Optical radiation sources, and in particular lasers, find an ever-increasing number of applications in the medical field. It is essential that personnel who are in the presence of an optical radiation source, whether operator, patient or researcher, know precisely the risks inherent in the exposure of the human body to radiation. In order to reduce the risk of biological damage, beyond the provisions of the law on safety regulations, the precise information and accurate preparation of personnel are the main guarantee for the correct use of these sources. In all the application fields, the possibility of a biological damage cannot be completely eliminated, assuming the connotation of occupational risks. In order to understand the risks and operate their effective mitigation, the basic knowledge of the fundamental concepts at the basis of laser-matter interaction will be presented and discussed, with a focus on the physical parameters needed to efficiently estimate and mitigate the related occupational risks, in both a laboratory and clinical context.

Background: Overweight is a risk factor for non-communicable diseases and is affecting an increasing number of children worldwide. The objective of this study was to measure the prevalence and related factors to overweight among children under 5 years in five West African countries.

Methods: This study was a secondary analysis of nationally representative cross-sectional data. These data were drawn from Demographic and Health Surveys (DHS) from five countries in the West African region (Benin, Guinea, Mali, Nigeria, and Togo) from 2015 to 2018.Continuous quantitative data were categorized and all analyses were weighted according to the probability that each participant was selected in the sample. Children under 5 years of age were the study population. Multilevel logistic regression was used with Stata 16.0 software.

Results: The total sample size for the analysis was 38,657 children. The pooled prevalence of overweight among children under 5 years of age in the five countries was 3%. Guinea had the highest prevalence (6%) compared to the other countries, which had a prevalence of 2%. The likelihood of being overweight was higher among children aged 0-6 months (adjusted odds ratio [AOR] = 3.09; 95% confidence interval [CI] [2.41-3.95]), who had a high birth height (AOR = 1.64; 95% CI [1.29-2.09]), whose mothers were overweight (AOR = 1.35; 95% CI [1.09-1.68]), who lived in households with fewer than five members (AOR = 1.19; 95% CI [1.00-1.46]), or who lived in Guinea (AOR = 2.79; 95% CI [1.62-4.79]).

Conclusion: This study showed that overweight concerns few children under 5 years of age in West Africa. However, it does exist, and its prevalence could likely increase if its modifiable factors (maternal overweight, household size, and height at birth) are not taken into account in nutritional interventions.

Background: According to current estimates, there are 665,723 people in Ethiopia who have human immunodeficiency syndrome. As Ethiopia inches closer to attaining the 95/95/95 targets for treatment coverage and reaching epidemic control, however, attrition from anti-retroviral treatment is still one of the key programmatic challenges.

Objective: To assess the incidence of attrition rate and its predictors among adult HIV patients receiving anti retro viral treatment at Public Health Facility in Adea Berga/Enchini District.

Method: A 6-year (June 28, 2015 to June 27, 2021) institution-based retrospective cohort study was used to recruit 540 study participants by using simple random sampling. Data were obtained from chart review, coded, entered into Epi Data, and exported to Stata 14.2 software for analysis. At least 1 month missed appointment is considered as attrition and the predictors of attrition were identified using bivariable and multivariable Cox proportional hazard models and an adjusted hazard ratio (AHR). Bivariate and multivariate analyses were conducted to find predictors of attrition, p-value < 0.05 was considered statistically significant.

Results: From the total 540 study participant, 158 (29.26%) patients were discontinuing from follow up making the incidence rate of attrition 9.50 per 100 person years .Being WHO clinical stage III or IV (AHR = 1.96,), non-practice of Appointment spacing model (AHR = 3.98), poor or fair ART adherence level (AHR = 6.47), age groups (15-24) years (AHR = 1.73) and Others ART linkage points[index case testing, tuberculosis clinic and referral from private/public health institutions] (AHR = 1.76) were significantly associated.

Conclusions: The study showed that the incidence of attrition among adults receiving antiretroviral therapy was high. Patient sociodemographic, clinical, and treatment-related factors were significantly associated with patients on ART.

Background: Thalassemia, a congenital disorder of hemoglobin synthesis is characterized by low hemoglobin and high iron status, is prevalent in Bangladesh. Iron, consumed through drinking groundwater also increases the population iron status in Bangladesh. The study examined the effect of iron containing micronutrient powder (MNP) on the hemoglobin and ferritin status in Bangladeshi children with thalassemia and their non-thalassemia peers exposed to a high concentration of iron from drinking groundwater.

