The World Health Organization's Disease Outbreak News: A retrospective database.

The World Health Organization (WHO) notifies the global community about disease outbreaks through the Disease Outbreak News (DON). These online reports tell important stories about both outbreaks themselves and the high-level decision making that governs information sharing during public health emergencies. However, they have been used only minimally in global health scholarship to date. Here, we collate all 2,789 of these reports from their first use through the start of the Covid-19 pandemic (January 1996 to December 2019), and develop an annotated database of the subjective and often inconsistent information they contain. We find that these reports are dominated by a mix of persistent worldwide threats (particularly influenza and cholera) and persistent epidemics (like Ebola virus disease in Africa or MERS-CoV in the Middle East), but also document important periods in history like the anthrax bioterrorist attacks at the turn of the century, the spread of chikungunya and Zika virus to the Americas, or even recent lapses in progress towards polio elimination. We present three simple vignettes that show how researchers can use these data to answer both qualitative and quantitative questions about global outbreak dynamics and public health response. However, we also find that the retrospective value of these reports is visibly limited by inconsistent reporting (e.g., of disease names, case totals, mortality, and actions taken to curtail spread). We conclude that sharing a transparent rubric for which outbreaks are considered reportable, and adopting more standardized formats for sharing epidemiological metadata, might help make the DON more useful to researchers and policymakers.

BAAE-AgNPs Improve Symptoms of Diabetes in STZ-induced Diabetic Rats.

OBJECTIVES: Nanoparticles can be employed to improve the therapeutic activity of natural products. Type 2 diabetes mellitus is a serious health condition that has spread like a "modern pandemic" worldwide. In the present study, we developed silver nanoparticles, Ag-NPs, with an aqueous extract from Balanites aegyptiaca to investigate their antioxidant and anti-inflammatory activity in STZ-induced diabetic rats. METHODS: Aqueous extracts of Balanites aegyptiaca seeds (BAAE) were used in the synthesis of BAAE-AgNPs, which were characterized using FTIR and TEM. Different doses of BAAE-AgNP (1/50 LD50; 29.4 mg/kg b.w. and 1/20 LD50: 73.5 mg/kg b.w.) were administered to STZ-induced diabetic rats to evaluate their potential antidiabetic activity. RESULTS: FTIR spectral data indicated the presence of flavonoids and polyphenols in BAAEAgNPs. The size of the BAAE-AgNPs, determined by TEM examination, was 49.33 ± 7.59 nm, with a zeta potential of +25.37. BAAE-AgNPs were characterized by an LD50 value of 1470 mg/kg b.w. In diabetic rats, the daily oral administration of both doses of BAAE-AgNPs (29.4 and 73.5 mg/kg b.w.) for 12 weeks resulted in a significant improvement in body weight, insulin homeostasis, HbA1c, HDL-C, MDA, and pancreatic SOD, CAT, and GSH. They reduced plasma glucose, cholesterol, and triglycerides. This treatment also resulted in a significant decrease in pancreatic IL-6, p53, and TNF-α in diabetic rats. Furthermore, BAAE-AgNPs down-regulated pancreatic TGF-ß1 and Akt gene expression in diabetic rats and resulted in a significant decrease in the regulation of hepatic GLUT-2, as well as an increase in the regulation of hepatic GK and pancreatic B-cl2 gene expression. The histopathological results obtained indicated that BAAEAgNPs improved pancreatic tissue metabolism by enhancing antioxidant enzymes, suppressing inflammatory cytokines, and scavenging free radicals. CONCLUSION: The findings implied that similar to the glibenclamide-treated groups, in the BAAEAgNPs treated group, the compromised antioxidant status normalized in STZ-induced diabetes. By scavenging free radicals, BAAE-Ag-NPs protected against lipid peroxidation while reducing the risk of complications from diabetes. Compared to the daily dose of 29.4 mg, the impact was more prominent at 73.5 mg.

Evolution of liver fibrosis after interferon-based anti-hepatitis C virus therapy failure in 3,049 chronic hepatitis C patients without cirrhosis.

