RESUMO

Background: The stressor vulnerability model provides theoretical support for conditions under which drinking to cope (DTC) is likely to occur (i.e., decreased adaptive coping, increased positive alcohol expectancies). However, research has only tested this model in a college sample reporting trauma. Generalizability to a non-trauma-specific sample college drinkers would support applications of the model and inferences about coping-related drinking across a broader group of young adults. Objectives: Our sample included 565 college student drinkers (Mage = 20.3 years; SDage = 2.0 years; 77.0% female; 54.2% White) from a large southeastern university. Mediation analyses examined DTC as a mediator between negative affect and alcohol-related outcomes (i.e., drinking quantity, drinking frequency, binge drinking frequency, and alcohol-related consequences). Moderated mediation models tested the influence of tension reduction expectancies and cognitive reappraisal on mediation pathways. Results: Drinking to cope was found to be a full mediator for associations between negative affect and drinking-related outcomes. For associations between negative affect and alcohol-related consequences, DTC was a partial mediator. For all alcohol outcomes, results indicated the mediation between negative affect and outcomes through DTC is strongest for individuals with greater cognitive reappraisal use. Positive alcohol expectancies did not moderate any indirect effects. Conclusions: Although cognitive reappraisal is typically considered an adaptive emotion regulation technique, our results suggest that this may not always be the case with drinking outcomes. Given our findings, further research is needed to discern the conditions wherein cognitive reappraisal may and may not be adaptive. This could be useful in informing interventions to reduce harmful DTC behaviors.

RESUMO

Objective: Simultaneous substance use is associated with worse outcomes than concurrent use. Further investigations into simultaneous use are warranted because there is limited knowledge about the co-use of substances other than alcohol and cannabis. Study aims were to examine: (1) the prevalence of simultaneous use of substances with alcohol, (2) the extent to which use patterns are related to key correlates (i.e., psychological functioning, sensation seeking), and (3) differences by college status. Methods: Participants were 623 young adult drinkers who were recruited online to complete a one-time survey. Results: Cannabis (54.3%), tobacco (53.7%), and stimulants (46.5%) were most frequently used with alcohol. Moderation analyses showed the positive association between simultaneous use and psychological distress was stronger for students whereas the positive association with sensation seeking was stronger for nonstudents. Conclusions: Results highlight the need for future research and intervention efforts that consider the link between simultaneous use and psychological wellbeing while acknowledging that educational attainment may differentially influence these factors.

RESUMO

The current study tested a mediation model of psychological functioning (i.e., perceived stressors, psychological distress, and self-regulation) and risky drinking through a drinking to cope pathway comparing college and noncollege young adults. Participants were 623 young adult drinkers (M age = 21.46) who completed an online survey. Multigroup analyses examined the proposed mediation model for college students and nonstudents. For nonstudents, the indirect effects of psychological distress to alcohol use outcomes (i.e., alcohol quantity, binge drinking frequency, and alcohol-related problems) via coping motives was significant. Further, coping motives significantly mediated the positive effects of self-regulation on alcohol quantity, binge drinking frequency, and alcohol-related problems. For students, greater psychological distress was associated with greater coping motives, which in turn, related to greater alcohol-related problems. Coping motives significantly mediated the positive effect of self-regulation on binge drinking frequency. Findings highlight the different pathways that may result in risky drinking and alcohol problems based on young adult's educational attainment. These results have important clinical implications, particularly for those who have not attended college.

