Employing an innovative underwater camera to improve electronic monitoring in the commercial Gulf of Mexico reef fish fishery.

Vessel electronic monitoring (EM) systems used in fisheries around the world apply a variety of cameras to record catch as it is brought on deck and during fish processing activities. In EM work conducted by the Center for Fisheries Electronic Monitoring at Mote (CFEMM) in the Gulf of Mexico commercial reef fish fishery, there was a need to improve upon current technologies to enhance camera views for accurate species identification of large sharks, particularly those that were released while underwater at the vessel side or underneath the hull. This paper describes how this problem was addressed with the development of the first known EM system integrated underwater camera (UCAM) with a specialized vessel-specific deployment device on a bottom longline reef fish vessel. Data are presented based on blind video reviews from CFEMM trained reviewers of the resulting UCAM video footage compared with video from only the overhead EM cameras from 68 gear retrievals collected from eight fishing trips. Results revealed that the UCAM was a successful tool for capturing clear underwater video footage of released large (>2m) sharks to enable reviewers to improve individual species identification, determination, and fate by 34.4%. This was particularly important for obtaining data on incidental catches of large protected shark species. It also provided clear underwater imagery of the presence of potential predators such as marine mammals close to the vessel, more specifically bottlenose dolphin (Tursiops truncatus) during gear retrieval, which often damaged or removed catch. This information is intended to assist researchers in need of gathering critical data on bycatch in close proximity to a vessel in which conventional overhead EM cameras are limited.

Systematic review of existing literature regarding the prevalence of pediatric atopic dermatitis in Honduras.

Background: Atopic dermatitis (AD) is an inflammatory skin condition, often multifactorial in origin, and most commonly manifests during childhood. Although there remains a deficit in literature, current data suggest Honduras may have the highest prevalence and severity of AD among all Latin American countries. Objective: To assess the current prevalence of pediatric AD in Honduras and evaluate existing gaps in available literature to monitor disease burden. Methods: A comprehensive literature search was performed in March 2023. Articles were removed if they were published before 2007, were of the incorrect study design, or were focused on countries outside of Honduras. The articles were independently reviewed by 2 authors. Results: The initial literature search yielded 174 studies, of which 7 met inclusion criteria. AD prevalence rates in children in Honduras ranged from 0.7% to 40.0%. Limitations: Limitations include elements of study design, analytic methods, study populations, and limited articles. Conclusion: There appears to be a disproportionately higher prevalence and disease burden of pediatric AD in Honduras. Future research should acquire accurate data to further understand the prevalence, incidence, and severity of AD in Honduras.

Use of an elastic-scattering spectroscopy and artificial intelligence device in the assessment of lesions suggestive of skin cancer: A comparative effectiveness study.

Background: Skin cancer is the most common form of cancer worldwide. As artificial intelligence (AI) expands its scope within dermatology, leveraging technology may aid skin cancer detection. Objective: To assess the safety and effectiveness of an elastic-scattering spectroscopy (ESS) device in evaluating lesions suggestive of skin cancer. Methods: This prospective, multicenter clinical validation study was conducted at 4 US investigational sites. Patients with skin lesions suggestive of melanoma and nonmelanoma skin cancers were clinically assessed by expert dermatologists and evaluated by a device using AI algorithms comparing current ESS lesion readings with training data sets. Statistical analyses included sensitivity, specificity, AUROC, negative predictive value (NPV), and positive predictive value (PPV). Results: Overall device sensitivity was 97.04%, with subgroup sensitivity of 96.67% for melanoma, 97.22% for basal cell carcinoma, and 97.01% for squamous cell carcinoma. No statistically significant difference was found between the device and dermatologist performance (P = .8203). Overall specificity of the device was 26.22%. Overall NPV of the device was 89.58% and PPV was 57.54%. Conclusion: The ESS device demonstrated high sensitivity in detecting skin cancer. Use of this device may assist primary care clinicians in assessing suspicious lesions, potentially reducing skin cancer morbidity and mortality through expedited and enhanced detection and intervention.

Myocarditis Following COVID-19 Vaccination: A Systematic Review of Case Reports.

