RESUMO

Racial and ethnic identities, largely understood as social rather than biologic constructs, may impact risk for acquiring infectious diseases, including fungal infections. Risk factors may include genetic and immunologic differences such as aberrations in host immune response, host polymorphisms, and epigenomic factors stemming from environmental exposures and underlying social determinants of health. In addition, certain racial and ethnic groups may be predisposed to diseases that increase risk for fungal infections, as well as disparities in healthcare access and health insurance. In this review, we analyzed racial and ethnic identities as risk factors for acquiring fungal infections, as well as race and ethnicity as they relate to risk for severe disease from fungal infections. Risk factors for invasive mold infections such as aspergillosis largely appear related to environmental differences and underlying social determinants of health, although immunologic aberrations and genetic polymorphisms may contribute in some circumstances. Although black and African American individuals appear to be at high risk for superficial and invasive Candida infections and cryptococcosis, the reasons for this are unclear and may be related to underling social determinants of health, disparities in access to healthcare, and other socioeconomic disparities. Risk factors for all the endemic fungi are likely largely related to underlying social determinants of health, socioeconomic, and health disparities, although immunologic mechanisms likely play a role as well, particularly in disseminated coccidioidomycosis.

RESUMO

PURPOSE: To examine the association of a traditional Mexican diet score with risk of total, breast, and colorectal cancer among women of Mexican ethnic descent in the Women's Health Initiative (WHI). METHODS: Participants were WHI enrollees who self-identified as being of Mexican descent. Data from food frequency questionnaires self-administered at study baseline were used to calculate the MexD score, with higher scores indicating greater adherence to an a priori-defined traditional Mexican diet (high in dietary fiber, vegetables, and legumes). Incident cancers were self-reported by participants from 1993 to 2020 and adjudicated by trained physicians. We used multivariable-adjusted Cox proportional hazards models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). RESULTS: Among 2,343 Mexican descent women (median baseline age: 59 years), a total of 270 cancers (88 breast, 37 colorectal) occurred during a mean follow-up of 14.4 years. The highest tertile of MexD score was associated with a lower risk of all-cancer incidence (HR: 0.67; 95% CI 0.49-0.91; p-trend: 0.01) and colorectal cancer (HR: 0.38; 95% CI 0.14-0.998; p-trend < 0.05), with each unit increase in the MexD score associated with a 6% lower risk of all-cancer incidence (HR: 0.94; 95% CI 0.88-0.99). There was no statistically significant association with risk of breast cancer. CONCLUSION: Consumption of a traditional Mexican diet was associated with a significantly lower risk of all-cancer incidence and colorectal cancer. Confirmation of these findings in future studies is important, given the prevalence of colorectal cancer and a growing U.S. population of women of Mexican descent.

RESUMO

OBJECTIVE/BACKGROUND: Our study analyzed the relationship between two polypharmacy scores (addition of chronic prescribed drugs [ACPDs] and Rx-Risk Comorbidity Index) and survival in patients with an intact abdominal aortic and/or common iliac aneurysm (AAA). METHODS: Consecutive retrospective, single-center cohort of patients attended for an intact AAA with indication for repair from 2008 to 2021. Demographic data, Charlson Comorbidity Index, AAA treatment, ACPD, and Rx-Risk polypharmacy scores were recorded at baseline. Main outcomes were the 5-year and long-term survival rates. The statistical analysis included Cox regression, area under the curve, and continuous net reclassification index. RESULTS: A total of 424 patients with AAA were evaluated (median age: 76 years; 92.2% male, median Charlson index 2), of whom 314 (74.1%) underwent intervention (80% endovascular and 20% open) and 110 (25.9%) did not. During follow-up (mean 4.6 years), 245 patients (57.8%) died, with 1-month, 1-year, and 5-year survival rates of 98.1%, 86.3%, and 52.7%, respectively. ACPD and Rx-Risk indices (median [interquartile range]: 6 [4-9] and 3 [0-5], respectively) were significantly and linearly associated (P < .001) with survival, with the best cutoff points at 5 and 0, respectively. An ACPD >5 (patients with >5 chronically prescribed drugs at baseline) and an Rx-Risk >0 were associated with a 45.2% (P = .038) and 102% (P = .002) increase in 5-year mortality, respectively, after adjustment for age, sex, Charlson index, and type of AAA treatment. Both polypharmacy indices improved significantly the discriminative power of the Charlson Comorbidity Index in predicting survival. CONCLUSIONS: Both ACPD and Rx-Risk polypharmacy scores are independently related to survival among patients with an intact AAA and indication for repair. Their behavior is similar, so the simple ACPD >5 appears to be sufficient to identify patients with lower survival rates.