RESUMO

BACKGROUND: The COVID-19 pandemic has been linked to stress, anxiety, and depression among college students, with heightened distress tied to greater drinking for some individuals. Emerging research suggests that these associations may differ across race, but few studies use adequate samples to examine this, particularly among college students, an at-risk population for both heavy drinking and mental distress. Specifically, pandemic-related stressors and mental distress may be higher among Black students than White students. The current study examined: (1) whether mental distress cross-sectionally mediates the association between pandemic-specific stressors and drinking and (2) whether race (Black or White) moderates these associations. METHODS: A cross-sectional online survey of 400 college drinkers (43% White, 28% Black) in fall 2020 assessed pandemic-related stressors (e.g., losing a job, contracting COVID-19, changed living situation), mental distress (stress, anxiety, depression), and drinking (past-month drinking, perceived changes since the start of the pandemic). RESULTS: Cross-sectional mediation models indicated that financial stressors and social distancing were linked to greater quantity and frequency of past-month drinking through greater mental distress. For perceived changes in drinking, only financial stressors were linked to drinking greater quantities and drinking more often (compared to pre-pandemic levels) via mental distress. Moderated mediation models among students identifying as White or Black revealed that changed living situation was a robust stressor across race. Financial stressors and social distancing were linked with greater distress only among White students, whereas essential worker status was a protective factor against distress only among Black students. CONCLUSIONS: Select stressors were linked to increased drinking through greater mental distress, with differential risks across Black versus White students. Findings suggest campus administrators should focus on connecting students with resources (e.g., counseling centers and health promotion offices) during times of distress.

RESUMO

OBJECTIVE: This investigation examined the impact of social networks on drinking reduction efforts following a brief alcohol intervention. In a reanalysis of data from an earlier randomized controlled trial with nonstudent emerging adult drinkers (Lau-Barraco et al., 2018), we aimed to test three domains of preintervention social network features as potential factors influencing intervention response: (a) general network characteristics (i.e., network size, network stability), (b) general network alcohol use (i.e., network alcohol abstainers, network heavy/problem drinkers), and (c) risky peers in network (i.e., proportion of drinking buddies, presence of drinking buddies identified as heavy/problem drinker). METHOD: Participants were 164 emerging adult heavy drinkers recruited from the community (65.9% men; mean age = 21.98 years; 56.2% ethnic minority). Participants were randomly assigned to either a brief personalized feedback intervention (PFI) or assessment-only control and provided data at 1-month and 3-month follow-ups. RESULTS: Greater network stability and greater representation of alcohol abstainers in one's social network were associated with improved initial postintervention response. Heavy/problem drinkers in the network did not moderate initial postintervention effects on drinking outcomes, but there was potentially a stronger intervention effect on risk reduction for those with higher proportions of drinking buddies in their network. CONCLUSIONS: Study findings provided evidence that a PFI was efficacious in mitigating some risky social network influence. However, findings did not support a consistent impact across all the network variables examined. Future research is needed to further clarify social network influences and how they may be targeted to enhance intervention efficacy. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

Sexual minority women (i.e., women who identify as lesbian, bisexual, or other non-heterosexual orientations) report more hazardous drinking compared to heterosexual women. Sexual minority stress (SMS), or experiences related to sexual orientation-based discrimination and marginalization, have been implicated as contributing to these disparities. The association between sexual minority stress and alcohol use has been supported in cross-sectional, and to a limited extent, longitudinal studies. Few studies, however, have examined associations between SMS and alcohol use in sexual minority women's daily lives. Young sexual minority women (age 18-35; N = 321) were recruited to participate in a 14-day daily diary study in which they reported each morning on their SMS and alcohol use (drinking or not; drinking quantity; alcohol consequences) from the previous day. SMS was operationalized in four ways (global negative SMS experiences, specific SMS events, concealment of identity, discrimination). Results from concurrent multilevel models revealed that on days when sexual minority women experienced more global negative SMS, any specific SMS event, or discrimination, they were more likely to drink. Further, prospective models indicated that participants drank more and were more likely to report binge drinking on the day after they experienced at least one SMS event. These findings extend prior research by demonstrating that the association between SMS and alcohol use extends to the daily level of analysis among sexual minority women. Understanding the connection between SMS and alcohol use among sexual minority women is imperative to developing culturally tailored interventions to improve the health and well-being of this at-risk group.

