BACKGROUND: Speed is a primary contributing factor in teenage driver crashes. Yet, there are significant methodological challenges in measuring real-world speeding behavior.
METHODS: This case study approach analyzed naturalistic driving data for six teenage drivers in a longitudinal study that spanned the learner and early independent driving stages of licensure in Maryland, United States. Trip duration, travel speed and length were recorded using global position system (GPS) data. These were merged with maps of the Maryland road system, which included posted speed limit (PSL) to determine speeding events in each recorded trip. Speeding was defined as driving at the speed of 10 mph higher than the posted speed limit and lasting longer than 6 s. Using these data, two different speeding measures were developed: (1) Trips with Speeding Episodes, and (2) Verified Speeding Time. Conclusions & Practical Applications: Across both measures, speeding behavior during independent licensure was greater than during the learner period. These measures improved on previous methodologies by using PSL information and eliminating the need for mapping software. This approach can be scaled for use in larger samples and has the potential to advance understanding about the trajectory of speeding behaviors among novice teenage drivers.

People with learning disabilities are known to experience a wide range of health inequalities and have a lower life expectancy than the general population. During the COVID-19 pandemic this extended to higher mortality rates following infection with the novel coronavirus. This case study presents an example of a positive outcome for Jade, a 21-year-old woman with learning disabilities and autism who required a long period in intensive care following COVID-19 infection. It demonstrates the impact of effective multidisciplinary collaboration involving the acute hospital learning disability liaison nurse and Jade\'s family, leading to a wide range of reasonable and achievable adjustments to her care.

Malaria is a significant public health concern in Indonesia. Muara Enim Regency is one of the districts in South Sumatra with the most important number of indigenous malaria cases in the last three years (2018-2020). Therefore, this study aimed to identify determinants of indigenous malaria in the Muara Enim Regency.
This study was designed as a case-control study. A stratified random sample in 2018, 2019, and 2020 was used at the Primary Health Centres (PHCs) areas of Tanjung Enim and Tanjung Agung. The sample included 49 cases and 49 controls. Indigenous malaria determinants were discovered using both bivariable and multivariable logistic regression models.
The multivariable logistic regression model results show that mosquito repellent reduces malaria risk by 71% (AOR = 0.29, 95% CI: 0.11-0.64). Besides, the presence of wire mesh on ventilation reduces the risk of malaria by 76% (AOR = 0.24, 95% CI: 0.10-0.57), and the distance from mosquito breeding sites near hundred meters and fewer increases the risk of malaria by 3.88 fold (AOR = 3.88; 95% CI: 1.67-8.97).
Multivariable analysis revealed distance from mosquito breeding sites as a risk factor for malaria. Besides, the study shows that using insect repellent, wire netting in ventilation, eliminating mosquito breeding sites, mosquito repellent or protective clothing, and improving house conditions were protective factors for indigenous malaria. Therefore, preventive and promotional efforts are essential as the first step toward malaria elimination at the study site, including avoiding direct contact between residents and vectors near mosquito breeding sites.

Socioeconomic determinants of risky sexual behaviors in sub-Saharan Africa are well known. The socioeconomic determinants of the sexual behaviors of university students, however, remain unclear. This case control study aimed to investigate the socioeconomic determinants of risky sexual behavior and HIV seropositivity among university students in KwaZulu-Natal (KZN), South Africa. Participants (N = 500; 375 HIV uninfected and 125 HIV infected) from four public higher educational institutions in KZN were recruited, using a non-randomized strategy. Socioeconomic status was assessed by food insecurity, access to the government loan scheme, and sharing of the bursary/loan with family. The findings of this study suggest that students reporting food insecurity were 1.87 times more likely to have multiple sexual partners; 3.18 times more likely to engage in transactional sex for money; and presented a fivefold higher risk of engaging in transactional sex for basic needs other than money. Accessing the government financing for education and sharing of the bursary/loan with family was also significantly associated with an increased risk of having an HIV seropositive status. A significant association between socioeconomic measures, risky sexual behavior, and HIV seropositivity is demonstrated in this study. Moreover, the socioeconomic risks and drivers when determining and/or developing HIV prevention interventions, including preexposure prophylaxis use, should be considered by healthcare providers based at campus health clinics.