RESUMO

INTRODUCTION: The COVID-19 pandemic created difficulties in access to care. There was also increased penetrating trauma in adults, which has been attributed to factors including increased firearm sales and social isolation. However, less is known about the relationship between the pandemic and pediatric trauma patients (PTPs). This study aimed to investigate the national incidence of penetrating trauma in PTPs, hypothesizing a higher rate with onset of the pandemic. We additionally hypothesized increased risk of complications and death in penetrating PTPs after the pandemic versus prepandemic. METHODS: We included all PTPs (aged ≤17-years-old) from the 2017-2020 Trauma Quality Improvement Program database, dividing the dataset into two eras: prepandemic (2017-2019) and pandemic (2020). We performed subset analyses of the pandemic and prepandemic penetrating PTPs. Bivariate analyses and a multivariable logistic regression analysis were performed. RESULTS: Of the 474,524 PTPs, 123,804 (26.1%) were from the pandemic year. The pandemic era had increased stab wounds (3.3% versus 2.8%, P > 0.001) and gunshot wounds (5.5% versus 4.0%, P < 0.001) compared to the prepandemic era. Among penetrating PTPs, the rates and associated risk of in-hospital complications (2.6% versus 2.8%, P = 0.23) (odds ratio 0.90, confidence interval 0.79-1.02, P = 0.11) and mortality (4.9% versus 5.0%, P = 0.58) (odds ratio 0.90, confidence interval 0.78-1.03, P = 0.12) were similar between time periods. CONCLUSIONS: This national analysis confirms increased penetrating trauma, particularly gunshot wounds in pediatric patients following onset of the COVID-19 pandemic. Despite this increase, there was no elevated risk of death or complications, suggesting that trauma systems adapted to the "dual pandemic" of COVID-19 and firearm violence in the pediatric population.

RESUMO

The accuracy of the classic scores that help stratify the pretest clinical probability of pulmonary embolism (PE) in SARS-CoV-2 infection (COVID-19) is low. Therefore, to estimate the risk of PE in these patients, a new set of guidelines must be established. The recently published CHEDDAR score proposes a new diagnostic strategy to reduce the use of computed tomography pulmonary angiography (CTPA) in non-critically ill SARS-COV-2 patients with suspected PE. According to the nomogram, patients are segregated into low-risk (< 182 points) or high-risk (≥ 182 points) based on the best cut-off value to discard PE in the original cohort. We aimed to externally validate this diagnostic strategy in an independent cohort. We analyzed data from two retrospective cohorts of hospitalized non-critically ill COVID-19 patients who underwent a CTPA due to suspicion for PE. CHEDDAR score was applied. As per the CHEDDAR nomogram, patients were classified as having a low or high clinical pre-test probability. Of the 270 patients included, 69 (25.5%) had PE. Applying the CHEDDAR score, 182 (67.4%) patients could have had PE excluded without imaging. Among 58 patients classified as having high clinical pre-test probability, 39 (67.2%) had PE. Sensitivity, specificity, positive and negative predictive values, and AUC were 56%, 90%, 67%, 85%, and 0.783 (95% CI 0.71-0.85), respectively. We provide external validation of the CHEDDAR score in an independent cohort. Even though the CHEDDAR score showed good discrimination capacity, caution is required in patients classified as having low clinical pre-test probability with a D-dimer value > 3000 ng/mL, and a RALE score ≥ 4.

