HIV treatment-as-prevention and its effect on incidence of HIV among cisgender gay, bisexual, and other men who have sex with men in Australia: a 10-year longitudinal cohort study. Lancet HIV 2023; 10:e385-e393. [PMID: 37068498 DOI: 10.1016/s2352-3018(23)00050-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 02/04/2023] [Accepted: 02/10/2023] [Indexed: 04/19/2023]
Abstract
BACKGROUND Although HIV treatment-as-prevention reduces individual-level HIV transmission, population-level effects are unclear. We aimed to investigate whether treatment-as-prevention could achieve population-level reductions in HIV incidence among gay, bisexual, and other men who have sex with men (GBM) in Australia's most populous states, New South Wales and Victoria. METHODS TAIPAN was a longitudinal cohort study using routine health record data extracted from 69 health services that provide HIV diagnosis and care to GBM in New South Wales and Victoria, Australia. Data from Jan 1, 2010, to Dec 31, 2019, were linked within and between services and over time. TAIPAN collected data from all cisgender GBM who attended participating services, resided in New South Wales or Victoria, and were 16 years or older. Two cohorts were established: one included HIV-positive patients, and the other included HIV-negative patients. Population prevalence of viral suppression (plasma HIV viral load <200 RNA copies per μL) was calculated by combining direct measures of viral load among the HIV-positive cohort with estimates for undiagnosed GBM. The primary outcome of HIV incidence was measured directly via repeat testing in the HIV-negative cohort. Poisson regression analyses with generalised estimating equations assessed temporal associations between population prevalence of viral suppression and HIV incidence among the subsample of HIV-negative GBM with multiple instances of HIV testing. FINDINGS At baseline, the final sample (n=101 772) included 90 304 HIV-negative and 11 468 HIV-positive GBM. 59 234 patients in the HIV-negative cohort had two or more instances of HIV testing and were included in the primary analysis. Over the study period, population prevalence of viral suppression increased from 69·27% (95% CI 66·41-71·96) to 88·31% (86·37-90·35), while HIV incidence decreased from 0·64 per 100 person-years (95% CI 0·55-0·76) to 0·22 per 100 person-years (0·17-0·28). Adjusting for sociodemographic characteristics and HIV pre-exposure prophylaxis (PrEP) use, treatment-as-prevention achieved significant population-level reductions in HIV incidence among GBM: a 1% increase in population prevalence of viral suppression corresponded with a 6% decrease in HIV incidence (incidence rate ratio [IRR] 0·94, 95% CI 0·93-0·96; p<0·0001). PrEP was introduced in 2016 with 17·60% uptake among GBM that year, which increased to 36·38% in 2019. The relationship between population prevalence of viral suppression and HIV incidence was observed before the availability of PrEP (IRR 0·98, 95% CI 0·96-0·99; p<0·0001) and was even stronger after the introduction of PrEP (0·80, 0·70-0·93; p=0·0030). INTERPRETATION Our results suggest that further investment in HIV treatment, especially alongside PrEP, can improve public health by reducing HIV incidence among GBM.

Abstract
Aims To assess the management and outcomes of Placenta Accreta Spectrum disorders and highlight the important management recommendations from international guidelines. Methods A retrospective audit of women diagnosed with Placenta Accreta Spectrum disorder from January 2018 to December 2019. Results Nine cases (0.16%) of placenta accreta from 5695 births were identified. All women received caesarean section under general anaesthesia. Caesarean hysterectomy occurred in seven cases (78%). Mean (±SD) age of women was (34.4 ± 3.9 years) and mean parity score was (3.2 ± 1.2). Mean gestational age at birth was 35.1 ± 0.8 weeks. Bilateral iliac artery balloon occlusion occurred in eight (89%) cases. Median estimated blood loss [range] was 1700 mL [1000-7000] with only 11% of patients (1/9) experiencing more than 3L of blood loss. Intraoperative red blood cell transfusion occurred in six cases (67%). Median number of units of red cell transfusion [range] was four units [0-10]. Mean hospital length of stay was (6.7 ± 1.1 days) and there were no maternal deaths. Multidisciplinary team involvement of senior anaesthetists and obstetricians was noted in all cases. Discussion Placenta accreta spectrum is increasing in incidence in obstetric practice and is associated with significant maternal morbidity and mortality. Implementing national guidelines can improve patient outcomes.

