Neoadjuvant T-DM1 for HER2-positive breast cancer used as a bridging strategy during COVID-19 pandemic: lessons learned-a case series.

Background: Coronavirus disease 19 (COVID-19) has played a pivotal role in changing medical care around the world. During the pandemic, the operating rooms (ORs) were closed to elective surgery. Since breast cancer surgery is not regarded as an emergent procedure, there was an adoption of treatment regimen modification due to delays in treatment. Therefore, a decision was made to bridge early-stage HER2-positive breast cancer patients with neoadjuvant treatment to postpone surgery. Consequently, to reduce the frequency of dosing and the number of visits, as well as avoid steroid premedication, these patients were treated with ado-trastuzumab emtansine (T-DM1) every three weeks as opposed to weekly taxol and herceptin (TH). Case Description: Five patients with early-stage HER2-positive cancer were treated with neoadjuvant T-DM1 3.6 mg/kg IV every three weeks. Three of the five patients developed cancer progression identified by their physical exam and/or imaging. T-DM1 was discontinued, and all three patients underwent immediate surgery. The remaining two patients, 4 and 5, had a complete and partial pathological response, respectively. All five patients received adjuvant therapy after surgery, and currently, none of these patients show evidence of disease on follow-up. Conclusions: Our findings underscore the obstacles and treatment challenges encountered during the COVID-19 pandemic while preventing the spread of the virus and cancer progression. Furthermore, the use of T-DM1 for neoadjuvant treatment remains controversial, particularly when T-DM1 is used as a bridge to surgery during critical times. Perhaps better patient selection or a different drug regimen could have resulted in a better outcome in our study.

Evaluating the Impact of a Virtual Health Coaching Lifestyle Program on Weight Loss after Sleeve Gastrectomy: A Prospective Study.

Bariatric surgery (BS) is a leading treatment for obesity; however, adverse side effects (e.g., pain and infection) can deter patients or affect weight maintenance. This study investigates how a post-operative virtual health coaching lifestyle program, monitoring virtual weekly goal progress made by patients, affects weight loss after BS, specifically sleeve gastrectomy. Patients recruited for this 6-month study were classified with a BMI > 30 kg/m2 90 days post-operatively. Patients were prescribed lifestyle support delivered by certified health and wellness coaches (InHealth Lifestyle Therapeutics™). Demographic variables (e.g., age, weight, height, and gender) were obtained and compared according to initial, 3-, 6-month, and current weight through repeated measures ANOVA and post hoc comparison. Thirty-eight adult participants were included, with a mean age of 52 years ± 12.9 and with a majority (n = 35; 97%) of them being female. There were significant differences in weight reported across all five time points (p < 0.05), with the greatest weight difference seen between the initial (250.3 ± 45.5 lbs.) and final time points (226.7± 40.4 lbs.). This study suggests post-operative virtual health coaching can enhance weight loss outcomes after sleeve gastrectomy. Further research is needed to assess the long-term effects and cost-effectiveness of such a form of coaching for bariatric surgery patients.

Prevalence, Clinical Severity, and Serotype Distribution of Pneumococcal Pneumonia Among Adults Hospitalized With Community-Acquired Pneumonia in Tennessee and Georgia, 2018-2022.

INTRODUCTION: Understanding the pneumococcal serotypes causing community-acquired pneumonia (CAP) is essential for evaluating the impact of pneumococcal vaccines. METHODS: We conducted a prospective surveillance study of adults aged ≥18 years hospitalized with CAP at 3 hospitals in Tennessee and Georgia between 1 September 2018 and 31 October 2022. We assessed for pneumococcal etiology with cultures, the BinaxNOW urinary antigen detection test, and serotype-specific urinary antigen detection assays that detect 30 pneumococcal serotypes contained in the investigational pneumococcal conjugate vaccine V116, as well as licensed vaccines PCV15 and PCV20 (except serotype 15B). The distribution of pneumococcal serotypes was calculated based on serotype-specific urinary antigen detection results. RESULTS: Among 2917 hospitalized adults enrolled with CAP, 352 (12.1%) patients had Streptococcus pneumoniae detected, including 51 (1.7%) patients with invasive pneumococcal pneumonia. The 8 most commonly detected serotypes were: 3, 22F, 19A, 35B, 9N, 19F, 23A, and 11A. Among 2917 adults with CAP, 272 (9.3%) had a serotype detected that is contained in V116, compared to 196 (6.7%) patients with a serotype contained in PCV20 (P < .001), and 168 (5.8%) patients with a serotype contained in PCV15 (P < .001). A serotype contained in V116 but not PCV15 or PCV20 was detected in 120 (4.1%) patients, representing 38.0% of serotype detections. CONCLUSIONS: Approximately 12% of adults hospitalized with CAP had S. pneumoniae detected, and approximately one-third of the detected pneumococcal serotypes were not contained in PCV15 or PCV20. Development of new pneumococcal vaccines with expanded serotype coverage has the potential to prevent a substantial burden of disease.

