Understanding the Link Between Adolescent Same-Gender Contact and Unintended Pregnancy: The Role of Early Adversity and Sexual Risk Behavior

Past research suggests an apparent paradox: Women who engage in same-gender sexual behavior show higher rates of unintended pregnancy than women with exclusive other-gender sexual behavior. Such women also have disproportionate rates of early adversity (both harshness, such as abuse or neglect, and unpredictability, such as father absence). We used the Add Health data (N?=?5,617 cisgender women) to examine the relative contributions of early adversity, adolescent same-gender sexual behavior, and general sexual risk behavior to women’s risks for adult unintended pregnancy. Women who engaged in adolescent same-gender sexual behavior were more likely to report childhood adversity, and both childhood adversity and adolescent same-gender behavior made independent contributions to subsequent rates of unintended pregnancy. The association between adolescent same-gender sexual behavior and adult unintended pregnancy was partially attributable to the fact that women with adolescent same-gender sexual behavior engaged in greater sexual risk behavior more broadly. These findings suggest that same-gender sexual behavior in adolescence may relate to a broader set of sexual risk behaviors that augment future risk for unintended pregnancy, independent of sexual identity. We draw on life history theory to explain this pattern of results and suggest directions for future research.

     

Examining the Macrosystem Level of Influence on Community Health Worker Effectiveness in the State of Nebraska: A Qualitative Approach

Community health workers (CHWs) serve as the linkage between community and providers and are stakeholders for bridging services to the public. However, integration of CHWs into health care organizations is often lacking. This study explored macrosystem level barriers faced by CHWs and their ability to do their jobs effectively. Using qualitative interviews from CHWs (n?=?28) in Nebraska, we used an abductive approach to derive the following themes: (1) CHWs and client macrosystem barriers, (2) CHW workforce supports, and (3) macrosystem solutions for CHW workforce sustainability. Study results also found various macrosystem barriers affecting CHW workforces including immigration policies, insurance policies, funding sources, supervisor support, and obstacles for health seeking of clients. Moreover, through the lens of CHWs, results revealed the need to provide and advocate for solutions that prioritize the needs of CHWs as they continue to fill a crucial gap in community healthcare systems.

     

Cementless Hemiarthroplasty for Intracapsular Femoral Neck Fractures in the Octa- and Nonagenarians

BackgroudCurrent evidence supports the use of cemented hemiarthroplasty for treatment of intracapsular femoral neck fractures since it is associated with a lower risk of implant-related complications. However, many medical centers employ the cementless technique for the frail elderly population because it is faster and has lower cardiovascular risks and perioperative mortality. This observational study reports the outcomes of cementless bipolar hemiarthroplasty for intracapsular femoral neck fractures in patients aged 80 years and older.MethodsA total of 424 patients (female, 77.1%) with a mean age of 86.9 years were operated for intracapsular femoral neck fractures between January 2009 and December 2017. Of those, 66.7% had an American Society of Anaesthesiologists (ASA) score of 3 or more. All operations were performed with the posterolateral surgical approach and all patients received a cementless stem. Intraoperative and perioperative values and in-hospital outcomes were evaluated, and clinical and radiographical follow-up was done at 40 days, 90 days, and when possible between 5 months and 12 months postoperatively. Multivariate analysis was performed to evaluate if there were factors affecting mortality.ResultsThe mean operative time was 50 minutes. There were no deaths intraoperatively. Intraoperative periprosthetic fractures occurred in 2.1% of the cases with 66.7% of them fixed through cerclage wires intraoperatively. The median length of hospitalization was 11 days (interquartile range, 8.75–15) and 2.4% of patients died while in hospital after surgery. Approximately 91.5% of patients presented with perioperative anemia. Only 1.9% of the complications were related to the implant, 62.5% of which were dislocations. More than 90% of patients were ambulatory either autonomously or with support at each follow-up assessment. Age, male sex, and higher ASA score were related to increased mortality.ConclusionsDespite some limitations, this observational study underlines that a cementless femoral stem of modern design can give good clinical outcomes, thus being an appropriate solution especially for the frail elderly.     

