and other organs, and associated complications.

This case shown here represents a rare situation where the breast implant is spontaneously and inadvertently migrated from its submammary position via the thoracic wall into the ipsilateral pleural cavity after performing an ipsilateral thoracotomy due to atypical wedge resection of the right upper lobe four months ago. Intraoperatively, the implant has been neither dislodged nor manipulated in any way. In the literature, there are some sparse case descriptions where such breast implant migrations are encountered after VATS procedure (video-assisted thoracoscopy) [2] and open thoracotomy surgery [3]. Interestingly, our case report is quite similar to those which was published by Dutch colleagues in 2014 [4]. Considering the etiology and pathomechanism of such an implant migration as shown here, there is a common agreement that both a leakage of the implant´s fibrous capsule and an operative transection of the intercostal thoracic wall are prerequisite to create a potential migrating pathway to allow implants moving towards the pleural cavity [5]. Additionally, it is believed that the negative pressure within the pleural cavity also alleviates the unidirectional herniation by “sucking in the implant” into the interpleural space [6]. Sometimes, external repetitive pressures such as stretching massages may cause or trigger such an implant dislocation. Furthermore, there are cases described in which, seemingly, implant migration does occur without known preceding thoracic surgery [7]. Eventually, there are cases published in the literature with intrapleural spreading of disrupted breast implant debris [8]. With our patient, thanks to the absence of any discomfort or pain, it was concluded after agreed statement of an interdisciplinary round table discussion not to remove the dislocated implant surgically because of potential intercostal tissue damage and subsequent pain to await. More astonishing, the clinicians involved in this case wondered the fact that the missed implant of her right breast remained either unnoticed or has been completely neglected by the female patient. In this short communication, we present a rare and unusual case of an obviously vanishing breast implant which is found to be inadvertently migrated into the adjacent pleural space after undergoing thoracic surgery. According to common legal policy at our institution, an approval for case reports is generally provided as it was obtained in this particular case.

Introduction - evolution of SARS-CoV-2 variants: With the unrestrained pandemic for over last one-and-half year, SARS-CoV-2 seems to have adapted to its habitat, the human host, through mutations that facilitate its replication and transmission. The G variant incorporating D614G mutation, potently more transmissible than the ancestral virus arose during January 2020 and spread widely. Since then, various SARS-CoV-2 variants of concern (VOCs) and variants of interest (VOIs) with higher infectivity or virulence or both, have evolved on the background of G variant, and spread widely. SARS-CoV-2 infection and the immunodynamics: As the virus becomes more transmissible, its lethality may drop. Apart from the humoral immunity, T-cell recognition from a previous SARS-CoV-2 infection or vaccination may modify the disease transmission correlates and its clinical manifestations. On the other hand, the immunity generated may reduce probability of re-infection as well as limit evolution of adaptive mutations, and emergence of highly infectious and immune-escape variants. There are complex issues related to the SARS-CoV-2 evolutionary dynamics and host’s immunodynamics. Trending etiopathoimmunological correlates: The evolution potential of SARS-CoV-2 is limited because of proofreading function of nsp14. The S protein mutations affect transmissibility, virulence, and vaccine efficacy. The D614G mutation in G variant with higher infectivity has turned the Chinese epidemic into a pandemic. Other SARS-CoV-2 variants, such as Alpha, Beta, Gamma, and Delta seem to have evolved as result of adaptation to selective pressures during periods of prolonged infections and subsequent transmission. Further, there is issue of convergent association of mutations. Basics of immunity and immune system failure: The nature of the immune response after natural SARS-CoV-2 infection is variable and diverse. There are pre-existing neutralizing antibodies and sensitized T cells elicited during previous infection with seasonal CoVs influencing the disease susceptibility and course. The virus has evolved adaptive mechanisms to reduce its exposure to IFN-I and there are issues related to erratic and overactive immune response. The altered neutralizing epitopes in the S protein in SARS-CoV-2 variants modify the immune landscapes and clinical manifestations. Conclusion: current scenarios and prospects: Presently, the SARS-CoV-2 infection is widespread with multiple evolving infectious variants. There is probability of its transition from epidemic to endemic phase in due course manifesting as a mild disease especially in the younger population. Conversely, the pandemic may continue with enhanced disease severity due to evolving variants, expanded infection pool, and changing immunity landscape. There is need to plan for the transition and continued circulation of the virus during the endemic phase or continuing pandemic for indefinite period.