Abstract
Introduction The COVID-19 pandemic caused changes to how healthcare services are utilised and delivered. Objectives We examine the impact of COVID-19 on the pattern of emergency patient presentations referred on to the community mental health team and the impact of utilising telemedicine on time to follow-up. Methods We retrospectively reviewed all clinical records of patients currently attending our service. We identified presentations to the emergency department (N=119) who were subsequently referred on for mental health follow-up. Results Patients being referred to our team from emergency departments were significantly younger during, mean age 33.1 years (SD=12.3) compared to before the pandemic, mean age 40.0 years (SD=14.5), p=0.006 and a higher proportion were new patients during, 55.8%, compared to pre-pandemic period 33.3%, p=0.015. There was also a higher proportion of patients presenting with suicidal ideation and lower proportions of affective, psychosis and suicidal/self-injurious acts during the pandemic period compared to before, p=0.006. The ratio of female to male patients on the other hand were similar during both periods, p=0.853. There appeared to be no difference in median time to follow-up pre and during the pandemic (6.0 vs 5.5 days, p=0.995). Further analysis also found no significant impact on time to follow-up upon implementing telemedicine consultations, with median days to initial follow-up of 6 days pre-pandemic, 4.5 days during pandemic + prior to telemedicine and 6.5 days during pandemic + telemedicine, p=0.602. Conclusions This study provides preliminary data on the impact of COVID-19 on mental health emergency presentations and utilization of telemedicine on time to follow-up by CMHTs. Disclosure No significant relationships.

Abstract
As the use of social media in post-secondary education expands, so does the research literature examining its effectiveness in engaging students. Studies have examined the use of Twitter as an assessment and engagement tool, and since this is a broad and growing research area, better understanding whether Twitter can promote these outcomes in an upper-level university course is valuable. This paper explores these themes based on a student survey (N=37) conducted in a Sociology Deviance course. It also reviews how students responded to the use of Twitter as a “community-classroom” engagement and assessment tool. Findings reveal that Twitter did contribute to some students’ sense of community. We offer suggestions for how instructors can successfully integrate Twitter activities into their course assessment to make them more engaging and to improve connectedness.L’utilisation des médias sociaux dans l’éducation postsecondaire prend de l’ampleur, entraînant l’augmentation de la documentation de recherche qui examine leur efficacité à motiver les élèves. Des études se sont penchées sur l’utilisation de Twitter comme outil d’évaluation et de participation. Comme il s’agit d’un domaine de recherche vaste et en croissance, il est important de mieux comprendre si Twitter peut favoriser ces résultats dans le cadre d’un cours universitaire de haut niveau. Cet article explore ces thèmes en s’appuyant sur un sondage réalisé auprès des étudiants (N=37) dans un cours de sociologie de la déviance. Il examine également comment les étudiants ont réagi à l’usage de Twitter comme outil de participation à une « classe-collectivité » et comme outil d’évaluation. Les conclusions révèlent que Twitter a contribué au sentiment d’appartenance à la collectivité de certains étudiants. Nous offrons des suggestions sur la façon dont les instructeurs peuvent intégrer avec succès des activités liées à Twitter dans leurs évaluations de cours afin de rendre ceux-ci plus motivants et d’améliorer la connectivité.