Qualification of a 21-valent pneumococcal urine antigen detection assay and development of clinical positivity cutoffs.

Aim: Serotype-specific assays detecting pneumococcal polysaccharides in bodily fluids are needed to understand the pneumococcal serotype distribution in non-bacteremic pneumonia. Methods: We developed a urine antigen detection assay and using urine samples from adult outpatients without pneumonia developed positivity cutoffs for both a previously published 15-valent and the new 21-valent assay. Clinical sensitivity was confirmed with samples from patients with invasive pneumococcal disease. Results: Total assay precision ranged from 7.6 to 17.8% coefficient of variation while accuracy ranged between 80 and 150% recovery, except for three serotypes where recoveries ranged from 32 to 60%. Clinical sensitivity was 86.4% and specificity was 96.5% across all 30 serotypes. Conclusion: The assay could potentially assess serotype-distribution in non-infected and infected participants with pneumococcal disease.

Axillary Reverse Mapping Aids in Reducing the Rates of Breast Cancer-Related Lymphedema in Underserved Ethnically Diverse Population.

BACKGROUND: Breast cancer-related lymphedema (BCRL) poses a significant risk following sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND), particularly affecting ethnic minorities, with a twofold increased risk. Axillary reverse mapping (ARM), a novel technique, shows potential in reducing BCRL rates, yet its utility in ethnic minorities lacks sufficient exploration. Therefore, our study aims to investigate the utility and outcomes of ARM on BCRL in an ethnic diverse group. METHODS: A retrospective chart review of ARM patients from January 2019 to July 2022 was conducted, monitoring patients over 24 months at 3-month intervals using SOZO® scores, with comparisons with preoperative baselines. RESULTS: Of the 212 patients, 83% belonged to ethnic minorities. SLNB was performed in 83%, ALND in 17%, and 62.3% underwent radiation therapy. Positive lymph nodes were found in 31.6%, with 22.2% exhibiting blue nodes and 25.9% exhibiting blue lymphatics. Of identified blue nodes, 70.2% were excised, including 51.5% crossover nodes. Lymphedema occurred in 3 patients, resulting in a BCRL rate of 1.4%. Compared with an historical BCRL incidence of 40.4% following ALND in ethnic minorities, our study reported a significantly lower rate of 8% (p < 0.001). CONCLUSION: The ARM procedure can significantly lower BCRL in ethnic minority groups. The combination of ARM and bioimpedance spectroscopy led to a remarkably low BCRL rate of 1.4%. Notably, none of the patients in our study developed an axillary recurrence at 24-month follow-up. Nevertheless, future studies with larger sample sizes are warranted to better understand the utility of the ARM technique in this population.

Lifetime Health and Economic Burden of Invasive Pneumococcal Diseases Attributable to V116 Serotypes Among Adults in the United States.

