RESUMO

INTRODUCTION: Sexual dysfunction (SD) and allergic disease are common health concerns worldwide and bear a potential relationship. This scoping review is conducted to analyze the currently available data regarding the associations between these two health issues. METHODS: A comprehensive literature search was performed in the databases of PubMed, MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science to retrieve studies that were published before January 2023. A narrative synthesis was conducted to analyze the effects of allergic diseases on SD based on the evaluation of the Female Sexual Function Index (FSFI) and International Index of Erectile Function (IIEF). RESULTS: Twelve observational studies were included after the selection process. The results generally suggested lower FSFI or IIEF scores in patients with asthma, allergic rhinitis, allergic rhinoconjunctivitis, and urticaria compared to the healthy control groups. The underlying factors of this relationship could be inflammation, psychological factors, hormonal changes, sleep disorders, sexual behavior-related allergic reactions, social economic status, and the use of medications. CONCLUSION: SD and allergic disease are interrelated based on the extant literature. This scoping review provides insights into the clinical implications of both entities, while more research studies are warranted to further elucidate this complex relationship.

RESUMO

PURPOSE: Dysphonia is a common symptom due to the coronavirus disease of the 2019 (COVID-19) infection. Nonetheless, it is often underestimated for its impact on human's health. We conducted this first study to investigate the global prevalence of COVID-related dysphonia as well as related clinical factors during acute COVID-19 infection, and after a mid- to long-term follow-up following the recovery. METHODS: Five electronic databases including PubMed, Embase, ScienceDirect, the Cochrane Library, and Web of Science were systematically searched for relevant articles until Dec, 2022, and the reference of the enrolled studies were also reviewed. Dysphonia prevalence during and after COVID-19 infection, and voice-related clinical factors were analyzed; the random-effects model was adopted for meta-analysis. The one-study-removal method was used for sensitivity analysis. Publication bias was determined with funnel plots and Egger's tests. RESULTS: Twenty-one articles comprising 13,948 patients were identified. The weighted prevalence of COVID-related dysphonia during infection was 25.1 % (95 % CI: 14.9 to 39.0 %), and male was significantly associated with lower dysphonia prevalence (coefficients: -0.116, 95 % CI: -0.196 to -0.036; P = .004) during this period. Besides, after recovery, the weighted prevalence of COVID-related dysphonia declined to 17.1 % (95 % CI: 11.0 to 25.8 %). 20.1 % (95 % CI: 8.6 to 40.2 %) of the total patients experienced long-COVID dysphonia. CONCLUSIONS: A quarter of the COVID-19 patients, especially female, suffered from voice impairment during infection, and approximately 70 % of these dysphonic patients kept experiencing long-lasting voice sequelae, which should be noticed by global physicians.

RESUMO

The purpose of this study is to evaluate the physicochemical properties and in vitro osteogenic activity of radiopaque calcium silicate-gelatin cements. The radiopacity, setting time, working time, flow, diametral tensile strength, pH value, washout resistance and morphology of the cements with gelatin (0, 5 and 10% by weight) were measured, which compared to a popular endodontic material, ProRoot white-colored mineral trioxide aggregate (WMTA). The cell morphology, cell attachment and proliferation, alkaline phosphatase and osteocalcin levels on the cements were measured by culturing the specimens with dental pulp cells. The results indicated that the presence of gelatin significantly (P < 0.05) reduced radiopacity and diametral tensile strength and prolonged setting time. Nevertheless, the 5 wt% gelatin cement had a radiopacity (5.1 mm of Al thickness) higher than ISO 6876:2001 standards (3 mm of Al thickness). The setting time (33 min), working time (9 min) and flow value (17.4 mm) of the 5 wt% gelatin cement were significantly (P < 0.05) better than those of WMTA (corresponding 165, 6 min and 14.2 mm). The fresh WMTA completely degraded after soaking in a physiological solution for 1 h, while the gelatin cements resisted washout, showing no noticeable breakdown even after 1 day of soaking. The gelatin cement enhanced the higher expression of cell attachment, proliferation and differentiation as compared to WMTA. It was concluded that the 5 wt% gelatin-calcium silicate hybrid cement appears to be promising as a radiopaque biomaterial for medical applications such as endodontics and vertebroplasty.