OBJECTIVE: This study aimed to investigate the possible association between psychological disorders and risky driving behavior (RDB) in Iran.
METHODS: This case-control study conducted in Shiraz, Iran in 2021. The case group included drivers with psychological disorders and the control group included those without any disorders. The inclusion criteria for selecting patients were: active driving at the time of the study, being 18 - 65 years old, having a driving license, having a psychological disorder including depression, bipolar disorder, anxiety spectrum disorder, or psychotic disorder spectrum confirmed by a psychiatrist, and completing an informed consent form. The exclusion criterion was the existence of conditions that interfered with answering and understanding the questions. The inclusion criteria for selecting the healthy cases were: active driving at the time of the study, being 18 - 65 years old, having a driving license, lack of any past or present history of psychiatric problems, and completing an informed consent form. The data were gathered using a researcher-made checklist and Manchester driving behavior questionnaire. First, partition around medoids method was used to extract clusters of RDB. Then, backward logistic regression was applied to investigate the association between the independent variables and the clusters of RDB.
RESULTS: The sample comprised of 344 (153 with psychological disorder and 191 without confirmed psychological disorder) drivers. Backward elimination logistic regression on total data revealed that share of medical expenditure ≤ 10% of total household expenditure (OR = 3.27, 95% CI: 1.48 - 7.24), psychological disorder (OR = 3.08, 95% CI: 1.67 - 5.70), and substance abuse class (OR = 6.38, 95% CI: 3.55 - 11.48) were associated with high level of RDB.
CONCLUSIONS: Substance abuse, psychological illnesses, and share of medical costs from total household expenditure were found to be main predictors of RDB. Further investigations are necessary to explain the impact of different psychological illnesses on driving behavior.

This study aims to evaluate the perception of safety and security in informal transport in Tunisia. This research employs a questionnaire-based survey of passengers and drivers of informal transport in Tunisia. Interviews were conducted with 215 informal transport Tunisian drivers and 255 Tunisian passengers, all above 18 years of age. Analyses have been made by employing several multivariate statistical analyses. Results showed that personal attributes of informal transport drivers influence their decision to violate traffic laws and to display risky driving behaviors. It was also found that driver skills, personality, education, experience, quality of the car, and information about the road congestion are the main factors influencing safety and security in informal transport. Non-compliance with the law by informal drivers leads to aberrant habits and behaviors as well as to a driving style beyond recognized standards. Informal drivers, police and local authorities are the parties involved in the low safety and security aspects of informal transport. It can be concluded that this study underlines that improving safety and security in informal transport cannot be achieved without improving awareness of the role of traffic laws and the need for their enforcement.

During the first half of 2019, many provinces of Iran were affected by floods, which claimed the lives of 82 people. The present study aimed to investigate the behavioral, health related and demographic risk factors associated with deaths due to floods. We measured the odds ratio and investigated the contribution and significance of the factors in relation to mortality. This case-control study was conducted in the cities affected by flood in Iran. Data were collected on the flood victims using a questionnaire. Survivors, a member of the flood victim\'s family, were interviewed. In total, 77 subjects completed the survey in the case group, and 310 subjects completed the survey in the control group. The findings indicated that factors such as the age of less than 18 years, low literacy, being trapped in buildings/cars, and risky behaviors increased the risk of flood deaths. Regarding the behavioral factors, perceived/real swimming skills increased the risk of flood deaths although it may seem paradoxical. This increment is due to increased self confidence in time of flood. On the other hand, skills and abilities such as evacuation, requesting help, and escape decreased the risk of flood deaths. According to the results, the adoption of support strategies, protecting vulnerable groups, and improving the socioeconomic status of flood-prone areas could prevent and reduce the risk of flood deaths.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 reinfection prevalence is unknown. It is essential to understand reinfection symptoms and, importantly, the lived experience.
METHODS: Case study design is the best method for understanding this contemporary pandemic and rare occurrence of reinfections. A 19-year-old White Non-Hispanic woman presented with presumed severe acute respiratory syndrome coronavirus 2 reinfection 6 weeks after initially mild symptomatic infection and consistent repeat negative results. Real-time reverse-transcription polymerase chain reaction from saliva was used for detection. Twice-weekly saliva samples were collected (a) before initial infection, (b) resumed on day 10 after initial infection until reinfection was detected, and (c) resumed on day 10 post-reinfection. A 1.5-hour virtual interview was conducted, transcribed, and independently analyzed by two researchers. Four themes emerged: (1) perceived invincibility or inevitability and subsequent immunity increases risk of transmission via inconsistent preventive behaviors; (2) normalcy desires, trusted others, and implicit social pressures to not wear masks and distance increase one\'s coronavirus disease 2019 risk; (3) physical symptoms are more severe with reinfection compared with first infection; and (4) mental health sequelae (trauma and stigma) are more severe and enduring than physical health outcomes.
CONCLUSIONS: Unmasked social interactions contradicting public health recommendations were rationalized by social circle members with heavy reliance on feeling asymptomatic, lacking a positive test (testing negative or not testing), or attributing symptoms to allergies. Stigma of testing positive and consequences of not conforming to social group behaviors is overwhelming and creates pressure to take risks. This case study provides insights and lessons learned relevant for public health messaging and continued preventive behaviors.

