Background: Around 75% of seniors seeking treatment for injuries in Emergency Departments (ED) are discharged home with minor injuries that put them at risk of functional decline in the following months. Objectives: To 1) describe seniors’ characteristics using or not physiotherapy services following ED visits for minor injuries and 2) examine their functional status according to physiotherapy use. Methods: Secondary data analyses of the Canadian Emergency Team Initiative cohort study. Participants were 65 years and older, discharged home after consulting EDs for minor injuries and assessed three times: ED, 3- and 6-months. Physiotherapy use was recorded as yes/no. Functional status was measured using the Older American Resources Scale (OARS). Multivariate linear regressions were used to examine change in OARS scores over time, accounting for confounders. Results: Among the 2169 participants, 565 (26%) received physiotherapy, and 1604 (74%) did not. Physiotherapy users were more likely females (71% vs. 64%), more educated, and less cognitively impaired. The overall change in OARS at 6 months was -0.31/28 points (95% CI: -0.55; -0.28) with no difference across groups after adjustment. Subgroup analyses among frail seniors showed that physiotherapy users maintained their function while non-users lost clinically significant function (-0.02 vs. -1.26/28 points, p = 0.03). Among the severely injured (Injury Severity Scale ≥ 5), physiotherapy users’ results were higher by almost 1/28 points (p = 0.03) compared to non-users. Conclusion: These results suggest that among seniors discharged home after consulting the ED for minor injuries, the frail and severely injured may benefit from being systematically referred to physiotherapy services. 

Introduction: Minimal change disease (MCD) is a common subtype of primary nephrotic syndrome in adults. The pathogenesis of MCD is still not well understood, but some studies suggest that MCD is a T cell-mediated disease related to podocyte dysfunction. Previous research has also indicated the crucial role of B cells in the pathogenesis of MCD. Rituximab (RTX) is a recombinant chimeric mouse/human antibody targeting CD20 antigen. In recent years, RTX has been increasingly used in adult MCD patients.Methodology: We searched the PubMed database using the keywords “Minimal change disease”, “Nephrotic syndrome”, and “Rituximab” and obtained a total of 140 articles. We will now provide a literature review based on these 140 articles, according to our research topic.Discussion: This article provides an overview of the mechanisms and clinical research progress of RTX in the treatment of adult MCD. We have also discussed the current treatment methods for MCD, exploring the potential of using RTX as a first-line therapy for refractory adult MCD.Conclusion: MCD is a common pathological type of nephrotic syndrome, and the exact mechanisms are still not fully understood. Although RTX as a treatment of adult MCD has shown promising clinical results in patients with refractory adult MCD, the safety and efficacy of RTX still lack high-quality clinical evidence. Further research is needed to explore the pathogenesis of MCD and the RTX treatment for MCD.

Brf1 (TFIIB-related factor 1) is a transcription factor, which specifically modulates the transcription of RNA polymerase III-dependent genes (RNA Pol III genes), such as tRNAs and 5S rRNA. The products of tRNAs and 5S rRNA transcription will be changed with the alteration of Brf1 expression. Whereas deregulation of Brf1 and RNA Pol III genes are tightly associated with cell proliferation and transformation, and tumorigenesis. In recent years, emerging studies indicate that Brf1 expression is increased in patients with cancers. In this review, we summarize the progress of the abnormal expression of Brf1 in different human cancers to explore an underlying mechanism and its clinical implication, as well as to prompt its application prospect. With the depth of the Brf1 study and the progress of biotechnology, the status of Brf1 expression may be used as a universal indicator of the early detection and prognosis observation of human cancers.

