There are many barriers for condom use, which was one of the most important methods to prevent the transmission of HIV among female sex workers. Therefore, the aim of the present study was to identify the barriers to condom use among female sex workers in Tehran, Iran.

This study was conducted with a qualitative approach and conventional content analysis among female sex workers in Tehran. Twenty-two female sex workers were selected through snowball sampling and purposive sampling. The data gathering method was a semi-structured interview and the data were analyzed using Graneheim and Lundman method. Guba and Lincoln criteria were used for evaluating research transferability.

The results of data analysis were categorized in three categories and seven sub-categories included 1) individual factors (not knowing HIV/AIDS properly, anti-loyalty and love, and personality traits), 2) structural factors (partner's desire, problems with condom availability), and 3) cultural factors (cultural taboos, following the models).

The results showed that lack of condom use is the consequence of different individual, structural, and cultural factors. So, it can be useful to take some initiatives at the individual level by raising awareness and understanding of female sex workers about HIV at the structural level by lowering the price of condoms and providing them extensively and at the societal level, by changing the beliefs and taboos about condoms.

For hospitalised cases of COVID-19, a number of events during hospitalization are of interest regarding the influence of risk factors on the likelihood of experiencing these events. The same is true for predicting times from hospital admission of COVID-19 patients to intensive care or from start of ventilation (invasive or non-invasive) to extubation. This logical restriction of the data to the period of hospitalisation is associated with a substantial risk that inappropriate methods are used for analysis. Here, we briefly discuss the most common types of bias which can occur when analysing in-hospital COVID-19 data.
Sentinel lymph node biopsy (SLNB) was introduced over 30 years ago, but the application of SLNB in China is unclear. This study aimed to explore the real-world implementation of SLNB among early-stage breast cancer patients in China.

A multi-center, retrospective study was conducted among primary breast cancer patients from 37 hospitals in China in 2018. Their clinical data were collected and analyzed, including the implementation status of SLNB in China, subsequent processing of sentinel lymph nodes (SLNs) containing metastases, and the effect of neoadjuvant chemotherapy (NAC) on SLNB.

SLNB surgery was performed on 43.5% of early-stage breast cancer patients in China and 11,942 patients who underwent SLNB were enrolled in this study. The majority of SLNBs were performed using a single mapping agent. A combination of blue dye and radiotracer or fluorescence imaging was used in only 14.9% of patients. The mean (SD) number of resected SLNs was 4.0 (2.1). For the patients with 1 or 2 positive SLNs, 83.0% oitive patients.[This corrects the article DOI 10.2147/CMAR.S254296.].
Malignancy prediction models for pulmonary nodules are most accurate when used within nodules similar to those in which they were developed. This study was to establish models that respectively predict malignancy risk of incidental solid and subsolid pulmonary nodules of different size.

This retrospective study enrolled patients with 5-30 mm pulmonary nodules who had a histopathologic diagnosis of benign or malignant. The median time to lung cancer diagnosis was 25 days. Four training/validation datasets were assembled based on nodule texture and size subsolid nodules (SSNs) ≤15 mm, SSNs between 15 and 30 mm, solid nodules ≤15 mm and those between 15 and 30 mm. Univariate logistic regression was used to identify potential predictors, and multivariate analysis was used to build four models.

The study identified 1008 benign and 1813 malignant nodules from a single hospital, and by random selection 1008 malignant nodules were enrolled for further analysis. There was a much higher malignancy rate among SSNs clinicians.
Nasopharyngeal carcinoma (NPC) is more common among women in Southeast Asia. An important issue is whether it is safe for them to bear children after treatment and when it is safe to do so. We conducted this study to explore the relation between fertility and prognosis in child-bearing women with NPC.

Child-bearing women were defined as young women between the ages of 18 and 30. A total of 127 eligible child-bearing NPC patients were identified from December 2003 to December 2014. The patients were divided into two groups, depending on whether or not they had post-therapeutic births. The Kaplan-Meier method was used for survival analyses. The Log rank test was used to compare two survival curves and the independent significances of different prognostic factors were assessed by Cox proportional hazards regression analysis.

The 5-year overall survival (OS) and disease-free survival (DFS) in the Childbirth group were significantly higher than those in the Non-Childbirth group (100% vs 88.8%, P = 0.026 and 100% vs 77.5%, P = 0.007, respectively). In the Childbirth group, no difference was found in the 5-year DFS between different birth interval times, from 1 to 5 years after treatment. The clinical stage was identified as the risk factor of OS (HR = 101.725, 95% CI 2.160-4790.910, P = 0.019), and consequent childbirth after treatment was associated with favorable DFS (HR = 0.148, 95% CI 0.034-0.643, P = 0.011).

