“Our feelings are valid” – reviewing the lesbian, gay, and bisexual affirmative approaches in a mental health setting

Abstract In recent years, although research into support mechanisms for managing distress experienced by Lesbian Gay and Bisexual (LGB) communities has increased. Stigma-related discrimination related to sexual minority status remains. This is further compounded by stigma against mental illnesses thus creating double jeopardy. This review will outline recent discoveries by exploring existing theories highlighting factors that explain health disparities for cisgender LGB people. It appears that the experience of the LGB population and the use of psychological therapies is varied across the spectrum. Some focus upon symptom reduction as part of the experience, but others talk about not being validated. Some mention minority stress constructs, alongside the psychological mediation framework, which offers a potential theoretical understanding of the experiences of the LGB population who receive psychological therapies.
Do Pornography Use and Masturbation Frequency Play a Role in Delayed/Inhibited Ejaculation during Partnered Sex? A Comprehensive and Detailed Analysis

The role of masturbation frequency and pornography use on sexual response during partnered sex has been controversial, the result of mixed and inconsistent findings. However, studies investigating this relationship have often suffered from methodological shortcomings. We investigated the role of masturbation frequency and pornography use on both the occurrence and severity of delayed/inhibited ejaculation (DE), an increasingly common sexual problem among men. We did so in a large (nonclinical) multinational sample of cisgender men (N = 2332; mean age = 40.3, SE = 0.31) within a multivariate context that relied on multiple (and, when possible, standardized) assessments of sexual dysfunctions while controlling for possible confounding variables. Results indicated a weak, inconsistent, and sometimes absent association between the frequency of pornography use and DE symptomology and/or severity. In contrast, both poorer erectile functioning and anxiety/depression represented consistent and strong predictors of DE and, to a lesser extent, DE severity. Other factors, including relationship satisfaction, sexual interest, and masturbation frequency, were significantly though moderately to weakly associated with DE. In conclusion, associations (or sometimes lack thereof) between masturbation frequency, pornography use, and delayed ejaculation are more clearly understood when analyzed in a multivariate context that controls for possible confounding effects.
Hospitalizations and in-hospital outcomes in patients with ST-elevation myocardial infarction during the coronavirus disease 2019 pandemic: The Albanian experience

Objective Global studies report a significant decline in ST-elevation myocardial infarction (STEMI) related hospitalization rates during the coronavirus disease 2019 (COVID-19) pandemic outbreak. However, there have been several divergent reports on hospital outcomes. In this study, we aim to investigate the impact of the COVID 19 outbreak on hospitalizations because of STEMI and in-hospital outcomes in Albania. Methods This was a retrograde study, collecting data for hospitalizations because of STEMI from March 9, (first COVID 19 case in our country) to April 30, 2020, (period of total lockdown) compared with the same period in 2019 at our center. The incidence rate ratio (IRR) was used to compare admissions because of STEMI and procedures and the risk ratio (RR) to compare mortality and other complication rates. Results Admissions for STEMI declined during the COVID-19 period from a total of 217 in 2019 to 156 in 2020 (−28.1%) representing IRR 0.719 (p=0.033). PCIs also reduced from 168 procedures in 2019 to 113 in 2020 (−33%), representing an IRR of 0.67, p=0.021. The time from symptom onset to arrival at our intensive care unit was significantly higher in 2020 compared to 2019 (925.6±1097 vs. 438.7±385 minutes, p<0.001). The STEMI death rate during the pandemic compared to the control period was significantly increased to 14.1% vs. 7.8% (RR=1.91 p=0.037, but with no significant increase in primary PCI-STEMI death rate (8.9% vs. 4.8% RR=1.85 p=0.217). Cardiogenic shock also increased during the pandemic to 21.2% from 12.4% in 2019 (RR=1.70 p=0.025). Conclusion Hospitalizations and revascularization procedures for STEMI significantly reduced during the COVID-19 pandemic. We identified a substantial increase in the STEMI mortality rate and cardiogenic shock during the pandemic outbreak. Delayed timely reperfusion intervention might be responsible for the increased risk for complications.
A survey of the opportunities and challenges of supervised machine learning in maritime risk analysis

