Fibrinolytic therapy has become synonymous with tissue plasminogen activator (tPA) based on the belief that tPA alone was responsible for natural fibrinolysis. Although this assumption was belied from the outset by disappointing clinical results, it persisted, eventually causing fibrinolysis to be discredited and replaced by an endovascular procedure. Since time to reperfusion is the critical determinant of outcome, which in acute myocardial infarction (AMI) means within two hours, a time-consuming hospital procedure is ill-suited as first line treatment. For this purpose, fibrinolysis is more fitting. The assumption that tPA is responsible for fibrinolysis is contradicted by published findings. Instead, tPA ‘s function is limited to the initiation of fibrinolysis, which is continued by urokinase plasminogen activator (uPA) and that has the dominant effect. tPA and uPA gene deletion and clot lysis studies showed the activators have complementary functions, requiring both for a full effect at fibrin-specific doses. They are also synergistic in combination thereby requiring lower doses for efficacy. A clinical proof of concept study in 101 AMI patients who were treated with a 5 mg bolus of tPA followed by a 90 minute infusion of prouPA, the native form of uPA. A near doubling of the 24 h TIMI-3 infarct artery patency rate was obtained compared to that in the best of the tPA trials (GUSTO). In further contrast to tPA, there were no reocclusions and the mortality was only 1% [1]. A sequential combination of both activators, mimicking natural fibrinolysis, holds promise to significantly improve the efficacy and safety of therapeutic fibrinolysis.

Aims: Histological diagnostic criteria are used for the assessment of the degree of dysplasia and hence the risk of cancer progression for premalignant lesions. Clonal changes in the form of hyperorthokeratosis and hyperchromasia that are sharply demarcated from adjacent areas are not currently part of the criterion for dysplasia diagnosis. The objective of this study was to determine whether such clonal change should be regarded as a diagnostic feature for dysplasia. The following histological conditions were used to define such change: (1) hyperorthokeratosis; (2) hyperchromatism but no other features of dysplasia; (3) sharp margin demarcation from adjacent area by both the hyperorthokeratosis and hyperchromasia (clonal change), and (4) no prominent rete ridges, marked acanthosis or heavy inflammation. Lesions fitting these criteria were termed orthokeratotic lesions with no dysplasia. Methods: Patients from a population-based longitudinal study with more than 10 years of follow up were analyzed. Of the 214 patients with primary oral premalignant lesions, 194 had mild or moderate dysplasia (dysplasia group) and 20 fit the criteria for orthokeratotic lesions without dysplasia (orthokeratotic with no dysplasia group). The two groups were compared for their cancer risks using clinical (site and toluidine blue), histological (nuclear phenotype score), and molecular criteria (loss of heterozygosity) and by outcome (progression). Results and conclusions: The lesions from orthokeratotic with no dysplasia group showed a similar cancer risk (clinical, histological and molecular risk) and time to progression as the dysplastic lesions. We recommend that the clonal change should be included as a criterion for dysplasia diagnosis

Background: Premarital sexual practice significantly attributes for increase adolescent’s risk of unintended pregnancy, early marriage, abortion and STIs. In Ethiopia adolescents were intended to engage at early initiation to sexual intercourse without having proper protection has been one of the concerns. Study aimed to assess the prevalence of premarital sexual practice and associated factors among high school students. Method: A facilities based study design was employed. Data were collected from 291 randomly selected Negade and Finca Bamo high school students using structured questionnaire from June 1-30, 2018. Bi-variate logistic regression used to identify variables that crudely associated and variables with p - value < = 0.05 fitted to multiple logistic regression. Odds ratio with 95% confidence interval was estimated using multivariable logistic regression to identify independent predictors of premarital sex. Result: Among high school students, 31.2% reported had experienced premarital sexual practices. This shows that premarital sexual practices among high school adolescent’s students were high. Drinking alcohol [AOR = 4.06, 95%CI, (2.06 - 7.99)]. Watching pornographic video [AOR: 2.78, 95%CI, (1.45 - 5.3)] and educational status of mothers [AOR: 0.33; 95% CI (0.13, -0.84)] were significantly associated factors. Conclusion: Drinking alcohol, watching pornography and mother education were predominantly significantly associated. Therefore, an integrated effort needs to be highlighted to deter the health behavioral problems of school adolescents at the early stages. 