RESUMO

The application of enzymes in agricultural fields has been little explored. One potential application of fungal lytic enzymes (chitinases, lipases, and proteases) is as an additive to current biopesticides to increase their efficacy and reduce the time of mortality. For this, a screening of lytic overproducer fungi under submerged fermentation with a chemical-defined medium was performed. Then, the enzymatic crude extract (ECE) was concentrated and partially characterized. This characterization consisted of measuring the enzymatic activity (lipase, protease and, chitinase) and determining the enzyme stability after storage at temperatures of - 80, - 20 and, 4 °C. And lastly, the application of these concentrated enzymatic crude extracts (C-ECE) as an enhancer of spores-based fungal biopesticide was proven. Beauveria were not as good producers of lytic enzymes as the strains from Trichoderma and Metarhizium. The isolate M. robertsii Mt015 was selected for the co-production of chitinases and proteases; and the isolate T. harzianum Th180 for co-production of chitinases, lipases, and proteases. The C-ECE of Mt015 had a protease activity of 18.6 ± 1.1 U ml-1, chitinase activity of 0.28 ± 0.01 U ml-1, and no lipase activity. Meanwhile, the C-ECE of Th180 reached a chitinase activity of 0.75 U ml-1, lipase activity of 0.32 U ml-1, and protease activity of 0.24 U ml-1. Finally, an enhancing effect of the enzymatic extracts of M. robertsii (66.7%) and T. harzianum (43.5%) on the efficacy of B. bassiana Bv064 against Diatraea saccharalis larvae was observed. This work demonstrates the non-species-specific enhancing effect of enzymatic extracts on the insecticidal activity of conidial-based biopesticides, which constitutes a contribution to the improvement of biological control agents' performance.

RESUMO

BACKGROUND: Different programs promote healthy ageing through the optimization of intrinsic capacity. However, a major challenge is to assess their sustained effects over time. +AGIL Barcelona, a consolidated multidomain program, aims to optimize older adults' intrinsic capacity through a coordinated approach among primary care, geriatrics and community resources, in agreement with the integrated care for older people (ICOPE) guidelines. We aimed to evaluate the +AGIL Barcelona longitudinal effect on older adults' physical performance. METHODS: All +AGIL Barcelona consecutive participants since 2016 were enrolled. After a comprehensive geriatric assessment, a tailored, multidisciplinary intervention aligned with the ICOPE guidelines is offered. It includes a 10-week boost multicomponent exercise program, nutritional and sleep-hygiene counselling, revision and optimization of pharmacological treatments and screening for cognitive impairment, depression and loneliness. Changes in physical performance after 3 and 6 months were assessed using mixed models including baseline frailty degree, time and all potential significant confounders. RESULTS: We included 194 participants in the analysis (mean age = 81.6 [standard deviation = 5.8], 68% women). An independent, clinically and statistically significant improvement in physical performance (Short Physical Performance Battery [SPPB] test, combining gait speed, strength and balance) was found at 3 months (SPPB mean change: 1.4; 95% CI: 1.1-1.6) and 6 months (SPPB mean change: 1.1; 95% CI 0.8-1.5). Equivalent results were observed for all the SPPB sub-tests. CONCLUSIONS: A coordinated, multidisciplinary and integrated program can benefit older adults' intrinsic capacity. The participants' empowerment and the connection with the available community resources are critical points for a successful intervention.