ABSTRACT Identifying and assessing the likelihood and consequences of maritime accidents has been a key focus of research within the maritime industry. However, conventional methods utilised for maritime risk assessment have been dominated by a few methodologies each of which have recognised weaknesses. Given the growing attention that supervised machine learning and big data applications for safety assessments have been receiving in other disciplines, a comprehensive review of the academic literature on this topic in the maritime domain has been conducted. The review encapsulates the prediction of accident occurrence, accident severity, ship detentions and ship collision risk. In particular, the purpose, methods, datasets and features of such studies are compared to better understand how such an approach can be applied in practice and its relative merits. Several key challenges within these themes are also identified, such as the availability and representativeness of the datasets and methodological challenges associated with transparency, model development and results evaluation. Whilst focused within the maritime domain, many of these findings are equally relevant to other transportation topics. This work, therefore, highlights both novel applications for applying these techniques to maritime safety and key challenges that warrant further research in order to strengthen this methodological approach.
The Role of TLR2 in Infectious Diseases Caused by Mycobacteria: From Cell Biology to Therapeutic Target

Simple Summary Due to the broad functions of Toll-like receptor 2 (TLR2) in innate immunity, the drive for the development of TLR2-targeted therapeutic treatments has accelerated in recent decades. However, its dual role in both the activation and suppression of innate immune responses makes it very difficult to use the results from gathered basic research and apply them to the development of clinical trials. Therefore, this review aims to summarize the knowledge of the function of TLR2 in innate immunity and metabolism to provide some future research directions. Abstract Innate immunity is considered the first line of defense against microbial invasion, and its dysregulation can increase the susceptibility of hosts to infections by invading pathogens. Host cells rely on pattern recognition receptors (PRRs) to recognize invading pathogens and initiate protective innate immune responses. Toll-like receptor 2 (TLR2) is believed to be among the most important Toll-like receptors for defense against mycobacterial infection. TLR2 has been reported to have very broad functions in infectious diseases and also in other diseases, such as chronic and acute inflammatory diseases, cancers, and even metabolic disorders. However, TLR2 has an unclear dual role in both the activation and suppression of innate immune responses. Moreover, in some studies, the function of TLR2 was shown to be controversial, and therefore its role in several diseases is still inconclusive. Therefore, although TLR2 has been shown to have an important function in innate immunity, its usefulness as a therapeutic target in clinical application is still uncertain. In this literature review, we summarize the knowledge of the functions of TLR2 in host–mycobacterial interactions, discuss controversial results, and suggest possibilities for future research.
Upconversion Luminescent Humidity Sensors Based on Lanthanide-Doped MOFs

Lanthanide-doped metal-organic frameworks (Y/Yb/Er-MOF) were synthesized by a low-cost solvothermal method. The obtained Y/Yb/Er-MOF shows the cooperative upconversion luminescence of Yb3+ and upconversion luminescence of Er3+ (Yb3+-sensitized) irradiated by a continuous wave 980 nm laser. In order to explore the potential application of Y/Yb/Er-MOF in relative humidity (RH) sensors, the RH responsiveness of Y/Yb/Er-MOF was investigated by measuring the intensity changes of upconversion luminescence. The Y/Yb/Er-MOF possesses two luminescence centers, in which Yb3+ forms emission at 500 nm through the cooperative luminescence effect, and Er3+ achieves 660 nm emission through excited state absorption and successive energy transfer from Yb3+. Hence, the ratio meter luminescence sensor for RH is constructed based on Y/Yb/Er-MOF. The results show that the response of Y/Yb/Er-MOF to RH presents a linear relationship in the range of 11–95%. The cycle stability of Y/Yb/Er-MOF responses to RH was investigated with the intensity changes of upconversion luminescence, and the recovery ratio was more than 93% each time. Therefore, the Y/Yb/Er-MOF is a humidity-sensitive material with great potential for applications such as humidity sensors.
Generating pre-harvest crop maps by applying convolutional neural network on multi-temporal Sentinel-1 data

