Two-stage lot quality assurance sampling framework for monitoring and evaluation of neglected tropical diseases, allowing for imperfect diagnostics and spatial heterogeneity
Authors: Kazienga Adama , Coffeng Luc E. , de Vlas Sake J. , Levecke Bruno 
Published: April 2022

Background
Monitoring and evaluation (M&E) is a key component of large-scale neglected tropical diseases (NTD) control programs. Diagnostic tests deployed in these M&E surveys are often imperfect, and it remains unclear how this affects the population-based program decision-making.

Methodology
We developed a 2-stage lot quality assurance sampling (LQAS) framework for decision-making that allows for both imperfect diagnostics and spatial heterogeneity of infections. We applied the framework to M&E of soil-transmitted helminth control programs as a case study. For this, we explored the impact of the diagnostic performance (sensitivity and specificity), spatial heterogeneity (intra-cluster correlation), and survey design on program decision-making around the prevalence decisions thresholds recommended by WHO (2%, 10%, 20% and 50%) and the associated total survey costs.

Principal findings
The survey design currently recommended by WHO (5 clusters and 50 subjects per cluster) may lead to incorrect program decisions around the 2% and 10% prevalence thresholds, even when perfect diagnostic tests are deployed. To reduce the risk of incorrect decisions around the 2% prevalence threshold, including more clusters (≥10) and deploying highly specific diagnostic methods (≥98%) are the most-cost saving strategies when spatial heterogeneity is moderate-to-high (intra-cluster correlation >0.017). The higher cost and lower throughput of improved diagnostic tests are compensated by lower required sample sizes, though only when the cost per test is <6.50 US$ and sample throughput is ≥3 per hour.

Conclusion/Significance
Our framework provides a means to assess and update M&E guidelines and guide product development choices for NTD. Using soil-transmitted helminths as a case study, we show that current M&E guidelines may severely fall short, particularly in low-endemic and post-control settings. Furthermore, specificity rather than sensitivity is a critical parameter to consider. When the geographical distribution of an NTD within a district is highly heterogeneous, sampling more clusters (≥10) may be required.

Published: April 2022

Introduction
Cigar products, including cigarillos, have increased in popularity in the U.S. and are disproportionately used by young adults. Cigarillo product characteristics can influence consumer perceptions and the appeal of these characteristics can vary by subgroup. The goal of this study was to examine a) product characteristics important to young adult cigarillo users and b) differences based on demographics and cigarillo and other tobacco/substance use behaviors.

Methods
In 2016, a convenience sample of 628 past-year cigarillo users rated the importance of the following cigarillo product characteristics when choosing a cigarillo to smoke tobacco: brand, tobacco filler quality, tobacco wrap quality, flavors, price, package graphic design, and number of cigars in the pack. Differences in mean importance by demographic, cigarillo use and other tobacco/substance use characteristics were analyzed using t-tests and ANOVA tests.

Results
The most important cigarillo product characteristics were price, quality of tobacco wrap, and flavors. The least important was graphic design of packaging. There were differences in importance by demographics and/or cigar and other tobacco/substance use behaviors for all product characteristics. In particular, pack size was rated as more important among current cigarillo users, users of foil pouches (2–3 cigarillos) or cardboard/paper boxes or other packaging styles, and current users of cigarettes, blunts and marijuana. Price was rated as more important among Hispanic/Latino and lower income smokers, and current cigarette and blunt smokers.

Conclusions
Findings suggest cigarillo users prioritize different product characteristics depending on their demographics or smoking behavior. Further research is needed to examine whether various cigar-related policies, such as those that ban flavors or set minimum pack sizes, could impact sub-populations of cigarillo users differently.
Risk factors associated with student distress in medical school: Associations with faculty support and availability of wellbeing resources
Authors: Langness Simone , Rajapuram Nikhil , Marshall Megan , Rahman Arifeen S. , Sammann Amanda 
Published: April 2022

Background
It is estimated that over half of medical students experience severe distress, a condition that correlates with low mental quality-of-life, suicidal ideation and serious thoughts of dropping out. While several risk factors for the development of severe distress have been identified, most focus on individual student characteristics. Currently, little is known about the impact medical schools have on student wellbeing.

