A Low-Cost Wearable Device to Estimate Body Temperature Based on Wrist Temperature.

The remote monitoring of vital signs and healthcare provision has become an urgent necessity due to the impact of the COVID-19 pandemic on the world. Blood oxygen level, heart rate, and body temperature data are crucial for managing the disease and ensuring timely medical care. This study proposes a low-cost wearable device employing non-contact sensors to monitor, process, and visualize critical variables, focusing on body temperature measurement as a key health indicator. The wearable device developed offers a non-invasive and continuous method to gather wrist and forehead temperature data. However, since there is a discrepancy between wrist and actual forehead temperature, this study incorporates statistical methods and machine learning to estimate the core forehead temperature from the wrist. This research collects 2130 samples from 30 volunteers, and both the statistical least squares method and machine learning via linear regression are applied to analyze these data. It is observed that all models achieve a significant fit, but the third-degree polynomial model stands out in both approaches. It achieves an R2 value of 0.9769 in the statistical analysis and 0.9791 in machine learning.

Patients Age 40 Years and Younger With Multiple Myeloma Have the Same Prognosis as Older Patients: An Analysis of Real-World Patients' Evidence From Latin America.

PURPOSE: Multiple myeloma (MM) is a highly heterogeneous, incurable disease most frequently diagnosed in the elderly. Therefore, data on clinical characteristics and outcomes in the very young population are scarce. PATIENTS AND METHODS: We analyzed clinical characteristics, response to treatment, and survival in 103 patients with newly diagnosed MM age 40 years or younger compared with 256 patients age 41-50 years and 957 patients age 51 years or older. RESULTS: There were no statistical differences in sex, isotype, International Scoring System, renal involvement, hypercalcemia, anemia, dialysis, bony lesions, extramedullary disease, and lactate dehydrogenase (LDH). The most used regimen in young patients was cyclophosphamide, bortezomib, dexamethasone, followed by cyclophosphamide, thalidomide, dexamethasone and bortezomib, thalidomide, dexamethasone. Of the patients age 40 years or younger, only 53% received autologous stem-cell transplant (ASCT) and 71.1% received maintenance. There were no differences in overall survival (OS) in the three patient cohorts. In the multivariate analysis, only high LDH, high cytogenetic risk, and ASCT were statistically associated with survival. CONCLUSION: In conclusion, younger patients with MM in Latin America have similar clinical characteristics, responses, and OS compared with the elderly.

A Scoping Review of Biobehavioural Interventions to Improve PrEP Continuum of Care in Latin America.

According to the literature, biobehavioural interventions or combined strategies would reduce the risk of HIV infection by more than 7,000 new cases each day, which would contribute to the battle facing Latin America, where despite the high incidence and prevalence of HIV in the region, access to PrEP (pre-exposure prophylaxis) is very limited. The objective of this research was, consistent with the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), to conduct a scoping review to assess the evidence of available outcome data on biobehavioural interventions and programs to address gaps in the PrEP continuum of care in Latin America. The search was conducted in the databases EBSCOhost, WoS, Scopus, and ProQuest, and include all studies published from 2010 to 2021. One hundred eighty-six studies were identified and evaluated according to the eligibility criteria in six stages starting with the elimination of duplicates until the selection of studies that met the previously mentioned criteria; at the end five studies were chosen which were submitted to the methodological quality assessment including compliance with ethical guidelines. Results show that biobehavioural interventions promoting PrEP in Latin America are effective in increasing condom use, decreasing HIV risk, and increasing PrEP awareness, uptake, adherence, and retention. The limited number of interventions in the PrEP continuum of care indicates a need for the uptake of dissemination and implementation science (D&I) frameworks. D&I could help facilitate the translation of evidence-based practices, interventions, and policies to address the HIV crisis in Latin America.