ABSTRACT Pre-harvest crop mapping, the fundamental requirement for many of the crop management decisions, continues to be challenging either due to cloud cover in satellite images or due to spectral separability issues. These limitations are overcome in this study by using Synthetic Aperture Radar (SAR) data and deep learning technique. Two-dimensional convolutional neural network (2D-CNN) architecture is applied on multi-temporal SAR data of Sentinel-1 to classify soybean, jowar, cotton and sugarcane crops in a large geographic area located in a Central Indian state. Classification experiments are conducted with full season data from nine overpasses in three modes namely VH alone, VH and VH/VV ratio, and VH and VV, and these experimental results reveal that VH and VV combination performed better with an overall accuracy of 91.75% as compared to 84.96% and 88.75% respectively by others. Classification performances with three sets of temporal data, covering part of the season, reveal that crop map can be generated as early as 27th August (i.e. roughly 45 days prior harvesting) with an accuracy of 89.15% slightly less than the mapping accuracy achieved with full season data (i.e. till 14th October). 2D-CNN algorithm has performed better than SVM and RF techniques. This methodology can be extended to similar agro-ecological regions of the country. Richly available SAR data from Sentinel-1 and the potential of deep learning techniques for recognising complex phenological patterns offer immense opportunities for early-season crop mapping even during monsoon season in tropical countries like India.
Intra-African Trade and Spatial Dependence: Revisiting Africa Intra-Trade Determinants with a Spatial Structural Gravity Model

The objective of our paper is to revisit African intra-trade determinants once taking into account potential spatial spillover effect due to the third country dependence. Recently, several studies have shown the importance of taking into account the spatial effect. We examined total exports flows, industrial trade flows and agricultural trade flows of 40 countries in 2002-2018 and we detected a positive spatial autocorrelation and the Spatial Autoregressive gravity model is identified as an appropriate way to model the spatial dependence. The results show that distance doesn’t affect agricultural products trade, institutional factors of destination country and neighboring countries affect intra-African trade. Except SADC area, intra-African trade is largely dominated by agricultural products. To reduce poverty through trade intensification, the regional integration process in Africa must grant an important place to industrialization policies, conflict resolution and strengthening cooperation.
Reinforcing Poly(methyl methacrylate) with Bacterial Cellulose Nanofibers Chemically Modified with Methacryolyl Groups

Nanofibrillated bacterial cellulose (NFBC), a type of cellulose nanofiber biosynthesized by Gluconacetobacter sp. , has extremely long (i.e., high-aspect-ratio) fibers that are expected to be useful as nanofillers for fiber-reinforced composite resins. In this study, we investigated a composite of NFBC and poly(methyl methacrylate) (PMMA), a highly transparent resin, with the aim of improving the mechanical properties of the latter. The abundant hydroxyl groups on the NFBC surface were silylated using 3-(methacryloyloxy)propyltrimethoxysilane (MPTMS), a silane coupling agent bearing a methacryloyl group as the organic functional group. The surface-modified NFBC was homogeneously dispersed in chloroform, mixed with neat PMMA, and converted into PMMA composites using a simple solvent-casting method. The tensile strength and Young’s modulus of the composite increased by factors of 1.6 and 1.8, respectively, when only 0.10 wt% of the surface-modified NFBC was added, without sacrificing the maximum elongation rate. In addition, the composite maintained the high transparency of PMMA, highlighting that the addition of MPTMS-modified NFBC easily reinforce PMMA. Furthermore, interactions involving the organic functional groups of MPTMS were found to be very important for reinforcing PMMA.