Introduction: Perinatal asphyxia is one of the main causes of morbidity and mortality in newborns. It generates high costs, both social and economic, and presents modifiable risk factors. Objective: To determine the biological and psychosocial factors and risk behaviors associated with the development of perinatal asphyxia (Sarnat II-III) in newborns from low socioeconomic status in a tier III university hospital in the city of Cali, Colombia. Materials and Methods: With a case and control design, 216 patients were studied (54 cases/162 controls) (1 case/3 matched controls). The cases were defined as newborns with modified or severe perinatal asphyxia (Sarnat II-III) between 2012 and 2014, with gestational age ≥ 36 weeks, with neurological signs not attributable to other causes, multiorgan compromise, advanced reanimation, and presence of a sentinel event. For the analysis, conditional logistic regression models were developed to evaluate association (OR), considering that the cases and controls had been paired by the birth and gestational age variables. Results: The final model showed that, from the group of biological variables, meconium amniotic fluid was identified as a risk factor (OR 15.28, 95%CI 2.78-83.94). Induction of labor lowered the risk of perinatal asphyxia by 97% (OR 0.03, 95%CI 0.01-0.21), and monitoring of fetal heart rate was associated with lower odds by 99% (OR 0.01, 95%CI 0.00-0.31) of developing perinatal asphyxia in the newborn. Regarding social variables, the lack of social support was identified as a risk factor for the development of perinatal asphyxia (OR 6.44, 95%CI 1.16-35.66); in contrast, secondary education lowered the odds of developing perinatal asphyxia by 85% when compared with pregnant women who only had primary school education (OR 0.15, 95%CI 0.03-0.77). Conclusion: Assessment of biological and psychosocial factors and social support is important in pregnant women to determine the risk of developing perinatal asphyxia in a low-income population.

Coronavirus disease 2019 is a serious respiratory virus pandemic. Patient characteristics, knowledge of the COVID-19 disease, risk behaviour and mental state will differ between individuals. The primary aim of this study was to investigate these variables in patients visiting an emergency department in the Netherlands during the COVID-19 pandemic and to compare the \"COVID-19 suspected\" (positive and negative tested group) with the \"COVID-19 not suspected\" (control group) and to compare in the \"COVID-19 suspected\" group, the positive and negative tested patients.
Consecutive adult patients, visiting the emergency room at the Franciscus Gasthuis & Vlietland, Rotterdam, the Netherlands, were asked to fill out questionnaires on the abovementioned items on an iPad. The patients were either \"COVID-19 suspected\" (positive and negative tested group) or \"COVID-19 not suspected\" (control group).
This study included a total of 159 patients, 33 (21%) tested positive, 85 (53%) negative and 41 (26%) were COVID-19 not suspected (control group). All patients in this study were generally aware of transmission risks and virulence and adhered to the non-pharmaceutical interventions. Working as a health care professional was correlated to a higher risk of SARS-Cov-2 infection (p- value 0.04). COVID-19 suspected patients had a significantly higher level of anxiety compared to COVID-19 not suspected patients (p-value < 0.001). The higher the anxiety, the more seriously hygiene measures were followed. The anxiety scores of the patients with (pulmonary) comorbidities were significantly higher than without comorbidities.
This is one of the first (large) study that investigates and compares patient characteristics, knowledge, behaviour, illness perception, and mental state with respect to COVID-19 of patients visiting the emergency room, subdivided as being suspected of having COVID-19 (positive or negative tested) and a control group not suspected of having COVID-19. All patients in this study were generally aware of transmission risks and virulence and adhered to the non-pharmaceutical interventions. COVID-19 suspected patients and patients with (pulmonary) comorbidities were significantly more anxious. However, there is no mass hysteria regarding COVID-19. The higher the degree of fear, the more carefully hygiene measures were observed. Knowledge about the coping of the population during the COVID-19 pandemic is very important, certainly also in the perspective of a possible second outbreak of COVID-19.
