Although asthma has emerged as an important public health problem over recent decades in Latin America, there are limited published data on national hospital admission and mortality rates for asthma from countries in the region.

To analyse trends in asthma hospitalisation and mortality rates in Ecuador over a 19-year period from 2000 to 2018.

Hospital discharge and death certificates listing asthma, as defined in the International Classification of Diseases 10th Revision codes (J45 and J46), were used to analyse time trends in rates of hospital admissions and mortality for asthma. The data were obtained from the Ecuadorian National Institute of Statistics and Census. Crude and age-standardised rates were estimated for the entire population. Additionally, specific rates by sex, age and region were estimated. Nacetylcysteine We used joinpoint analysis to identify national trends.

During 2000-2018, a total of 58 250 hospitalisations and 1328 deaths due to asthma were identified. The average annual rates for hospitalisatt with similar trends elsewhere in the Latin American region. Health registration systems in Latin America need to be improved to provide reliable data for future between and within country comparisons of trends in asthma hospitalisations and deaths.
Our analysis shows a temporal trend of reduction in rates of hospitalisations and deaths attributed to asthma between 2000 and 2018 in Ecuador, consistent with similar trends elsewhere in the Latin American region. Health registration systems in Latin America need to be improved to provide reliable data for future between and within country comparisons of trends in asthma hospitalisations and deaths.
Increasing evidence has suggested that pelvic floor exercises and manual physical therapy may improve premature ejaculation (PE) and erectile dysfunction (ED) in males.

To examine the effects of pelvic floor physical therapy treatment in men suffering from PE and ED.

We searched Google Scholar, PubMed, Medline, PEDro databases from inception till January 2020 applying the following keywords pelvic floor, erectile dysfunction, impotence, physiotherapy, exercises, rehabilitation, and pelvic floor muscle exercises.

The review included 37 papers reporting on PE and ED, of which 5 were randomized controlled trials, 2 meta-analyses, and 4 observational studies. Pelvic floor physical therapy treatment included education and rehabilitation. The rehabilitation part encompassed manual therapy techniques that contribute to the normalization of muscle tone and improvement of muscle relaxation. Moreover, exercises, according to the patients' clinical assessment were presented. Most of the studies reported that by n by physical therapists when evaluating and treating ED and PE and contending with both musculoskeletal dysfunction and behavioral contributions. It is recommended that exercises be monitored and situations involving, that is, hyperactivity/increased tone of the PFMs should be avoided. PFM training is simple, safe, and noninvasive; therefore, it should be a preferred approach in the management of ED and PE. This paper presents narrative reviews with a potential bias that systematic reviews or meta-analyses do not have, however, we strove to be all-encompassing and unbiased. There is a demand for high-quality scientific reviews examining the effectiveness of PFM training, manual therapy, and the rationale of pelvic floor physical therapy, in general, in treating individuals with PE and ED.
Electronic cigarettes (e-cigs) have increased in popularity as a potentially less harmful alternative to tobacco smoking; however, the literature suggests "vaping" can cause endothelial damage, which can adversely affect erectile function. While there is a known link between smoking cigarettes and erectile dysfunction (ED), the effect of e-cigs on erectile function has been understudied.

To review the evidence for e-cig use causing endothelial dysfunction, to explore endothelial dysfunction as a potential mechanism for ED, and to determine if there is literature to support e-cigs as a cause of ED.

A literature review was performed to identify publications pertaining to e-cig consumption and ED. Publications regarding e-cig consumption and vascular or endothelial damage were also included. The search was conducted through PubMed, MEDLINE database, the Cochrane Library Central Search, Web of Science, and Google Scholar. We identified 40+ publications for review, including 6 clinical trials and 3 basic sciarette-Associated Endothelial Damage A Potential Mechanism for Erectile Dysfunction. Sex Med Rev 2021;XXXXX-XXX.
Historically, sexual health research has focused on men who have sex with women (MSW) and most research examining the sexual health of men who have sex with men (MSM) has focused on HIV transmission. Despite a high prevalence of sexual health disorders among MSM, there is limited research that has evaluated the diversity of sexual issues in these patients.

The purpose of this review is to describe the unique sexual behaviors, concerns, and dysfunctions of MSM by evaluating the literature on sexual health in this specific patient population.

A PubMed literature search was conducted through December 2020 to identify all relevant publications related to the sexual health, sexual practices, and sexual dysfunction of MSM. Original research, review articles, and meta-analyses were reviewed, including comparisons of sexual behavior and dysfunction between MSM and non-MSM populations and between gay/bisexual men and heterosexual men. Approximately 150 relevant articles were reviewed and 100 were included in theve Sex With Men. Sex Med Rev 2021;XXXXX-XXX.
MSM have been neglected from sexual medicine research, which translates to disparities in health care. Further research that focuses on the MSM population is necessary to better educate healthcare practitioners so that MSM patients can receive adequate care that is tailored to their specific needs.