The impact of psycho-education on school-children’s homophobic attitudes

Abstract Homophobic bullying is a major social issue, especially in the school settings. This may be particularly common in many Western countries but it appears globally. Bullying causes both short and long-term problems hence its prevention must be seen as a relevant and urgent step in educational settings. Psycho-educational programs should be promoted in order to help eliminate school-children’s prejudices and bias about gay and lesbian peers, homophobic bullying. 191 school-children (n = 101 females, n = 90 males), aged 12–14 years old, attending a secondary school in Foggia (Italy) were recruited and assessed at baseline (T0) and 2 months (T1) after receiving a systematized, repeated psycho-education aimed to promote their awareness on sexual variations, and reduce homophobic prejudices and stereotypes. They were assessed for their empathy quotients, their knowledge of gender– related stereotypes, homophobic attitudes, anger, emotional regulation, before (T0) and after the intervention (T1) in a standardized manner. The psychoeducational program significantly reduced homophobia levels towards gays (−9.38%) and lesbians (−5.42%,) as well as improved emotional adjustment (+25.9%) and pro-sociality (+3.85%) among school-children (0.0486≤ all p < 0.0001). Also, a statistically significant improvement of empathy (+11.3%) and levels of state anger (+0.35%) has been significantly reported. This study reports on the benefits of a repeated, systematic, prospective psycho-educational intervention conducted in the school-setting leading to an improvement of empathy, pro-sociality, emotional regulation and a reduction of homophobic attitudes and anger among students.
Serum Oncomarkers In Patients With MPO-ANCA-Positive AAV: Diagnostic And Prognostic Predictive Values For Interstitial Lung Disease

Purpose: To explore in myeloperoxidase anti-neutrophil cytoplasmic antibody-positive anti-neutrophil cytoplasmic antibody-associated vasculitis (MPO-AAV) the value of circulating oncomarkers in identifying interstitial lung disease (ILD) and predicting prognosis. Methods: Newly diagnosed MPO-AAV patients were recruited retrospectively at a single center. The serum levels of carbohydrate antigen (CA) 19-9, CA125, cytokeratin fraction 21-1 (CYFRA21-1), carcinoembryonic antigen, squamous cell carcinoma antigen and neuron-specific enolase were compared between patients with and without ILD. The strength of the oncomarkers in identifying ILD was assessed through logistic regression and receiver operating characteristic (ROC) curves. Correlation analysis was applied to detect the associations between oncomarkers and ILD severity. The significance of serum oncomarkers as prognosis predictors for MPO-AAV associated ILD was evaluated by survival analysis. Results: 169 MPO-AAV patients were included and ILD was found in 101 patients. Serum CA125, CA19-9 and CYFRA21-1 were significantly higher in patients with ILD than those without ILD. The area under the ROC curve of CA19-9, CA125, and CYFRA21-1 for identifying ILD was 0.701, 0.660, and 0.711, respectively. A specificity of 98.5% for diagnosing ILD was found for CA19-9 at the recommended normal level. CA19-9 was positively correlated with HRCT fibrosis score (r = 0.498, p < 0.001) and CYFRA21-1 was correlated with ground-glass score (r = 0.316, p = 0.002). Both CA19-9 and CYFRA21-1 were independent risk factors for all-cause mortality in patients with ILD. Conclusion: Serum CA19-9 and CYFRA21-1 maybe useful markers in the diagnosis, disease severity evaluation and prognosis prediction of MPO-AAV associated ILD.
Persistence of Antibiotic-Resistant Escherichia coli Strains Belonging to the B2 Phylogroup in Municipal Wastewater under Aerobic Conditions

Escherichia coli is classified into four major phylogenetic groups (A, B1, B2, and D) that are associated with antibiotic resistance genes. Although antibiotic-resistant E. coli is commonly detected in municipal wastewater, little is known about the relationship between the phylogenetic groups and antibiotic-resistant E. coli in wastewater. In this study, the survival of E. coli in wastewater and the changes to the relationships between each phylogroup and the antibiotic-resistant profiles of E. coli isolates from wastewater were investigated under aerobic conditions for 14 days. The isolates were classified into the phylogroups A, B1, B2, and D or others by multiplex PCR. In addition, the susceptibility of the isolates to 11 antibiotics was assessed with the minimum inhibitory concentration (MIC) assay. While E. coli counts decreased in the wastewater with time under aerobic conditions, the prevalence of phylogroup B2 had increased to 73% on day 14. Furthermore, the MIC assay revealed that the abundance of antibiotic-resistant E. coli also increased on day 14. After batch-mixing the experiments under aerobic conditions, the surviving antibiotic-resistant E. coli included mainly multidrug-resistant and beta-lactamase-producing isolates belonging to phylogroup B2. These results suggest that the phylogroup B2 isolates that have acquired antibiotic resistance had a high survivability in the treated wastewater.
Isolation, Identification and Pharmacological Effects of Mandragora autumnalis Fruit Flavonoids Fraction

