The patient safety practices of emergency medical teams in disaster zones: a systematic analysis
Introduction: Disaster zone medical relief has been criticised for poor quality care, lack of standardisation and accountability. Traditional patient safety practices of Emergency Medical Teams (EMT) in disaster zones were not well understood. Improving the quality of healthcare in disaster zones has gained importance within global health policy. Ascertaining patient safety practices of EMTs in disaster zones may identify areas of practice that can be improved. Methods: A systematic search of OvidSP, Embase and Medline databases, key journals of interest, key grey-literature texts, the databases of the World Health Organisation (WHO), Médecins Sans Frontieres (MSF) and the International Committee of the Red Cross (ICRC), and Google Scholar were performed. Descriptive studies, case reports, case series, prospective trials and opinion pieces were included with no limitation on date or language of publication. Results: There were 9,685 records, evenly distributed between the peer-reviewed and grey literature. Of these, 30 studies and 9 grey literature texts met the inclusion criteria and underwent qualitative synthesis. From these articles, 302 patient safety statements were extracted. Thematic analysis categorised these statements into 84 themes (total frequency 632). The most frequent themes were limb injury (9%), medical records (5.4%), surgery decision making (4.6%), medicines safety (4.4%) and protocol (4.4%) Conclusion: Patient safety practices of EMTs in disaster zones are weighted towards acute clinical care, particularly surgery. The management of Non-Communicable Disease (NCD) is underrepresented. There is widespread recognition of the need to improve medical record keeping. High-quality data and institutional level patient safety practices are lacking. There is no consensus on disaster zone specific performance indicators. These deficiencies represent opportunities to improve patient safety in disaster zones
Seven common errors in finding exact solutions of nonlinear differential equations
We analyze the common errors of the recent papers in which the solitary wave
solutions of nonlinear differential equations are presented. Seven common
errors are formulated and classified. These errors are illustrated by using
multiple examples of the common errors from the recent publications. We show
that many popular methods in finding of the exact solutions are equivalent each
other. We demonstrate that some authors look for the solitary wave solutions of
nonlinear ordinary differential equations and do not take into account the well
- known general solutions of these equations. We illustrate several cases when
authors present some functions for describing solutions but do not use
arbitrary constants. As this fact takes place the redundant solutions of
differential equations are found. A few examples of incorrect solutions by some
authors are presented. Several other errors in finding the exact solutions of
nonlinear differential equations are also discussed.Comment: 42 page
Fruit and vegetable intake and risk of cancer in the Swedish women’s lifestyle and health cohort
Objective To investigate whether intake of fruits and
vegetables is associated with overall cancer incidence in a
large prospective cohort of women in Sweden characterised by young age at enrolment (30–49 years) and relatively low intake of fruits and vegetables.
Methods We followed prospectively 49,261 women, who
completed a food frequency questionnaire in 1991–1992. A
total of 2,347 incident invasive cancer cases were identified
until December 2006. The occurrence of cancer was analysed by fitting Poisson regression models, estimating incidence rate ratios (RR) and 95% confidence intervals (CI).
Results The median intake of fruits and vegetables was
204 g/day (10th; 90th percentile: 37; 564 g/day). Intake of
fruits and vegetables was not statistically significantly associated with overall cancer incidence. When we compared
women in the highest quintile of fruit and vegetable intake to
women in the lowest quintile, the RR for overall cancer was
1.01 (95% CI: 0.88–1.16). Similar results were obtained when
investigating the effect of intake of fruits and vegetables
separately and when we stratified women by age at follow-up.
