Authors: Liu Yipeng , Xiao Shengyuan , Yang Yun
Published: July 2024

Given the swift expansion of the worlds population and economy, the decline in environmental quality caused by global warming, frequent climate disasters, ecosystem damage, sea level rise and other problems makes the world energy structure is changing, which means many countries start to develop their new energy industry and technology in order to meet their growing demand for energy. Therefore, promoting the energy transformation and innovation has become a new focus, and photovoltaic (PV) power generation as a green energy source is the focus of attention. PV inverters are essential components of photovoltaic array systems since they are the principal equipment capable of converting the fluctuating DC voltage produced by solar panels into mains frequency alternating current. However, the leakage current problem appeared during its operation has become one of the most important focuses of electrical engineers in recent years. This paper takes three aspects which is topology, filter and modulation mode to discuss how to suppress common mode leakage current in inverters. This paper reviews the existing research results and looks forward to their future development trends, which provides a reference for the following research.

International Experience with Glomus Tumours: An Algorithm to Improve Diagnostic Accuracy
Authors: Fenn Gary , Kennedy Sharon , Fabre Aurelie , Morrison Colin , Dolan Roisin
Published: July 2024

Background
Glomus tumours are benign tumours which most frequently affect the upper extremities, often the subungual regions of the digits. The classic triad of presenting symptoms include cold hypersensitivity, point tenderness and paroxysmal pain. The absence of a visible lesion or a lack of a complete triad of symptoms, renders these lesions notoriously difficult to diagnose. The aim of this study is to analyse the referral pathways and misdiagnosis rates in relation to management of upper limb glomus tumours at our institution and compare this to the international experience.
Methods
We conducted a retrospective review of all glomus tumours treated at our institution over a twenty year period. Medical records, radiological imaging and histopathology reports were reviewed to identify patient, disease and treatment-related factors. A literature review of published case series of upper limb glomus tumours was performed to assess referral pathways, management and misdiagnosis rates.
Results
Twenty three upper limb glomus tumours were treated at our institution between 2000 and 2022. The mean age of diagnosis was 52.56 years (27-63 years) with a male preponderance 17/23 (74%). The overall rate of misdiagnosis was 70% based upon histological request forms at the time of surgery. The lowest rates of misdiagnosis were associated with management by hand surgery specialists. Eight published case series were identified in the literature with misdiagnosis a common phenomenon. Referral to hand surgeons appears to improves diagnostic accuracy. We present an evidence-based algorithm to recommend optimal management which may guide clinicians and improve patient outcomes.

From Editor’s Desk…

Fungal diseases remain a major medical concern, posing a global hazard to human health and affecting about one billion people. The second wave of COVID-19 has hit particularly hard, drastically increasing the incidence of invasive fungal infections in countries like India. Fungal infections linked to COVID-19, primarily caused by Aspergillus and Candida species, as well as fungus belonging to the order Mucorales, have been documented in multiple countries as posing a serious threat to the healthcare system. Individuals with COVID-19 who are hospitalized are more likely to have fungal co-infections, which can worsen their prognosis by misdiagnosing the illness, which frequently leads to treatment failure and a high death rate.

Elderly, critically ill, and immunocompromised patients are more prone to opportunistic fungal diseases. Other rare but increasingly common fungal infections include those caused by Pneumocystis jirovecii, Histoplasma sp., Cryptococcus sp., and others. Fungal-related hospitalizations rose by 8.5% annually in the US between 2019 and 2021, per data that was released.

Compared to patients with non-COVID-19 associated fungal infections (12.3%), hospitalized patients with COVID-19 linked fungal infections had greater in-hospital mortality rates (48.5%). More surveillance for fungal diseases is required, especially during pandemics of respiratory viruses. Given the enormous worldwide devastation caused by the COVID-19 pandemic, it is imperative that we get more ready for infectious disease outbreaks in the future and conduct thorough public health surveillance for fungal illnesses in order to characterize disease epidemiology and direct efforts to prevent illness and death. Healthcare professionals should be more informed and ready, particularly when it comes to high-risk patients. More research, improved treatment techniques, and quicker diagnosis are required to manage these fungal infections.

Authors: Alrushud Asma
Published: July 2024

Background and Aims:
Physical inactivity and the prevalence of overweight/obesity are considered high among Saudi youth. Studying the factors that might be related to physical activity (PA) and finding strategies to promote it are necessary. This study aimed to assess the (PA) levels among medical students with different body mass index (BMI) and determine the relationship between PA and body composition.

Methods:
Eighty female students with a mean (SD) age of 20.18 (1.14) years were recruited to this comparative study. The body composition and PA levels of the participants were determined using bioelectrical impedance analysis and the International Physical Activity Questionnaire – Short Form (IPAQ-SF), respectively.