Abstract
AIM To determine whether magnetic resonance imaging (MRI) signs of subscapularis (SBT), supraspinatus (SST), or superior labral tearing predict long head of biceps (LHB) tendon tearing at arthroscopy. MATERIALS AND METHODS Subjects with MRI studies followed by arthroscopy were collected. Radiologists graded rotator cuff (RC) tendons and the superior labrum using three grade classifications and blinded to arthroscopy. Correlation between imaging variables and surgical outcome was expressed in terms of odds ratios and determined using a stepwise logistic regression model. RESULTS Selection criteria identified 89 participants. Statistically significant increase in odds of finding a partial LHB tendon tear at arthroscopy were noted for both MRI readers with any SBT tear (OR=4.1-5.6, p<0.0001 to 0.002), full-thickness SST (OR=8-20.4, p=0.002 to 0.006), and combined SST-SBT tears (OR=5.1-7.6, p<0.0001 to 0.002) and relative to grade 0 MRI scores for those categories. Statistically significant increase in the odds of finding any LHB tendon tear at arthroscopy were noted for both MRI readers with any SBT tear (OR=9.6 to 14.6, p<0.0001), full-thickness SST (OR=9.0 to 52.0, p<0.0001 to 0.0004) and combined SST-SBT tears (OR=8.2 to 15.1, p<0.0001) at MRI and relative to grade 0 MRI scores for these categories. No significant predictive effect was found for the labral categories. CONCLUSION LHB tendons should be closely scrutinised if anterosuperior rotator cuff tears, and SBT tears in particular, are found on MRI.

Abstract
BACKGROUND Cancer caregiving has emerged as a dominant focus of research in recent years. A striking feature of this vast amount of literature is that it is static, examining certain points of the cancer trajectory, mostly the diagnosis and palliative care. Only The Cancer Caregiving Experience Model conceptualised the caregiving experience and explored the conceptual implications of cancer family caregiving research. AIM The data from this paper aim to empirically support the Cancer Caregiving Experience model, by exploring the cancer caregiving experience longitudinally. METHODS Semi-structured interviews with 53 caregivers were carried out at patient's diagnosis (T1), 3 months (T2), 6 months (T3) and 12 months (T4) post diagnosis. RESULTS Analysis of 139 interviews generated four themes that reflected a complex and dynamic process. The themes that mapped those of the model were "Primary stressors", "Secondary stressors", "Appraisal", "Cognitive-Behavioural responses" and "Health and Well Being". CONCLUSIONS The study adds empirical support to The Cancer Caregiving Experience Model and confirms that different primary and secondary stressors influence how the caregivers perceive the caregiving demands, the coping mechanisms they employ and their health and well being during the cancer trajectory. Access to support services should be offered to all the caregivers from as early as the diagnosis period and take into account their specific needs.

Abstract
CONTEXT Estimates of DSM-IV disorder prevalence are high; stringent criteria to define need for services are desired. OBJECTIVE To present US national data on the prevalence and sociodemographic correlates of 12-month serious emotional disturbance (SED), defined by the US Substance Abuse and Mental Health Services Administration, from the National Comorbidity Survey Replication Adolescent Supplement. DESIGN The National Comorbidity Survey Replication Adolescent Supplement is a national survey of DSM-IV anxiety, mood, behavior, and substance disorders among US adolescents. SETTING Dual-frame household and school samples of US adolescents. PARTICIPANTS Total of 6483 pairs of adolescents aged 13 to 17 (interviews) and parents (questionnaires). MAIN OUTCOME MEASURES The DSM-IV disorders were assessed with the World Health Organization Composite International Diagnostic Interview and validated with blinded clinical interviews based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children. Serious emotional disturbance was operationalized as a DSM-IV/Composite International Diagnostic Interview disorder with a score of 50 or less on the Children's Global Assessment Scale (ie, moderate impairment in most areas of functioning or severe impairment in at least 1 area). Concordance of Composite International Diagnostic Interview SED diagnoses with blinded Schedule for Affective Disorders and Schizophrenia for School-Age Children diagnoses was good. RESULTS The estimated prevalence of SED was 8.0%. Most SEDs were due to behavior (54.5%) or mood (31.4%) disorders. Although respondents with 3 or more disorders made up only 29.0% of those with 12-month DSM-IV/Composite International Diagnostic Interview disorders, they constituted 63.5% of SEDs. Predictive effects of high comorbidity were significantly greater than the product of their disorder-specific odds ratios and consistent across disorder types. Associations of sociodemographic variables with SED were generally nonsignificant after controlling for disorder type and number. CONCLUSIONS The high estimated 12-month prevalence of DSM-IV disorders among US adolescents is largely due to mild cases. The significant between-disorder differences in risk of SED and the significant effect of high comorbidity have important public health implications for targeting interventions.