Design and methods: Three hundred twenty-seven children aged 2-5 years were recruited for an MNP efficacy trial. A sub sample (n = 222) were screened for thalassemia. Hemoglobin and ferritin levels were measured in children with and without thalassemia. Intake of iron from the key sources-diet, groundwater and MNP was measured. Mann Whitney and t-test were employed to compare the groups.

Results: Hemoglobin concentration of the children with thalassemia at the endpoint remained unchanged relative to the baseline; 11.56 ± 0.59 g/dL (Endpoint) versus 11.6 ± 0.54 g/dL (Baseline), p = 0.83. In children without thalassemia hemoglobin tended to increase; 12.54 ± 0.72 g/dL (Endpoint) versus 12.41 ± 0.72 g/dL (baseline), p = 0.06. Baseline reserve of body iron was significantly (p = 0.03) higher in thalassemia carriers (594 gm) compared to their non-carrier peers (558 gm). The increase of the infection-adjusted ferritin from baseline to the endpoint was 7.37% (p = 0.7) and 10.17% (p = 0.009) in the carrier and non-carrier groups respectively.

Conclusions: In Bangladesh, the coexistence of thalassemia and the exposure to a high concentration of iron from drinking groundwater renders anemia prevention program with a low iron MNP potentially lesser hazardous to the thalassemia carriers.

Background: The COVID-19 pandemic brought changes to primary school lunches leading to concerns over nutritional quality and uptake of lunches by vulnerable children. Regional data from Tayside, Scotland, showed that only 55% of children who were eligible for free school meals took these (normal uptake pre-pandemic was 66%). The current work aimed to identify teachers' perceptions of meal provisioning in primary schools during the first year of the COVID-19 pandemic.

Design and methods: A cross-sectional online survey was carried out among primary school teachers across Tayside, Scotland. Using an online survey (21 questions combining multiple choice formats and open text) and interviews, primary school teachers shared their views on food quality, quantity, meal choices and factors influencing uptake of primary school lunches. Interviews were recorded, transcribed and thematically analysed with respect to factors influencing consumption.

Results: The survey was completed by 41 teachers and 8 participated in a follow up interview. Around one-third (29%) of primary school teachers believed the quality of lunches had decreased and cited poor appearance of food, use of takeaway containers and food wastage. The lunch format was viewed negatively principally relating to the substitution of hot lunches with cold sandwiches, portion sizes, choice and perceived value for money. Concerns were expressed about acceptability and how far the meals contributed to food security.

Conclusions: Further work on food provisioning is needed in order to identify ways to provide a nutritional safety net for vulnerable children.

In December 2019, the current outbreak of coronavirus disease 2019 (COVID-19) was reported in Wuhan, China. Asthmatic patients are thought to be more vulnerable to the more severe form of SARS-CoV-2 infection due to their weakened immune systems and increased risk of respiratory exacerbation when infected with respiratory viruses; however, there is little evidence to support this theory. The objective of this systematic review is to assess the impact of the COVID-19 lockdown during the pandemic on asthma management outcome measures among children and adolescents. To conduct the search, we used five bibliographic databases. The results were limited to those articles published between December 2019 and February 2022, selecting only articles published in English that included the study population (children aged 0-18 years). All study designs were considered. Independent assessments of the included studies' quality were made and reported. Among the 945 results of the bibliographic search, only 21 articles were found to fit our eligibility criteria We organized the results from the studies according to the effect of the lockdown at the start of the COVID-19 pandemic on common outcomes, including the Pediatric Emergency Department Visits, hospitalization rates of pediatric asthmatic patients during the pandemic, asthma control, asthma exacerbations, psychological effects on patients, and caregivers' concerns. The management of pediatric asthma improved more during the 2020 COVID-19 pandemic lockdown than in previous years.

Background: Substance use and misuse have a negative impact on health care outcomes, specifically in the older adult population. Older adults are at risk due to several factors occurring toward the end of life such as changing family dynamics, loss of friends and loved ones, and chronic diseases. Substance use in older adults with chronic diseases in rural areas remains poorly studied. This study examines older adults greater than 55 of age in the state of Tennessee, U.S.A.

Design and methods: Data was extracted from the 2019 National Behavioral Risk Factor Surveillance System (BRFSS) with a subsample for the State of Tennessee (N = 6242) and individuals over age 55 (N = 3389).

Results: At least 33.7% (N = 1143) of older adults have a chronic disease, and 24.4% (N = 828) have at least two or more chronic diseases. Alcohol use in the past month was reported in 29.4% of older adults; however, chronic disease status was not associated with alcohol use. Marijuana use and smoking in the past month were significant for older adults with two or more chronic diseases. Low income and less high school education were associated with chronic disease and smoking.