Microparticles (MPs) are considered important diagnostic biological markers in many diseases with promising predictive value. There are several methods that currently used for the detection of number and characterization of structure and features of MPs. Therefore, the MP detection methods have been remained pretty costly and time consuming. The review is depicted the perspectives to use coupling methods for MP measurement and structure assay. Indeed, there is large body evidence regarding that the combination of atomic force microscopy or coupling nanoparticle tracking analysis (NTA) with microbeads, plasmon resonance method and fluorescence quantum dots could exhibit much more accurate ability to detect both number and structure of MPs when compared with traditional flow cytometry and fluorescent microscopy. Whether several combined methods would be useful for advanced MP detection is not fully clear, while it is extremely promising.

Background: In 2004 we started a phase II trial in non-small lung cancer (NSCLC), stage III, with erlotinib followed by a combination with a platinum-based doublet in unselected patients to identify molecular subgroups benefitting from an EGFR targeting approach. Patients and methods: Induction with erlotinib (E, 150 mg, d1-42) was followed by three cycles of gemcitabine (G, 1250 mg/m², d1+d8, q3w) and cisplatin (P, 80 mg/m², d1, q3w). Patients with at least stable disease after E were treated with a GP + E combination. Induction was followed by surgery and radiation. The trial was conducted as a prospective, multi-center, open label, exploratory phase II study to determine pathological response rate (pRR), as well as secondary endpoints disease free survival (DFS) and overall survival (OS). Results: Of 38 prescreened patients 16 were included in the main study. Due to slow recruitment the study had to be terminated early. Combination of E and GP was well tolerated, surgery was feasible after induction therapy in 12 of 16 patients, 7/12 (58%) patients had a major pathological response (MPR). Median overall survival for patients with MPR was 57.7 months (confidence interval (CI), 37.4 to 78.0; n = 7) and for patients without MPR 11.9 months (CI, 6.4 to 17.4; n = 5). 2/16 patients had an epidermal growth factor receptor (EGFR) mutation. Conclusion: Before discovery of distinct molecular mechanisms in NSCLC our study was an attempt to identify clinical and pathological subgroups that would benefit from E induction. Two patients with an EGFR mutation were identified. MPR was a predictor of long term disease free and overall survival.

Levels of electrically evoked stapedial reflex thresholds (eESRTs) are frequently used as most comfortable levels (MCL) in cochlear implant fitting. The problem of routine one-channel-technique of reflexometry is long duration of this procedure. In order to “compress the time” we suggest method of consecutive stimulation of all electrodes of implant with simultaneous registration of stapedial reflexes-SWEEP-session. Practical implementation of the SWEEP-session is described here. This method has been successfully used in several hundred CI patients. Registration of evoked electrical stapedial reflex thresholds (eESRTs) during CI fitting is long procedure. In order to “compress the time” we suggest our SWEEP-session method. Practical implementation of this SWEEP-session is described here in accordance with the patent of Russian Federation.

Outbreaks of Ebola virus can cause substantial mortality in affected countries. The largest outbreak of Ebola to date is currently underway in West Africa, with 3944 cases reported as of September 5, 2014. For the sake of deriving a better understanding of the Ebola transmission dynamics, we have undertaken to revisit data from the initial spark of origin of the Ebola virus, which occurred in 1976 in Zaire (now Democratic Republic of Congo). By fitting a mathematical process to time series stratified by disease onset, outcome and source of infection, we have managed to estimate several epidemiological quantities, previously admitted to be too challenging to measure, including hospital and infected community contribution infection to the widespread transmission.