Post-therapeutic birth did not increase the mortality risk of child-bearing women with NPC. There was no significant correlation between the subsequent birth time window after treatment and the prognosis.

Non-curative resection (NCR) remains problematic in some cases of early gastric carcinomas (EGCs) treated by endoscopic submucosal dissection (ESD). The aim of this study was to identify predictors of NCR, especially of eCura C1 and eCura C2 resections, before ESD and study long-term outcomes of EGC patients with NCR.

A retrospective review of medical records was conducted over an 8-year period for EGCs undergoing ESD. Clinicopathologic and endoscopic characteristics and patients' survival were analyzed. Risk factors for NCR and eCura C1 and C2 resections were assessed by logistic analyses. Survival of patients was estimated with the Kaplan-Meier method with a Log rank test.

A total of 463 patients with 472 lesions were qualified. By univariate and multivariate analyses, the predictors for NCR and eCura C2 resections were tumor size >20 mm, tumors located in cardia-fundus, uneven surface, margin elevation, and mixed and undifferentiated types, and those for eCura C1 resection were tumors located in cardia-fundus, negative lifting sign, and mixed and undifferentiated types. The 5-year cancer-specific and cancer-free survival rates were 100.0% and 94.2%, and 95.3% and 83.4% in the curative resection (CR) and NCR groups, respectively. The 5-year cancer-specific and cancer-free survival rates were significantly greater in the CR group than that in the NCR group (
<0.0001).

In this cohort, we identified various endoscopic and pathologic features of EGCs to predict NCR, especially eCura C1 and eCura C2 resections before ESD. These clinically valuable factors would be very informative to endoscopists and surgeons who perform ESD to resect EGCs.

Monoamine oxidase A (MAO-A) is a mitochondrial protein involved in tumourigenesis in different types of cancer. However, the biological function of MAO-A in gastric cancer development remains unknown.

We examined MAO-A expression in gastric cancer tissues and in gastric cancer cell lines by immunohistochemistry and Western blot analyses. CCK8, FACS and bromodeoxyuridine incorporation assays were performed to assess the effects of MAO-A on gastric cancer cell proliferation. The role of MAO-A in mitochondrial function was determined through MitoSOX Red staining, ATP generation and glycolysis assays.

In the present study, we observed that MAO-A was significantly upregulated in gastric cancer tissues and in AGS and MGC803 cells. The observed MAO-A inhibition indicated decreased cell cycle progression and proliferation. Silencing MAO-A expression was associated with suppressed migration and invasion of gastric cancer cells in vitro. Moreover, alleviated mitochondrial damage in these cells was demonstrated by decreased levels of mitochondrial reactive oxygen species and increased ATP generation. MAO-A knockdown also regulated the expression of the glycolysis rate-limiting enzymes hexokinase 2 and pyruvate dehydrogenase. Finally, we observed that the glycolysis-mediated effect was weakened in AGS and MGC803 cells when MAO-A was blocked.

The findings of the present study indicate that MAO-A is responsible for mitochondrial dysfunction and aerobic glycolysis, which in turn leads to the proliferation and metastasis of human gastric tumour cells.

Chemotherapeutic drugs often cause obvious toxicity and side effects. Moxibustion can improve the immunity of cancer patients, enhance cellular immunity, and reduce the toxicity and adverse effects of radiotherapy and chemotherapy. In this study, the efficacy of moxibustion combined with paclitaxel on breast cancer was evaluated.

A breast cancer mouse model was established. Hematoxylin and eosin staining was used to analyze tumor necrosis in mouse tumors. selleck inhibitor Immunohistochemistry, Western blot, and qPCR were used to detect the expression of CD34, hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor A(VEGFA), programmed death-1 (PD-1), and programmed death-1 ligand (PD-L1) in tumor tissues.

Moxibustion combined with paclitaxel significantly inhibited weight loss in breast cancer-burdened mice and increased the survival rate. Moxibustion combined with paclitaxel increased the number of white blood cells, thymus index, and spleen index, and enhanced immune function by upregulating interferon-gamma and interleukin-2 and downregulating interleukin-10 and transforming growth factor-β1.