The global pandemic COVID-19, caused by SARS-CoV-2, affected millions of people. COVID-19 is known for its respiratory symptoms, but new research reveals it may also affect other organ systems, including the liver. This abstract reviews COVID-19 and liver function. The virus enters host cells through liver-expressed angiotensin-converting enzyme 2 (ACE2) receptors. Thus, viral infection and replication may target the liver. Virus-induced inflammation and cytokine production may also harm the liver. ALT and AST elevations are the most prevalent liver abnormalities in COVID-19 patients. Liver function test abnormalities frequently indicate serious illness and poor clinical outcomes. COVID-19 may worsen pre-existing liver diseases such as NAFLD and chronic viral hepatitis. Drug-induced liver damage (DILI) from COVID-19 therapies including antivirals and corticosteroids complicates liver complications care. Recent investigations have also shown that COVID-19 may cause long-term liver damage. In conclusion, COVID-19 infection, immune-mediated damage, and treatment problems may severely compromise liver function. Optimizing patient treatment and discovering targeted medicines requires understanding COVID-19's liver role. To reduce the effects of COVID-19 on liver function, further study is required to understand the mechanisms and long-term effects.

Photobiomodulation (PBM) is an effective method for treating neuropsychiatric diseases, yet its universal acceptance and utilization remain constrained. In this Letter to the Editor/Expert Opinion, we address the challenges confronting PBM researchers and pioneers, striving to establish universal confidence in its exclusive application for neuropsychiatric patient care. Despite encouraging animal experiments and selecting positive human clinical trial outcomes, PBM’s widespread acceptance of PBM is hindered by factors including limited clinical studies and clashes with established therapies, such as drug therapy and psychotherapy.To overcome these obstacles and broaden PBM’s adoption and application of PBM in neuropsychiatry, we propose a combinatorial therapy approach. By integrating PBM with interventions such as Cognitive Behavioral Therapy (CBT) or drug therapy, a cumulative effect can be attained, benefiting both patients and therapists. Patients gain access to diverse treatment options and experience synergistic effects of combined therapies, thereby enhancing outcomes. Therapists benefit from expanded intervention choices and improved quality of patient care.This study introduces a novel strategy of amalgamating PBM with recognized interventions, such as CBT and drug therapy, to address existing challenges. This combined approach offers a practical solution to augment PBM acceptance and usage in the realm of neuropsychiatry.To endorse this strategy, a shift in the research direction is imperative. Future studies should investigate the amalgamated use of PBM with other neurointerventions, such as CBT or drug therapy. Robust clinical trials contrasting groups like “PBM + CBT” and “PBM (sham) + rTMS” are vital to persuade clinicians and patients toward embracing combined PBM therapies.Although PBM’s eventual autonomy as a neuropsychiatric treatment is an overarching goal, the present combination therapy approach proves practical, inevitable, and mutually beneficial. By bridging conventional therapies with PBM, this strategy may facilitate wider acceptance and utilization in neuropsychiatry.

Background and aim: Preclinical in vitro and in vivo experiments suggest that radiation-induced tumour cell death can be enhanced 10- to 40-fold when combined with focused-ultrasound (FUS)-stimulated microbubbles (MB). The acoustic exposure of MB in the tumour volume causes vasculature perturbation, activation of the acid sphingomyelinase (ASMase) ceramide pathway, and resultant endothelial cell apoptosis. When the tumour is subsequently treated with radiation, there is increased endothelial cell death and anoxic tumour killing. Here we describe a first-in-human experience treating patients with magnetic resonance (MR)-guided FUS-stimulated MB (MRgFUS+MB) radiation enhancement.Case presentation: A head and neck cancer patient with recurrent disease underwent radiotherapy for 5 separate sites of locoregional disease followed by systemic therapy. The first consisted of a course of 45 Gy in 5 fractions alone, the second of 30 Gy in 5 fractions with hyperthermia, and the three others of 20-30 Gy in 5 fractions along with MRgFUS+MB treatment. The treatment methodology used an MR-coupled FUS-device operating at 500 KHz and 540 kPa peak negative pressure with an insonification time of 750 ms spread over 5 minutes to stimulate intravenously administered MB within tumour target. All sites treated with stimulated MB had a complete radiological response, and subsequently, the patient’s other cutaneous metastatic disease disappeared. The patient has been under surveillance for over two years without active treatment or disease progression.Discussion: MRgFUS+MB was well-tolerated with no reported treatment-related adverse events, which can be attributed to the capability of FUS to selectively stimulate MB within the tumour volume while sparing the surrounding normal tissue. Sustained local control at all target sites aligns with earlier preclinical findings suggesting the radiation enhancement potential of FUS+MB.Conclusion: MRgFUS+MB represents a novel and promising therapy for enhancing radiation efficacy and improving therapeutic index with potential improvements in disease control.

