This study assessed AIDS knowledge among Latino adults in New Jersey according to acculturation and socioeconomic status. Data on 121 Latino adults were collected in spring 2000 using bilingual telephone interviews. Respondents were selected using the Census' Latino surname methodology. Items were adapted from the National Health Interview Survey Supplement on AIDS Knowledge and Attitudes and the Marin acculturation scale. AIDS knowledge was more strongly associated with language exposure than with self-assessed English or Spanish language abilities. Low educational attainment and bilingual language exposure were associated with lower AIDS knowledge; when other factors were controlled, place of schooling, length of time in the United States, age and gender were not statistically significant. Transmission of HIV via casual contact was widely misunderstood, bu...

It has also provided an opportunity for innovation using a virtual platform. Tele-ultrasound and video-conferencing are alternative and supportive tools to augment global POCUS education and training. There is a need to support learners and experts to ensure that maximum benefit is gained from the use of these innovative modalities.

In this cross-sectional pilot study, the 15 most abundant 16S taxa in the anal microbiota of 113 MSM underwent unsupervised K-means clustering and z-score comparisons to define similarities and dissimilarities among 4 microbiota taxonomic profiles. Distributions of oncogenic HPV (high-risk human papillomavirus [HR-HPV]), concurrent HIV, antiretroviral therapy (ART), and other clinical and behavioral data were evaluated using Fisher's exact and Kruskal-Wallis tests to determine biological signatures of cluster membership. Prevotella was consistently represented in each cluster, but the average composition ranged from 14% to 44%. Cluster 2 was enriched with a member of the Fusobacteria phylum, Sneathia (29%). More participants of cluster 2 were HIV infected and taking ART (83%, 5/6), ...

However, especially for pregnant and morbid obese patients and children, these techniques can be challenging. We tested the success of point-of-care ultrasound in the evaluation of cervical traumas. Methods: This is a case series of cervical vertebra imaging with ultrasound in emergency department. We used linear probe and placed it anterolaterally to the neck, parallel to cervical spine. Images were obtained by an ultrasound-certified emergency physician. The height of the anterior wall of vertebral body, irregularity in vertebral body, and intervertebral space were assessed. Results: We presented a case series of six patients. Ultrasound images of cervical vertebral bodies and intervertebral spaces were able to obtain for all the patients. Any pathology was not observed in ultrasound imaging. This finding was compatible with cervical X-ray and CT scans and all the patients were discharged. Conclusions: However, this is a case series report of minor cervical trauma, and we were able to obtain ultrasound images of cervical vertebra bodies with point-of-care ultrasound examination by an emergency physician. This technique can be important for the patients contraindicated to CT or MRI. Also, it can give additional information to X-ray and CT scans especially for soft tissues.

Prompt resuscitation and decisive action are mandatory for patients who present in extremis, whereas a thorough diagnostic evaluation and appropriate observation are indicated in less compelling circumstances. Clinical skill and judgment along with plain radiographs provide the basis for treatment in most cases. More sophisticated imaging techniques, with the exception of angiography, are of limited value. A systematic approach based on wound location, be it central, peripheral, or proximate to the diaphragm, should result in timely resuscitation and sound diagnostic evaluation.

These challenges may result in the loss of highly trained individuals from LMICs and reduce the availability of local expertise to develop/inform best practices in health care and to direct locally relevant research. The path of training of LMIC researchers in high-income countries is well documented. However, strategies for a successful reintegration of biomedical researchers back to their home research institutions in LMICs are less clear. We report observations of workshops addressing repatriation needs of researchers returning to their home countries after training abroad during the American Society of Tropical Medicine and Hygiene (ASTMH) 2017 and 2018 annual meetings. Strategies proposed include maintaining connections with the...

As a result, the objective of this study was to assess diagnostic imaging capacity focusing on ultrasound in Zanzibar, including health care providers’ (HCPs) current training, use, and barriers to implementation. Methods: A previously published ultrasound needs assessment survey was modified and administered on-site at the eight public hospitals in Zanzibar among a convenience sample of HCPs. Demographics, perceived US needs, current training and practice, and availability of specialty support were assessed. HCPs also completed focused personal interviews (FPIs) to explore experience with training, interests, and barriers to ultrasound. On-site diagnostic imaging modalities were assessed. Results: There were nine ultrasound machines present at six of t...

This study evaluated noncommercial gel recipes compared to commercial gel. A search for US gel formulations revealed 6 recipes. Half-strength commercial gel and a modified glucomannan recipe were also tested. Nine gels, including commercial gel, were tested in Liberia and the United States. In each session, 2 physician sonologists evaluated 9 gels on 2 models, obtaining videos from the hepatorenal space with a curvilinear transducer, the cardiac parasternal long view with a phased array transducer, and the left basilic vein with a linear transducer. The sonologists and models, who were blinded to gel identity, made independent quantitative and qualitative gel evaluations comparing the test gel to commercial gel. Two physician sonologists who were blinded to the gel identities and a US operator reviewed the images and rated their quality. An analysis of variance in repeated measures was performed...