Abstract
Many publications have highlighted a lack of practical competencies in recently qualified interns. Consultation between the University of Queensland and the Medical Education Unit at Redcliffe Hospital identified key areas where intervention could lead to greater work readiness, and the development of a complementary programme of practical workshops to remedy those deficiencies. A variety of content experts introduced the Graduate Medical Course 3 and 4 students to a range of practical skills during a dedicated lunch time one hour workshop each week over a period of 30 weeks. Several sessions were audited by the trainers though the majority of sessions used self-evaluation by the participants. There was an overall self-reported increase in the ability to perform the tasks from 25% before the session to 90% afterwards. Seven of the participants are returning to the hospital as interns, and a follow-up survey will be performed to judge the usefulness of the programme.

Abstract
BACKGROUND The atopic march is well documented, but the interrelationship of food allergy (FA) and asthma is not well understood. OBJECTIVE The aim of this study was to examine the strength of the association and temporal relationships between FA and asthma. METHODS This analysis included 271 children >or=6 years (older group) and 296 children <6 years (younger group) from a family-based FA cohort in Chicago, IL. Asthma was determined by parental report of physician diagnosis. FA status was determined based on the type and timing of clinical symptoms after ingestion of a specific food, and results of prick skin test (Multi-Test II) and allergen-specific IgE (Phadia ImmunoCAP). Analyses were carried out using logistic regression accounting for important covariates and auto-correlations among siblings. Kaplan-Meier curves were used to compare the time to onset of asthma with the FA status. RESULTS Symptomatic FA was associated with asthma in both older [odds ratio (OR)=4.9, 95% confidence interval (CI): 2.5-9.5] and younger children (OR=5.3, 95% CI: 1.7-16.2). The association was stronger among children with multiple or severe food allergies, especially in older children. Children with FA developed asthma earlier and at higher prevalence than children without FA (Cox proportional hazard ratio=3.7, 95% CI: 2.2-6.3 for children >or=6 years, and hazard ratio=3.3, 95% CI: 1.1-10 for children <6 years of age). No associations were seen between asymptomatic food sensitization and asthma. CONCLUSIONS Independent of markers of atopy such as aeroallergen sensitization and family history of asthma, there was a significant association between FA and asthma. This association was even stronger in subjects with multiple food allergies or severe FA.