RESUMO

OBJECTIVE: To investigate the incidence rate of postextubation dysphagia (PED) in patients with COVID-19, as well as relative factors potentially influencing the clinical course of dysphagia. DATA SOURCES: Six databases including PubMed, MEDLINE, Embase, ScienceDirect, the Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science were searched with no restriction on the language. REVIEW METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Data were extracted and cross-examined among 3 of the authors. The random-effects model was adopted for the statistical synthesis. The percentage and 95% confidence interval (CI) were adopted as the effect measurements of the PED incidence rate. Subgroup analyses, sensitivity analyses, and metaregression were also performed to identify the heterogeneity among the studies. RESULTS: A total of 594 patients were enrolled and analyzed from the 10 eligible studies. The weighted incidence of PED in patients with COVID-19 was 66.5% (95% CI: 49.7%-79.9%). Age was the potential factor influencing the incidence rate after heterogeneity was adjusted by the metaregression analysis. CONCLUSION: Compared to the current evidence reporting only 41% of the non-COVID patients experienced PED, our study further disclosed that a higher 66.5% of COVID-19 patients suffered from PED, which deserves global physicians' attention. With the association between COVID-19 and dysphagia having been more clearly understood, future clinicians are suggested to identify intubated patients' risk factors earlier to strengthen PED care programs in the era of COVID-19.

RESUMO

A novel one-step, closed-tube, loop-mediated isothermal amplification (LAMP) assay for detecting Entamoeba histolytica, one of the leading causes of morbidity in developing countries, was developed. The sensitivity of the LAMP assay is 1 parasite per reaction. A total of 130 clinical samples were analyzed, and the results compared with those of conventional nested PCR to validate the practicability of this assay. No DNA was amplified from other diarrheal pathogens, such as other Entamoeba species, bacteria, and viruses. These results indicate that LAMP is a rapid, simple, and valuable diagnostic tool for epidemiological studies of amebiasis.

RESUMO

Calcium phosphate cements (CPCs) have many favorable properties that support their clinical use as bone defect repair. However, it is difficult to deliver to the required site and hard to compact adequately due to inherently low ductility of ceramics. The aim of this study focused on the effect of the gelatin content on properties of CPCs. The diametral tensile strength, morphology, and weight loss of gelatin cements were evaluated after immersion in physiological solution, in addition to setting time. The results indicated that the setting time significantly increased with increasing gelatin amount. The 2 wt.% gelatin could make CPCs attain the maximum strength value of 2.1 MPa at 15-day immersion, while 1.6 MPa for the cement without gelatin. It is concluded that the presence of gelatin improved mechanical properties of CPCs; in particular, 2 wt.% gelatin. CPCs containing 2 wt.% gelatin hardened in an acceptable time recommended for clinical applications.

RESUMO

Timely diagnosis of drug-resistant tuberculosis (DR-TB) is beneficial for case treatment and management. We implemented an algorithm to improve molecular diagnostic utilization to intensify DR-TB case findings. The GeneXpert MTB/RIF (Xpert) test was used for initial diagnosis. Samples with Mycobacterium tuberculosis complex (MTBC)-positive and rifampicin resistance (RR) results were subsequently and simultaneously tested using the GenoType MTBDRplus (DRplus) and MTBDRsl (DRsl) tests. This prospective cohort study enrolled 2957 high-risk DR-TB cases. We tested sputum specimens using conventional mycobacteriological and molecular tests. Gene sequencing was performed to resolve discordant results. According to the Xpert test, 33.6% of specimens were MTBC-positive and 5.1% were RR. RR specimens were further analyzed in the DRplus and DRsl tests. We identified 1 extensively drug-resistant (XDR), 8 pre-XDR, 18 simple multidrug-resistant (MDR), 22 mono-RR, and 2 RR cases with concurrent second-line injection DR-TB. Of these, 25 (49%) were relapses, 13 (25.5%) were treatment failures, 10 (19.6%) were from MDR-TB high-incidence areas/countries, 1 was from MDR-TB contact and 2 were unknown. Among culture-positive TB cases, the sensitivities, specificities, and positive predictive values (PPVs) of the Xpert test and RR cases were 73.6% and 100.0%, 85.7% and 98.6%, and 73.5% and 80.0%, respectively. Gene sequencing of discordant results revealed 7 disputed rpoB mutations and 2 silent mutations for RIF, 1 ahpC mutation for isoniazid and 1 gyrA mutation for fluoroquinolone. The algorithm effectively identified approximately 23% of annual MDR-/XDR-TB and 37.5% of RR-TB cases that were enrolled in our DR-TB treatment and management program within 3 days.