RESUMO

Baricitinib and imatinib are considered therapies for coronavirus disease 2019 (COVID-19), but their ultimate clinical impact remains to be elucidated, so our objective is to determine whether these kinase inhibitors provide benefit when added to standard care in hospitalized COVID-19 patients. Phase-2, open-label, randomized trial with a pick-the-winner design conducted from September 2020 to June 2021 in a single Spanish center. Hospitalized adults with COVID-19 pneumonia and a symptom duration ≤10 days were assigned to 3 arms: imatinib (400 mg qd, 7 days) plus standard-care, baricitinib (4 mg qd, 7 days) plus standard-care, or standard-care alone. Primary outcome was time to clinical improvement (discharge alive or a reduction of 2 points in an ordinal scale of clinical status) compared on a day-by-day basis to identify differences ≥15% between the most and least favorable groups. Secondary outcomes included oxygenation and ventilatory support requirements, additional therapies administered, all-cause mortality, and safety. One hundred and sixty-five patients analyzed. Predefined criteria for selection of the most advantageous arm were met for baricitinib, but not for imatinib. However, no statistically significant differences were observed in formal analysis, but a trend toward better results in patients receiving baricitinib was found compared to standard care alone (hazard ratio [HR] for clinical improvement: 1.41, 95% confidence intervals [CI]: 0.96-2.06; HR for discontinuing oxygen: 1.46, 95% CI: 0.94-2.28). No differences were found regarding additional therapies administered or safety. Baricitinib plus standard care showed better results for hospitalized COVID-19 patients, being the most advantageous therapeutic strategy among those proposed in this exploratory clinical trial.

RESUMO

INTRODUCTION: Different remote interventions, such as applications (apps), have been used to continue promoting healthy ageing and preventing disability during the COVID-19 pandemic. The growing trend of apps in health is exponential and may facilitate scaling up physical activity prescription. Numerous tools are available, but little is known regarding their appropriateness, validation and recommendation, especially for frail older adults. METHODS: In-house, we developed an application that makes both the Apple app Store and the Google Play Store searchable using topic-related keywords and facilitates the extraction of basic app-information of the search results. The study was aimed at apps available to an English-speaking market. The resulting apps were filtered using various inclusion and exclusion criteria. The resultant apps underwent a more in-depth characterisation and searches for scientific publications on each app website and PubMed. RESULTS: From an initial search result of >2,800 apps, 459 met the initial inclusion criteria. After a more in-depth review of their features, 39 apps remained for possible app in older frail patients. After testing them, 22 apps were excluded. Seventeen apps fit the inclusion and exclusion criteria and were deemed appropriate after peer review. Of these, only one app, Vivifrail, had any type of publication/published evidence. CONCLUSION: Apps can be valuable tool in prescribing exercise for frail older adults living in the community. However, few apps seem useful on a large scale, and there is limited evidence to support their effectiveness. It is important to invest in adapting Information and Communication Technologies to this population group.

RESUMO

BACKGROUND: To evaluate the association between the dietary inflammatory index (DII®) and incident cardiovascular disease (CVD) in Hispanic women from the Women's Health Initiative (WHI), and to determine if body mass index (BMI) interacted with the DII scores. METHODS: Secondary analysis of baseline dietary data and long-term CVD outcomes among 3,469 postmenopausal women who self-identified as Hispanic enrolled in WHI. DII scores were calculated from self-administered food frequency questionnaires. The CVD outcomes included coronary heart disease (CHD) and stroke. Stratified Cox regression models were used to assess the relationship between DII scores and CVD in women with and without obesity. Models were adjusted for age, lifestyle risk factors, known risk factors, and neighborhood socioeconomic status. RESULTS: The incidence of CHD was 3.4 and 2.8% for stroke after a median follow-up of 12.9 years. None of the DIIs were associated with CVD risk in this sample of Hispanic women. BMI interacted with the DII (p < 0.20) and stratified models showed that the associations between the DII and CVD were only significant in women with overweight (p < 0.05). In this group, higher DII scores were associated with a higher risk of CHD (HR 1.27; 95% CI: 1.08, 1.51) and a higher risk of stroke (HR 1.32; 95% CI: 1.07, 1.64). CONCLUSION: Among postmenopausal Hispanic women with overweight, greater adherence to pro-inflammatory diets was associated with higher risk of CVD. Additional research is needed to understand how to promote long-term heart-healthy dietary habits to reduce inflammation and prevent CVD in at-risk Hispanic women.