Pneumopericardium is a rare clinical entity, occurring in the setting of thoracic trauma, malignancies, or mechanical ventilation. Very few cases report pneumopericardium as a complication of gastrointestinal tract surgery. Signs and symptoms may be frustrating, ranging from asymptomatic to chest pain, sepsis, hemodynamic instability, pericarditis, or even cardiac tamponade. Clinical pathognomonic signs of pneumopericardium include pericardial metallic tinkling friction rub and mill wheel murmur. Diagnostic work-up includes electrocardiogram, chest radiography, and, computed tomography imaging. A gastro pericardial fistula should be considered a rare differential diagnosis for acute chest pain in patients with a history of gastroesophageal surgery. Rapid recognition and treatment avoid life-threatening complications. The successful outcome of gastro pericardial fistula treatment depends on both emergency and definitive surgical management. The survival rate with conservative management is poor.We present the case of a 78-year-old patient suffering from pneumopericardium and pericardial infusion, due to a fibrotic fistula between the Nissen’s valve, occurring 10 years after redo antireflux surgery. Treatment included broad-spectrum antibiotics, and emergency surgery for pericardial drainage, biopsy of the valve’s defect, suture, and omentoplasty.

Knowing the psychological traits and clinically relevant symptoms for the development and maintenance of Eating Behavior Disorders (EDD) in bodybuilding and fitness athletes is a necessity for early intervention and the elimination of stressors that contribute to improving sports performance and quality of life.The aim of the study: To know the dynamics of EDD and the level of general psychological adaptation in athletes who practice bodybuilding and fitness according to sports gender and age.By applying the Inventory of Eating Disorders, EDI-III on 30 participants, bodybuilding and fitness practitioners, aged between 19 and 53, of which 21 are male and 9 are female, psychological traits were investigated relevant (low self-esteem, perfectionism, asceticism, fear of maturity, interpersonal, emotional problems, exaggerated control, and others) in order to know the level of distress and the presence of clinically relevant symptoms for the development and maintenance of EDD (the desire to being thin, bulimia, body dissatisfaction)We concluded that most of the athletes fall within the limits of the threshold values ​​established for the evaluated scales, 30% of the athletes (3 female athletes and 6 male athletes), obtained scores rated above the threshold on at least one of the clinical scales, which means that the risk of EDD is present in some athletes. The average of the investigated psychological scales calculated for the rated scores to establish the level of general psychological adaptation does not exceed the specified threshold for each investigated dimension separately, except for the asceticism, interpersonal problems, and exaggerated control scales. Female athletes have greater psychological balance than male athletes and lower risk of ED than male athletes, important aspects of personality and mental health in psychological training as a screening tool in the process of optimizing the effectiveness of bodybuilding and fitness training.

Hypersexual disorder, also known as compulsive sexual behavior or sex addiction, is a complex and clinically significant condition characterized by intense and recurrent sexual fantasies, urges, or behaviors that significantly disrupt an individual’s daily life and overall well-being.

By exploring the multifaceted aspects of the condition, this review seeks to provide insights into effective treatment approaches and inspire further research in the study of hypersexual disorder.