RESUMO

Idiopathic adulthood ductopenia (IAD) is a chronic small duct cholestatic biliary disease that is characterized by the loss of interlobular bile ducts. It is diagnosed when there is biochemical evidence of cholestatic liver disease, ductopenia on liver biopsy, and no other identifiable cause of cholestasis. We present a patient with 10 days of progressive abdominal pain, jaundice, and worsening liver function tests who advanced to fulminant liver failure with no apparent underlying cause. He was found to have cirrhosis, with biopsy demonstrative of ductopenia, consistent with idiopathic adulthood ductopenia, which is a rare etiology of cirrhosis but should be considered when the typical workup yields no answer.

RESUMO

Methylmercury is an environmental neurotoxicant found in fish that produces behavioral deficits following early developmental exposure. The impact of adolescent exposure to this developmental neurotoxicant is only recently being explored in animal models. Here, short-term memory and sustained attention were examined using a rodent model of adolescent methylmercury exposure. Rats were exposed to 0, 0.5, or 5 ppm methylmercury throughout the adolescent period and tested on a two-choice visual signal detection task in adulthood. Methylmercury improved short-term remembering in this procedure but the dose-effect curve was nonmonotonic, as has been reported previously: effects on memory were observed in animals exposed to 0.5 ppm methylmercury, but not 5 ppm. Methylmercury did not significantly alter sustained attention, which is in contrast to effects following gestational exposure in human populations. The results may suggest that attention is not involved with previously reported effects of methylmercury during adolescence, but certain procedural issues remain unresolved.

RESUMO

OBJECTIVES: Comprehensive reporting of surgical disease burden and outcomes are vital components of resilient health systems but remain under-reported. The primary objective was to identify the Victorian surgical burden of disease necessitating treatment in a hospital or day centre, including a thorough epidemiology of surgical procedures and their respective perioperative mortality rates (POMR). DESIGN: Retrospective population-level observational study. SETTING: The study was conducted in Victoria, Australia. Access to data from the Victorian Admitted Episodes Dataset was obtained using the Dr Foster Quality Investigator tool. The study included public and private facilities, including day-case facilities. PARTICIPANTS: From January 2014 to December 2016, all admissions with an International Statistical Classification of Diseases-10 code matched to the Global Health Estimates (GHE) disease categories were included. PRIMARY AND SECONDARY OUTCOME MEASURES: Admissions were assigned a primary disease category according to the 23 GHE disease categories. Surgical procedures during hospitalisations were identified using the Australian Refined Diagnosis Related Groups (AR-DRG). POMR were calculated for GHE disease categories and AR-DRG procedures. RESULTS: A total of 4 865 226 admitted episodes were identified over the 3-year period. 1 715 862 (35.3%) of these required a surgical procedure. The mortality rate for those undergoing a procedure was 0.42%, and 1.47% for those without. The top five procedures performed per GHE category were lens procedures (162 835 cases, POMR 0.001%), caesarean delivery (76 032 cases, POMR 0.01%), abortion with operating room procedure (65 451 cases, POMR 0%), hernia procedures (52 499 cases, POMR 0.05%) and other knee procedures (47 181 cases, POMR 0.004%). CONCLUSIONS: Conditions requiring surgery were responsible for 35.3% of the hospital admitted disease burden in Victoria, a rate higher than previously published from Sweden, New Zealand and the USA. POMR is comparable to other studies reporting individual procedures and conditions, but has been reported comprehensively across all GHE disease categories for the first time.

