Abstract
Background

Tendons have limited reparative ability. With less specialized tissue characteristics, tendon injury might be one of the most promising tissues to be successfully treated by stem cell transplantation. We performed a randomized, controlled study to investigate the effects of mesenchymal stem cell injection for treating partial tears in the supraspinatus tendon.
Methods

We enrolled 24 patients with shoulder pain lasting more than 3 months and partial tears in the supraspinatus tendon. Participants were assigned to three groups: stem cells in fibrin glue, normal saline/fibrin glue mixture, and normal saline only, with which intra-lesional injection was performed. Pain at activity and rest, shoulder function and tear size were evaluated. For safety measures, laboratory tests were taken and adverse events were recorded at every visit. Participants were followed up at 6, 12 weeks, 6, 12 months and 2 years after injection. The primary outcome measure was the improvement in pain at activity at 3 months after injection.
Results

Twenty-three patients were included in the final analysis. Primary outcome did not differ among groups (p = 0·35). A mixed effect model revealed no statistically significant interactions. Only time significantly predicted the outcome measure. All participants reported transient pain at the injection site. There were no differences in post-injection pain duration or severity. Safety measures did not differ between groups, and there were no persistent adverse events.
Conclusions

Stem cell injection into supraspinatus partial tears in patients with shoulder pain lasting more than 3 months was not more effective than control injections. (ClinicalTrials.gov Identifier: NCT02298023)

Abstract
Background: Minimally invasive mitral valve surgery has been established as a routine procedure at our institution. In the present study, early and mid-term outcomes of patients who underwent minimally invasive mitral valve replacement (MIMVR), including redo-operations and elderly patients, during the 5-year post-surgery period were analyzed to review short-term morbidity and mortality, and mid-term results.Methods: Preoperative variables, intraoperative findings, and postoperative outcomes of MIMVR patients treated from January 2014 to November 2020 and prospectively stored in a database were reviewed. Survival and freedom from cerebrovascular events were evaluated using life tables and Kaplan-Meier analysis. Results: A total of 445 patients underwent minimally invasive mitral valve surgery during the study period, of whom 55 received mitral valve replacement (MVR), including 18 cases of redo-MVR and 10 elderly (≥80 years old) patients. Mean age at the time of surgery was 70.7±11.3 years. The number of patients who underwent conversion to a sternotomy was 0, while 30-day mortality was noted in one (2%). For all MIMVR cases, 1- and 5-year survival was 90.8±3.9 % and 76.5±7.1%, respectively. Furthermore, freedom from cerebrovascular events and anticoagulation-related complications was 94.3±3.2% and 84.2±6.3% at 1 and 5 years, respectively. In univariate analysis, independent predictors of hospital mortality and prolonged hospital stay included infectious endocarditis, while previous cardiac surgery and elderly status were not significant factors.Conclusions: MIMVR can be performed safely and effectively for redo-MVR and in elderly patients with very few perioperative complications. Early and mid-term outcomes in the present cohort were acceptable.

Published: July 2021

Abstract
BACKGROUND: Gastroschisis belongs to common developmental anomalies. The aim of surgical management is to restore the integrity of the abdominal wall and to insert the bowel into the abdominal cavity with the use of the primary or staged closure technique.The objective of this paper is to analyze our 20-year experience with surgical treatment of gastroschisis with primary and staged closure, to compare the postoperative course for the said techniques as well as to identify factors influencing the course and early results of treatment.METHODS: The research materials comprise of a retrospective analysis of medical history of patients treated at the Surgery Clinic in Poznan in the years 2000-2019. 59 patients were operated on: 30 girls and 29 boys.Surgical treatment was performed with the use of primary closure in 33% of the cases, whereas the staged silo closure was performed in 67% of the cases. RESULTS: Postoperative analgosedation was used for 6 days on average after primary closures, and for 13 days on average after staged closures. Incidence frequency of generalized bacterial infection was 21% for primary closures and 37% for staged closures. Infants treated with staged closure began enteral feeding considerably later (day 22) than those treated with primary closure (day 12). CONCLUSIONS: It is not possible to indicate clearly which surgical technique is superior to the other on the basis of the results obtained. When choosing the treatment method, the patient's clinical condition, associated anomalies and the medical team's experience must be taken into consideration.