INTRODUCTION: This study aimed to estimate and compare the lifetime clinical and economic burden of invasive pneumococcal diseases (IPD) attributable to the serotypes contained in a new 21-valent pneumococcal conjugate vaccine (V116) vs. the 20-valent pneumococcal conjugate vaccine (PCV20) among adults aged 18 years and above in the USA. METHODS: A state-transition Markov model was used to track IPD cases and deaths as well as the associated direct medical costs (in 2023 US dollars) from a US healthcare payer perspective at 3% annual discount rate. The results were summarized for V116, PCV20, and eight unique serotypes contained in V116. A sensitivity analysis was conducted to determine the most influential inputs on the overall total direct lifetime cost. RESULTS: For the total population of US adults aged 18 years and above in 2021 (approx. 258 million residents), the estimated lifetime numbers of cases of IPD, post-meningitis sequelae (PMS), and IPD-related deaths attributable to the serotypes contained in V116 were approximately 1.4 million, 17,608, and 186,200, respectively, with a total discounted lifetime direct cost of $32.6 billion. A substantial proportion (approx. 31%) of those were attributable to the unique eight serotypes. The corresponding estimates for PCV20 were approximately 35% lower-934,000, 11,500, and 120,000, respectively-with a total discounted direct lifetime cost of $21.9 billion. CONCLUSION: These results show that V116 serotypes (compared to PCV20) are associated with substantially higher clinical and economic burden of IPD. The addition of V116 to vaccination recommendations can help to reduce the residual burden of IPD in US adults.

The biphasic activity of autophagy and heat shock protein response in peripheral blood mononuclear cells following acute resistance exercise in resistance-trained males.

PURPOSE: Autophagy and heat shock protein (HSP) response are proteostatic systems involved in the acute and adaptive responses to exercise. These systems may upregulate sequentially following cellular stress including acute exercise, however, currently few data exist in humans. This study investigated the autophagic and HSP responses to acute intense lower body resistance exercise in peripheral blood mononuclear cells (PBMCs) with and without branched-chain amino acids (BCAA) supplementation. METHODS: Twenty resistance-trained males (22.3 ± 1.5 yr; 175.4 ± .7 cm; 86.4 ± 15.6 kg) performed a bout of intense lower body resistance exercise and markers of autophagy and HSP70 were measured immediately post- (IPE) and 2, 4, 24, 48, and 72 h post-exercise. Prior to resistance exercise, 10 subjects were randomly assigned to BCAA supplementation of 0.22 g/kg/d for 5 days pre-exercise and up to 72 h following exercise while the other 10 subjects consumed a placebo (PLCB). RESULTS: There were no difference in autophagy markers or HSP70 expression between BCAA and PLCB groups. LC3II protein expression was significantly lower 2 and 4 h post-exercise compared to pre-exercise. LC3II: I ratio was not different at any time point compared to pre-exercise. Protein expression of p62 was lower IPE, 2, and 4 h post-exercise and elevated 24 h post-exercise. HSP70 expression was elevated 48 and 72 h post-exercise. CONCLUSIONS: Autophagy and HSP70 are upregulated in PBMCs following intense resistance exercise with autophagy increasing initially post-exercise and HSP response in the latter period. Moreover, BCAA supplementation did not affect this response.

Risk factors associated with severe COVID-19 outcomes in Jamaica: a cross-sectional study of national surveillance data.

Objectives: To describe the characteristics and outcomes of COVID-19 cases in Jamaica and to explore the risk factors associated with severe COVID-19 from 9 March to 31 December 2020. Methods: A cross-sectional analysis of national surveillance data was conducted using confirmed COVID-19 cases in Jamaica. Definitions of a confirmed case, disease severity, and death were based on World Health Organization guidelines. Chi-square and Fisher exact tests were used to determine association with outcomes. Logistic regression models were used to determine predictors of severe COVID-19. Results: This analysis included 12 169 cases of COVID-19 (median age, 36 years; 6 744 females [ 55.4%]) of which 512 cases (4.2%) presented with severe disease, and of those, 318 patients (62.1%) died (median age at death, 71.5 years). Severe disease was associated with being male (OR 1.4; 95% CI, 1.2-1.7) and 40 years or older (OR, 6.5; 95% CI, 5.1-8.2). COVID-19 death was also associated with being male (OR, 1.4; 95% CI, 1.1-1.7), age 40 years or older (OR, 17.9; 95% CI, 11.6-27.7), and in the Western versus South East Health Region (OR 1.7; 95% CI, 1.2-2.3). Conclusions: The findings of this cross-sectional analysis indicate that confirmed cases of COVID-19 in Jamaica were more likely to be female and younger individuals, whereas COVID-19 deaths occurred more frequently in males and older individuals. There is increased risk of poor COVID-19 outcomes beginning at age 40, with males disproportionately affected. COVID-19 death also varied by geographic region. This evidence could be useful to other countries with similar settings and to policymakers charged with managing outbreaks and health.