Según la literatura, las intervenciones bioconductuales o estrategias combinadas reducirían el riesgo de infección por VIH en más de 7000 nuevos casos cada día, lo que contribuiría a la batalla que enfrenta América Latina, región en la que, a pesar de la alta incidencia y prevalencia del VIH, el acceso a la PrEP (profilaxis preexposición) es muy limitado. De acuerdo con las directrices de PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), el objetivo de esta investigación fue realizar una revisión de alcance para evaluar la evidencia de los datos de resultados disponibles sobre intervenciones bioconductuales y programas para abordar las brechas en el continuo de atención de PrEP en América Latina. La búsqueda se realizó en las bases de datos EBSCOhost, WoS, Scopus y ProQuest, e incluyó todos los estudios publicados de 2010 a 2021. Se identificaron ciento ochenta y seis estudios, y se evaluaron de acuerdo con los criterios de elegibilidad en seis etapas, iniciando por la eliminación de duplicados hasta la selección de estudios que cumplieran los criterios previamente mencionados; al final se eligieron cinco estudios, los cuales fueron sometidos a la evaluación de calidad metodológica, incluyendo el cumplimiento de los lineamientos éticos. Los resultados muestran que las intervenciones bioconductuales que promueven la PrEP en América Latina son efectivas para aumentar el uso del condón, disminuir el riesgo de VIH y aumentar la conciencia, la aceptación, la adherencia y la retención de la PrEP. El número limitado de intervenciones en el continuo de atención de la PrEP indica la necesidad de adoptar marcos científicos de difusión e implementación (D&I); marcos que podrían ayudar a facilitar la traducción de prácticas, intervenciones y políticas basadas en la evidencia para abordar la crisis del VIH en América Latina.

In a context that has tended towards globalization, in which obtaining economic resources is usually the driving force of societies, information resources have frequently been treated as private goods for which one must pay. A strategy for the above has been open and free access to information, a factor of great importance for the construction of more open media.

Feasibility and acceptability of CRiSOL: A pilot peer-based intervention to address syndemic health issues afflicting Latino immigrants in the U.S.

Substance use, HIV/AIDS, domestic violence and mental health (SAVAME) are syndemic health issues that disproportionately burden Latinos in the U.S. Yet, there are limited evidence-based interventions to address these interrelated syndemic issues and their shared socio-ecological determinants. This study sought to test the feasibility and acceptability of CRiSOL, a peer-based, resilience-focused intervention to reduce the impact of the SAVAME syndemic on Latino immigrants. Fifteen Latino immigrant community leaders were recruited and trained to serve as health promotion agents in their naturally existing social networks. The training was implemented with high fidelity, received with high satisfaction by the peer leaders, and associated with significant improvements in their knowledge, leadership skills, and social capital. During an 8-month outreach phase, nine leaders remained active in the program and documented 825 one-on-one interactions with community members, during which they provided advice/counseling (52.2% of interactions), health information/education (32.5%), referrals to health and social services (38.5%), food aid (39.9%), and service navigation/assistance (10.2%). While future research must be conducted to establish the effectiveness of CRiSOL, findings from this pilot evaluation indicate the feasibility, acceptability, and high level of reach of this intervention and suggest significant potential to reduce the SAVAME syndemic burden in Latino communities.

Clinical predictors and outcomes of pulmonary infarction in patients with central pulmonary embolism.

BACKGROUND: Given the heterogeneity of predisposing factors associated with pulmonary infarction (PI) and the lack of clinically relevant outcomes among patients with acute pulmonary embolism (PE) complicated by PI, further investigation is required. METHODS: Retrospective study of patients with central PE in an 11-year period. Data were stratified according to the diagnosis of PI. Multivariable logistic regression analysis was used to analyze factors associated with PI development and determine if PI was associated with severe hypoxemic respiratory failure and mechanical ventilation use. RESULTS: Of 645 patients with central PE, 24% (n = 156) had PI. After adjusting for demographics, comorbidities, and clinical features on admission, only age (OR 0.98, CI 0.96-0.99; p = 0.008) was independently associated with PI. Regarding outcomes, 35% (n = 55) had severe hypoxemic respiratory failure, and 19% (n = 29) required mechanical ventilation. After adjusting for demographics, PE severity, and right ventricular dysfunction, PI was independently associated with severe hypoxemic respiratory failure (OR 1.78; CI 1.18-2.69, p = 0.005) and mechanical ventilation (OR 1.92; CI 1.14-3.22, p = 0.013). CONCLUSIONS: Aging is a protective factor against PI. In acute central PE, subjects with PI had higher odds of developing severe hypoxemic respiratory failure and requiring mechanical ventilation.