Universal HIV testing and treatment and HIV stigma reduction: a comparative thematic analysis of qualitative data from the HPTN 071 (PopART) trial in South Africa and Zambia

Despite continued development of effective HIV treatment, expanded access to care and advances in prevention modalities, HIV‐related stigma persists. We examine how, in the context of a universal HIV‐testing and treatment trial in South Africa and Zambia, increased availability of HIV services influenced conceptualisations of HIV. Using qualitative data, we explore people’s stigma‐related experiences of living in ‘intervention’ and ‘control’ study communities. We conducted exploratory data analysis from a qualitative cohort of 150 households in 13 study communities, collected between 2016 and 2018. We found that increased availability of HIV‐testing services influenced conceptualisations of HIV as normative (non‐exceptional) and the visibility of people living with HIV (PLHIV) in household and community spaces impacted opportunities for stigma. There was a shift in community narratives towards individual responsibility to take up (assumingly) widely available service – for PLHIV to take care of their own health and to prevent onward transmission. Based on empirical data, we show that, despite a growing acceptance of HIV‐related testing services, anticipated stigma persists through the mechanism of shifting responsibilisation. To mitigate the responsibilisation of PLHIV, heath implementers need to adapt anti‐stigma messaging and especially focus on anticipated stigma.     

Competencies and problems reported by parents of Greek and American children,ages 6–11

This study compared parent-reported competencies and behavioral/emotional problems in demographically-matched samples of Greek and American children, ages 6–11. Parents of 356 children of each nationality completed the Child Behavior Checklist (CBCL). Competence scores were higher for American children, except on Academic Competence, where scores were higher for Greek children. Greek scores were significantly higher than American scores on the Withdrawn, Anxious/Depressed, Attention Problems, Delinquent Behavior, Aggressive Behavior, Internalizing, Externalizing, and Total Problem scales. On the Anxious/Depressed syndrome, nationality accounted for 14% of the variance. There were few main effects for sex and age and fewer interactions. The higher problem scores in the Greek sample were partly due to the tendency of Greek parents to use extreme item scores. When items were scored present v. absent, Greek scores were higher only on Withdrawn, Anxious/Depressed, Internalizing, and Total Problems, while American scores were higher on Somatic Complaints and Thought Problems. Nationality differences in rates of referral for mental health services and sample differences in exclusion criteria for prior mental health services may have contributed to differences in problem scores. Results are compared to findings from other cross-cultural studies.

Zusammenfassung Diese Studie vergleicht die Fähigkeiten und Verhaltens- bzw. emotionalen Auffälligkeiten in demographisch parallelisierten Stichproben von griechischen und amerikanischen Kindern im Alter von 6-11 Jahren. Die Eltern von 356 Kindern der beiden Nationalitäten füllten die Child Behavior Checklist (CBCL) aus. Die Kompetenzwerte waren bei den amerikanischen Kindern mit Ausnahme der akademischen Fähigkeiten höher. Die griechischen Werte waren signifikant höher als die amerikanischen im Hinblick auf die Skalen Zurückhaltung, ängstlich/depressiv, Aufmerksamkeitsstörungen, delinquentes Verhalten, aggressives Verhalten, Internalisation, Externalisation und Gesamtauffälligkeiten. Im Hinblick auf das ängstlich/depressive Syndrom war die Nationalität für 14% der Varianz verantwortlich. Nur vereinzelt wurden Haupteffekte im Hinblick auf Geschlecht und Alter und eine geringere Anzahl Interaktionen festgestellt. Die höheren Problemwerte in der griechischen Stichprobe waren teilweise durch die Tendenz der griechischen Eltern bedingt, extreme Werte anzukreuzen. Bei den Items, die als vorhanden bzw. nicht vorhanden gewertet werden mußten, waren die griechischen Werte nur bei den Skalen Zurückhaltung, ängstlich/depressiv, Internalisation und Gesamtprobleme höher, während amerikanische Werte für die Skalen körperliche Beschwerden und Denkstörungen höher lagen. Nationalitätsunterschiede der Zuweisungsraten zu psychosozialen Diensten und Stichprobenunterschieden im Hinblick auf die Ausschlußkriterien für vorangegangene Inanspruchnahme psychosozialer Dienste könnten zu den unterschiedlichen Problemwerten beigetragen haben. Die Ergebnisse werden verglichen mit anderen transkulturellen Studien.