Oncoplastic breast-conserving surgery (OBCS) vs. mastectomy with reconstruction: a comparison of outcomes in an underserved population.

Background: Oncoplastic breast-conserving surgery (OBCS) has demonstrated superior cosmetic outcomes to traditional breast-conserving surgery (BCS) while maintaining oncologic safety. While prior studies have compared OBCS to mastectomy, there is a scarcity of literature on the impact of social determinants of health on outcomes. Furthermore, although traditionally tumors larger than 5 cm and multifocal disease were treated with mastectomy, the literature has now shown OBCS to be safe in treating such disease. As a result, patients with large or multifocal tumors could be eligible for both mastectomy and OBCS, which prompts the need for comparison between the two. Thus, the aim of our study was to compare OBCS and mastectomy with reconstruction using BREAST-Q and oncologic outcome measures, as well as stratify these outcomes based on race, ethnicity, and body mass index (BMI). Methods: A retrospective chart review was performed for 57 patients treated with OBCS and 204 patients treated with mastectomy with reconstruction from 2015 to 2021. Variables including age, race, ethnicity, BMI, insurance status, surgery type, pathology, recurrence, and complications were recorded. Patient-reported outcomes (PROs) were recorded using BREAST-Q pre- and post-operatively. Results: Despite having a higher BMI (P<0.001), OBCS yielded higher "satisfaction with breast" and "satisfaction with outcome" than mastectomy (P=0.02 and P=0.02, respectively). When stratified by race, there were no statistical differences in the PROs between the two surgeries for Hispanic nor African American patients. OBCS had a significantly lower rate of infection and fewer additional surgeries than mastectomy (P=0.004 and P<0.001, respectively). There were no differences in positive margin rate or recurrence rate between the groups. Conclusions: In our study, OBCS yielded better PROs than mastectomy while maintaining oncologic safety and resulting in fewer surgeries and complications. These excellent outcomes in a majority non-Caucasian cohort support the utilization of OBCS for underserved, minority populations. Larger studies evaluating PROs in diverse and uninsured groups are needed to reinforce these conclusions.

Descriptive Epidemiology of Pathogens Associated with Acute Respiratory Infection in a Community-Based Study of K-12 School Children (2015-2023).

School-based outbreaks often precede increased incidence of acute respiratory infections in the greater community. We conducted acute respiratory infection surveillance among children to elucidate commonly detected pathogens in school settings and their unique characteristics and epidemiological patterns. The ORegon CHild Absenteeism due to Respiratory Disease Study (ORCHARDS) is a longitudinal, laboratory-supported, school-based, acute respiratory illness (ARI) surveillance study designed to evaluate the utility of cause-specific student absenteeism monitoring for early detection of increased activity of influenza and other respiratory viruses in schools from kindergarten through 12th grade. Eligible participants with ARIs provided demographic, epidemiologic, and symptom data, along with a nasal swab or oropharyngeal specimen. Multipathogen testing using reverse-transcription polymerase chain reaction (RT-PCR) was performed on all specimens for 18 respiratory viruses and 2 atypical bacterial pathogens (Chlamydia pneumoniae and Mycoplasma pneumoniae). Between 5 January 2015 and 9 June 2023, 3498 children participated. Pathogens were detected in 2455 of 3498 (70%) specimens. Rhinovirus/enteroviruses (36%) and influenza viruses A/B (35%) were most commonly identified in positive specimens. Rhinovirus/enteroviruses and parainfluenza viruses occurred early in the academic year, followed by seasonal coronaviruses, RSV, influenza viruses A/B, and human metapneumovirus. Since its emergence in 2020, SARS-CoV-2 was detected year-round and had a higher median age than the other pathogens. A better understanding of the etiologies, presentations, and patterns of pediatric acute respiratory infections can help inform medical and public health system responses.

Sirolimus potentiated angioedema: A case report and review of the literature.