Results:
The study finds a significant but weak negative correlation between total PA score and fat % in the whole sample (P = .05, r = -.21). A Spearman’s rho test detected a moderate negative correlation between total metabolic equivalent (MET)-min/week and fat mass, as well as fat % in both the underweight and normal weight groups. Moderate positive correlations were found between total PA score and BMI, fat-free mass, and total body water in the obese group.

Conclusions:
There is a significant but weak correlation between the fat % and PA level of the female medical students who participated in this study. Variation among groups in terms of PA confirms that BMI is not an accurate predictor of a person’s PA level.

Authors: Akinwola Mary , Oladosu Monsurat , Oladimeji Olawale , Okafor Joshua , Oyeyemi Micheal , Osadolor Osaheni , Ogunleye Adelana
Published: July 2024

Stroke is a major cause of disability among older adults, and exercise is a critical component of poststroke rehabilitation. However, exercise adherence among stroke survivors is often low, leading to reduced quality of life and functional outcomes. This narrative review aims to explore the types and effectiveness of social support and technology interventions in promoting exercise adherence and improving health outcomes among older adults with stroke. The studies included in this review were relevant (original articles, systematic reviews, and meta-analyses) and reported on exercise adherence, social support, and technology within the context of older adults with stroke. The studies extracted for this narrative review were research articles published from 2010 till date. Electronic databases were searched to identify relevant studies. Our findings report that group-based exercise programs are more effective social support interventions for long-term exercise adherence than home-based individual programs for older adults. Technology, particularly remote monitoring devices and platforms, is also been effective in improving engagement and adherence to exercise programs, leading to better functional outcomes and enhanced quality of life for older adults with stroke. In conclusion, social support and technology are effective strategies for promoting exercise adherence in post-stroke older adults. However, further research is needed to identify how best to complement social support approaches with technology tools in clinical practice for optimal outcomes. Through these strategies healthcare professionals can improve functional outcomes and enhance the quality of life for stroke survivors.
Evaluation of Insulin and Glucagon-like peptide-1 Receptor Agonists Combination for Type 2 Diabetes Mellitus: An Updated Meta-analysis
Authors: Aldahash Raed , Dossari Khaled , AlAnazi Faisal , Hussein Ahmed
Published: July 2024

Glucagon-like peptide-1 receptor agonists (GLP-1RA) increase glucose-stimulated insulin secretion, suppress glucagon production, increase satiety, reduce food intake, improve insulin sensitivity, and reduce visceral fat. This study aims to compare the GLP-1RA and insulin combination or GLP-1RA added to background insulin therapy with other injectable therapies in patients with type-2 diabetes mellitus (T2DM). We searched for studies that compared GLP-1RA and insulin combination with other injectable therapies in T2DM patients for HbA1c (%) change, achieving HbA1c <7% at study end, hypoglycemia incidence, and weight change. The following intervention groups were analyzed: the combination of basal insulin and GLP-1RA, basal-plus/basal-bolus, and placebo/insulin intensification (insulin uptitration)/GLP-1RA. A total of 48 studies were included. Insulin and GLP-1RA combination therapy reduced HbA1c more than placebo/insulin intensification (insulin up-titration)/GLP-1RA (WMD -0.693, p <0.001) and basal-plus/basal-bolus (WMD -0.105, p =0.027). Insulin and GLP-1RA combination therapy significantly reduced body weight more than placebo/insulin intensification (insulin up-titration)/GLP-1RA (WMD -1.894, p <0.001) and basal-plus/basal-bolus (WMD -3.6, p =0.001). Patients on insulin and GLP-1RA combination therapy had a higher chance of achieving the HbA1c target than placebo/insulin intensification (insulin up-titration)/GLP-1RA arm (RR 1.964, p <0.001), but not than basal-plus/basal-bolus arm (RR 1.037, 95% CI 0.971 to 1.103). Hypoglycemia rates were comparable between combination therapy and placebo/insulin intensification (insulin up-titration)/GLP-1RA (RR 0.94, 95% 0.84 - 1.04), but statistically significant when compared to combination therapy and basal-plus/basal-bolus (RR 0.63, p <0.001). Our findings support using GLP-1RA in combination with insulin as a useful intensification approach for producing therapeutic improvement in T2DM therapy for individuals who have not reached their HbA1c goal.
A cross-sectional study to compare audio-visual reaction time in medical staff working on shift duty and day duty
Authors: Borkhatariya Avi , Patil Devendra
Published: July 2024

Background: Medical staff must make quick decisions and respond rapidly in modern healthcare, often working irregular hours to provide continuous care. Shift work disrupts circadian rhythms aligned with the 24-h light-dark cycle, affecting sleep quality and quantity. Adults need 7–9 h of sleep nightly, and insufficient sleep leads to slower, less precise responses and attention lapses. Reaction time, the interval between stimulus and response, is critical in medical settings and is adversely affected by sleep deprivation, resulting in daytime fatigue and reduced cognitive efficiency. This study aims to understand how shift work and day duty impact the audio-visual reaction times of medical staff. By comparing these reaction times, the research seeks to uncover how sleep patterns and circadian disruptions affect cognitive and motor skills.