This case suggests that POEMS syndrome does present with a constellation of signs and symptoms that may lead a clinician to a multitude of other possible diagnoses. Diagnosis is often difficult and delayed. A good history and physical examination as well as a careful review of all workups are paramount in establishing this particular diagnosis. The major criteria of diagnostic for the syndrome are polyradiculoneuropathy, clonal plasma disorder, sclerotic bone lesions, the presence of Castleman disease, and elevated vascular endothelial growth factor. Minor features include organomegaly, extravascular volume overload, endocrinopathy, characteristic skin changes, papilledema, and thrombocytosis. The diagnosis is made with three of the major criteria, two of which must include polyradiculoneuropathy and clonal plasma cell disorder, and at least one of the minor criteria. In this article, we discuss the differential diagnosis and outline the clinical evaluation indicated.

Background: Grand multiparty is common obstetrical problem, in Sudan large families is desirable for cultural and religious backgrounds and higher incidence of grandmultipra is expected, the risk factors associated with adverse maternal outcomes have yet to be adequately investigated among grand multiparity need to delivered by primary cesarean section.Objective: The main objective was to determine impact of primary cesarean section on grand multiparous, it is indications and complications.Methodology: It was a descriptive prospective cross-sectional hospital-based study conducted at Omdurman Maternity Hospital during period October 2016 to March 2017.An interview questionnaire was used for data collection.

Despite decades of global and country commitments towards eradicating malaria, malaria remains the most hazardous parasitic disease and the most common cause of fever for humans, especially in tropical countries. Plasmodium falciparum causes 90% of malaria cases. Coma [Cerebral Malaria (CM)], acidosis, hypoglycemia, severe anemia, renal dysfunction, and pulmonary edema are the most common complications of malaria caused by Plasmodium falciparum and the most common cause of death related to malaria. People from less prevalent malaria areas are at high risk of developing these complications. A 16-year-old male from a low malaria transmission area was diagnosed with CM. Prior to developing CM, he was treated with Coartem. CM is a medical emergency and one of the forms of severe malaria. CM has high mortality and morbidity rates. Yet, international health-related agencies, funders, and policy-makers are unfamiliar with it. The continuous occurrence of CM validates the considerable need for global investment in malaria control and elimination programs. Early administration of Artesunate to all patients suspected of having severe malaria would reduce global malaria-related mortality and morbidity. Simple tests, such as the determination of malaria parasitic density either with thin or thick blood smears, may influence the proper management of all severe malaria cases. However, in clinical practice, the determination of malaria parasitic density is not routinely done. Further commitments are needed to ensure routine determination of malaria parasitic density for all suspected severe malaria cases. Moreover, further commitments are needed to guarantee the proper management of CM because it is a major cause of reversible encephalopathy in tropical countries.

A 46-year-old lady was diagnosed clinically with X-linked hypophosphatemia (XLH) with a rare pathogenic variant detected using exome sequencing. Phosphate-regulating endopeptidase homologous X linked (PHEX) is normally expressed in osteoblasts and osteocytes, and senses phosphate regulation. More than 1000 PHEX variants have been detected to date, which are caused by missense, nonsense, and frameshift mutations in addition to splice variants and copy number changes. The aberration in the PHEX gene leads to the upregulation of fibroblastic growth factor 23 (FGF23), which leads to defects in phosphate metabolism. This results in impaired bone growth and mineralization, short and disproportionate stature, leg bowing, musculoskeletal pain, spontaneous dental abscesses, rickets, and osteomalacia in XLH patients. The spectrum of manifestations differs between pediatric and adult patients. In our case study, two of the patient’s children started showing symptoms at a younger age, unlike their mother. Timely diagnosis and the start of treatment would help in their better management and improved quality of life.