Introduction: In the realm of organ transplantation, particularly heart transplantation, angioedema presents a significant challenge. This clinical condition ranges from minor facial edema to life-threatening swelling of vital structures. Its multifactorial etiology involves various factors and mechanisms, including C1 esterase inhibitor deficiency, food allergen hypersensitivity, and adverse drug reactions, notably involving angiotensin-converting enzyme (ACE) inhibitors and mechanistic target of rapamycin inhibitors (mTOR-Is). We present a rare case of sirolimus potentiated angioedema in a patient with long-standing ACE inhibitor therapy. Case: A 52-year-old male with a history of heart transplant developed severe upper and lower lip edema. The patient had been on Lisinopril without any adverse events. However, sirolimus was recently added to his drug regimen. Sirolimus potentiated angioedema was suspected. Intervention: Intravenous methylprednisolone, famotidine, and diphenhydramine were initiated, and both lisinopril and sirolimus were discontinued. The patient showed improvement and was discharged with oral antihistamines. Lessons: Transplant physicians should be aware of the life-threatening interaction between ACE inhibitors and mTOR-Is like sirolimus. Consideration should be given to switching from an ACE inhibitor to an angiotensin-receptor blocker when initiating patients on mTOR-Is.

Sexual Exposures Associated With Mpox Infection: California, November 2022 to June 2023.

BACKGROUND: Exposures associated with mpox infection remain imperfectly understood. METHODS: We conducted a case-control study enrolling participants who received molecular tests for mpox/orthopoxvirus in California from November 2022 through June 2023. We collected data on behaviors during a 21-day risk period before symptom onset or testing among mpox case patients and test-negative controls. RESULTS: Thirteen of 54 case patients (24.1%) and 5 of 117 controls (4.3%) reported sexual exposure to individuals they identified as potential mpox case patients ("index contacts"; odds ratio [OR], 7.7 [95% confidence interval (CI), 2.5-19.3] relative to individuals who did not report exposure to potential mpox case patients). Among these participants, 10 of 13 case patients (76.9%) and 2 of 5 controls (40.0%) reported that their index contacts were not experiencing symptoms visible to participants during sex (OR, 14.9 [95% CI, 3.6-101.8]). Only 3 of 54 case patients (5.6%) reported exposure to symptomatic index contacts. Case patients reported more anal/vaginal sex partners than did controls (adjusted OR, 2.2 [95% CI, 1.0-4.8] for 2-3 partners and 3.8 [1.7-8.8] for ≥4 partners). Male case patients with penile lesions more commonly reported insertive anal/vaginal sex than those without penile lesions (adjusted OR, 9.3 [95% CI, 1.6-54.8]). Case patients with anorectal lesions more commonly reported receptive anal sex than those without anorectal lesions (adjusted OR, 14.4 [95% CI, 1.0-207.3]). CONCLUSIONS: Sexual exposure to contacts known or suspected to have experienced mpox was associated with increased risk of infection, often when index contacts lacked apparent symptoms. Exposure to more sex partners, including those whom participants did not identify as index contacts, was associated with increased risk of infection in a site-specific manner. While participants' assessment of symptoms in partners may be imperfect, these findings suggest that individuals without visibly prominent mpox symptoms transmit infection.

Blenderized food tube feeding in very young pediatric patients with special healthcare needs.

BACKGROUND: Up to 85% of children with severe developmental disabilities have feeding disorders and require enteral tube feeding. Many caregivers desire blenderized tube feeding (BTF) instead of commercial formula (CF) for their child, citing a desire for a more physiologic feeding, to reduce gastrointestinal (GI) symptoms and/or promote oral intake. METHODS: In this retrospective, single-center study, medical records (n = 34) of very young children (aged ≤36 months) with severe developmental disabilities were reviewed. Comparisons of growth parameters, GI symptoms, oral feeding, and GI medication use were made between the initial introduction of BTF and again at the last patient encounter when the children aged out of the program. RESULTS: Of the 34 charts reviewed (16 male and 18 female patients), comparisons between baseline BTF introduction and the last patient encounter indicated reductions in adverse GI symptoms, significant GI medication reduction (P = 0.000), increased oral food intake, and nonsignificant improvements in growth parameters. These positive outcomes were realized whether children received full or partial BTF or type of BTF formulation. CONCLUSION: Consistent with similar research studies, transitioning very young children with significant special healthcare needs from CF to BTF resulted in improvement in GI symptoms, reduced need for GI medications, supported growth goals, and contributed to improved oral feeding.

Influence of polarized light, disruptive visual patterns, and chemical cues on oviposition in the aquatic midge, Chironomus riparius (Diptera: Chironomidae).