Acute myeloid leukemia (AML) is a hematological malignancy originating from myeloid precursor cells, with different cytogenetic abnormalities, genetic mutations and diverse clinical prognoses. We investigated the clinical characteristics, treatment patterns, and outcomes of adult AML patients in Taiwan.

We retrospectively included 3851 patients with AML in the Taiwan Cancer Registry Database from 2011 to 2015. We excluded patients younger than 20 years, with acute promyelocytic leukemia, and with no pathological confirmation.

Among the 3292 patients included, 2179 received induction chemotherapy and 1113 did not, because of older age and higher Charlson comorbidity index (CCI) score. Among the 2179 treated patients, 162 received high-dose cytarabine-based chemotherapy, 1535 received standard-dose cytarabine with anthracyclines, 209 received low-dose cytarabine-based chemotherapy, and 273 received chemotherapy without cytarabine. Patients in the low-dose cytarabine group had the oldest age and highest CCI scores compared with the other groups. In the analysis of overall survival (OS), the median OS of the overall study population was 6.27 months. Treated patients with AML had a longer OS than untreated ones (12.43 months treated vs. 2.03 months not treated; P < .0001). In the multivariate analyses of the treated patients with AML, several factors indicated better prognosis, including receiving standard-dose or high-dose cytarabine, female sex, younger age, lower CCI score, treatment at a medical center, favorable cytogenetic abnormalities, and allogeneic hematopoietic stem cell transplantation.

Our study was a population-based study that illustrates the real-world outcomes of adult patients with AML in Taiwan.
Our study was a population-based study that illustrates the real-world outcomes of adult patients with AML in Taiwan.This study aimed to address the prognostic relevance of CD34+/CD38-/TIM3+ leukemic stem cell (LSC) frequency in patients with acute myeloid leukemia (AML) and its impact on patient outcome. We analyzed the expression of LSC markers (CD34+/CD38-/TIM3+) using flow cytometry in bone marrow samples of 53 AML cases before and after induction chemotherapy. The LSC frequency at diagnosis was significantly higher compared with that postinduction (P less then .001). Patients were categorized into high LSC expressers (≥ median) and low expressers ( less then median). Patients with AML with high number of LSCs at diagnosis had significantly lower induction of remission response (P = .0104), shorter disease-free survival, and shorter overall survival (P less then .001 for both) compared with those with lower LSC count. Cox regression analysis revealed that LSC frequency at diagnosis is an independent prognostic factor in AML. Assessment of LSCs (CD34+/CD38-/TIM3+) at diagnosis is recommended for refining of AML risk stratification.
The COVID-19 pandemic originated in China and within about 4 months affected individuals all over the world. One of the limitations to the management of the COVID-19 is the diagnostic imaging to evaluate lung impairment and the patients' clinical evolution, mainly, in more severe cases that require admission into the intensive care unit. Among image examinations, lung ultrasound (LU) might be a useful tool to employ in the treatment of such patients.

A survey was carried out on PubMed to locate studies using the descriptors ((Lung ultrasound OR ultrasound OR lung ultrasonography OR lung US) AND (coronavirus disease-19 OR coronavirus disease OR corona virus OR COVID-19 OR COVID19 OR SARS-CoV-2)). The period covered by the search was November 2019 to October 2020 and the papers selected reported LU in COVID-19.

Forty-three studies were selected to produce this systematic review. The main LU findings referred to the presence of focal, multifocal and/or confluent B lines and the presence of pleural irregularities.

The use of LU in the evaluation of patients with COVID-19 should be encouraged due to its intrinsic characteristics; a low cost, radiation free, practical method, with easy to sanitize equipment, which facilitates structural evaluation of lung damage caused by SARS-CoV-2. With the increase in the number of studies and the use of ultrasound scans, LU has been shown as a useful tool to evaluate progression, therapeutic response and follow-up of pulmonary disease in the patients with COVID-19.

Basic studies suggest that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can affect chronic rhinosinusitis (CRS), but there is unclear real-world evidence regarding the association of underlying CRS with the risk for SARS-CoV-2 infection and severe coronavirus disease 19 (COVID-19).

We aimed to determine whether CRS is associated with increased risk for SARS-CoV-2 infection and severe COVID-19.

Altogether, 219,959 adult patients who tested forSARS-CoV-2 in South Korea from January 1 to May 15, 2020 (excluding self-referral) were identified in this nested case-control study with propensity score matching. Data on SARS-CoV-2 test results and COVID-19 worsened outcomes (ie, the need for oxygen therapy, intensive care, or mechanical ventilation, and death) were obtained from the Health Insurance Review and Assessment Service of Korea.

In this matched cohort, 380 of 12,217 patients with CRS (3.1%) tested positive for SARS-CoV-2 infection, compared with 310 patients without CRS (2.5%; adjusted odds ratio=1.