Hydrogel-based formulations hold significant promise for treating ocular diseases that impact the posterior segment of the eye. These formulations exhibit the ability to surmount ocular barriers and offer sustained drug release, rendering them efficacious drug delivery systems. This article addresses the challenges linked to treating disorders affecting the posterior eye segment and underscores the imperative for less invasive drug delivery methodologies. We further delve into diverse contemporary ocular dosage forms, encompassing gels, nanostructures, and implants, with a specific emphasis on hydrogels. Hydrogels offer several merits, including precise targeting, sustained release, enhanced bioavailability, and non-invasiveness. Moreover, they curtail the risk of adverse effects and foster patient adherence. An enthralling advancement is the amalgamation of hybrid drug delivery systems, integrating nanoparticles, liposomes, dendrimers, and stimuli-activated nano-systems, with hydrogels for posterior eye ailment treatment. These hybrid nano-systems exhibit promise in enhancing drug stability, prolonging drug release, and pinpointing specific tissues within the posterior segment. We also provide an overview of ongoing clinical trials and approved hydrogel-based drug delivery systems, like Retisert and Ozurdex. These systems have demonstrated efficacy in managing chronic non-infectious uveitis, Age-related Macular Degeneration (AMD), and diabetic macular edema. Nevertheless, challenges persist, including optimizing bioavailability, maintaining drug stability, and implementing personalized treatment approaches. The incessant evolution of gel-based drug delivery systems stands to substantially enhance patients’ quality of life and establish new benchmarks in treating posterior eye diseases. The future of ophthalmology brims with excitement, as gel-based drug delivery systems hold the potential to revolutionize ocular therapies, providing effective remedies for an array of vision-related afflictions.

Background: Inflammatory bowel disease (IBD) is characterized by non-specific chronic relapsing inflammation of the gastrointestinal tract and extra-intestinal manifestations. It includes Crohn’s disease (CD) ulcerative colitis (UC) and unclassified colitis.Objective: To assess the clinical presentations and management of inflammatory bowel disease in Sudanese patients.Methodology: Prospective, cross-section hospital-based study was conducted at Soba University Hospital (SUH) and Ibn Sina Hospital, in a period from December 2016 to March 2017. Data was entered and analyzed with SPSS, an interview questionnaire containing demographic, clinical, type of IBD, treatment, and complications.Results: A total of 64 IBD patients were included, 50% were diagnosed with UC, 28.1% with CD and 21.9% unclassified type. The most frequent age in UC patients was 41 – 50 years 34.4%, in CD was 31- 40 years 38.9% and for the unclassified type was 51 – 70 years 57.2%. The female was higher in CD while males were higher in Ulcerative colitis disease, symptoms were diarrhea, rectal bleeding, abdominal pain, rectal pain, tenesmus and fatigue. Study participants received 5 amino salicylic acid, and steroids, especially in the oral formulation. Minimal usage of topical forms, azathioprine, and biological agents. Conclusion: The study concluded UC is more common than CD. This should be taken into account as an important update for internal medicine professionals to adjust their expectations and lines of diagnosis, and management. The emergence of the unclassified type in Sudan requires good communication between the pathologists and the physicians and MDT meetings in every patient with suspicion of IBD.

Endometrial Stromal Sarcoma (ESS) is a rare gynecological malignancy originating from endometrial stromal tissue. Representing only a tenth of uterine malignant tumors, ESS is categorized into Low-Grade (LGESS) and High-Grade (HGESS) based on nuclear division. Interestingly, prognostic studies have found no strong correlation between ESS prognosis and nuclear division activity. Undifferentiated Uterine Sarcoma (UUS) represents a spectrum of tumors with varied morphological, clinical, and prognostic features, and lacks a standardized naming convention. In 2014, the World Health Organization grouped ESS into LGESS, HGESS, and UUS based on clinical and pathological attributes. HGESS, despite its rarity, is notorious for its poor prognosis and low survival rate. Its early detection is complicated due to its asymptomatic presentation and ambiguous pathogenesis, leading to debates over treatment approaches. This article delves into the recent research developments concerning HGESS.