Chironomid nonbiting midges are common in many waterbodies, occurring at high densities in sediment and also when flying adults emerge. Although important for food webs and ecosystem processes, the mass emergences of chironomid adults make some species nuisance pests. As part of an effort to develop "push-pull" strategies for managing midge populations, we investigated the importance of visual and chemical cues used by gravid females when selecting sites for oviposition. Field and laboratory oviposition choice tests with Chironomus riparius (Meigen) were used to assess the attractiveness of dark container colors and polarized light for females seeking water for egg laying. Females were not sensitive to increased intensity of polarized light, but they laid fewer eggs in containers with white color above the water's edge but black below the surface. A disruptive pattern of vertical black and white stripes at the water's edge reduced egg laying to a similar degree as white. To investigate the importance of olfactory or gustatory cues in oviposition decisions, we tested 3 potential chemical repellents (damaged larvae simulating predator presence, azadiractin, and picaridin) and 5 potential attractants (a tannin-molasses mixture, leaf detritus, live Hydrilla plants, periphyton, and fermented alfalfa infusions used to bait mosquito oviposition traps). Chemical cues appeared to play a weak role, if any, in oviposition choices. Onlyazadiractin (0.02 and 0.11 ppm) reduced the number of egg ropes deposited, but the mechanism may have been from mechanical trapping and drowning, not deterrence.

RESUMEN Objetivos. Describir las características y los resultados de los casos de COVID-19 en Jamaica y explorar los factores de riesgo asociados a la COVID-19 grave desde el 9 de marzo hasta el 31 de diciembre del 2020. Métodos. Se realizó un análisis transversal de datos nacionales de vigilancia a partir de los casos confirmados de COVID-19 en Jamaica. Las definiciones de caso confirmado, gravedad de la enfermedad y muerte se basaron en las directrices de la Organización Mundial de la Salud. Para determinar la asociación con los criterios de valoración se utilizó la prueba de χ2 y la prueba exacta de Fisher. Se usaron modelos de regresión logística para determinar los factores predictivos de la COVID-19 grave. Resultados. Se incluyeron en el análisis 12 169 casos de COVID-19 (mediana de edad, 36 años; 6 744 mujeres [55,4%]), de los que 512 (4,2%) fueron de enfermedad grave. De estos pacientes, 318 (62,1%) fallecieron (mediana de edad al morir, 71,5 años). Se observó una asociación de la enfermedad grave con el sexo masculino (OR de 1,4; IC del 95 %, 1,2-1,7) y con la edad igual o superior a 40 años (OR de 6,5; IC del 95 %, 5,1-8,2). La muerte por COVID-19 también mostró una asociación con el sexo masculino (OR de 1,4; IC del 95%, 1,1-1,7), con la edad igual o superior a 40 años (OR de 17,9; IC del 95%, 11,6-27,7) y con la Región de Atención de Salud Occidental en comparación con la Sudoriental (OR de 1,7; IC del 95%, 1,2-2,3). Conclusiones. Los resultados de este análisis transversal indican que los casos confirmados de COVID-19 en Jamaica correspondieron una mayor probabilidad a mujeres y personas más jóvenes, mientras que las muertes por COVID-19 fueron más frecuentes en varones y personas de mayor edad. Hay un mayor riesgo de evolución desfavorable de la COVID-19 a partir de los 40 años, que afecta de manera desproporcionada a los varones. Las muertes por COVID-19 también variaron según la región geográfica. Esta evidencia podría ser de utilidad para otros países con entornos similares y para los responsables de la formulación de políticas en materia de gestión de brotes y salud.

