RESUMEN
STUDY OBJECTIVES: This study examined the relationship between naps and cardiovascular disease (CVD) events or death in different age and sex groups. METHODS: A total of 3,069 participants stratified by age (< 65, 65-74, and ≥ 75 years old) and sex, underwent Cox regression analysis to assess nap's impact on CVD risk. Restricted cubic spline plots were used for dose-response relationships. RESULTS: Significant age-stratified interactions were found when exploring the associations between nap frequency or duration and CVD events (Pinteraction = .001, .036, respectively). Individuals younger than 65 years with higher nap frequency or longer nap duration had a significantly increased risk of CVD events (P < .001, P = .001, respectively). The age group of 65-74 years showed significant associations between CVD events and nap frequency or nap duration (P = .017, .016, respectively), together with nap duration and CVD deaths (P = .008). In the subgroup of females aged 65-74, significant associations were found between nap frequency or duration and CVD events (P = .006, .002, respectively). Nap frequency or duration was also significantly associated with CVD deaths (P = .005, .010 respectively). CONCLUSIONS: This study underscores a noteworthy correlation between a higher frequency or longer duration of daytime nap and an increased susceptibility to CVD among individuals aged 65-74 years, particularly in females. However, further research is needed to better understand the underlying mechanisms.

PROBLEM: Pemphigus vulgaris may worsen during pregnancy, leading to both maternal and fetal complications. The relationship between pemphigus vulgaris and pregnancy remains unclear, and the outcomes and treatments of pemphigus vulgaris during pregnancy have not been extensively discussed. METHOD OF STUDY: This article systematically reviews the literature, focusing on the relationship between pemphigus vulgaris and pregnancy. We conducted comprehensive searches in PubMed, Embase, Cochrane Library, and Web of Science databases, identifying 42 studies reporting the disease course, pregnancy outcomes, and management of both pregnancy and pemphigus vulgaris. RESULTS: A total of 57 cases were included in the analysis, categorized into three distinct forms: pemphigus vulgaris onset before pregnancy (n = 33), onset during pregnancy (n = 20), and onset during the postpartum period (n = 4). Fifty four cases reported treatment strategies, among them, 44 cases (81.5%) initially received systemic corticosteroid therapy during pregnancy. Out of these cases, 7 (15.9%) did not achieve successful remission and required alternative treatment approaches. In terms of pregnancy outcomes, 23 out of 62 neonates (37.1%) exhibited skin lesions or tested positive for anti-dsg IgG in their serum, while 16 neonates (25.8%) experienced other complications. CONCLUSIONS: These findings highlight the importance of effectively managing pemphigus vulgaris during pregnancy to ensure optimal outcomes.

BACKGROUND: Previous observational studies reported altered melanoma risks in relation to many potential factors, such as coffee intake, smoking habits and photodamage-related conditions. Considering the susceptibility of epidemiological studies to residual confounders, there remains uncertainty about the actual causal roles of these reported factors in melanoma aetiology. OBJECTIVES: This study aims to investigate the causal association between cutaneous melanoma (CM) and previously reported factors: coffee intake, alcohol consumption, lifetime smoking, socioeconomic status (SES), ease of skin tanning, childhood sunburn and facial ageing, providing insight into its underlying aetiology and preventative strategies. METHODS: We utilized a two-sample MR analysis on data from the largest meta-analysis summary statistics of confirmed cutaneous melanoma including 30,134 patients. Genetic instrumental variables were constructed by identifying single nucleotide polymorphisms (SNPs) that associate with corresponding factors. Inverse variance weighted (IVW) was the primary MR method. For sensitivity and heterogeneity, MR Egger, weighted median, simple mode, weighted mode and MR Egger intercept tests were examined. RESULTS: Cutaneous melanoma risks were found to be elevated in association with a predisposition towards ease of skin tanning (IVW: OR = 2.842, 95% CI 2.468-3.274, p < 0.001) and with childhood sunburn history (IVW: OR = 6.317, 95% CI 4.479-8.909, p < 0.001). Repeated MR after removing potential confounders and outliers demonstrated resolved horizontal pleiotropy and statistically significant results that closely mirrored the initial findings. Other potential factors, such as coffee intake, alcohol consumption, smoking and socioeconomic status (SES), indicated insignificant effects on melanoma risk in the analysis, and therefore, our Mendelian randomization study does not support their roles in modifying melanoma risks. CONCLUSIONS: Our extensive MR analysis provides strong evidence of the causative role of ease of skin tanning and childhood sunburn history in elevating melanoma risk. Curtailing ultraviolet radiation (UVR) exposure may be the single best preventative strategy to reduce melanoma risk.