Since ancient times, Mandragora autumnalis has been used as a traditional medicinal plant for the treatment of numerous ailments. In light of this, the current study was designed to isolate and identify the chemical constituents of the flavonoids fraction from M. autumnalis ripe fruit (FFM), and evaluate its DPPH scavenging, anti-lipase, cytotoxicity, antimicrobial and antidiabetic effects. An ethyl acetate extract of M. autumnalis was subjected to a sequence of silica gel column chromatography using different eluents with various polarities. The chemical structures of the isolated compounds were identified using different spectral techniques, including 1H NMR and 13C NMR. FFM’s anti-diabetic activity was assessed using a glucose transporter-4 (GLUT4) translocation assay, as well as an inhibition against α-amylase and α-glucosidase using standard biochemical assays. The FFM anti-lipase effect against porcine pancreatic lipase was also evaluated. Moreover, FFM free radical scavenging activity using the DPPH test and antimicrobial properties against eight microbial strains using the micro-dilution method were also assessed. Four flavonoid aglycones were separated from FFM and their chemical structures were identified. The structures of the isolated compounds were established as kaempferol 1, luteolin 2, myricetin 3 and (+)-taxifolin 4, based on NMR spectroscopic analyses. The cytotoxicity test results showed high cell viability (at least 90%) for up to 1 mg/mL concentration of FFM, which is considered to be safe. A dose-dependent increase in GLUT4 translocation was significantly shown (p < 0.05) when the muscle cells were treated with FFM up to 0.5 mg/mL. Moreover, FFM revealed potent α-amylase, α-glucosidase, DPPH scavenging and porcine pancreatic lipase inhibitory activities compared with the positive controls, with IC50 values of 72.44 ± 0.89, 39.81 ± 0.74, 5.37 ± 0.41 and 39.81 ± 1.23 µg/mL, respectively. In addition, FFM inhibited the growth of all of the tested bacterial and fungal strains and showed the greatest antibacterial activity against the K. pneumoniae strain with a MIC value of 0.135 µg/mL. The four flavonoid molecules that constitute the FFM have been shown to have medicinal promise. Further in vivo testing and formulation design are needed to corroborate these findings, which are integral to the pharmaceutical and food supplement industries.
BoLA-DRB3 Polymorphism Controls Proviral Load and Infectivity of Bovine Leukemia Virus (BLV) in Milk

Bovine leukemia virus (BLV), which causes enzootic bovine leukosis, is transmitted to calves through the milk of BLV-infected dams. Bovine leukocyte antigen (BoLA)-DRB3 is a polymorphic gene associated with BLV infectivity and proviral load (PVL). However, the effect of BoLA-DRB3 polymorphism on the infectivity and PVL of milk from BLV-infected dams remains unknown. This study examined milk from 259 BLV-infected dams, including susceptible dams carrying at least one BoLA-DRB3*012:01 or *015:01 allele with high PVL, resistant dams carrying at least one BoLA-DRB3*002:01, *009:02, or *014:01:01 allele with low PVL, and neutral dams carrying other alleles. The detection rate of BLV provirus and PVL were significantly higher in milk from susceptible dams than in that from resistant dams. This result was confirmed in a three-year follow-up study in which milk from susceptible dams showed a higher BLV provirus detection rate over a longer period than that from resistant dams. The visualization of infectivity of milk cells using a luminescence syncytium induction assay showed that the infectious risk of milk from BLV-infected dams was markedly high for susceptible dams compared to resistant ones. This is the first report confirming that BoLA-DRB3 polymorphism affects the PVL and infectivity of milk from BLV-infected dams.