RESUMO

BACKGROUND: To enhance calcium silicate cements (CSCs) towards a specific clinical application of endodontics and vertebroplasty, the addition of oxide dopants (Bi2O3, SrO, ZnO, ZrO2) as radiopacifiers allows for tailoring of material properties. OBJECTIVE: Effects of oxide dopants on the in vitro physicochemical properties and osetogenic activity of CSCs were investigated. METHODS: The setting time, compressive strength, radiopacity, and osteogenic ability of the cements were evaluated. The ability of cement samples to support MG63 attachment, proliferation, differentiation, and mineralization was assessed. RESULTS: The greater the oxide amount, the higher the setting time and radiopacity were in the cement. The effect of the oxide dopants on radiopacity followed the order Bi2O3 > ZrO2 > SrO > ZnO, which were greater than 3 mm of Al recommended by ISO 6876: 2001 standards. ZrO2 could reinforce compressive strength of the control cement, while ZnO remarkably reduced the strength. The adverse effect of Bi2O3 and ZrO2 was found on cell number, alkaline phosphatase (ALP) activity and mineralization of MG63 cells. SrO supported cell attachment, proliferation and differentiation, and significantly increased cellular mineralization compared to the control. CONCLUSIONS: The 20 wt% SrO-containing CSCs may be applied to endodontic treatment and vertebroplasty surgery.

RESUMO

BACKGROUND/PURPOSE: This study assessed how positive expiratory pressure (PEP) affected pulmonary function, functional capacity, and subjective cough difficulty in individuals with chronic obstructive pulmonary diseases (COPD). METHODS: This was a prospective, randomized, controlled study. Subjects were recruited from an outpatient department at a university hospital. Thirty-two patients with COPD were allocated to either PEP + FET (forced expiratory technique) group (n = 16) or FET only group (n = 16). Subjects in PEP + FET and FET groups were in a clinically stable condition before and during the study. Subjects in the PEP + FET group received PEP breathing using a mouth adjunct to FET, and the FET group was administered FET for 4 weeks only. Patients received weekly follow-up during the study period. Pulmonary function, 6-minute walk tests, and subjective cough difficulty scores were measured before and after the 4-week interventions. RESULTS: Subjects in the PEP + FET group had a significantly increased diffusing capacity (DLCO) compared to preintervention (p < 0.05) and after intervention in the FET group (p < 0.05). DLCO significantly increased in the PEP + FET group from 18.0 +/- 7.3 to 20.1 +/- 7.2 mL/min/mmHg. The 6-minute walking distance (6MWD) also increased significantly from 516.8 +/- 94.1 to 570.6 +/- 60.4 m in the PEP + FET group (p < 0.001) after intervention, compared to that for the FET group (p < 0.05). Additionally, the PEP + FET group had significantly lower cough difficulty scores compared to those at baseline and in the FET group. CONCLUSION: Four-week PEP therapy as an adjunct to FET further enhanced DLCO and 6MWD, and reduced cough difficulty compared to FET only in COPD patients with mucus hypersecretion.