Abstract
Background: The frequency and severity of disaster occurrence and emergency situation, and the importance of disaster risk communication of relief organizations to increase the readiness of societies in the case of disaster is increasing around the world. This study aimed to identify relief organizations' strategies to improve disaster risk communication in Iran. Methods: This qualitative study was conducted with the participation of 25 managers, relief workers, and people who had experiences in response to one of the disasters. The data were collected using semi-structured interviews and analyzed using conventional content analysis.Results: The analysis of the data of this study led to the identification of 3 categories and 9 sub-categories regarding strategies of relief organizations to improve risk communication. These categories are 1) management of information and training communication (facilitation of training processes, diverse training strategies, and integrated informing), 2) management of communication barriers (trust building, managing people's demands and efforts to respect affected people), and 3) Inter-organizational communication management (coordination to meet people's demands, improve communication coordination and strengthen communication platforms)Conclusion: Relief organizations use different strategies to improve disaster risk communication, and communication barrier management is vital for improving organizations' communication with people. Developing risk communication improvement strategies can help planners and managers design and implement effective risk management programs.

Authors: Priyadarshini Sarah Grace , Alavandar Ezhilvizhi 
Published: July 2021

Background: The mediastinum is the space between the two lungs, bounded anteriorly by the sternum and posteriorly by the vertebral column. A spectrum of neoplastic and non-neoplastic lesions can arise in the mediastinum.
Methods: A total of 14 cases were retrospectively retrieved from the Histopathology department. The cases had histopathological diagnosis either in image guided, thorocoscopic, transbronchial or excision biopsies.
Results: The majority of cases (43% n=6) were of thymic origin, which included both neoplastic lesions of thymoma group and non-neoplastic lesion like thymic cysts. The thymoma group included 3 cases of thymoma B3 and 1 case of thymoma AB. The lymphoid lesions include Hodgkin lymphoma (14.3%; n=2) and non-Hodgkin lymphoma (7.1%; n=1). The mesenchymal lesions (21.4%; n=3) included lipoma, solitary fibrous tumor and schwannoma which accounts for one case each. A rare case of ectopic parathyroid adenoma (7.1%; n=1). and a case of metastatic papillary carcinoma (7.1%; n=1) were also reported.
Conclusion: The diagnosis of mediastinal mass lesions can pose difficulties due to its wide clinicopathologic spectrum to the clinician, radiologists and pathologist. A multimodal approach with histopathological examination and immunohistochemistry can help in arriving at an accurate diagnosis.

Published: July 2021

Background: Hand hygiene is the precursor to improved health standards among healthcare workers and patients seeking outpatient services. Unhygienic hands may escalate the transmission of multi-drug resistance bacteria that poses serious pathological manifestation to the vulnerable and susceptible patients. The study aims at establishing the possible pathogen and susceptibility pattern of Staphylococcus aureus carried on hands of healthcare provider and their patients.
Methods: Cross sectional study design and random sampling of patients and convenient sampling of healthcare workers was carried out between May to August 2020 at Aga Khan University hospital Nairobi satellites. The participant’s hands palm and finger tips imprints were made on Blood agar during sample collection. The antimicrobial susceptibility pattern of Staphylococcus aureus was established using Vitek-2 automated system.
Result: The study had 374 participants out of which 14% were colonized by possible pathogens. The overall Staphylococcus aureus hand carriage prevalence 6.9% (26/374) isolated from healthcare provider and patient at outpatient facility. The methicillin resistant staphylococcal in this study was 0.56% (2/374) showing resistance to both Oxacillin and Cefoxitin. Healthcare workers are prone to colonization with possible pathogens as compared to patient P-value .049. Staphylococcus aureus isolates were all resistant to penicillin.
Conclusion: Hand hygiene mitigating measures in outpatient healthcare facilities should be sustained on the counts that 14% of possible pathogens in this study were isolated. Healthcare providers at the point of care in outpatient should strictly follow the hand hygiene protocols provided by WHO to curb the transmission of possible pathogenic bacteria.