RESUMO Objetivos. Descrever as características e os desfechos dos casos de COVID-19 na Jamaica e explorar os fatores de risco associados à COVID-19 grave de 9 de março a 31 de dezembro de 2020. Métodos. Análise transversal de dados de vigilância nacional usando casos confirmados de COVID-19 na Jamaica. As definições de caso confirmado, gravidade da doença e morte foram baseadas nas recomendações da Organização Mundial da Saúde. Foram usados testes de qui-quadrado e exato de Fisher para determinar a associação com os desfechos. Modelos de regressão logística foram usados para determinar os preditores de COVID-19 grave. Resultados. Esta análise incluiu 12.169 casos de COVID-19 (idade mediana: 36 anos; 6 744 do sexo feminino [55,4%]), dos quais 512 casos (4,2%) apresentaram doença grave; desses, 318 pacientes (62,1%) morreram (idade mediana ao morrer: 71,5 anos). A doença grave estava associada a ser do sexo masculino (razão de chances [RC]: 1,4; intervalo de confiança de 95% [IC 95%]: 1,2-1,7) e ter 40 anos ou mais de idade (RC: 6,5; IC 95%: 5,1-8,2). A morte por COVID-19 também estava associada a ser sexo masculino (RC: 1,4; IC 95%: 1,1-1,7), ter 40 anos ou mais (RC: 17,9; IC 95%: 11,6-27,7) e estar na Região Sanitária Oeste em comparação com a Região Sanitária Sudeste (RC: 1,7; IC 95%: 1,2-2,3). Conclusões. Os achados desta análise transversal indicam que a probabilidade de casos confirmados de COVID-19 na Jamaica era maior em indivíduos do sexo feminino e mais jovens, ao passo que as mortes por COVID-19 ocorreram com mais frequência em indivíduos do sexo masculino e mais velhos. Há um risco maior de resultados desfavoráveis em relação à COVID-19 a partir dos 40 anos, e indivíduos do sexo masculino são desproporcionalmente mais afetados. A morte por COVID-19 também variou de acordo com a região geográfica. Essas evidências podem ser úteis para outros países com cenários semelhantes e para os formuladores de políticas encarregados de manejar surtos e gerenciar a saúde.

Treatment of Mpox with Suspected Tecovirimat Resistance in Immunocompromised Patient, United States, 2022.

Reports of tecovirimat-resistant mpox have emerged after widespread use of antiviral therapy during the 2022 mpox outbreak. Optimal management of patients with persistent infection with or without suspected resistance is yet to be established. We report a successfully treated case of severe mpox in California, USA, that had suspected tecovirimat resistance.

Sodium and potassium consumption in Jamaica: National estimates and associated factors from the Jamaica Health and Lifestyle Survey 2016-2017.

This study aimed to estimate dietary sodium and potassium consumption among Jamaicans and evaluate associations with sociodemographic and clinical characteristics. A cross-sectional study was conducted using data from the Jamaica Health and Lifestyle Survey 2016-2017. Participants were noninstitutionalized Jamaicans aged ≥15 years. Trained staff collected sociodemographic and health data via interviewer-administered questionnaires and spot urine samples. The Pan American Health Organization formula was used to estimate 24-hour urine sodium and potassium excretion. High sodium level was defined as ≥2000 mg/day, and low potassium levels as <3510 mg/day (World Health Organization criteria). Associations between these outcomes and sociodemographic and clinical characteristics were explored using multivariable ANOVA models using log-transformed 24-hour urine sodium and potassium as outcome variables. Analyses included 1009 participants (368 males, 641 females; mean age 48.5 years). The mean sodium excretion was 3582 mg/day (males 3943 mg/day, females 3245 mg/day, P < .001). The mean potassium excretion was 2052 mg/day (males, 2210 mg/day; females, 1904 mg/day; P = .001). The prevalence of high sodium consumption was 66.6% (males 72.8%, females 60.7%, P < .001) and that of low potassium intake was 88.8% (85.1% males, 92.3% females, P < .001). Sodium consumption was inversely associated with older age, higher education, and low glomerular filtration rate but was directly associated with being male, current smoking, and obesity. Overall, males had higher sodium consumption than women, with the effect being larger among hypertensive men. Women with hypertension had lower sodium consumption than nonhypertensive women; however, hypertensive men had higher sodium consumption than nonhypertensive men. Potassium consumption was higher among men, persons with obesity, and those with high total cholesterol but was lower among men with "more than high school" education compared to men with "less than high school" education. We conclude that most Jamaican adults have diets high in sodium and low in potassium. In this study, sodium consumption was directly associated with male sex, obesity, and current smoking but was inversely associated with older age and higher education. High potassium consumption was associated with obesity and high cholesterol levels. These associations should be further explored in longitudinal studies and population-based strategies should be developed to address these cardiovascular risk factors.