Methods
Prospective, observational survey study from 2019–2020 from a national cohort of US medical students. Student wellbeing, school characteristics, and wellbeing resource availability was measured with a 30-question electronic survey. Medical student distress was defined as a Medical Student Wellbeing Index (MS-WBI) of ≥4. Risk factors for the development of severe distress were evaluated in a multivariate logistic regression model. The impact of the number of wellbeing resources available on student wellbeing was measured along multiple wellbeing domains. Independent reviewers categorized free text analysis of survey responses about desired wellbeing resources into themes.

Results
A total of 2,984 responses were included in the study, representing 45 unique medical schools. Medical school characteristics independently associated with severe distress included low faculty support (OR 4.24); the absence of mentorship resources (OR 1.63) and the absence of community building programs (OR 1.45) in a multivariate model. Increased availability of wellbeing resources was associated with lower average MS-WBI (4.58 vs. 3.19, p<0;05) and a smaller percentage of students who had taken or considered taking a leave of absence (40% vs. 16%, p<0.05). The resources most desired by students were mental health services and scheduling adjustments.

Conclusions
The majority of medical school characteristic that contribute to student distress are modifiable. Improving faculty support and offering more and varied wellbeing resources may help to mitigate medical student distress. Student feedback is insightful and should be routinely incorporated by schools to guide wellbeing strategies.

Published: April 2022

Background
In Morocco, cervical cancer is the second most common cancer affecting women behind breast cancer. The Human PapillomaVirus (HPV) vaccine has been available in Morocco since 2008 but its introduction in the national immunization program is still under discussion. There is limited data regarding acceptability and predictors of HPV vaccine acceptability among Moroccan young women. This study aimed to evaluate the awareness of female university students of HPV and the vaccine and to identify predictors of HPV vaccine acceptability.

Methods
We conducted a structured interviewer-administered questionnaire with 1087 participants in six Moroccan universities between May 2019 and June 2020.

Results
The awareness of HPV infection was 14.7% and of HPV vaccine was 7.8%. The rate of immunization coverage against HPV was less than 1%. Over 67% of participants were willing to receive the HPV vaccine. Awareness of cervical cancer (p-Value = 0.04) and the HPV vaccine (p-Value = 0.01), and acceptability of Pap smear test (p-Value <0.01) were significant predictors of HPV vaccine acceptability.

Conclusions
This study revealed an insufficient amounts of awareness of HPV and of HPV vaccine uptake in a sample of Moroccan university young women. This lack of awareness needs intervention, and it is important to develop an awareness program for young female population either within or outside universities in order to promote vaccination uptake and ultimately lower the cervical cancer rate in Morocco.
A randomized controlled trial comparing self-referred message to family-referred message promoting men’s adherence to evidence-based guidelines on BRCA1/2 germline genetic testing: A registered study protocol
Authors: Petrocchi Serena , Ongaro Giulia , Calvello Mariarosaria , Feroce Irene , Bonanni Bernardo , Pravettoni Gabriella 
Published: April 2022

Background
This is a registered study protocol on a randomized controlled trial (RCT) testing an intervention aimed to improve men’s adherence to evidence-based guidelines on BRCA1/2 germline genetic testing. BRCA1- and BRCA2-associated Hereditary Breast and Ovarian Cancer Syndrome (HBOC) increases the relative and absolute risk of developing breast and ovarian cancer and, to a lesser extent, prostate and pancreatic cancer. Men face BRCA-related cancer risks as women do, although with a different magnitude, and they may also transmit the mutations to their children. Notwithstanding, men are under-tested compared to women and the communication is not tailored on their needs. The present RCT applies principles of the Health Action Process Approach (HAPA) in testing the psychological determinants of the men’s adherence to evidence based guidelines on BRCA1/2 germline genetic and testing the efficacy of two messages.

Methods
A total of 264 participants will be involved, among the men’s relatives of women with verified germline mutations. The study entails a pre- post- evaluation with randomization of the participants in two conditions corresponding to the two messages.

Discussion
The expected results provide answers related to the impact of action self-efficacy, outcome expectancy (personal or familiar), risk perception, health risk aversion, intolerance of uncertainty, perceived barriers, and coping self-efficacy on informed decision-making. Data gathered from this study may inform health care providers, policy makers, and public health managers about the communication strategy for men and about the psychological variables influencing decision-making.

Published: April 2022

Background
Soil-transmitted helminths (STH) are one of the most common infections affecting underprivileged populations in low- and middle-income countries. Ascaris lumbricoides, Trichuris trichiura, and hookworm are the three main species that infect people. School children are the most vulnerable groups for STH infections due to their practice of walking and playing barefoot, poor personal hygiene, and environmental sanitation. However, evidence is limited in the study area. So, this study aimed to assess the current prevalence, infection intensity, and associated risk factors of STHs among school children in Tachgayint woreda, Northcentral Ethiopia.