Hepatitis C (HCV) among Black and Latino sexual minority men (SMM) in the Southern United States: Protocol of a prospective cohort epidemiological study.

BACKGROUND: Sexual minority men (SMM) who engage in condomless anal sex and injection drug use are at increased risk for viral Hepatitis C (HCV) infection. Additionally, studies have found racial disparities in HCV cases across the United States. However, very few epidemiological studies have examined factors associated with HCV infection in HIV-negative Black and Latino SMM. This paper describes the rationale, design, and methodology of a prospective epidemiological study to quantify the HCV prevalence and incidence and investigate the individual and environmental-level predictors of HCV infection among HIV-negative, Black and Latino SMM in the Southern U.S. METHODS: Beginning in September 2021, 400 Black and Latino SMM, aged 18 years and above, will be identified, recruited and retained over 12-months of follow-up from two study sites: greater Washington, DC and Dallas, TX areas. After written informed consent, participants will undergo integrated HIV/STI testing, including HCV, HIV, syphilis, gonorrhea, and chlamydia. Subsequently, participants will complete a quantitative survey-including a social and sexual network inventory-and an exit interview to review test results and confirm participants' contact information. Individual, interpersonal, and environmental factors will be assessed at baseline and follow-up visits (6 and 12 months). The primary outcomes are HCV prevalence and incidence. Secondary outcomes are sexual behavior, substance use, and psychosocial health. RESULTS: To date (March 2023) a total of 162 participants have completed baseline visits at the DC study site and 161 participants have completed baseline visits at the Texas study site. CONCLUSION: This study has several implications that will directly affect the health and wellness of Black and Latino SMM. Specifically, our results will inform more-focused HCV clinical guidelines (i.e., effective strategies for HCV screening among Black/Latino SMM), intervention development and other prevention and treatment activities and development of patient assistance programs for the treatment of HCV among uninsured persons, especially in Deep South, that have yet to expand Medicaid.

A microfluidic approach for label-free identification of small-sized microplastics in seawater.

Marine microplastics are emerging as a growing environmental concern due to their potential harm to marine biota. The substantial variations in their physical and chemical properties pose a significant challenge when it comes to sampling and characterizing small-sized microplastics. In this study, we introduce a novel microfluidic approach that simplifies the trapping and identification process of microplastics in surface seawater, eliminating the need for labeling. We examine various models, including support vector machine, random forest, convolutional neural network (CNN), and residual neural network (ResNet34), to assess their performance in identifying 11 common plastics. Our findings reveal that the CNN method outperforms the other models, achieving an impressive accuracy of 93% and a mean area under the curve of 98 ± 0.02%. Furthermore, we demonstrate that miniaturized devices can effectively trap and identify microplastics smaller than 50 µm. Overall, this proposed approach facilitates efficient sampling and identification of small-sized microplastics, potentially contributing to crucial long-term monitoring and treatment efforts.

Clinical features and risk factors of adverse clinical outcomes in central pulmonary embolism using machine learning analysis.

BACKGROUND: In prior studies, central pulmonary embolism (PE) was associated with high clot burden and was considered an independent predictor for thrombolysis. Further information about predictors of adverse outcomes in these patients is needed for better risk stratification. The objective is to describe independent predictors of adverse clinical outcomes in patients with central PE. METHODS: Large retrospective, observational, and single-center study of hospitalized patients with central PE. Data were gathered on demographics, comorbidities, clinical features on admission, imaging, treatments, and outcomes. Multivariable standard and Least Absolute Shrinkage and Selection Operator (LASSO) machine learning logistic regressions and sensitivity analyses were used to analyze factors associated with a composite of adverse clinical outcomes, including vasopressor use, mechanical ventilation, and inpatient mortality. RESULTS: A total of 654 patients had central PE. The mean age was 63.1 years, 59% were women, and 82% were African American. The composite adverse outcome was observed in 18% (n = 115) of patients. Serum creatinine elevation (odds ratio [OR] = 1.37, 95% CI = 1.20-1.57; p = 0.0001), white blood cell (WBC) count elevation (OR = 1.10, 95% CI = 1.05-1.15; p < 0.001), higher simplified pulmonary embolism severity index (sPESI) score (OR = 1.47, 95% CI = 1.18-1.84; p = 0.001), serum troponin elevation (OR = 1.26, 95% CI 1.02-1.56; p = 0.03), and respiratory rate increase (OR = 1.03, 95% CI = 1.0-1.05; p = 0.02) were independent predictors of adverse clinical outcomes. CONCLUSION: Among patients with central PE, higher sPESI score, WBC count elevation, serum creatinine elevation, serum troponin elevation, and respiratory rate increase were independent predictors of adverse clinical outcomes. Right ventricular dysfunction on imaging and saddle PE location did not predict adverse outcomes.