Introduction: COVID-19, the infectious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), often presents with a spectrum of symptoms at varying levels of severity, ranging from asymptomatic patients to those with fatal complications, such as myocarditis. With increased availability of COVID-19 vaccines, the awareness of possible side effects has expanded as reports surface. This study reviewed cases of myocarditis following COVID-19 vaccination and with existing literature on COVID-19 infection-induced myocarditis to compare clinical courses and analyze possible mechanisms of action. Methods: A systematic review of literature was conducted to identify published case reports (as of February 3, 2022) pertaining to the development of myocarditis following COVID-19 vaccination with either Pfizer or Moderna for an in-depth analysis. Additional subgroup analyses were conducted based on age, past medical history, vaccine manufacturer, and dose number. Results: There were 53 eligible case reports that were included in this study. Patients were mostly male with a median age of 24 years, and the most reported symptom upon presentation was chest pain. Seventy percent of the cases involved the Pfizer vaccine with a majority of myocarditis developing subsequent to second dose. Resolution of symptoms was achieved in all but one patient. Clinical severity, as measured primarily by left ventricular ejection fraction, appeared to be worse among adult patients than pediatric, as well as for patients with comorbidities. Conclusion: This study revealed an observable association between COVID-19 vaccines and myocarditis. However, the clinical course and prognosis seem favorable and less prevalent than those conferred from natural infection.

Blood Analyte Changes of Wild-Caught Adult Almaco Jack in Response to Acclimation to Recirculating Aquaculture Systems and Hyposalinity Treatment.

Despite the utility of blood analyte evaluation as a diagnostic tool to assist in monitoring the health of marine fishes, baseline data are often lacking for many commercially important finfish species. The objective of this study was to compare hematology and plasma chemistry data for adult wild-caught Almaco Jack Seriola rivoliana at time of capture and again following a period of acclimation to a recirculating aquaculture system and hyposalinity treatment. A total of 30 clinically healthy adult fish were caught via hook and line in the eastern Gulf of Mexico, approximately 120 mi offshore from Madeira Beach, Florida. Blood was collected from a subset of these fish (n = 13) immediately after capture and again at 16 weeks postcapture from another subset (n = 12) following a 45-d antiparasitic hyposalinity treatment. A 19% increase in fish body weight was observed during the study period (16 weeks) and no overt health issues or mortality were noted. Compared to fish that were sampled immediately following capture, several significant differences (P < 0.05) were observed. Absolute white blood cells were lower in captive held fish, suggesting biological variation, antigenic stimulation in wild fish, and/or immunosuppression associated with stress in captive held fish. Lower sodium, chloride, and calculated osmolality indicate osmoregulatory adjustments following the hyposalinity treatment by 16 weeks postcapture. Other observed plasma biochemical differences presumptively reflect dietary and/or environmental changes, or physiological variation following acclimation to captive culture conditions. This study reports baseline blood analyte data of wild-caught Almaco Jack and documents hematological and plasma biochemical responses to their new environment as captive broodstock. Baseline hematological and plasma biochemistry data obtained during this study are the first reported for this species.

Can palliative care integrated within HIV outpatient settings improve pain and symptom control in a low-income country? A prospective, longitudinal, controlled intervention evaluation.

A high burden of pain, symptoms and other multidimensional problems persist alongside HIV treatment. WHO policy indicates palliative care as essential throughout the disease course. This study aimed to determine whether palliative care delivered from within an existing HIV outpatient setting improves control of pain and symptoms compared to standard care. A prospective, longitudinal controlled design compared patient outcomes at an outpatient facility that introduced palliative care training to clinicians and stocked essential palliative care drugs, to outcomes of a cohort of patients at a similar HIV care facility with no palliative care, in Tanzania. Inclusion criteria were clinically significant pain or symptoms. Patients were followed from baseline fortnightly until week 10 using validated self-report outcome measures. For the primary pain outcome, the required sample size of 120 patients was recruited. Odds of reporting pain reduced significantly more at intervention site (OR=0.60, 95% CI 0.50-0.72) than at control (OR=0.85, 95% CI 0.80-0.90), p=0.001. For secondary outcomes, longitudinal analysis revealed significant difference in slope between intervention and control, respectively: Medical Outcomes Study-HIV (MOS-HIV) physical score 1.46 vs. 0.54, p=0.002; MOS-HIV mental health 1.13 vs. 0.26, p=0.006; and POS total score 0.84 vs. 0.18, p=0.001. Neither baseline CD4 nor antiretroviral therapy (ART) use was associated with outcome scores. These data are the first to report outcomes evaluating integrated HIV outpatient palliative care in the presence of ART. The data offer substantive evidence to underpin the existing WHO clinical guidance that states an essential role for palliative care alongside HIV treatment, regardless of prognosis.