Purpose: General paresis is a common type of neurosyphilis featuring progressive cognitive deterioration. The lack of a golden standard of diagnosis and its nonspecific clinical manifestations resulted in a high rate of misdiagnoses. This study aims to investigate the clinical, laboratory and radiological presentations of general paresis and enrich its knowledge for timely diagnoses. Patients and methods: The study collected hospitalized patients admitted for general paresis from September 2002 to November 2022. Their socio-demographical and medical status, clinical presentations, cognitive assessments, laboratory and radiographical manifestations and treatment information were collected retrospectively. Results: A total of 20 males and 5 females were included. Patients' ages ranged from 30 to 66 years (average 50.3 years). The average and median time for diagnosing general paresis was 14.1 months and 10.0 months respectively. The most frequent initial symptom is memory deterioration (68.0%). Impaired calculative ability and memory deterioration were the most frequent cognitive anomalies, as found in 50% and 45.4% of subjects during examination. The mean and median scores of MoCA was 16.7 and 17 respectively. Serological tests revealed positive TPPA for all patients and a median RPR titer at 1:64 positive. All CSF samples with TPPA and FTA-ABS results reported positivity. The MRI manifestations of general paresis include patchy or speckled hyperintensities (70.8%) and cerebral atrophy (45.8%). The most common lesioned sites in MRI were the ventricular and paraventricular area (50.0%) and temporal lobes (45.8%). For treatment, penicillin-based anti-syphilitic plans were adopted in 17 patients (68.0%). Conclusion: The clinical features and radiological alternations of general paresis patients often exhibited diverse and nonspecific alternations. However, some specific clinical manifestations and auxiliary examinations can provide meaningful clues for the identification and differential diagnosis of this disease.
RESUMEN
The COVID-19 pandemic has profoundly changed our lives. While healthcare resources were redistributed and mobilized to focus on dealing with the COVID-19 crisis, there have been unmet medical needs of patients with other diseases such as syphilis, weaving an integral but neglected component of the pandemic story. In different countries, the epidemiology of newly reported syphilis underwent diverse changes during the COVID-19 pandemic. Asymptomatic cases experienced the largest decline in number. From the perspective of transmission, on one hand, the implementation of lockdown measures led to a higher degree of abstinence and sex distancing in many countries, thereby reducing the transmission of syphilis. On the other hand, vertical transmission was reported to have increased significantly during COVID-19. Meanwhile, the volume of STI clinic capacity declined, and STI staff were redeployed to facilitate the contact tracing of COVID-19. As a result, many STI centers converted traditional in-person clinical services to telemedicine and self-testing. However, syphilis testing and clinical treatment cannot fully adapt to this conversion. In syphilis diagnosis, COVID-19 infection and vaccination were reported to cause false positivity in syphilis serological tests. Diverse cutaneous manifestations of COVID-19 could resemble the skin lesions in syphilis patients, requiring differential diagnosis from clinicians. As for the post-pandemic years, consequent to service interruptions and diagnosis delays, a surge in the number of confirmed cases of syphilis is expected. The COVID-19 pandemic has also been a meaningful lesson for the control and prevention of infectious diseases. The experience in combating COVID-19 has underscored the importance of maintaining a robust and well-supported medical system for the provision of sexual health services and better healthcare equality even during eras of crisis, not least for syphilis patients.
RESUMEN
Malignant melanoma (MM) is a highly aggressive form of skin cancer with increasing global incidence rates, particularly in developed countries. Variations in the prevalence and quality of care provided to patients with melanoma exist across different regions and across different sex and age. Assessing the global burden of melanoma and evaluating the quality of care can provide valuable insights for developing targeted interventions in certain underperforming regions and improving patient outcomes. This study aimed to systematically analyze the Global Burden of Disease Study from 1990 to 2019 to assess the quality of care for skin malignant melanoma on a global scale. We conducted a comprehensive literature review and extracted data on melanoma incidence, mortality, and disability-adjusted life years (DALYs) from the Global Burden of Disease Study. We incorporated these variables using principal component analysis (PCA) to form an informative single variable of quality of care index (QCI) and analyzed its spatial-temporal variations as well as disparities across age, sex and socio-demographic index (SDI). The overall Quality of Care Index (QCI) for melanoma improved from 82.81 in 1990 to 91.29 in 2019. The QCI score showed a positive correlation with socioeconomic status across regions. Australia ranked highest in QCI (99.96), while Central African Republic, and Kiribati had the lowest scores. China and Saudi Arabia showed significant QCI improvement, while the QCI of the Democratic People's Republic of Korea, Zimbabwe, and Guam decreased from 1990 to 2019. The highest QCI scores were observed in the age groups of 20-39 years old (93.40-94.65). Gender disparities narrowed globally in these three decades, but lower Socio-demographic Index (SDI) regions showed increased gender inequities. Our findings highlighted the spatial-temporal variations in the quality of care of MM as well as its disparities across different SDI levels, age groups and sex. These findings offer valuable insights and guidance for implementing focused interventions and resource allocation to enhance the quality of care and overall outcomes for MM worldwide, especially for underperforming regions.