Aims and objectives: By reporting the use of therapeutic nursing interventions to facilitate the process of change in a depressive elderly caregiver, this paper seeks to underline the importance of fitting interventions to individual clients. Background: In assisting families of chronic illness sufferers, it must be remembered that the perceptions and functions of both clients and families are determined by family members, and that changes, if any, are made by those clients and families, rather than by nurses. However, nurses do play an important role in facilitating the process of change. Design: This is a case report. Methods: A case study of a depressive elderly caregiver is used to examine the use of therapeutic nursing interventions to facilitate the process of change with problem analysis, case conceptualisation and specific skills employed documented. Results: The change from one therapeutic approach (Cognitive-behavioural therapy) to another (Narrative Therapy) facilitates enlisting the caregiver’s unique strengths, resources and competence to overcome the difficulties and challenges identified during the process of change. In dealing with depression in family caregivers, nurses should not only be flexible but also remain sceptical in using different approaches, with heightened awareness of the client’s circumstances.

This study was carried out to investigate the rotational structure of even-even 166Hf isotopes using the phenomenological fitting, Sood’s semi-empirical formula. The rotational energies from the calculated values were compared to the experimental spectrum. The result shows that in 166Hf, calculated energies fit the experimental values to a remarkable degree of accuracy.

Objective: The FITT (Frequency, Intensity, Time, and Type) principle is an effective foundation in EP. However, the CORRECT components; C–Combination of interventions, O–Order of the Interventions, R–Repetitions, R–Rest period between sets and between sessions, E–Exercise at home, C–Cognitive domain, T–Total dose and re-evaluation plans, should be considered. The purpose of this paper was to describe the updated dynamic and evidence based FITT-CORRECT principle of EP and demonstrates its application using a case study. Results: Literatures, related to EP, clinical reasoning and clinical decision-making, were critically reviewed. Established evidence is summarized to describe an updated dynamic and evidence-based principle of EP. The gaps within the FITT and other related principles of EP are addressed. The FITT-CORRECT principle was introduced and an effective outcome of the updated principle was demonstrated using a case study. The FITT-CORRECT principle integrates many components that are missing in the FITT and other related EP principles. Based on the reported case study, the FITT-CORRECT principle of EP should optimize patients’ intervention outcomes. Physiotherapists can potentially improve their EP by utilizing the FITT-CORRECT in clinical practice.

Background: Corona virus disease is a highly infectious disease caused by the newly innovated corona virus. An emerging respiratory disease was abbreviated as COVID-19, after it has been first reported in December 2019 in Wuhan city of China. Ethiopia Ministry of health initiated multidisciplinary approach to tackle COVID-19 of which awareness creation is the main. The aim of this study is to assess knowledge, practice and associated factors towards prevention of novel corona virus among clients in Debre Tabor general hospital, Northwest Ethiopia, 2020. Methods: Institution based cross sectional study design was conducted in Debre Tabor General hospital from May 15 to May 30, 2020. A structured questionnaire was used for data collection. The data were entered into epi data version 4.4 and exported to SPSS window version 25 for analysis. Binary and multivariable logistic regression was fitted. Odds Ratios with 95% Confidence interval and p - value ≤ 0.05 were considered to assert significance. Result: A total of 345 clients were analyzed and the response rate was 96.4%. The mean age was 32.95 with S.D ± 13.18 years. Majority of the respondents were male (75.7%). Among the study participants 54.2% with (95% CI: [49.0, 59.2%]) and 49.0% with (95% CI: [43.5, 53.4%]) have good knowledge and god practice on COVID-19 preventions respectively. Sex AOR: 4.33 (2.06, 9.09), family size AOR: 2.49 (1.01, 6.15 and heard from social media AOR: 2.78 (1.21, 6.39) were significantly associated with knowledge of respondents. Knowledge AOR: 3.11 (1.59, 6.10) was significantly associated with practice of clients. Residency and those heard from TV were significant variables for both. Conclusion and recommendation: In this study the overall knowledge and preventive practices of the respondents were found to be low. Sex, family size, residency and sources of information were associated factors for knowledge. In addition to this knowledge was significant factor for practice. Health education programs aimed at mobilizing and improving COVID-19 related knowledge and practice intend to be strengthened.