RESUMO

BACKGROUND: COVID-19 mitigation strategies such as masking, social distancing, avoiding group gatherings, and vaccination uptake are crucial interventions to preventing the spread of COVID-19. At present, COVID-19 data are aggregated and fail to identify subgroup variation in Asian American communities such as Hmong Americans. To understand the acceptance, adoption, and adherence to COVID-19 mitigation behaviors, an investigation of Hmong Americans' contextual and personal characteristics was conducted. METHODS: This study aims to describe COVID-19 mitigation behaviors among Hmong Americans and the contextual and personal characteristics that influence these behaviors. A cross-sectional online survey was conducted from April 8 till June 1, 2021, with Hmong Americans aged 18 and over. Descriptive statistics were used to summarize the overall characteristics and COVID-19 related behaviors of Hmong Americans. Chi-square and Fisher's Exact Test were computed to describe COVID-19 mitigation behaviors by gender and generational status (a marker of acculturation). RESULTS: The sample included 507 participants who completed the survey. A majority of the Hmong American participants in our study reported masking (449/505, 88.9%), social distancing (270/496, 55.3%), avoiding group gatherings (345/505, 68.3%), avoiding public spaces (366/506, 72.3%), and obtaining the COVID-19 vaccination (350/506, 69.2%) to stay safe from COVID-19. Women were more likely to socially distance (P = .005), and avoid family (P = .005), and social gatherings (P = .009) compared to men. Social influence patterns related to mitigation behaviors varied by sex. Men were more likely compared to women to be influenced by Hmong community leaders to participate in family and group gatherings (P = .026), masking (P = .029), social distancing (P = .022), and vaccination uptake (P = .037), whereas healthcare providers and government officials were social influencers for social distancing and masking for women. Patterns of social distancing and group gatherings were also influenced by generational status. CONCLUSION: Contextual and personal characteristics influence COVID-19 mitigation behaviors among English speaking Hmong Americans. These findings have implications for identifying and implementing culturally appropriate health messages, future public health interventions, policy development, and ongoing research with this population.

RESUMO

BACKGROUND: The death of a loved one was a challenge many people faced during the COVID-19 pandemic within the context of extraordinary circumstances and great uncertainty. Grief is an unavoidable part of life, and for most people, feelings of grief decrease naturally over time. However, for some people, grieving can become a particularly painful process with clinical symptoms that may require professional help to resolve. To provide psychological support to people who had lost a loved one during the COVID-19 pandemic, an unguided web-based psychological intervention was developed. OBJECTIVE: The main objective of this study was to evaluate the efficacy of the web-based treatment, Grief COVID (Duelo COVID in Spanish; ITLAB), in reducing clinical symptoms of complicated grief, depression, posttraumatic stress, hopelessness, anxiety, and suicidal risk in adults. The secondary aim was to validate the usability of the self-applied intervention system. METHODS: We used a randomized controlled trial with an intervention group (IG) and a waitlist control group (CG). The groups were assessed 3 times (before beginning the intervention, upon completing the intervention, and 3 months after the intervention). The intervention was delivered on the web in an asynchronous format through the Duelo COVID web page. Participants created an account that could be used on their computers, smartphones, or tablets. The evaluation process was automated as part of the intervention. RESULTS: A total of 114 participants were randomly assigned to the IG or CG and met criteria for inclusion in the study (n=45, 39.5% completed the intervention and n=69, 60.5% completed the waitlist period). Most participants (103/114, 90.4%) were women. The results indicated that the treatment significantly reduced baseline clinical symptoms in the IG for all variables (P<.001 to P=.006), with larger effect sizes for depression, hopelessness, grief, anxiety, and risk of suicide (all effect sizes ≥0.5). The follow-up evaluation showed that symptom reduction was maintained at 3 months after the intervention. The results from the CG showed that participants experienced significantly decreased levels of hopelessness after completing the time on the waitlist (P<.001), but their suicidal risk scores increased. Regarding the usability of the self-applied intervention system, the results indicated a high level of satisfaction with the Grief COVID. CONCLUSIONS: The self-applied web-based intervention Grief COVID was effective in reducing symptoms of anxiety, depression, hopelessness, risk of suicide risk, posttraumatic stress disorder, and complicated grief disorder. Grief COVID was evaluated by the participants, who reported that the system was easy to use. These results affirm the importance of developing additional web-based psychological tools to help reduce clinical symptoms in people experiencing grief because of the loss of a loved one during a pandemic.