Conclusions: Marijuana use and smoking were found to be significant in older adults with chronic disease, but not with alcohol use. Preventative measures such as screening tools, education, and providing resources to patients should be targeted to populations at risk to promote overall health outcomes.

Background: The main factor that causes a family the inability to care for patients with schizophrenia disorder is inadequate family-centered empowerment. Nevertheless, the family-integrated empowerment model has not been developed yet. This study aims to develop a integrative empowerment model to care for patients with schizophrenia disorder.

Design and methods: The mixed methods research design was divided into two stages. The first stage used a cross-sectional method with a questionnaire to 135 families who cared for patients with schizophrenia disorder using purposive sampling. Data analysis was obtained using Partial Least Squares (PLS). The second stage is a focused group discussion (FGD) conducted with six families, seven health workers, and six social workers, and discussions with two experts for model development.

Results: The integrative empowerment-based family empowerment model is developed from Outside-in empowerment (path coefficient = 0.309; t = 3.292) and Inside-out empowerment (path coefficient = 0.478; t = 4.850). Family factors is the most potent variable in shaping Inside-out empowerment (path coefficient = 0.217; t = 2.309). Moreover, re-meaning of caregiving is the strongest indicator that builds the Inside-out empowerment variable (t = 42.643). The value of Q² is 0.433 indicates that this model can be generalized, since 61% of family ability to provide care for schizophrenia patients.

Conclusions: Re-meaning of caregiving is the most potent indicator in shaping Inside-out empowerment, which is the strongest factor forming this model. Nurses assist families to be able to find activities that can generate positive meaning when caring for patients with schizophrenia disorder.

Background: Ethiopia has launched a community-based health insurance (CBHI) since 2011, which is an innovative financing mechanism to enhance domestic resource mobilization and sustainable health financing. This study assessed determinants of CBHI enrollment among HHs (households) of East Wollega, Ethiopia, 2022.

Method and materials: Community based unmatched 1:2 case-control study design was conducted between Jan 7and Feb 5/2022 among 428 HHs (144 cases and 284 controls). Cases were selected from HHs who registered for CBHI and currently using CBHI. Controls were from those who do not registered for CBHI membership. Data collected using a semi-structured, interview administered questionnaire. Multivariable logistic regression with SPSS version 25 was employed for analysis and variables were declared statistical significant association at p-value < 0.05, 95% CI.

Result: Data from 428 (144 cases and 284 controls to CBHI) were collected; a response rate of 98.8%. Statistically lower odds of CBHI enrollment was observed among HHs who have poor knowledge [AOR = 0.48 (95% CI:0.27, 0.85)], perceived not respectful care [AOR = 0.44 (95% CI :0.24, 0.81)], unavailability of laboratory services [AOR = 0.37(95% CI:0.21, 0.66)], inappropriate time of premium payment [AOR = 0.31(95% CI:0.18, 0.52)]. In addition, medium wealth status category [AOR = 0.11(95% CI: 0.03, 0.45)]. Higher odd of CBHI enrollment observed among who have formal education [AOR = 2.39(95% CI: 1.28, 4.48)].

Conclusion and recommendation: Educational level, knowledge, time of membership payment, laboratory test availability, perception of respectful care and wealth status were significant determinants of CBHI enrollment status. Hence, the responsible bodies should discuss and decide with community on the appropriate time of premium payment collection, and enhance community education on CBHI benefit package.

Background: Adult overweight and obesity, in addition to the intake of saturated fat and total serum cholesterol must be monitored as biological risk factors for non-communicable diseases (NCDs). Bioelectric impedance analysis (BIA) provides data on body fat for use in epidemiological settings. However, optimized equations should be used to calculate percentage body fat (%BF). The purpose of this study was to assess the differences between %BF calculated using different published BIA equations and %BF measured by BIA in young South African adults.

Design and methods: In this observational study, differences in calculated %BF were assessed, with different BIA equations retrieved from the literature used in 1128 healthy young adults aged 20-30 years. The %BF (measured by BIA) was compared between equations, between Black and White men and women, respectively.

Results: The results showed statistically significant differences in the %BF calculated from published BIA equations when used in young South African adults (χ² = 946, χ² = 2528, χ² = 2088, respectively, p < 0.0001). In Black and White men and women, respectively, %BF levels were significantly higher when calculated by equations, than when measured by BIA (p < 0.0001).

Conclusion: There seem to be large discrepancies in estimating %BF by BIA equations and these values cannot be used interchangeably for young South African adults. A South African age, ethnicity and sex-specific BIA equation needs to be developed to accurately estimate %BF in young South African adults.