Background: Acute kidney injury (AKI) is a major health problem affecting millions of people worldwide. Effective preventative and therapeutic treatments remain to be produced. We aim to determine the association between blood glucose and mortality in critical patients with AKI. Method: This cohort study included 18,703 patients with AKI. The exposure of interest was baseline blood glucose. The outcome was 30-day mortality. Multivariable Cox regression analyses and smooth curve fitting were adopted to assess the independent association between blood glucose and 30-day mortality. Results: We identified 18,703 consecutive individuals with AKI. The average age of the participants was 66.8 ± 16.0 years, and about 42.7% of them were female. The overall 30-day mortality was 16.9%. Through the multivariate COX regression model and smooth curve fitting, we observed that the correlation between blood glucose and 30-day mortality is nonlinear. An inflection point was found at about 5.93 mmol/L. On the left side of inflection point, the effect size was 0.81 (HR: 0.81, 95% CI 0.74-0.89, p < 0.001). On the right side of inflection point, the effect size was 1.02 (HR: 1.02,95% CI 1.01-1.03, p < 0.001). Conclusion: Our study suggested that, among patients with AKI, there was a nonlinearity relationship between blood glucose and mortality in patients with AKI. The optimal of blood glucose associated with the lowest risk of 30-day mortality was around 5.93 mmol/L. 

The increasing occurrence of wastewaters associated with industrial development has begotten a permanent search for new and more efficient techniques for the removal of hazardous substances such as heavy metals and dyes. The use of natural and available resources to develop improved and sustainable commodities for this purpose remains crucial and is among promising emerging green technologies for water treatment. It offers the gradual shifting of hazardous industrial chemicals precursors to the abundant non-metallic mineral resources that receive an added value. This work investigated the uptake capacity by the adsorption process of methylene blue (MB) and azocarmine G (AG) onto nano-silica synthesized from kaolinite clay. The effects of contact time (0-30 min), the adsorbent dosage (5-100 mg), the initial pH of the solution (1-11 for MB and 1-7 for AG), and the initial dye concentration (5-50 mg/L) were studied. The selected conditions to carry out kinetic and isotherm adsorption experiments were: 15 mins, 20 mg, 11 for MB, 1.01 for AG, and 50 mg/L. Four adsorption isotherms and three kinetic models were used to model the adsorption data thanks to linear and non-linear regression methods. From the obtained results, the Freundlich isotherm model fitted well the adsorption phenomenon while the pseudo-second-order kinetic model described well the adsorption mechanism. Furthermore, the free energy of adsorption was similar for the two absorbents, 0.71 kJ, pointing physisorption as the dominant adsorption mechanism. The optimum MB and AG uptake were respectively 13.8 and 36.1 mg/g. Conclusively, the nano-silica represents a potentially viable and powerful adsorbent whose use could lead to a plausible improvement in environmental preservation.