RESUMO

The human gut microbiome plays an important role in health, and its initial development is conditioned by many factors, such as feeding. It has also been claimed that this colonization is guided by bacterial populations, the dynamic virome, and transkingdom interactions between host and microbial cells, partially mediated by epigenetic signaling. In this article, we characterized the bacteriome, virome, and smallRNome and their interaction in the meconium and stool samples from infants. Bacterial and viral DNA and RNA were extracted from the meconium and stool samples of 2- to 4-month-old milk-fed infants. The bacteriome, DNA and RNA virome, and smallRNome were assessed using 16S rRNA V4 sequencing, viral enrichment sequencing, and small RNA sequencing protocols, respectively. Data pathway analysis and integration were performed using the R package mixOmics. Our findings showed that the bacteriome differed among the three groups, while the virome and smallRNome presented significant differences, mainly between the meconium and stool of milk-fed infants. The gut environment is rapidly acquired after birth, and it is highly adaptable due to the interaction of environmental factors. Additionally, transkingdom interactions between viruses and bacteria can influence host and smallRNome profiles. However, virome characterization has several protocol limitations that must be considered.

RESUMO

HELLP syndrome (HS), a low-incidence condition of uncertain pathogenesis associated with pregnancy hypertensive syndromes, is characterized by hemolysis, elevated liver enzymes and low platelet count. Ruptured subcapsular liver hematoma complicated with hemoperitoneum is an uncommon but very serious condition where early recognition and multidisciplinary management are key to reduce its associated maternal, infant mortality rate. Symptoms are nonspecific, characterized by por epigastric pain, nausea and vomiting; clinical suspicion and appropriate imaging studies are of crucial importance. We report the case of a 36-year-old primiparous woman at 39 weeks of gestation. She was admitted for early membrane rupture, with delivery complicated by retained placenta. During the immediate puerperium she had blood pressure > 140/90 mmHg, epigastric pain and vomiting, which required respiratory and hemodynamic support. An exploratory laparotomy was performed that revealed a massive hemoperitoneum as well as CR in the RLL with multifocal active bleeding. The left liver lobe was macroscopically normal. The patient underwent hemoperitoneum drainage and hepatic packing (HP); biopsy findings were consistent with necrosis. Polytransfusion was initiated with blood products and antihemorrhagic agents.

RESUMO

We have demonstrated that the catalytic and enantioselective vinylcyclopropane-cyclopentene rearrangement can be carried out on (vinylcyclopropyl)acetaldehydes through activation via enamine intermediates. The reaction makes use of racemic starting materials that, upon ring opening facilitated by the catalytic generation of a donor-acceptor cyclopropane, deliver an acyclic iminium ion/dienolate intermediate in which all stereochemical information has been deleted. The final cyclization step forms the rearrangement product, showing that chirality transfer from the catalyst to the final compound is highly effective and leads to the stereocontrolled formation of a variety of structurally different cyclopentenes.