RESULTS: The MR analysis using two TL GWAS datasets revealed strong and consistent evidence that long TL is causally associated with an increased risk of CM. The analysis of the Codd et al. dataset found that long TL significantly predicted an elevated risk of CM (IVW OR = 2.411, 95% CI 2.092-2.780, P = 8.05E-34). Similarly, the analysis of the Li et al. dataset yielded consistent positive results across all MR methods, providing further robustness to the causal relationship (IVW OR = 2.324, 95% CI 1.516-3.565, P = 1.11E-04). The study provides evidence for a causal association between TL and CM susceptibility, indicating that longer TL increases the risk of developing CM and providing insight into the unique telomere biology in melanoma pathogenesis. Telomere maintenance pathways may be a potential target for preventing and treating CM.

BACKGROUND: Idiopathic inflammatory myopathy (IIM) in pregnancy is uncommon but may result in complications for both mother and the fetus. AIM: In this systematic review, we summarized the current literature investigating outcomes of pregnancy related to the dermatomyositis/polymyositis (DM/PM) process. CONTENT: We searched PubMed, Embase, Cochrane Library, and Web of Science databases and included 61 studies reporting the disease course, pregnancy outcomes, and management of both pregnancy and DM/PM in the final analysis.The specific information of 221 pregnancies was extracted and these pregnancies were divided into three distinct forms: pregnancies after disease onset (n = 159), pregnancies with new disease onset (n = 37), and pregnancies followed by postpartum onset (n = 25). In most cases, DM/PM disease activity remained stable or improved throughout pregnancy (80.2%) and the postpartum period (83.9%). Active DM/PM during pregnancy significantly increased the risk of stillbirth or neonatal death (12% vs. 1%, P = .005) and preterm birth (34.7% vs. 11%, P < .001). The rates of other poor outcomes (total fetal loss, low birth weight, and intrauterine growth retardation) were also increased in pregnancies with active disease. Mainstay treatments for active DM/PM during pregnancy are glucocorticoids and intravenous immunoglobins. IMPLICATIONS: The present results underline the importance of good control of myopathy in optimizing the pregnancy outcomes of women with DM/PM.