Conclusion Fruit and vegetable intake was not associated
with risk of total cancer in this prospective cohort of
women in Sweden
Assessing the efficacy of a brief universal family skills programme on child behaviour and family functioning in Gilgit-Baltistan, Pakistan: Protocol for a feasibility randomised controlled trial of the Strong Families programme
Purpose The global burden of mental health difficulties among children underscores the importance of early prevention. This study aims to assess the efficacy, feasibility and acceptability of the Strong Families programme in enhancing child behaviour and family functioning in low-resource settings in Gilgit-Baltistan, Pakistan. Methods and analysis This is a two-arm, multisite feasibility randomised controlled trial with an embedded process evaluation in three districts of Gilgit-Baltistan, namely Gilgit, Hunza and Skardu. 90 families living in these challenged settings, comprising a female primary caregiver aged 18 or above, and at least one child aged 8-15 years, will participate. Participants will be randomly assigned to either receive the Strong Families programme or to the waitlist group. Strong Families is a 7-hour family skills group intervention programme attended by children and their primary caregivers over 3 weeks. The waitlist group will be offered the intervention after their outcome assessment. Three raters will conduct blind assessments at baseline, 2 and 6 weeks postintervention. The primary outcome measures include the feasibility of Strong Families, as determined by families' recruitment and attendance rates, and programme completeness (mean number of sessions attended, attrition rates). The secondary outcomes include assessment of child behaviour, parenting practices, parental adjustment and child resilience. Purposefully selected participants, including up to five caregivers from each site, researchers and facilitators delivering the intervention, will be interviewed. Descriptive statistics will be used to analyse primary and secondary outcomes. The process evaluation will be conducted in terms of programme context, reach, fidelity, dose delivered and received, implementation, and recruitment. Ethics and dissemination This study has been approved by the UNODC Drug Prevention and Health Branch in the Headquarters office of Vienna and the National Bioethics Committee of Pakistan. Findings will be disseminated through publication in reputable journals, newsletters and presentations at conferences. Trial registration number NCT05933850
The status of hepatitis C virus infection among people who inject drugs in the Middle East and North Africa.
BACKGROUND AND AIMS: People who inject drugs (PWID) are a key population at high risk of hepatitis C virus (HCV) infection. The aim of this study was to delineate the epidemiology of HCV in PWID in the Middle East and North Africa (MENA). METHODS: Syntheses of data were conducted on the standardized and systematically assembled databases of the MENA HCV Epidemiology Synthesis Project, 1989-2018. Random-effects meta-analyses and meta-regressions were performed. Meta-regression variables included country, study site, year of data collection and year of publication [to assess trends in HCV antibody prevalence over time], sample size and sampling methodology. Numbers of chronically infected PWID across MENA were estimated. The Shannon Diversity Index was calculated to assess genotype diversity. RESULTS: Based on 118 HCV antibody prevalence measures, the pooled mean prevalence in PWID for all MENA was 49.3% [95% confidence interval (CI) = 44.4-54.1%]. The country-specific pooled mean ranged from 21.7% (95% CI = 4.9-38.6%) in Tunisia to 94.2% (95% CI = 90.8-96.7%) in Libya. An estimated 221 704 PWID were chronically infected, with the largest numbers found in Iran at 68 526 and in Pakistan at 46 554. There was no statistically significant evidence for a decline in HCV antibody prevalence over time. Genotype diversity was moderate (Shannon Diversity Index of 1.01 out of 1.95; 52.1%). The pooled mean percentage for each HCV genotype was highest in genotype 3 (42.7%) and in genotype 1 (35.9%). CONCLUSION: Half of people who inject drugs in the Middle East and North Africa appear to have ever been infected with hepatitis C virus, but there are large variations in antibody prevalence among countries. In addition to > 200 000 chronically infected current people who inject drugs, there is an unknown number of people who no longer inject drugs who may have acquired hepatitis C virus during past injecting drug use. Harm reduction services must be expanded, and innovative strategies need to be employed to ensure accessibility to hepatitis C virus testing and treatment
Sustainable conversion of agro-wastes into useful adsorbents
Preparation and characterization of raw andactivated carbon derived from three different selectedagricultural wastes: kola nut pod raw and activated (KNPRand KNPA), bean husk raw and activated (BHR and BHA)and coconut husk raw and activated (CHR and CHA) wereinvestigated, respectively. Influences of carbonization andacid activation on the activated carbon were investigatedusing SEM, FTIR, EDX, pHpzcand Boehm titration tech-niques, respectively. Carbonization was done at 350°C for2 h followed by activation with 0.3 M H3PO4(ortho-phosphoric acid). Results obtained from SEM, FTIR, andEDX revealed that, carbonization followed by acid acti-vation had a significant influence on morphology and ele-mental composition of the samples. SEM showed well-developed pores on the surface of the precursors after acidtreatment, FTIR spectra revealed reduction, broadening,disappearance or appearance of new peaks after acid acti-vation. EDX results showed highest percentage of carbonby atom respectively in the order BHA[KNPA[CHArespectively. The pHpzcwas found to be 5.32, 4.57 and 3.69for KNPA, BHA and CHA, respectively. Boehm titrationresult compliments that of pHpzc, indicating that the sur-faces of the prepared adsorbents are predominantly acidic.This study promotes a sustainable innovative use of agro-wastes in the production of cheap and readily availableactivated carbons, thereby ensuring more affordable waterand effluent treatment adsorbents