High fluoride level in drinking water is an endemic public health concern in East Africa. Unlike in Kenya where it is absent, the Nalgonda technique, a defluoridation method that uses two chemicals, alum, and CaO, has seen mixed results in its application and adoption in Ethiopia and Tanzania. This has been due to the low capacity of communities to manage the process and the breakdown in the supply chain of chemicals used in the technique. In the present study, we attempted to bridge the gap in the chemical deficit by investigating the possible substitution of CaO with leachate from wood ash, a by-product of wood combustion commonly found in Kenya. The leachate was prepared from one part of wood ash mixed with two parts of distilled water and stirred for 24 hours followed by decantation. The new technique, the Homa method, using alum and wood ash leachate was then tested on H2O samples from three areas in Kenya with high F- concentrations ranging from 5.1 mg L-1, 9.1 mg L-1 to 91.0 mg L-1. The determination of F- concentration by SPADNS Spectrophotometry was applied throughout the experiment. Four levels of alum i.e. 1%, 2%, 3%, and 4% were dosed on five volumes of water i.e. 100, 200, 300, 400, and 500 ml raw water at 5.1 and 9.1 mg L-1 F-. For water samples at 91.0 mg L-1 F-, the same volumes were treated with 5 higher alum levels i.e. 5%, 6%, 7%, 8%, and 9%. The final pH was then adjusted to 7 with ash leachate for defluoridation. The set-up was a factorial design experiment where the final F- concentration was the dependent variable and the volume of raw water, the percentages, and volume of alum and wood ash leachate constituted the different factors. A fitted multivariate regression model of the general form; where Y = Residual fluoride, X = wood Leachate volume, W = alum Concentration, X*W = Interaction α, β, γ were regression coefficients, ε = error term, showed that only in the Baringo area did we have an interaction between wood ash leachate and alum concentration significant (p < 0.05). Defluoridation occurred (p < 0.05) at as low as 10% and as high as 99%, depending on the initial F- content. Total coliform decreased from 310, 290 and 270 count/l respectively to zero. Unfortunately, high chemical and TDS (from 558 mg L-1 to more than 9,000 mg L-1) enrichment were recorded in addition to the mixed data on turbidity. The overall results show that wood ash can substitute CaO in the Nalgonda process. Further investigation is however required to make it applicable for potable water production.

Buildings are demolished, when they outlived their service life, become structurally/functionally unfit, or have been built illegally. In India, an RCC framed, 40-storied high-rise building, with a built-up area of about 75,000 sqm, built without relevant approvals along with lots of violations of building bye-laws, has been demolished. There is nothing new in this demolition process, but its effect on the environment is unavailable. A study has been conducted to understand the environmental impact of this demolition. Based on the main primary construction materials, the embodied energy of this demolished building has been computed as 7.07 GJ/sqm.The civil construction cost of the building was found to be about INR 200 Crores (USD 27 million, assuming a conversion rate of 1 USD 75 INR in the year 2022). Expected GHGs emissions corresponding to this embodied energy were estimated as 42.42 × 103 MT. Energy in the demolition of the building has been computed to be about 8.7 GJ/sqm. The situation, in which this building can be retrofitted and made compliant with local building bye-laws, has been analyzed for its environmental impact.

The theoretical concept of photonic quantum nonlocality cannot be implemented physically because of the quantum Rayleigh scattering of single photons. Physical scrutiny of landmark experiments (December 2015, M. Giustina, et al. Phys. Rev. Lett. 115, 250401, and L. K. Shalm, et al., Phys. Rev. Lett. 115, 250402) is undertaken. These articles reported that measured outcomes were fitted with quantum states possessing a dominant component of non-entangled photons, thereby contradicting their own claim of quantum nonlocality. With probabilities of photon detections lower than 0.1%, the alleged quantum nonlocality cannot be classified as a resource for developing quantum computing devices, despite recent publicity. Experimental evidence of a feasible process for quantum-strong correlations has been identified (M. Iannuzzi, et al., Phys. Lett. A, 384 (9), 126200, 2020) in terms of correlations between independent and multi-photon states evaluated as Stokes vectors on the Poincaré sphere. As single-photon sources are not needed, the design and implementation of quantum computing operations and other devices will be significantly streamlined.