BACKGROUND AND STUDY AIMS: Liver fibrosis is the underlying causeof hepatitis C virus (HCV)-related disease progression to endpoints such as cirrhosis, liver failure, and hepatocellular carcinoma. The aim of our study was to assess changes in hepatic fibrosis in patients with chronic HCV who had a fibrosis evaluation at two time points at least six months apart. PATIENTS AND METHODS: This was a retrospective cohort study that included patients who had failed interferon therapy and received HCV retreatment with direct-acting antivirals (DAAs) at least six months later. Patients were evaluated previously for fibrosis according to liver biopsy and fibrosis biomarkers were evaluated before pegylated interferon and ribavirin (PEG/RBV) therapy. Fibrosis was re-evaluated with fibrosis-4 (FIB-4) scores before starting DAAs. RESULTS: A total of 3,049 patients were included [age 43.47 ± 9.07 years, 55.20 % males] and baseline histopathology showed F1, F2, and F3 in 16.86 %, 46.21 %, and 36.93 %, respectively. The mean time interval between the last dose of previously failed IFN-therapy to the first dose of DAAs was 2.38 (±1.07) years. Overall, there was a significant increase in FIB-4 scores at retreatment times (from 11.71 ± 1.13 to 22.26 ± 1.68, p < 0.001). Patients with baseline FIB-4 < 1.45 (n = 1,569) and between 1.45 and 3.25 (n = 1,237) had significant increases in their FIB-4 at the retreatment time point [median difference; 0.41 (0.91) and 0.24 (1.5), p < 0.001, respectively], whereas patients with FIB-4 > 3.25 had significant reduction of their FIB-4 score at a retreatment timepoint [-0.98 (2.93), p ≤ 0.001]. CONCLUSION: Fibrosis progressed in most patients, even within six months for some patients, and this indicates retreatment of non-system vascular resistance patients even if they do not have significant fibrosis.

Work-related injuries among 5 - 17 years-old working children in Egypt: findings from a national child labor survey.

BACKGROUND: Egypt has agreed and ratified international regulations that strict child labor. However, the country still struggles with high prevalence of child labor and the associated negative social and health effects. The objective of this study was to identify the prevalence and determinants of work-related injuries among working children in Egypt. METHODS: This study involved a secondary data analysis of the National Child Labor Survey (NCLS) conducted in 2010 by The Central Agency for Public Mobilization and Statistics (CAPMAS) in Egypt with technical and financial support from the ILO's International Program on the Elimination of Child Labor (IPEC) through its Statistical Information and Monitoring Program on Child Labor (SIMPOC). The total number of working children who responded to questions of work-related injuries in the NCLS child questionnaire was 7485 children. RESULTS: The prevalence of work-related injuries among working children in Egypt was estimated as 24.1% (95% CI: 22.0%-26.2%), of whom the majority were superficial wounds (87.3%). Among children who reported work-related injuries, 57.9% did not stop work or schooling because of the most serious injury, while 39.6% had stopped temporarily and 2.6% had stopped completely. The main determinants of work-related injuries among working children in the study sample were gender (boys), age of starting work (5-11 years), type of main economic activity (industry and services), type of main workplace (plantation, farms, or garden), the average work hours per week (28 h or more), and exposure to ergonomic and safety, and chemical hazards at work. CONCLUSIONS: The estimated high prevalence of work-related injuries among working children aged 5-17 years in Egypt raises the health risks concerns associated with child labor. Findings of this study on the determinants of work-related injuries could guide policies and interventions to combat child labor and the associated health risks, including work-related injuries.

Descriptive Epidemiology of Injuries in Professional Speedball Athletes.