RESUMO

Background: The objective was to report acute toxicity and quality of life in prostate cancer patients treated with definitive hypofractionated pelvic radiation therapy. Materials and methods: Patients were designated candidates for hypofractionated pelvic radiation therapy if biopsy or imaging studies evidenced unfavorable intermediate-risk, high-risk or node-positive disease. Patients were treated using a regimen of 44 Gy to the nodal areas and simultaneous integrated boost of 60 Gy to the prostate in 20 fractions with CBCT-based imaging and volumetric arc therapy (VMAT). Patient data was obtained retrospectively; acute gastrointestinal (GI) and genitourinary (GU) toxicity was classified per Common Terminology Criteria for Adverse Events (CTCAE) v5.0 and obtained from clinical records. Quality of life was surveyed via phone call using the European Organization for Research and Treatment of Cancer (EORTC) questionnaire QLQ-PR25. Results: 78 patients were treated between May and December 2021. 83.33% of patients had high-risk disease, 16.67% had intermediate-risk disease, and 34.62% patients had node-positive disease. Median follow-up was 10.6 months. No patients presented acute grade >3 GI toxicity, and one patient presented grade 3 GU toxicity. 25.64% patients presented acute G2 GI toxicity and 17.95% patients presented acute G2 GU toxicity. 60.26% of patients responded to the EORTC-PR25 questionnaire. Mean scores for symptom scales were 11.26, 4.96 and 9.57 for Urinary Symptoms, Bowel Symptoms and Hormonal Treatment-Related Symptoms; mean scores for Sexual Activity and Functioning were 19.86 and 31.08, respectively. Conclusion: Definitive hypofractionated pelvic radiation therapy has an acceptable acute toxicity and QoL profile in this series of patients, although longer follow-up is needed to properly evaluate short and long-term toxicity. Further follow-up and patient recruitment is ongoing.

RESUMO

Studies have suggested that adults with gallbladder disease have increased risk of type 2 diabetes. This prospective cohort study assessed the risk of type 2 diabetes in postmenopausal women with gallbladder disease. Data from women enrolled in the Women's Health Initiative from 1993 to 2005, aged 50-79 years (mean = 63.2; standard deviation, 7.2), were analyzed. Cox proportional hazards regression models were used to estimate the risk of type 2 diabetes associated with gallbladder disease. There were 8,896 new cases of type 2 diabetes after 1,025,486 person-years of follow-up. Gallbladder disease was significantly associated with type 2 diabetes (hazard ratio = 1.52; 95% confidence interval (CI): 1.38,1.67). The observed risk of type 2 diabetes in women with both gallbladder disease and central obesity was 37% higher than expected (relative excess risk due to interaction = 0.37, 95% CI: 0.11,0.63) on the additive scale. The hazard ratios for type 2 diabetes associated with gallbladder disease were 1.25 (95% CI: 1.19,1.32) and 1.48 (95% CI: 1.34,1.63) in women with and without central obesity, respectively, on the multiplicative scale. Results of this study support further studies to determine whether interventions in older women with gallbladder disease would reduce type 2 diabetes risk, especially among those with central obesity. Future research should examine the pathophysiological basis of the association between gallbladder disease and type 2 diabetes.

RESUMO

Coronavirus disease 2019 (COVID-19) infection in elderly patients is more aggressive and treatments have shown limited efficacy. Our objective is to describe the clinical course and to analyze the prognostic factors associated with a higher risk of mortality of a cohort of patients older than 80 years. In addition, we assess the efficacy of immunosuppressive treatments in this population. We analyzed the data from 163 patients older than 80 years admitted to our institution for COVID-19, during March and April 2020. A Lasso regression model and subsequent multivariate Cox regression were performed to select variables predictive of death. We evaluated the efficacy of immunomodulatory therapy in three cohorts using adjusted survival analysis. The mortality rate was 43%. The mean age was 85.2 years. The disease was considered severe in 76.1% of the cases. Lasso regression and multivariate Cox regression indicated that factors correlated with hospital mortality were: age (hazard ratio [HR] 1.12, 95% confidence interval [CI]: 1.03-1.22), alcohol consumption (HR 3.15, 95% CI: 1.27-7.84), CRP > 10 mg/dL (HR 2.67, 95% CI: 1.36-5.24), and oxygen support with Venturi Mask (HR 6.37, 95% CI: 2.18-18.62) or reservoir (HR 7.87, 95% CI: 3.37-18.38). Previous treatment with antiplatelets was the only protective factor (HR 0.47, 95% CI: 0.23-0.96). In the adjusted treatment efficacy analysis, we found benefit in the combined use of tocilizumab (TCZ) and corticosteroids (CS) (HR 0.09, 95% CI: 0.01-0.74) compared to standard treatment, with no benefit of CS alone (HR 0.95, 95% CI: 0.53-1.71). Hospitalized elderly patients suffer from a severe and often fatal form of COVID-19 disease. In this regard, several parameters might identify high-risk patients upon admission. Combined use of TCZ and CS could improve survival.

