Neoadjuvant Chemotherapy in Patients with HER2-Negative Breast Cancer: A Report from Clinical Breast Cancer Registry of Iran.

BACKGROUND: Neoadjuvant chemotherapy (NCT) has become an increasingly popular approach in management of breast cancer (BC). This study was conducted to evaluate the pathologic response and 36-month recurrence and survival rates of patients with human epidermal growth factor receptor 2 (HER2)-negative BC treated with different NCT regimens. METHODS: A total of 163 female patients with HER2-negative BC who received NCT during 2017-2020 were identified from the Clinical Breast Cancer Registry of Iran and entered the study. The prescribed NCT regimens included 4 cycles of doxorubicin plus cyclophosphamide, 4 cycles of doxorubicin plus cyclophosphamide followed by 4 cycles of paclitaxel, 4 cycles of doxorubicin plus cyclophosphamide followed by 4 cycles of docetaxel or 6 cycles of doxorubicin plus cyclophosphamide plus docetaxel (TAC). RESULTS: Thirty-two patients (19.6%) experienced pathologic complete response (pCR). TAC regimen, triple negative-BC and ki67>10% were significantly associated with increased pCR. The recurrence, overall survival (OS) and disease-free survival (DFS) rate at 36 months for all patients were 16.6%, 84.7% and 79.8%, respectively. Type of neoadjuvant regimen as well as age, hormone receptor status, Ki67, grade, clinical stage, type of surgery and pathologic response to chemotherapy did not significantly influence the survival and recurrence; however, TAC results in improved recurrence, OS and DFS rates. CONCLUSION: This study provides further evidence that NCT is a viable treatment option for patients with HER2-negative BC. The TAC regimen resulted in a significantly higher pCR rate compared to other regimens, but did not result in a significant improvement in recurrence, OS and DFS and rates.

Barriers and Facilitators to Accessing Sexual and Reproductive Health Services Among Transgender People: A Meta-Synthesis.

The availability and accessibility of sexual and reproductive health (SRH) services for transgender individuals are crucial. This population is deprived of health care due to rejection, stigma, gender-based discrimination, confidentiality, and violence. This review attempts to provide readers with an account of the fundamental problems that the transgender population faces regarding experiences of SRH. This meta-synthesis review applied the Social-Ecological Model (SEM) to address trans individuals' SRH factors. The databases were searched using "SRH" and "transgender" keywords. Fifty studies were finally selected. All studies were qualitative, including 36 semi-structured/ in-depth interviews, two focus group studies, and 12 interviews and focus group studies. The Social-Ecological Model application illustrates the impact of individual, interpersonal, institutional, and social factors on the condition of SRH among transgender individuals. This meta-synthesis reinforces multiple levels of factors that influence the SRH of transgender individuals. These include limited information, lack of awareness, low socioeconomic status, stigma and discrimination, and social deprivation. Interventions are urgently needed to provide better sexual and reproductive well-being for transgender individuals.

Transgender women sex workers' experiences accessing sexual health care in Iran: a qualitative study.

BACKGROUND: This study aimed to examine the experiences of transgender women who work in the sex industry regarding their access to health care facilities for sexual health. Transgender women sex workers are recognised worldwide as a high-risk group for HIV and sexually transmitted infections (STIs). METHODS: In Iran, between January and May 2022, we employed a snowball sampling technique to recruit a diverse group of 22 transgender women sex workers aged 19-42 years. Semi-structured interviews were conducted with these participants to provide insights into their experiences with accessing sexual health care. RESULTS: The data was analysed using thematic analysis, revealing four overarching themes: experiences of violence, contextual barriers to health, socioeconomic challenges and HIV/STI risk practices, and 11 sub-themes. The results demonstrate that many participants experienced difficulties in accessing sexual health services due to violence, discrimination, financial difficulties and lack of awareness about STIs. CONCLUSION: Sex workers face extraordinarily challenging occupational risks, including sexual and physical abuse, mental health issues, and HIV and STIs. Targeted public intervention programs and research for this group are urgently needed. Outreach programs engaging with underserved transgender women sex workers have the potential to enhance access to healthcare services, and contribute to the reduction of HIV transmission rates.

Evaluation of the designed multi-epitope protein of Brucella melitensis in guinea pigs.

OBJECTIVES: One of the causes of human and animal zoonotic infections is Brucella melitensis, which is transmitted to humans through dairy products. It seems for prevention of human infection we might protect the livestock by an efficient protein as a vaccine candidate. For this purpose, the use of immunogenic proteins of bacteria is able to create immunity the same as the traditional vaccines. MATERIALS AND METHODS: In this study, by finding the immunogenic antigens of this bacterium by 2-dimensional gel electrophoresis and MALDI-TOF methods and also the proteins reported in other studies, we found the epitopes of the bacterial antigenic determinants in silico. Nineteen peptides of T and B epitopes were selected. They were ligated with linkers and after gene synthesis, the designed polypeptide was expressed in Escherichia coli BL21. The purified recombinant MEL protein mixed with chitin was injected subcutaneously into three 300 g male guinea pigs three times. Also, PBS control and Rev.1 commercial vaccine groups were considered. RESULTS: The results show that MEL polypeptide is equal to the Rev.1 vaccine in stimulating secretion of IFNγ and IL2 and specific IgG. High levels of IL-2 emphasize the activation of the cellular immunity, and in particular comparison of PI in guinea pig's spleen cells treated with recombinant MEL protein on days 0 and 5 show that it has significant proliferation compared with PBS unstimulated cells. CONCLUSION: This recombinant protein could be a subunit protein with sufficient efficiency in stimulating the humoral and cellular-mediated immune system against B. melitansis.

Comparison of depression, anxiety, stress, and related factors among women and men with human immunodeficiency virus infection.

AIMS: To compare depression, anxiety, stress, and related factors among women and men with human immunodeficiency virus (HIV) infection. SETTINGS AND DESIGN: In this cross-sectional survey conducted between November and September 2013, 200 participants with HIV/acquired immune deficiency syndrome (AIDS) attending Consultation Centers. MATERIALS AND METHODS: Participants with HIV/AIDS were interviewed using the Depression, Anxiety and Stress Scales questionnaire (DASS21 ). RESULTS: There were significant associations between marital status of women and the level of depression (P < 0.05). However, the mean depression and anxiety in women are greater than men (P < 0.05), and the mean stress in men is greater than women (P < 0.05). CONCLUSIONS: HIV infection is related with psychiatric disorders. According to the results, women are more vulnerable to depression and anxiety and they need more care. Management of these psychiatric disorders is very important and requires innovative comprehensive approaches.