Clinical characteristics and treatment of patients with central pulmonary embolism and right heart thrombus.

INTRODUCTION: Right heart thrombus (RHT), also known as clot in transit, is an uncommon finding in pulmonary embolism (PE) that is associated with increased inpatient mortality. To date, there is no consensus on the management of RHT. Therefore, we aim to describe the clinical features, treatments, and outcomes of patients with simultaneous RHT and PE. METHODS: This is a retrospective, cross-sectional, and single-center study of hospitalized patients with central PE who had RHT visualized on transthoracic echocardiography (TTE) from January 2012 to May 2022. We use descriptive statistics to describe their clinical features, treatments, and outcomes, including mechanical ventilation, major bleeding, inpatient mortality, length of hospital stay, and recurrent PE on follow-up. RESULTS: Of 433 patients with central PE who underwent TTE, nine patients (2%) had RHT. The median age was 63 years (range 29-87), most were African American (6/9), and females (5/9). All patients had evidence of RV dysfunction and received therapeutic anticoagulation. Eight patients received RHT-directed interventions, including systemic thrombolysis (2/9), catheter-directed suction embolectomy (4/9), and surgical embolectomy (2/9). Regarding outcomes, 4/9 patients were hemodynamically unstable, 8/9 were hypoxemic, and 2/9 were mechanically ventilated. The median length of hospital stay was six days (range 1-16). One patient died during hospital admission, and two patients had recurrent PE. CONCLUSION: We described the different therapeutic approaches and outcomes of patients with RHT treated in our institution. Our study adds valuable information to the literature, as there is no consensus on the treatment of RHT. HIGHLIGHTS: Right heart thrombus (RHT) was a rare finding in central pulmonary embolism. Most patients with RHT had evidence of RV dysfunction and pulmonary hypertension. Most patients received RHT-directed therapies in addition to therapeutic anticoagulation.

Feasibility and Acceptability Pilot Test of Connecting Latinos en Parejas: A Couples-Based HIV Prevention Intervention for Latino Male Couples.

Despite recent emphasis on couples-based HIV prevention interventions, efficacious interventions for Latino male couples have yet to be tested. The study examined the feasibility and acceptability of the Connecting Latinos en Pareja (CLP) intervention, a couples-based HIV prevention intervention for Latino male couples. This pilot demonstrated high feasibility, meeting targets for recruitment, retention, and intervention completion. We recruited a diverse cohort of 46 individuals/23 couples with a retention rate of 80% over 6 months and a 100% intervention completion rate in both conditions (four structured couple sessions in each condition). This pilot RCT was not powered to detect significant intervention impact on the primary outcome; however, there was a significant increase in relationship functioning among couples in the intervention group relative to controls and promising trends in changes in several key outcome and mediating variables. Secondary analysis documented trends in the expected directions for several other key hypothesized mechanisms of action (stimulant use, psychological symptoms, quality of life) as well as the primary outcome of proportion of protected sex acts (overall and broken out by main vs. outside partners). Qualitative exit interviews revealed high levels of acceptability of the CLP intervention. Participants highlighted affective component of the intervention and perceived effectiveness in improving dyadic communication skills and safer sex practices. Our findings show that a pilot trial of CLP is highly feasible and acceptable, with CLP demonstrating promising evidence of changes in key intervention mechanisms.