Methods
A cross-sectional study was conducted among school children of Tachgayint woreda from February to May 2021. The study participants were chosen via systematic random sampling. Stool samples were collected from 325 children and examined using the Kato-Katz technique. The data was analyzed using SPSS version 23. Binary and multivariable logistic regression analyses were used to identify the potential associated factors for STHs. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to measure the magnitude of the association. A P-value <0.05 was considered statistically significant.

Results
The overall prevalence of STHs in this study was 36.0% (95% CI: 30.5–41.2%). Ascaris lumbricoides are the most prevalent species 89 (27.4%) followed by hookworm 14 (4.3%) and Trichuris trichiura 10 (3.1%). All of the infected school children had light-intensity of infections with the mean of eggs per gram (EPG) being 464.53. Lack of shoe wearing habit (AOR = 4.08, 95% CI: 1.29–12.88) and having untrimmed fingernail (AOR = 1.85, 95% CI: 1.06–3.22) were identified as risk factors for STH infections.

Conclusions
More than one-third of the school children were infected with at least one STH species and this indicates that STHs are still a health problem among school children in the study area. Therefore, periodic deworming, implementation of different prevention strategies, and health education programs should be regularly applied in the area.

BackgroundThis study examined whether polygenic risk scores (PRS) for lifetime cannabis and alcohol use were associated with misusing opioids, and whether sex differences existed in these relations in an urban, African-American sample.MethodsData were drawn from three cohorts of participants (N= 1,103; 45% male) who were recruited in first grade as part of a series of elementary school-based, universal preventive intervention trials conducted in a Mid-Atlantic region of the U.S. In young adulthood, participants provided a DNA sample and reported on whether they had used heroin or misused prescription opioids in their lifetime. Three substance use PRS were computed based on prior GWAS: lifetime cannabis use from Pasman et al. (2018), heavy drinking indexed via maximum number of drinks from Gelernter et al. (2019), and alcohol consumption from Kranzler et al. (2019).ResultsHigher PRS for lifetime cannabis use, greater heavy drinking, and greater alcohol consumption were associated with heightened risk for misusing opioids among the whole sample. Significant sex by PRS interactions were also observed such that higher PRS for heavy drinking and alcohol consumption were associated with a greater likelihood of opioid misuse among males, but not females.ConclusionOur findings further elucidate the genetic contributions to misusing opioids by showing that the genetics of cannabis and alcohol consumption are associated with lifetime opioid misuse among young adults, though replication of our findings is needed.
The impact of heating, ventilation, and air conditioning design features on the transmission of viruses, including the 2019 novel coronavirus: A systematic review of ultraviolet radiation

Published: April 2022

Respiratory viruses are capable of transmitting via an aerosol route. Emerging evidence suggests that SARS-CoV-2 which causes COVID-19 can be spread through airborne transmission, particularly in indoor environments with poor ventilation. Heating, ventilation, and air conditioning (HVAC) systems can play a role in mitigating airborne virus transmission. Ultraviolet germicidal irradiation (UVGI), a feature that can be incorporated into HVAC systems, can be used to impede the ability of viruses to replicate and infect a host. We conducted a systematic review of the scientific literature examining the effectiveness of HVAC design features in reducing virus transmission—here we report results for ultraviolet (UV) radiation. We followed international standards for conducting systematic reviews and developed an a priori protocol. We conducted a comprehensive search to January 2021 of published and grey literature using Ovid MEDLINE, Compendex, and Web of Science Core. Two reviewers were involved in study selection, data extraction, and risk of bias assessments. We presented study characteristics and results in evidence tables, and synthesized results across studies narratively. We identified 32 relevant studies published between 1936 and 2020. Research demonstrates that: viruses and bacteriophages are inactivated by UV radiation; increasing UV dose is associated with decreasing survival fraction of viruses and bacteriophages; increasing relative humidity is associated with decreasing susceptibility to UV radiation; UV dose and corresponding survival fraction are affected by airflow pattern, air changes per hour, and UV device location; and UV radiation is associated with decreased transmission in both animal and human studies. While UV radiation has been shown to be effective in inactivating viruses and reducing disease transmission, practical implementation of UVGI in HVAC systems needs to consider airflow patterns, air changes per hour, and UV device location. The majority of the scientific literature is comprised of experimental, laboratory-based studies. Further, a variety of viruses have been examined; however, there are few studies of coronaviruses and none to date of SARS-CoV-2. Future field studies of UVGI systems could address an existing research gap and provide important information on system performance in real-world situations, particularly in the context of the current COVID-19 pandemic. This comprehensive synthesis of the scientific evidence examining the impact of UV radiation on virus transmission can be used to guide implementation of systems to mitigate airborne spread and identify priorities for future research.