RESUMO

BACKGROUND: Depressive symptoms are associated with age-related cognitive impairment, but the relative risk of specific subtypes of mild cognitive impairment (MCI) conferred by depressive symptoms is unclear. The purpose of this exploratory study was to determine the longitudinal association between baseline depressive symptoms and incident cases of MCI subtypes (amnestic vs. non-amnestic) and probable dementia (PD) (Alzheimer's disease, vascular, mixed) among postmenopausal women. METHODS: Depressive symptoms were assessed at study baseline using an 8-item Burnam algorithm in 7043 postmenopausal women who participated in the Women's Health Initiative Memory Study (WHIMS) and the WHIMS-Epidemiology of Cognitive Health Outcomes (WHIMS-ECHO) extension study. During the median 9.4-year follow-up interval, the presence of MCI and PD was classified by a central adjudication committee. Classification of participants by MCI subtype (amnestic single and multi-domain, non-amnestic single and multi-domain) was done algorithmically based on established criteria using data from annual cognitive testing. RESULTS: At baseline, 557 women (7.9%) had clinically significant depressive symptoms based on Burnam algorithm cut-point of 0.06. Depressive symptoms at baseline were associated with an increased risk of incident amnestic MCI (hazard ratio [HR] = 1.91, 95% confidence interval [CI] 1.32-2.78, p < 0.0001), but not non-amnestic MCI (HR = 1.39, 95% CI 0.91-2.14, p = 0.13) after controlling for demographic factors. This relationship between depressive symptoms and amnestic MCI remained consistent after controlling for lifestyle variables, cardiovascular risk factors, antidepressant use, and history of hormone therapy. There were no significant associations between depressive symptoms and incidence of PD. CONCLUSION: Depressive symptoms at baseline among postmenopausal older women are associated with higher incidence of amnestic MCI, suggesting that they may be an independent risk factor or part of the early prodrome of dementia.

RESUMO

INTRODUCTION: Most cancers occur in older individuals, who are more vulnerable due to functional impairment, multiple comorbidities, cognitive impairment, and lack of socio-familial support. These can undermine patients' sense of dignity. This study seeks to compare dignity scores in older patients with advanced cancer on sociodemographic and clinical variables and analyze the predictive value of anxiety, depression, functional limitations, and social support on dignity scores. METHODS: A prospective, multicenter, observational study conducted with participation of 15 hospitals in Spain from February 2020 to October 2021. Patients with newly-diagnosed, advanced cancer completed the dignity (PPDS), anxiety and depression (BSI), Social Support (Duke-UNC-11), and functional limitations (EORTC-C30) scales. Lineal regression analyses explored the effects of anxiety, depression, functional status, and social support on dignity, adjusting for sociodemographic and clinical variables. RESULTS: A total of 180 subjects participated in this study. The results of the correlation analysis revealed that dignity correlated negatively with anxiety, depression, and sex, and positively with social support, functional status, and longer estimated survival. Thus, women, and more anxious and depressed individuals scored lower on the dignity scale, whereas patients with more social support, fewer functional limitations, and longer estimated survival scored higher. CONCLUSION: In conclusion, being female, having a lower educational level, lower estimated survival, depression, anxiety, less social support, and limited functionality are correlated with less dignity in the elderly with advanced cancer. It is a priority to manage both physical and psychological symptoms in patients with unresectable advanced cancer to mitigate psychological distress and increase their sense of dignity.