RESUMO

Although human toxoplasmosis is a notifiable disease in Taiwan since 2007, little is known about its risk factors. This study aimed to investigate the risk factors for acute Toxoplasma gondii diseases in Taiwan. We conducted a nationwide population-based case-control study. Cases of acute human toxoplasmosis notified to the Taiwan Centers for Diseases Control (Taipei, Taiwan) during 2008-2013 were compared with controls that were randomly selected from healthy T. gondii-seronegative blood donors who participated in a nationwide T. gondii seroepidemiologic study during 2009-2010. Cases and controls were matched according to age, gender and residency at an 1:8 ratio. Structured questionnaires were used to gather information regarding risk factors. A total of 30 laboratory-confirmed acute T. gondii disease cases and 224 controls were enrolled. The most common clinical manifestation of the cases was flu-like symptoms (n = 20), followed by central nervous system disease (n = 4), ocular diseases (n = 3), abortion (n = 2), and congenital infection (n = 1). Multivariate conditional logistic regression showed that raw clam consumption (adjusted odds ratio [OR] = 3.7; 95% confidence interval [CI] = 1.4-9.9) and having a cat in the household (adjusted OR = 2.9; 95% CI = 1.1-7.9) were two independent risk factors for acute T. gondii disease. We conclude that raw shellfish consumption and domestic cat exposure were risk factors for acquiring acute T. gondii diseases in Taiwan. This finding may guide future research and control policies.

RESUMO

Toxoplasma gondii is an opportunistic, zoonotic pathogen with a worldwide distribution. There are large variations in the seroprevalence of T. gondii infection in different regions of the world. Although toxoplasmosis became a notifiable communicable disease in Taiwan in 2007, little is known about its epidemiology among the general population. This cross-sectional study aimed to survey the seroprevalence of T. gondii infection and its risk factors among healthy blood donors in Taiwan. Through collaborating with the Taiwan Blood Services Foundation, a total of 1,783 healthy blood donors from all six-branch blood service centers participated in this study. The blood samples were tested for the presence of T. gondii antibodies and DNA using enzyme immunoassays and real-time PCR, respectively. Structured questionnaires were used to gather information on risk factors for T. gondii infection. Of the 1,783 participants, 166 (9.3%) tested positive for anti-Toxoplasma IgG, while 5 (0.28%) tested positive for anti-Toxoplasma IgM. The five IgM positive donors had high avidity antibodies suggestive of past infection. No active parasitemia was detected by real-time PCR assays. Multivariate logistic regression showed that undercooked pork meat consumption (adjusted odds ratio [OR] = 2.9; 95% confidence interval [CI]: 1.3-6.5), raw mussels consumption (adjusted OR = 5.3; 95% CI: 1.5-19.1), having a cat in the household (adjusted OR = 2.0; 95% CI: 1.2-3.2), a lower education level (adjusted OR = 1.6; 95% CI: 1.1-2.3), and donation place in eastern Taiwan (adjusted OR = 2.5; 95% CI: 1.6-3.9) were independent risk factors for Toxoplasma seropositivity. These findings provide information on the seroprevalence and epidemiology of T. gondii infection among healthy blood donors in Taiwan.

RESUMO

INTRODUCTION: The purpose of this study was to comparatively examine physicochemical and biocompatible properties of 20 wt% bismuth oxide (Bi(2)O(3))-containing dicalcium silicate cement and white-colored mineral trioxide aggregate (WMTA). METHODS: The radiopacity, setting time, diametral tensile strength, pH value, morphology, and phase composition of the cements with and without Bi(2)O(3) were measured after mixing powders with water. Cement biocompatibility was evaluated by incubating the cement specimens with MG63 human osteoblast-like cells. RESULTS: The addition of Bi(2)O(3) to the cement led to a significant increase (p < .05) in the setting time of 24 minutes. It was accompanied by a small decrease in the pH value but without adversely affecting diametral tensile strength. The radiopacity value of the Bi(2)O(3)-containing cement was equivalent to 7.3 mm of aluminum, which was significantly higher (p < 0.05) than pure cement without Bi(2)O(3) (1.1 mm of aluminum) but lower (p < .05) than WMTA (9.3 mm of aluminum). However, it was greater than 3 mm of aluminum, which is the value recommended by ISO 6876/2001 standards. MG63 cell viability cultured on Bi(2)O(3)-containing cement was higher than that cultured on WMTA at all culture times. CONCLUSIONS: The dicalcium silicate cement with 20 wt% Bi(2)O(3) showed shortened setting time and good biocompatibility and thus may have the potential to be a root-end filling material alternative to MTA.