Published: July 2021

Background: Febrile illnesses such as malaria and dengue are challenging to differentiate clinically. For more than a century, the diagnostic approach is by clinical features and microscopy or manual immune-chromatographic tests. Automated cellular (WBC) indices from hematology analyzers may afford a preliminary rapid distinction. Several abnormal scattergrams during routine CBC analysis appear for the malaria and dengue.
Material and Methods: The present study is an observational, prospective study undertaken to evaluate the diagnostic utility of Sysmex XN-L series hematology analyzer as a screening tool to trigger specific testing for malaria and dengue. It includes patients suffering from either of the two febrile illnesses (malaria or dengue) at Hematology and microbiology section of Central Diagnostic Laboratory of a tertiary care centre in Central Gujarat. The sensitivity, specificity, PPV and NPV was performed for each abnormal pattern noted on scattergram for malaria and/or dengue. Interobserver variation is also taken in consideration.
Results: Malaria cases showed a significant statistical association with the presence of an extended neutrophil zone and dengue positive cases with NS1 antigen, IgG and IgM antibodies testing showed significant association with the hourglass pattern. Higher degree of agreement was noted for the hourglass pattern, doubling of neutrophil zone pattern among the observers
Conclusion: Significant statistical correlation was observed for extended neutrophil zone and malaria cases, hourglass pattern and dengue cases with a good agreement among the observers.

Abstract

Background: Assessment of disability is part of the psychiatric diagnostic process, and validated scales are needed for the assessment of functioning. The Swedish translations of the Child Sheehan Disability Scale (CSDS) for adolescents and parents (CSDS-P) have been adapted for use in psychiatric settings.

Objective: The purpose of the study was to explore the psychometric properties of the Swedish CSDS and the CSDS-P among adolescent psychiatric patients.

Method: Patients (n = 107) were assessed with the CSDS, the Strengths and Difficulties Questionnaire (SDQ adolescent), and the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime version (K-SADS-PL) diagnostic interview. Their parents participated in the interview and completed the CSDS-P and SDQ parent.

Results: Internal consistency was α =.813 for the CSDS (three items) and α =.842 for the CSDS-P (five items). For both scales, principal component analyses showed one component. The correlations between the total scores of the CSDS and CSDS-P in relation to a general K-SADS-PL symptom summation index were rs
= .332, p < .001 and rs
= .237, p = .014, respectively. Correlations with the total K-SADS function summation index were rs
< .300 for both. The correlation between the CSDS and the total difficulties score on the SDQ was rs
= .433, p < .001.

Conclusions: The Swedish translations of the CSDS and CSDS-P had similar psychometric properties to Whiteside’s CSDS and the Adult Sheehan Disability Scale. Concurrent validity and correlation between the CSDS and CSDS-P were weak.

Published: July 2021

Abstract
Floods are often caused by short-term heavy rainfall. An Integrated Flood Analysis System (IFAS) model is good at runoff simulation and a Long Short-Term Memory (LSTM) model is good at learning massive data and realizing rainfall forecast. In this paper, the applicability of the IFAS model to runoff simulation in the Tokachi River basin and the LSTM model to forecast hourly rainfall was studied, and the accuracy of flood prediction was also studied by inputting the optimal rainfall data forecasted by the LSTM model into the IFAS model. The research results show that the IFAS model can accurately simulate the runoff process in the Tokachi River basin. In the calibration period and the verification period, the Nash–Sutcliffe Efficiency coefficient (NSE) of all simulation results are above 0.75; the LSTM model can achieve forecast hourly rainfall with high precision, the NSE of best forecast results is 0.86; the IFAS model can achieve flood prediction with high precision by using the optimal rainfall data forecasted by the LSTM model, the NSE of simulation result is 0.81. The above conclusions show that it is of great significance to combine the hourly rainfall forecasted by the LSTM model with the IFAS model for flood prediction.
Rainwater harvesting (RWH): a supplement to domestic water supply in Mvog-Betsi, Yaoundé-Cameroon