RESUMO

OBJECTIVES: Our objectives were to characterise the nature and extent of delay times to essential surgical care in a developing nation by measuring the actual stages of delay for patients receiving Bellwether procedures. SETTING: The study was conducted at Timor Leste's national referral hospital in Dili, the country's capital. PARTICIPANTS: All patients requiring a Bellwether procedure over a 2-month period were included in the study. Participants whose procedure was undertaken more than 24 hours from initial hospital presentation were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES: Data pertaining to the patient journey from onset of symptoms to emergency procedure was collected by interview of patients, their treating surgeons or anaesthetists and the medical records. Timelines were then calculated against the Three Delays Framework. RESULTS: Fifty-six patients were entered into the study. Their mean delay from symptom onset to entering the anaesthesia bay for a procedure was 32.3 hours (+/-11.6). The second delay (4.1+/-2.5 hours) was significantly less than the first (20.9+/-11.5 hours; p<0.005) and third delays (7.2+/-1.2 hours; p<0.05). Additionally, patients with acute abdominal pain (of which 18/20 ultimately had open appendicectomy and two emergency laparotomies) had a delay time of 53.3 hours (+/-21.3), significantly more than that for emergency caesarean (22.9+/-18.6 hours; p<0.05) or management of an open long-bone fracture (15.5+/-5.56 hours; p<0.05). CONCLUSIONS: Substantial delays were observed for all three stages and each Bellwether procedure. This study methodology could be used to measure access and the three delays to emergency surgical care in low/middle-income countries, although the actual reasons for delay may vary between regions and countries and would require a qualitative study.

RESUMO

In 2015, the Lancet Commission on Global Surgery (LCoGS) recommended six surgical metrics to enable countries to measure their surgical and anaesthesia care delivery. These indicators have subsequently been accepted by the World Bank for inclusion in the World Development Indicators. With support from the Royal Australasian College of Surgeons and the Pacific Islands Surgical Association, 14 South Pacific countries collaborated to collect the first four of six LCoGS indicators. Thirteen countries collected all four indicators over a 6-month period from October 2015 to April 2016. Australia and New Zealand exceeded the recommended LCoGS target for all four indicators. Only 5 of 13 countries (38%) achieved 2-hour access for at least 80% of their population, with a range of 20% (Papua New Guinea and Solomon Islands) to over 65% (Fiji and Samoa). Five of 13 (38%) countries met the target surgical volume of 5000 procedures per 100 000 population, with six performing less than 1600. Four of 14 (29%) countries had at least 20 surgical, anaesthesia and obstetric providers in their workforce per 100 000 population, with a range of 0.9 (Timor Leste) to 18.5 (Tuvalu). Perioperative mortality rate was reported by 13 of 14 countries, and ranged from 0.11% to 1.0%. We believe it is feasible to collect global surgery indicators across the South Pacific, a diverse geographical region encompassing high-income and low-income countries. Such metrics will allow direct comparison between similar nations, but more importantly provide baseline data that providers and politicians can use in advocacy national health planning.

RESUMO

BACKGROUND: The management of patients following severe trauma requires a combination of skills. Among these are accurate clinical assessment, basic resuscitation measures, basic general surgical skills and techniques, good decision making and team leadership. More technically advanced imaging and investigations are often useful and can enhance clinical assessment but should not replace the basic elements. In situations where more advanced investigations are not available good outcomes can be achieved by application of the basic principles in trauma management and surgery. This article describes a mass casualty situation of gunshot wounds managed with limited resources and the outcomes. METHODS: A series of gunshot wounds managed in a single day at Dili National Hospital, Dili, East Timor is described. The presentation of the patients, initial assessment of injuries and haemodynamic stability are detailed in addition to the subsequent surgical treatment, complications and outcomes. The information was obtained from hospital records and personal recollection of the treating doctors. All injuries were documented with digital photography. All patients were managed by two surgeons who also supervised their postoperative course and reported on their outcomes. Surgical procedures on all of the patients were performed by the named two consultant surgeons and one basic surgical trainee. RESULTS: Fourteen patients were treated for gunshot injuries. All were single bullet injuries. Six trajectories involved the thoracic or abdominal cavity (one trajectory traversed both). Eight injuries were to limbs or soft tissue of the pelvis and included four compound fractures. Surgical intervention was needed for all patients ranging from emergency laparotomy for haemodynamic instability through to wound debridements. Thirteen patients survived and were discharged from hospital within 3 weeks. One patient died of uncontrolled haemorrhage. CONCLUSIONS: In the present series of gunshot injuries managed with limited resources a good outcome was achieved with the application of basic principles. The present series emphasizes the importance of basic trauma management as outlined in courses such as Emergency Management of Severe Trauma and the use of basic surgical techniques as taught during the Advanced Surgical training program.