Résumé Cette étude a comparé les compétences et les problèmes de comportement et affectifs rapportés par les parents d'un échantillon d'enfants grecs et américains âgés de 6 à 11 ans appariés démographiquement. Les parents de 356 enfants de chaque nationalité ont rempli la Child Behavior Checklist (CBCL). Les scores de compétence étaient plus élevés pour les enfants américains excepté pour la compétence scolaire pour laquelle les scores étaient plus élevés chez les enfants grecs. Les scores grecs étaient significativement plus hauts que les scores américains quant au retrait, l'anxiété-dépression, les problèmes d'attention, le comportement délinquant, le comportement agressif, les échelles d'internalisation, d'externalisation et de problèmes totaux. Pour le syndrome anxiodépressif, la nationalité intervenait pour une variance de 14%. Il y avait peu d'effets principaux en ce qui concerne le sexe et l'âge. Les scores de problèmes les plus élevés dans les échantillons grecs étaient en partie dûs à la tendance des parents grecs à utiliser des items extrêmes. Quand les items étaient cotés présents versus absents, les scores grecs étaient plus élevés seulement en ce qui concerne le retrait, l'anxiété-dépression, l'internalisation et les problèmes totaux tandis que les scores américains étaient plus hauts en ce qui concerne les plaintes somatiques et les problèmes de pensée. Les différences de nationalité en ce qui concerne les taux de référence à des services de santé mentale et les différences des échantillons dans les critères d'exclusion pour l'utilisation antérieure de services de santé mentale, peuvent avoir contribué aux différences dans les scores de problèmes. Les résultats sont comparés aux autres études transculturelles.

     

Assessment of myocardial viability by dynamic tomographic iodine 123 iodophenylpentadecanoic acid imaging: Comparison with rest-redistribution thallium 201 imaging

Background

This study examined the ability of dynamic ¹²³I-labeled iodophenylpentade-canoic acid (IPPA) imaging to detect myocardial viability in patients with left ventricular (LV) dysfunction caused by coronary artery disease.

Methods and Results

Serial 180-degree single-photon emission computed tomographic (SPECT) images (five sets, 8 minutes each) were obtained starting 4 minutes after injection of 2 to 6 mCi ¹²³I at rest in 21 patients with LV dysfunction (ejection fraction [EF] 34%±11%). The segmental uptake was compared with that of rest-redistribution ²⁰¹Tl images (20 segments/study). The number of perfusion defects (reversible and fixed) was similar by IPPA and thallium (11±5 vs 10±5 segments/patient; difference not significant). There was agreement between IPPA and thallium for presence or absence (κ=0.78±0.03) and nature (reversible, mild fixed, or severe fixed) of perfusion defects (κ=0.54±0.04). However, there were more reversible IPPA defects than reversible thallium defects (7±4 vs 3±4 segments/patient; p=0.001). In 14 patients the EF (by gated pool imaging) improved after coronary revascularization from 33%±11% to 39%±12% (p=0.002). The number of reversible IPPA defects was greater in the seven patients who had improvement in EF than in the patients without such improvement (10±4 vs 5±4 segments/patient; p=0.075).

Conclusions

¹²³I-labeled IPPA SPECT imaging is a promising new technique for assessment of viability. Reversible defects predict recovery of LV dysfunction after coronary revascularization.     

Core competencies for preventive medicine residents: Version 2.0

During the early 1990s, the American College of Preventive Medicine (ACPM), with support from the Health Resources and Services Administration (HRSA), identified core competencies and performance indicators (measures to assess their achievement) for all preventive medicine residents. After the competencies were approved, distributed by the ACPM and HRSA, and published in the American Journal of Preventive Medicine, they were integrated in various ways into the operation of individual residency programs. Changes in the health care system during the decade, however, necessitated an update of the original competencies to better equip preventive medicine educators to prepare residents for new roles those in preventive medicine can play in a restructured health care system. HRSA funded an effort to produce Version 2.0 of the preventive medicine competencies based on review and refinement of the original competencies through a consensus process. This article includes these revised core competencies and performance indicators.
