AbstractObjectivesTo examine the associations between experiences of child maltreatment and mental disorders in the Australian population.DesignPopulation‐representative survey conducted by computer‐assisted telephone interviewing.Setting, participantsAustralian residents aged 16 years and older.Main outcome measuresMental disorder diagnoses of lifetime major depressive disorder, current alcohol use disorder (mild, moderate and severe), current generalised anxiety disorder and current post‐traumatic stress disorder.ResultsMore than one in three Australians (3606/8503 surveyed participants; 38.0%; 95% CI, 36.7–39.3%) met the diagnostic criteria for a mental disorder. The prevalence of mental disorders in non‐maltreated participants was 21.6% (95% CI, 19.9–23.3%; n = 851). This increased to 36.2% (95% CI, 33.5–38.9%; n = 764) for those who experienced a single type of maltreatment and 54.8% (95% CI, 52.6–56.9%; n = 1991) for participants who experienced multi‐type maltreatment. Compared with non‐maltreated Australians, maltreated participants had about three times the odds of any mental disorder (odds ratio [OR], 2.82; 95% CI, 2.47–3.22), generalised anxiety disorder (OR, 3.14; 95% CI, 2.48–3.97), major depressive disorder (OR, 3.19; 95% CI, 2.68–3.80) and severe alcohol use disorder (OR, 2.62; 95% CI, 1.83–3.76), and almost five times the odds of post‐traumatic stress disorder (OR, 4.60; 95% CI, 3.00–7.07). Associations between experiences of child maltreatment and mental disorders were strongest for sexual abuse, emotional abuse and multi‐type maltreatment. The strength of the associations did not differ by gender. Adjustment for childhood and current financial hardship and for current socio‐economic status did not significantly attenuate the associations.ConclusionsMental disorders are significantly more likely to occur in individuals who experience child maltreatment, particularly multi‐type maltreatment. Prevention of child maltreatment provides an opportunity to substantially reduce the prevalence of mental illness and improve the health of the Australian population.

Background: Healthcare-associated infections are major causes of morbidity and mortality associated with clinical, diagnostic, and therapeutic procedures in healthcare organizations. Enhancement of hand hygiene practices among healthcare workers is responsible for decreasing 30 to 50% of healthcare-associated infections. However, previous studies have indicated inadequate adherence to hand hygiene procedures in healthcare institutions. Therefore, increasing knowledge, attitude, and practices of hand hygiene among nursing students who participate in caring for patients is essential to improve the quality of care and patient safety. Objectives: This study aimed to examine knowledge, attitude, the practice of hand hygiene, and their associations among nursing students at Can Tho University of Medicine and Pharmacy. Materials and methods: A descriptive correlational study was conducted with 104 nursing students as study participants. Knowledge and attitude were examined by using a self-structured questionnaire, while practice was evaluated by observation based on the hand hygiene checklist of the Vietnamese Ministry of Health. Results: The findings showed that 44.2% and 66.3% of participants had good knowledge and positive hand hygiene attitudes, respectively. Poor adherence of 5 moments of hand hygiene and 6 steps of the hand hygiene procedure were revealed. Half of the respondents showed low to moderate compliance with the hand hygiene procedure. There were significant associations between knowledge, attitude, and hand hygiene practices among nursing students. Conclusion: among nursing students, poor knowledge, attitude, and hand hygiene practices were reported. The study findings supported previous literature and found that respondents emphasized the importance of training programs and hand hygiene monitoring in improving hand hygiene practices.

Introduction: The purpose of this study was to assess dental care professionals' drug prescription knowledge, practices, and reporting of adverse drug reactions (ADRs).
Methods: A cross-sectional exploratory study was conducted by using a face-to-face survey administered to a sample of dentists from tertiary care hospitals in Adana, Türkiye. A questionnaire consisted of six sections with closed-ended items including sociodemographic characteristics, knowledge about drugs, patient history information, counseling practices during prescribing, source of information and ADR reporting.
Results: The study included 180 dentists, with a 95.3% response rate. More than half of the dentists (50.6%) stated their level of knowledge about drug price/cost as low. Most of the dentists (50.6%;n=91) claimed that they never/rarely asked about health insurance during patient history information. Moreover, most of the participants reported that they never/rarely and sometimes counsel the patients regarding drug mechanism of action, side effects of the drug, interaction of prescribed drug with other drugs/nutrients. It was determined that the dentists learned about the drugs from Vademecum (Turkish Medication Guidebook: 70%;n=126) and the internet (55%;n=99). A higher proportion (85.5%) of the dentists indicated that they did not report ADR during their clinical practice.
Conclusion: This study showed a general improvement in dentists prescribing knowledge and practices, although they reported some lack of knowledge regarding drug cost, discussion about the possible side effect of a drug/interaction with other drugs/nutrients with patients and under-reporting of ADRs. Periodic education and training for dentists are critical to overcoming any problem related to prescribing errors and potential ADRs.

Published: April 2023

AbstractOxide semiconductors are promising semiconducting materials for next‐generation thin‐film transistors (TFTs). The role of the cations should be considered in the design of oxide semiconductors suitable for various applications. Ga has been widely used as a carrier suppressor in oxide semiconductors; however, research has recently been conducted to replace it with Al, which is cheaper and forms a stronger bond with O. Deposition using plasma‐enhanced atomic layer deposition (PEALD) is very useful for controlling the composition of the cations in an oxide semiconductor. In this study, an InAlZnO (IAZO) semiconductor was deposited using super‐cycle PEALD for the first time. Al2O3 (AO), AlZnO (AZO), and InAlO (IAO) as Al doping layers in IAZO are evaluated. Considering its electrical characteristics and stability, AZO is selected as the optimal Al doping layer. The IAZO thin film and TFT characteristics according to the Al doping method are examined through the role of the cations and H concentration. In addition, the Al concentration is controlled by adjusting the number of cycles in super‐cycle PEALD. As the Al concentration decreased, the mobility increased; however, the stability degraded significantly, which is induced by the increase in oxygen vacancies. Finally, the high‐Al IAZO system using AZO successfully showed overall excellent properties including mobility over 10 cm2 V−1 s, and outstanding stability under 0.1 V, which are greatly improved compared to previously reported IAZO TFTs.
Examining injury trends in parcel delivery drivers in the United States: Challenges and opportunities

Published: April 2023

AbstractIntroductionGrowth of e‐commerce has caused a vast increase in parcel delivery, which raises concern for safety of drivers and other road users as more deliveries take place.MethodsThis project analyzes injury/illness and fatality trends among workers with delivery‐related NAICS codes using three major sources of occupational hazard data in the United States: the Survey of Occupational Illnesses and Injuries, the Census of Fatal Occupational Injuries, and the Industrial Tracking Application. Descriptive statistics were employed to illustrate trends over time as well as to highlight opportunities for improved data collection and dissemination.ResultsThe number of injuries to drivers has risen sharply over the past decade. Some of this increase appears due to growth of this industry, but increasing overall rates suggest the industry is becoming more hazardous. While nonfatal injuries were typically caused by continuous workplace exposures (e.g., repetitive strain, contact with object/equipment), fatalities were almost exclusively caused by transportation incidents. Additionally, crucial aspects of these trends are difficult or impossible to analyze given the current data landscape.ConclusionsObserved trends reinforce earlier calls for additional scrutiny of working conditions that threaten drivers. Injuries caused by transportation incidents are likely more severe than others and highlight the danger the transportation system poses to drivers and others. Current data collection and dissemination processes offer room to improve in terms of understanding how to prevent future injuries.