Abstract
This research is aimed at assessing the possibility of using a rainwater harvesting (RWH) system to supplement domestic water supply in the Mvog-Betsi neighbourhood of Yaoundé. The research made use of a 63-year long data series on the amount of rainfall available in the study area, an analysis of rainwater quality and an estimate of the population's monthly water demand in relation to the monthly harvestable rainwater supply. Rainwater supply for the months of September, October and November is 53.05 m3 which is considerably greater than the households' water demand of 25.56 m3 during the long dry season. This led to the design of a 27 m3 ferrocement tank as minimum storage requirement. Furthermore, a rainwater quality analysis showed that all tested parameters conform to water quality standards except for microbiological quality. The rainwater needs to be disinfected before consumption as potable water. Finally, cost estimates for installing RWH systems for low ($419), medium ($549) and high standard ($668) habitations were calculated. RWH can effectively serve as a water supply supplement in the Mvog-Betsi neighbourhood.

Published: July 2021

Esse artigo apresenta os resultados de uma pesquisa feita com alunos de Pedagogia a cerca da avaliação da aprendizagem no Ensino Superior. Trata-se de pesquisa de natureza qualitativa realizada com 19 estudantes do período noturno de uma Universidade do setor privado na cidade de São Paulo. Os dados foram analisados recorrendo-se à técnica denominada análise de conteúdo proposta por Bardin (1977). Os resultados apontam que a avaliação no ensino superior ainda está voltada para aspectos quantitativos e que os erros e acertos sobrepõem à análise qualitativa e à tomada de decisão. Sugerem também que a avaliação não serve apenas para orientar os alunos, mas também os professores. Com isso, remetem à necessidade de mudanças de paradigmas no sentido de que não se deve repensar apenas o método de avaliar, mas também o processo didático e a postura docente.

Abstract:
This article presents the results of a survey done with students of Education about the evaluation of learning in higher education. This relates to a qualitative nature survey carried with 19 students in the night period of a University of the private sector in the city of Sao Paulo. The data were analyzed using to the technique called content analysis proposed by Bardin (1977). The results indicate that the assessment in higher education is still focused on quantitative aspects and that the positive and negative points are superimposed upon the qualitative analysis and decision-making. It suggests also that the evaluation not only serves to guide students, but also teachers. Therefore, they refer to the necessity of changing such paradigms in order to rethink not only the evaluating method, but the didactic process as well as the teaching position.
A categoria da mediação: contribuições para a educação escolar e para o trabalho do professor
Authors: Darcoleto Carina Alves da Silva 
Published: July 2021

O presente texto tem o objetivo de tratar a educação escolar como uma fundamental mediação entre o homem (singular) e o conhecimento produzido e acumulado pela humanidade historicamente (geral); concebendo-a na sua relação de interdependência com a totalidade da sociedade, o que será elucidado com o exame da categoria ontológica da mediação, a qual permite compreender o homem inserido no contexto da sociedade capitalista, as possibilidades e os limites que dela derivam, de modo geral, e as questões próprias à educação escolar, em particular. Para tanto, recorrer-se-á à análise das mediações apresentada por István Mészáros, em suas obras “Marx: a teoria da alienação” (1981) e “Para além do capital: rumo a uma teoria da transição” (2002), a qual fornece a chave para se pensar em uma educação escolar comprometida com a transformação social.

Abstract:
This paper aims to provide analysis of the school as a mediating key between man (singular) and the knowledge which has been historically accumulated and produced by humanity (general); designing it in its relationship of interdependence with the totality of the society. This will be clarified by examining the ontological category of mediation, which allows understanding the man inserted in the context of capitalist society, the possibilities and limits which derive from it, and the issues related to Education in particular. Thus, we will open the analysis of mediation presented by István Mészáros, in his works "Marx: the theory of alienation" (1981) and "Beyond the capital: Toward a Theory of Transition" (2002), which provides the key to understand a school committed to the social transformation.