Introduction: Hypoglycemia affects patient safety and glycemic control during insulin treatment of both type 1 (T1DM) and type 2 diabetes mellitus (T2DM). It is still a major clinical problem in the treatment of type 1 diabetes that impairs metabolic control. This study aimed to assess hypoglycemia and associated factors among type 1 diabetes mellitus patients attending the outpatient clinics of Debra–Tabor Comprehensive and Specialized Hospital, in 2021.Method: institutional-based cross-sectional study design was conducted among 204 selected type I DM, from June 1/2021 to August 30/2021. The study participants were selected by systematic sampling method from monthly follow-up lists and lists of registration. Data were cleaned and entered into Epi Data and then exported into SPSS version 20 for analysis. Data were presented with texts, graphs, diagrams, and tables but an analytic form of findings will be presented by text form of the odds ratio. Bivariable and multivariable binary logistic regression models were fitted to identify factors associated with hypoglycemia p – value < 0.05 was considered statistically significant and reported as a 95% confidence interval (CI).Results: A total of 204 participants participated with a response rate of 100%, and prevalence of self-reported hypoglycemia was 88.7% (95%, CI: 83.8-92.6) and the prevalence of hypoglycemia was significantly associated with occupation [AOR: 4.01 (95% CI:1.86-9.35)], higher educational status [AOR: 2.13 (95% CI:1.92-13.15)], diabetic duration < 1 [AOR: 3.80 (95% CI:1.32-9.28)], poor knowledge [AOR: 4.91 (95% CI:1.09-11.06)] and favorable attitude [AOR: 5.86 (1.10-6.07)]. The current study revealed that the knowledge, attitude, and practice of respondents were 81.9% (95%, CI, 76-86.8), 73% (95% CI, 66.7-78.9), and 91.2% (95% CI, 86.8-94.6) respectively.Conclusion and recommendation: Hypoglycemia was highly prevalent among diabetic patients treated at Debra-Tabor Comprehensive and Specialized Referral Hospital. To reduce the higher prevalence of hypoglycemia the health professionals working in the hospital had better provide appropriate patient advice about, BGL monitoring, medication adherence, self-injection as well as oral hypoglycemic agent administrations.

The background of this novel study is how to apply an empirically adjusted Passive House concept in the tropics - beyond its otherwise prevailing global standards. Even though well-insulated houses have been on the planet since people settled down in some of their first dwellings, passive in the 21st century is different. It includes strict rules for airtightness and fitting of windows along with a sophisticated concept for artificial ventilation. Fresh air reachable from outside by filtered ventilation with heat recovery describes the heart of the system - if natural outside air is not preferable, it is convenient just in seasons with thermal comfort.Hence, the purpose and aim of the study presented here is to use a less common and at the same time more cost-saving approach: It might seem that the modern type of passive house entails the same standards that have been developed firmly on its own global market niche. However, this article tries to contribute toward a new development of modern passive homes for low-cost affordable tropical and subtropical houses in their entirety.As a concluding note, the author states that nobody has ever disproven this evolving concept as a combination of airtightness and a new way of forced ventilation without heat- or coolness recovery which is highly applicable for low-cost residential areas in tropical countries. By generating lower temperatures, it can help to surpass the overheating caused by climate change in certain tropical climate zones in higher altitudes and during cooler seasons. The condition is that the occupants are willing to accept a thermal comfort of up to 28 °C and humidity in its 70s and 80s.

Wheat bran and groundnut shell powder have been used to study the mechanism of diclofenac sodium adsorption from aqueous solution using batch as well as column modes and maximum uptake is 84.3% for wheat bran and 82.4% for groundnut shell powder at pH 6, drug concentration 1mg/L at 298 K for 30min. Isotherm and error analysis reveals that Freundlich and Langmuir isotherms fitted well. Kinetic studies show that the adsorption process follows second-order kinetics and thermodynamic study shows endothermic adsorption process. Column adsorption study is important for industrial scale adsorption and column studies have been carried out using vertical bed and sequential bed adsorption columns at pH 6 which is the optimum pH for maximum adsorption for batch experiments. Vertical and sequential bed columns setup is simple and economical which provides flow under gravity. The effect of varying inlet feed concentration and flow rate on the breakthrough and exhaustion time of columns has been studied to determine the bed capacities of both columns. Thomas model and Yoon-Nelson models fitted well with experimental data for continuous flow column studies.