Authors: Zhang Jiali , Rong Chunling , Yan Chenyang , Chen Jie , Yang Wenjun , Yu Lingyan , Dai Haibin 
Published: April 2022

Background
Furazolidone is a synthetic nitrofuran with a broad spectrum of antimicrobial action and has been widely used in the treatment of Helicobacter pylori (H. pylori) infection. However, its safety profile has not been clarified. Moreover, the drug fever associated with its use is frequently misdiagnosed. The aim of this study was to explore the risk factors of furazolidone-associated fever to increase awareness and stimulate further research on this topic.

Methods
This was a retrospective case-control study of patients referred to a specialist clinic for furazolidone-containing quadruple regimens for H. pylori infection at a tertiary care hospital located in Eastern China between July 2018 and September 2018. We evaluated adult patients who received furazolidone treatment for Helicobacter pylori infection. The exclusion criteria were as follows: (1) patients were pregnant or breastfeeding; (2) patients received furazolidone treatment not for Helicobacter pylori infection; (3) patients had taken antibiotics or any acid suppressant or non-steroidal anti-inflammatory drug in the last 4 weeks; (4) patients had chronic hepatic, renal, or pulmonary disease. Pertinent information was retrieved from medical records and telephone follow-up. All statistical analysis was performed in SPSS version 22.0.

Results
A total of 1499 patients received furazolidone and met the overall inclusion criterion. Of these 1499 patients, 27 (1.80%) developed drug fever. The mean time between initiation of furazolidone and the onset of fever is 11.00 ± 1.84 days, and the median peak fever was 38.87 ± 0.57°C. We found no differences in age and past drug allergy between the non-fever and fever groups. Through multiple logistic regression analysis, we found two variables as independent risk factors for furazolidone-associated fever, including gender (OR, 3.16; 95% CI, 1.26–7.91; P = 0.014) and clarithromycin (OR, 4.83; 95% CI, 2.17–10.79; P<0.001).

Conclusions
This retrospective cohort study identified two risk factors for furazolidone-associated fever, which were female and clarithromycin. We also analyzed the characteristics of drug fever during anti-Helicobacter pylori therapy. However, the underlying mechanisms are uncertain and require further research.

Published: April 2022

BackgroundSchizophrenia is a severe psychiatric disorder that causes significant social and functional impairment. Currently, the diagnosis of schizophrenia is based on information gleaned from the patient’s self-report, what the clinician observes directly, and what the clinician gathers from collateral informants, but these elements are prone to subjectivity. Utilizing computer vision to measure facial expressions is a promising approach to adding more objectivity in the evaluation and diagnosis of schizophrenia.MethodWe conducted a systematic review using PubMed and Google Scholar. Relevant publications published before (including) December 2021 were identified and evaluated for inclusion. The objective was to conduct a systematic review of computer vision for facial behavior analysis in schizophrenia studies, the clinical findings, and the corresponding data processing and machine learning methods.ResultsSeventeen studies published between 2007 to 2021 were included, with an increasing trend in the number of publications over time. Only 14 articles used interviews to collect data, of which different combinations of passive to evoked, unstructured to structured interviews were used. Various types of hardware were adopted and different types of visual data were collected. Commercial, open-access, and in-house developed models were used to recognize facial behaviors, where frame-level and subject-level features were extracted. Statistical tests and evaluation metrics varied across studies. The number of subjects ranged from 2-120, with an average of 38. Overall, facial behaviors appear to have a role in estimating diagnosis of schizophrenia and psychotic symptoms. When studies were evaluated with a quality assessment checklist, most had a low reporting quality.ConclusionDespite the rapid development of computer vision techniques, there are relatively few studies that have applied this technology to schizophrenia research. There was considerable variation in the clinical paradigm and analytic techniques used. Further research is needed to identify and develop standardized practices, which will help to promote further advances in the field.