Aims and Objectives: The study aims to know the effect of shift work on the audio-visual reaction time of medical staff working on shift duty to those on day duty.

Materials and Methods: The study included medical staff aged 25–40 years working in the parent institute. It is a cross-sectional study. The study consisted of 100 staff working on shift duty (study group) and 100 on day duty (control group), totaling 200 subjects. The study was carried out for 8 months. Subjects were tested for audiovisual reaction time using an audio-visual reaction time apparatus. Audio-visual reaction time was compared using an unpaired t-test.

Results: The study group consisted of 64 males and 36 females (n = 100) staff with a mean age of 31.9 ± 4.4 years while the control group consisted of 36 females and 64 males (n = 100) staff with a mean age of 33.0 ± 4.6 years. The study suggests a significant increase in the audiovisual reaction time of the study group compared to the control group with a P < 0.05.

Conclusion: The study shows a significant increase in audio-visual reaction time in medical staff working on shift duty compared to those working on day duty.

Published: July 2024

O Escore de Apgar é um método rápido de avaliação das condições clínicas do neonato, utilizado durante a assistência na sala de parto, e realizado, de forma padrão, no 1° e 5° minutos de vida. A aplicação adequada do Escore de Apgar torna-se uma ferramenta de avaliação de vitalidade neonatal com valor prognóstico importante que, apesar de isoladamente não predizer desfechos a longo prazo, de acordo com a literatura, um valor abaixo de 7 no 5º minuto de vida está fortemente relacionado a um aumento na mortalidade na primeira semana de vida do recém-nascido, devido a asfixia perinatal, assim como aumento do risco de paralisia cerebral. Contudo, o uso de baixos índices de Apgar no 5º minuto para a predição da saúde a longo prazo tem sido questionado, e os estudos apresentam resultados inconsistentes. Nesse contexto, este artigo revisa a literatura sobre como o Escore de Apgar bem aplicado pode influenciar na predição da sobrevida de neonatos reanimados na sala de parto e seu prognostico pós natal, assim como fatores de risco maternos e neonatais podem contribuir para um baixo índice deste indicador.

Getting Radical: Using Design thinking to Tackle Collaboration Issues
Authors: Bene Rose , McNeilly Elizabeth
Published: July 2024

Design Thinking (DT) has recently been adopted in some higher education disciplines as an effective pedagogical approach to enable students to acquire the skills needed for solving real world problems. As a human-centered, iterative process, design thinking is characterized by working with others to understand, define and solve problems using empathy, creativity, and radical collaboration. Many university courses also stress collaboration as a learning approach. However, not all students function well in collaborative environments. Based on their work in the Design-based Thinking course at the Werklund School of Education, University of Calgary, the authors asked, “could the design thinking process be used to foster collaboration among students and encourage radical collaboration”? In this paper the authors present a brief overview of the literature in this area and propose some parallels between the design thinking and collaborative team building processes.

The objective of the research was to evaluate the effect of educational actions in the school environment on the level of food neophobia, knowledge, consumption, acceptance, frequency of intake, planting of vegetables and assistance in cooking preparations among children. In addition, to verify the impact of actions on the sensory acceptance of food products added with vegetables with low acceptability by this public. Eighty-six children aged 7 to 10 years participated. The research was organized in three stages: pre-intervention, with filling out questionnaires and sensory analysis of the products; intervention, with application of educational actions and; post-intervention, with reapplication of questionnaires and sensory analysis of products. Actions included the implementation of vegetable gardens, theoretical-practical activities and cooking workshops. The physicochemical composition of the products was carried out to ensure food safety. Educational actions reduced the degree of food neophobia and improved the acceptability of food products by children (p < 0.05). In general, the educational actions had a positive impact (p < 0.05) on the participants’ knowledge, consumption, acceptance and frequency of vegetables intake However, there was little influence to increase the planting of vegetables at home, with no change in helping children with cooking preparations (p > 0.05). The food products presented a good nutritional profile. It is concluded that educational actions carried out at school are efficient to reduce food neophobia and increase knowledge, consumption, acceptance and frequency of intake among children. Also, they improve the acceptability of food products with the addition of vegetables with low acceptance by this public.