Background: Although there is minimal information on the role of stress in PCOS, it is well-known that it may trigger the exacerbation and maintenance of the disease. Despite there being only a few studies in the literature, many researchers highlighted situations of autonomic hyperactivation characterizing PCOS. In light of these assumptions, the purpose of this study is to report on a patient who underwent psychological intervention to enhance stress management skills.Case: A 30-year-old woman was referred by the endocrinologist. From a clinical-psychological point of view, the condition of the patient was characterized by a modest psychophysiological activation. Interpersonal difficulties did not allow the patient to benefit from the social support of her loved ones, further favoring the maintenance of the excessive arousal generated by stressful life events. The patient was treated with HRV-Biofeedback integrated within cognitive-behavioral psychotherapy.Discussion: The multidimensional intervention brought benefits to the patient, teaching her better stress management strategies (i.e., reduction of psychological symptoms and improvement of hormonal tests). Keeping in mind the interplay between physiological, psychological, and interpersonal factors is fundamental in all psycho-somatic and somato-psychic disorders and is crucial to enhance the use of specific treatments to restore psychophysical well-being.

Background: Spirituality has been strongly associated with good blood pressure control as it forms a strong coping mechanism in hypertensive patients. This hospital-based cross-sectional study was done to determine the relationship between spirituality and blood pressure control among adult hypertensive patients in rural Southwestern Nigeria to achieve good blood pressure control.Method: The selection was done by systematic random sampling technique. Socio-demographic and clinical information were obtained through semi-structured interviewer-administered questionnaires. The level of spirituality was assessed using the Spiritual Perspective Scale. Data were analysed using the Statistical Package for Social Sciences version 20.0. Statistical significance was set at p ≤ 0.05.Results: The mean age of the respondents was 61.1 ± 11.1 years. More than half (52.6%) had a high level of spirituality and more than two-thirds (67.1%) of respondents had controlled blood pressure. Respondents with a high level of spirituality were 4.76 times more likely to have good blood pressure control {p < 0.001, 95% CI (1.05-14.99)} than those with a low level of spirituality. Conclusion: Proper understanding and effective utilization of this relationship will assist health professionals and researchers in the appropriate integration of this concept into patients’ holistic care with the aim of achieving better blood pressure control among hypertensive patients.

Introduction: Factor VII (FVII) deficiency, a rare bleeding disorder, can manifest as an autosomal recessive congenital or an acquired coagulopathy. Acquired FVII deficiency, although infrequently reported, presents unique challenges in understanding its mechanisms and identifying underlying causes. Case presentation: We present a case of acquired FVII deficiency discovered in a 23-year-old female patient with no apparent underlying disease. The patient exhibited spontaneous ecchymosis and gingival hemorrhage, along with low FVII activity and isolated prolongation of prothrombin time. Extensive laboratory investigations excluded liver dysfunction, familial deficiency, vitamin K deficiency, and inhibitory antibodies. Prompt treatment with Fresh Frozen Plasma (FFP) and bypassing agents resulted in a favorable response and resolution of hematomas. Conclusion: Acquired FVII deficiency was identified with bleeding symptoms in association with prolonged prothrombin time and a low level of FVII activity. In literature, this deficiency has been associated with various conditions such as sepsis, aplastic anemia, stem cell transplantation, and neoplasms, although approximately 14% of cases remain idiopathic. Clinical outcomes remain generally poor, with limited complete remissions reported.

Bone marrow and the central nervous system are both protected by bone. The two systems are interconnected not only structurally but also functionally. In both systems specialized cells communicate through synapses. There exists a tridirectional communication within the neuroimmune network, including the hormonal system, the immune system, and the nervous system. Bone marrow is a priming site for T cell responses to blood-borne antigens including those from the central nervous system. In cases of auto (self) antigens, the responses lead to immune tolerance while in cases of neo (non-self) antigens, the responses lead to neoantigen-specific T cell activation, immune control, and finally to the generation of neoantigen-specific immunological memory. Bone marrow has an important function in the storage and maintenance of immunological memory. It is a multifunctional and very active cell-generating organ, constantly providing hematopoiesis and osteogenesis in finely-tuned homeostasis. Clinical perspectives include mesenchymal stem cell transplantation for tissue repair within the central nervous system.