Morgagni hernia represents 2-4% of congenital diaphragmatic hernias. Only one-third of them are symptomatic, due to the hernia of abdominal viscera in the thoracic cavity, causing respiratory and digestive problems, some of them serious ones, such as intestinal obstruction. Acute presentation with incarceration of the contents is rare; there are only 7 cases described in the literature. We are presenting a case of diaphragmatic hernia that began with obstruction of the colon and secondary ischemia, requiring emergency surgery in two phases: first surgery to control the damage, with an open right hemicolectomy, and then later surgery to repair the hernia and perform bowel transit reconstruction, with proper postoperative evolution and no evidence of relapse. The treatment of Morgagni diaphragmatic hernia is surgical. Also in asymptomatic cases, due to the risk of incarceration, the most appropriate way to enter is abdominally, whether by way of laparotomy or laparoscopy, for the reduction of the contents of the hernia sac, the repair of the defect, as well as the performing of associated techniques on herniated viscera, as occurred in our case. A complicated congenital hernia is an infrequent pathology, and there is little experience in handling it. Acute presentation requires a combined treatment of the abdominal symptoms and repair of the hernia defect. The carrying over of surgical techniques for damage control into non-traumatic surgery in the face of serious hemodynamic instability is a widespread, accepted practice with the benefits of reducing mortality in critical patients and at times allowing the avoidance of ostomies.

From the first case of primitive cardiac surgery (CS), treatment of stab wound of the heart (Dr. Daniel Hale Williams, 1893), to recent surgical procedures and device implantations for end-stage heart failure (HF), the CS has grown and emerged in the public health more and more [1]. The heart valve disease had interested immediately since the non-cardiopulmonary era because of the multitude of rheumatic patients and congenital valve disease. In the 1952, Hufnagel implanted the first valve in descending aorta and it was the sign of the first step of the CS evolution. New prosthesis and heart valve techniques were tested between 1970 and 2000 with optimal results in patients’ quality of life and survival, at the same time of CPB evolution. Whilst, the evolution of heart valve surgery had stimulated new devices, prosthesis and the development of minimally invasive surgery, this was partially diminished by the spreading of trans catheter valve implantation. In the 2002, Dr. Alain Crabbier described a non-surgical prosthetic valve implantation firstly: it was the revolution of CS evolution [2]. The transcatheter valve implantation has evolved and spread rapidly with multiple approaches femoral to apical, aortic, axillary and carotid, and many suitable and technological devices. The higher and higher risk patients, the needs to avoid surgical complications, the evolution of available devices and the fabrication of new technologies have increased the efforts to improve trans catheter valve implantation [3]. The recent article of Loyalka et al, described a special case of tricuspid valve in valve replacement with Sapien 3, an innovative and alternative therapeutic choice to a tricuspid valve degeneration [4]. Instead, Sawara et al [5], documented as trans catheter aortic valve implantation for a failing surgical bio prosthesis or native aortic valve regurgitation has become an alternative for patients at high risk for redo surgical aortic valve replacement or aortic regurgitation since now off-label: that was a reliable and significant results in the era of trans catheter valve implantations. What would we attend from the future? In the most surgical centres, the trend were a significant decrease in patients undergoing to open-heart valve surgery compared to trans catheter valve implantation. Maybe the new ongoing studies of lower and mild-risk patients undergone to transcatheter procedure would open either a deeper collaboration of the heart team and a new therapeutic perspectives in the public health with a shift to more minimally invasive procedures, less day of hospitalization and I don’t see why not less costs for public health.

Introduction: Laparoscopic approach is emerging as a standard of care approach for management of masses amenable to partial nephrectomy. Laparoscopic partial nephrectomy is a challenging surgery and its successful performance depends on various factors. We aim to evaluate the influence of tumor characterestics on the operative performance for laparoscopic partial nephrectomy. Methods: Patients undergoing laparoscopic partial nephrectomy in our institution were recruited for this study. The tumor profile was evaluated by a senior radiologist from cross sectional imaging (computed tomography or magnetic resonance imaging). Tumor characerestics was defined by assessing tumor size, tumor location and RENAL score. The operative performance was evaluated in terms of warm ischemia time, blood loss, operation duration and any significant operative complications. Statistical inference was drawn. Results: 37 patients who underwent laparoscopic partial nephrectomy between January 2010 and June 2012 were included in this study. The mean tumor dimension was 3.81 cms. 21 tumors involved left kidney and 16 involved right kidney. 12 were located in upper pole, 8 were located in midpole and 17 were located in lower pole. The average RENAL score was 6.56. The mean warm ischemia time, blood loss and operation duration was 26.29 minutes (min), 256.76 millilitres (ml) and 208.11 min respectively. Statistically significant correlation was appreciated between tumor location (polar location, side, anterior/ posterior location) and RENAL score and operative parameters (warm ischemia time and operation duration). Tumor size did not have any correlation with the operative parameters. Conclusion: The operative performance of laparoscopic partial nephrectomy is significantly influenced by the tumor location and RENAL score.