CONTEXT: Speedball is an increasingly popular racquet sport played in more than 25 countries. Our objective was to describe injury incidence and patterns among Egyptian national-level speedball athletes. DESIGN: Descriptive epidemiological. METHODS: We conducted a survey of athletes who were registered with the Egyptian Speedball Federation during the 2018-2019 professional season. The survey inquired about injury types and athlete exposures (AEs). The response rate was 63% (100/160 athletes). Respondent ages ranged from 18 to 41 years. We analyzed demographic characteristics; number, location, and mechanism of injuries; treatment; and speedball participation time lost because of injury. RESULTS: Of 100 respondents, 65 reported having sustained at least one injury during the season for a total of 90 injuries and a rate of 4.7 injuries per 1000 AEs (95% confidence interval, 3.7 to 5.7). More injuries occurred during practice (77%) than during competition (23%). Thirty percent of respondents reported having missed a competition because of injury. The most frequent anatomic locations of injury were the shoulder (50%; 2.4/1000 AEs), elbow (14%; 0.68/1000 AEs), and low back (9%; 0.4/1000 AEs). The most frequently cited causes of injury were increased intensity of training (40%) and lack of warming up (18%). Seventy-seven percent of injured respondents underwent treatment by a health care professional, and 9% of these respondents underwent surgery. CONCLUSION: The shoulder was the most common anatomic location for injuries in speedball athletes. Our results suggest that attention should be directed toward sport-specific injury prevention and intervention strategies because speedball is a fast-growing sport in several countries.

Frailty and Suicidality in Older Adults: A Mini-Review and Synthesis.

The prevalence of frailty, which is significantly associated with late-life suicidality, increases with age in older adults. This review addresses the compiled evidence on the relationship between suicidality and frailty within older populations, explores the latest findings, weighs the effectiveness of various intervention strategies, and outlines potential future investigations in this area. Growing evidence suggests that identifying and addressing risk factors, including mood disorders, prior suicide attempts, poor physical health, and social isolation/problems can decrease the risk of late-in-life suicide. Various studies have shown that interventions such as diet improvements, cognitive training, psychosocial programs, and depression medication could reduce the severity of frailty and suicidality, with physical exercise being the most effective intervention. Combined programs with multiple interventions can have an even greater impact on combating depression, lowering risk of falls, and improving gait speed in older adults.

Prevalence and cost of surgical treatment for female stress urinary incontinence in Brazil: A comparison between abdominal and vaginal approaches.

OBJECTIVE: Report the progress of the treatment of female stress urinary incontinence (SUI) in Brazil through vaginal and abdominal approaches and the direct costs by hospitalisation, using DATASUS-a public entity of the Strategic and Participative Management Secretary of Health Ministry, with the responsibility of collecting, processing, and disseminating public health information. DESIGN: Epidemiological study using the Brazilian Public Health Data Center System (DATASUS). PARTICIPANTS/MATERIALS, SETTING, AND METHODS: Data were collected on all hospital admissions associated with treatment from 2008 to 2019 from the DATASUS. We analysed the records of hospitalisations associated with an abdominal or vaginal surgical SUI treatment. RESULTS: The total number of procedures for the treatment of female SUI performed from 2008 to 2019 was 84.378, of which 70 238 were vaginal and 14 140 abdominal. There was an overall decrease in the number of SUI procedures in Brazil over the years analysed (F = 52.72; P < .0001); only exception was the South region (F = 1.38; P = .267). A declining trend was identified for the abdominal approach, with an increased trend of the vaginal approach (F = 170.11; P < .0001). A declining number of hospitalisation days was noted in the vaginal procedures (P = .002). Despite the fact that no differences were noted between abdominal and vaginal expenses (P = .054), hospital expenditure increased over the years for both vaginal and abdominal approaches, with no significant differences between either approaches. However, a statistically significant professional expenditure was observed in the abdominal approach (P < .001). Analysing hospitalisation and professional expenses, the total mean in the period was statistically higher for the abdominal approach (P < .0001). CONCLUSIONS: The number of procedures to treat female SUI in Brazil has decreased from 2008 to 2019. Total financial expenditure per procedure and length of hospital stay were both higher for the abdominal approach (Burch colposuspension). A preference for a vaginal approach (pubovaginal sling or midurethral sling) has increased significantly since 2008, and our study favours this approach.