Abstract
BACKGROUND The increasing prevalence of food allergy (FA) is a growing clinical and public health problem. The contribution of genetic factors to FA remains largely unknown. OBJECTIVE This study examined the pattern of familial aggregation and the degree to which genetic factors contribute to FA and sensitization to food allergens. METHODS This study included 581 nuclear families (2,004 subjects) as part of an ongoing FA study in Chicago, IL, USA. FA was defined by a set of criteria including timing, clinical symptoms obtained via standardized questionnaire interview and corroborative specific IgE cut-offs for > or =95% positive predictive value (PPV) for food allergens measured by Phadia ImmunoCAP. Familial aggregation of FA as well as sensitization to food allergens was examined using generalized estimating equation (GEE) models, with adjustment for important covariates including age, gender, ethnicity and birth order. Heritability was estimated for food-specific IgE measurements. RESULTS FA in the index child was a significant and independent predictor of FA in other siblings (OR=2.6, 95% CI: 1.2-5.6, P=0.01). There were significant and positive associations among family members (father-offspring, mother-offspring, index-other siblings) for total IgE and specific IgE to all the nine major food allergens tested in this sample (sesame, peanut, wheat, milk, egg white, soy, walnut, shrimp and cod fish). The estimated heritability of food-specific IgE ranged from 0.15 to 0.35 and was statistically significant for all the nine tested food allergens. CONCLUSION This family-based study demonstrates strong familial aggregation of FA and sensitization to food allergens, especially, among siblings. The heritability estimates indicate that food-specific IgE is likely influenced by both genetic and environmental factors. Together, this study provides strong evidence that both host genetic susceptibility and environmental factors determine the complex trait of IgE-mediated FA.

Abstract
OBJECTIVE To examine college adjustment in students reporting an ADHD diagnosis and the effect of medication treatment on students' adjustment. METHOD 1,648 first-semester freshmen attending a public and a private university completed a Web-based survey to examine their adjustment to college. RESULTS Compared with 200 randomly selected control students, 68 students with ADHD reported more academic concerns and depressive symptoms. This was explained by higher rates of inattentive symptoms among students with ADHD and was unrelated to hyperactive-impulsive symptoms. Among students with ADHD, medication treatment was not related to better adjustment or diminished ADHD symptoms. The contribution of inattention to academic concerns and depressive symptoms remained significant when controlling for personality traits. CONCLUSION Students with ADHD experience greater academic performance concerns and depressive symptoms during the transition to college. Medication treatment did not appear to diminish ADHD symptoms nor enhance students' adjustment.

Abstract
Cancer survivorship has become a major issue due to people living longer with the effects of cancer treatment. A key issue in this area are the 'iatrogenic effects' of cancer treatments and their adverse impact on the quality of long-term patient survival. This paper considers the late physical effects of treatment for cervical cancer, in particular psychosocial problems associated with sexuality. The aim of this paper was to explore women's sexuality following treatment for cervical cancer. A qualitative phenomenological design was used to explore the lived experiences of a purposive sample of 13 women 2-3 years after treatment, using in-depth interviewing. The findings demonstrate that cancer treatment can result in a number of late physical effects, including bladder and bowel dysfunction. Moreover, the physical problems led to sexual difficulties experienced several years after treatment. Concerns were expressed by patients about perceived psychosexual difficulties encountered as a result of treatment. In conclusion, the study raises issues associated with the management of late treatment effects and its impact on sexuality. The findings underline the need for effective communication of possible iatrogenic effects of treatment during follow-up care and a need for research to consider the advice and information that women require about long-term treatment effects.