Utilizing Community Based Participatory Research Methods in Black/African American and Hispanic/Latinx Communities in the US: The CDC Minority HIV Research Initiative (MARI-Round 4).

The Centers for Disease Control and Prevention Minority HIV Research Initiative (MARI) funded 8 investigators in 2016 to develop HIV prevention and treatment interventions in highly affected communities. We describe MARI studies who used community-based participatory research methods to inform the development of interventions in Black/African American and Hispanic/Latinx communities focused on sexual minority men (SMM) or heterosexual populations. Each study implemented best practice strategies for engaging with communities, informing recruitment strategies, navigating through the impacts of COVID-19, and disseminating findings. Best practice strategies common to all MARI studies included establishing community advisory boards, engaging community members in all stages of HIV research, and integrating technology to sustain interventions during the COVID-19 pandemic. Implementing community-informed approaches is crucial to intervention uptake and long-term sustainability in communities of color. MARI investigators' research studies provide a framework for developing effective programs tailored to reducing HIV-related racial/ethnic disparities.

Molecular and Antimicrobial Susceptibility Characterization of Escherichia coli Isolates from Bovine Slaughterhouse Process.

Antimicrobials are routinely used in human and veterinary medicine. With repeated exposure, antimicrobials promote antibiotic resistance, which poses a threat to public health. In this study, we aimed to determine the susceptibility patterns, virulence factors, and phylogroups of E. coli isolates during the killing process in a bovine slaughterhouse. We analyzed 336 samples (from water, surfaces, carcasses, and feces), and 83.3% (280/336) were positive for E. coli. The most common phenotypic resistances that we detected were 50.7% (142/280) for tetracycline, 44.2% (124/280) for cephalothin, 34.6% (97/280) for streptomycin, and 36.7% (103/280) for ampicillin. A total of 82.4% of the isolates had resistance for at least one antimicrobial, and 37.5% presented multiresistance. We detected a total of 69 different phenotypic resistance patterns. We detected six other resistance-related genes, the most prevalent being tetA (22.5%) and strB (15.7%). The prevalence values of the virulence genes were 5.4% in hlyA, 1.4% in stx1, and 0.7% in stx2. The frequencies of the pathogenic strains (B2 and D) were 32.8% (92/280) and 67.1% (188/280) as commensals A and B1, respectively. E. coli isolates with pathogenic potential and multiresistance may represent an important source of dissemination and a risk to consumers.

Using the Meaningful Involvement of People Living with HIV/AIDS (MIPA) Framework to Assess the Engagement of Sexual Minority Men of Color in the US HIV Response: a Literature Review.

Black and Latino sexual minority men (SMM) continue to be disproportionately impacted by HIV. We utilized eight components of the Meaningful Involvement of People Living with HIV/AIDS (MIPA) framework to assess the engagement of Black and Latino SMM. Thirty-six (36) studies were included in the literature review. Forty-two percent of studies were Black SMM-specific, followed by Latino SMM-specific (31%) studies. Twenty-eight percent of studies were conducted among both groups. Most studies (72%) were intervention-related and focused on HIV prevention. The top five most common methods of community engagement were focus groups (39%), followed by interviews (36%), community-based participatory research (14%), the utilization of community advisory boards or peer mentorship (11%), and the establishment of multi-stakeholder coalitions, observations, or surveys (8%). We documented at least 7 MIPA components in 47% of the included studies. Community-based participatory research was more commonly utilized to engage Latino SMM. Researchers were more likely to initiate the engagement across all included studies. Few studies documented how Black and Latino SMM perceived the engagement. Engagement responsiveness was a well-documented MIPA component. In terms of engagement power dynamics, there were several examples of power imbalances, especially among Black SMM-specific studies. The inclusion of Black and Latino SMM had robust impacts on HIV research and interventions. There were limited examples of engagement capacity and maintenance. This is one of the first studies focused on utilizing MIPA to document the engagement of SMM of color. MIPA served as a useful framework for understanding the engagement of SMM of color in the US HIV response. The engagement of SMM of color is critical to reducing health inequities.