Abstract
BACKGROUND The objective of this study was to determine the intracranial, cardiovascular and respiratory changes induced by conversion to high-frequency oscillator ventilation from conventional mechanical ventilation at increasing airway pressures. METHODS In this study, 11 anaesthetized sheep had invasive cardiovascular and intracranial monitors placed. Lung injury was induced by saline lavage and head injury was induced by inflation of an intracranial balloon catheter. All animals were sequentially converted from conventional mechanical ventilation to high-frequency oscillator ventilation at target mean airway pressures of 16, 22, 28, 34 and 40 cm H(2)O. The mean airway pressure was achieved by adjusting positive end expiratory pressure while on conventional mechanical ventilation, and continuous distending pressures while on high-frequency oscillator ventilation. Cerebral lactate production, oxygen consumption and venous oximetry were measured and analysed in relation to changes in transcranial Doppler flow velocity. Transcranial Doppler profiles together with other physiological parameters were measured at each airway pressure. RESULTS Cerebral perfusion pressure was significantly lower during high-frequency oscillator ventilation than during conventional mechanical ventilation (CMV: 45, 34, 22, 6, 9 mmHg vs. HFOV: 33, 20, 19, 5, 5 mmHg at airway pressures mentioned above, P = 0.02). Intracranial pressure and cerebrovascular resistance increased with increasing intrathoracic pressures (P = 0.001). Cerebral metabolic indices demonstrated an initial increase in anaerobic metabolism followed by a decrease in cerebral oxygen consumption progressing to cerebral infarction as intrathoracic pressures were further increased in a stepwise fashion. Arterial PaCO(2) increased significantly after converting from conventional mechanical ventilation to high-frequency oscillator ventilation (P = 0.001). However, no difference was observed between conventional mechanical ventilation and high-frequency oscillator ventilation when intracranial pressure, metabolic and transcranial Doppler indices were compared at equivalent mean airway pressures. CONCLUSIONS The use of high positive end expiratory pressure with conventional mechanical ventilation or high continuous distending pressure with high-frequency oscillator ventilation increased intracranial pressure and adversely affected cerebral metabolic indices in this ovine model. Transcranial Doppler is a useful adjunct to intracranial pressure and intracranial venous saturation monitoring when major changes in ventilation strategy are adopted.

Abstract
Direct laryngoscopic tracheal intubation is a potentially lifesaving manoeuvre, but it is a difficult skill to acquire and to maintain. These difficulties are exacerbated if the opportunities to utilise this skill are infrequent, and by the fact that the consequences of poorly performed intubation attempts may be severe. Novice users find the Airtraq laryngoscope easier to use than the conventional Macintosh laryngoscope. We therefore wished to determine whether novice users would have greater retention of intubation skills with the Airtraq rather than the Macintosh laryngoscope. Twenty medical students who had no prior airway management experience participated in this study. Following brief didactic instruction, each took turns performing laryngoscopy and intubation using the Macintosh and Airtraq devices in easy and simulated difficult laryngoscopy scenarios. The degree of success with each device, the time taken to perform intubation and the assistance required, and the potential for complications were then assessed. Six months later, the assessment process was repeated. No didactic instruction or practice attempts were provided on this latter occasion. Tracheal intubation skills declined markedly with both devices. However, the Airtraq continued to provide better intubating conditions, resulting in greater success of intubation, with fewer optimisation manoeuvres required, and reduced potential for dental trauma, particularly in the difficult laryngoscopy scenarios. The substantial decline in direct laryngoscopy skills over time emphasise the need for continued reinforcement of this complex skill.

Abstract
The transfer of critically ill patients between hospitals carries significant risk. The Mobile Intensive Care Ambulance Service (MICAS) in Ireland was established in 1996 to provide a ground transfer service between hospitals for critically ill patients. The aim of this audit was to determine if a centralised retrieval system for interhospital transport of critically ill patients in Ireland by MICAS is safe and efficient. 484 critically ill patients transported by MICAS between April 1996 and December 2004 were studied retrospectively. There were no patient deaths during transfer. 47% of transfers were between hospitals in the greater Dublin area. 45% were from regional centres to Dublin. 93% of patients required airway intervention before transfer (intubation or tracheostomy) and 32% needed inotropic support during transfer. The MICAS data confirm the demand for interhospital transport of critically ill patients and suggest that transfer using a centralised retrieval system is safe.

Abstract
This report summarizes recent literature relevant to the effects of terrorism on children's mental health. The paper addresses three aspects of this topic. In the first section of the paper, data are reviewed concerning the relationships among stress, trauma, and developmental psychopathology. A particular emphasis is placed on associations with indirect forms of trauma, given that terrorism involves high levels of indirect trauma. Second, the paper delineates a set of key principles to be considered when considering ways in which the effects of terrorism on children's mental health can be minimized. Third, data are reviewed from studies in developmental psychobiology. These data are designed to illustrate the mechanisms through which children exhibit unique effects in the wake of traumatic circumstances.
