A prospective trial to evaluate the clinical efficacy and safety of neoadjuvant chemotherapy with arsenic trioxide and carboplatin in locally advanced cervical cancer: a study protocol for randomized controlled clinical
Full text linkBackground:
Cervical cancer is the fourth most common malignancy in women, which is threatening female reproductive tract health. Chemotherapy can be used for neoadjuvant therapy of locally advanced cervical cancer and postoperative adjuvant therapy for patients with high-risk factors, so as to reduce the focus, sensitize radiotherapy, and reduce recurrence. The current first-line treatment is paclitaxel combined with platinum. Many literature studies have found that As2O3 alone or in combination with platinum drugs have good efficacy in a variety of tumors both in vivo and in vitro. Moreover, our research group has verified that the efficacy of As2O3 combined with platinum drugs in the treatment of cervical cancer is not inferior to the traditional first-line regimen at the cellular and animal levels, and paclitaxel is more expensive than As2O3. Hence, we aim to evaluate the clinical efficacy and safety of neoadjuvant chemotherapy with As2O3 and carboplatin in locally advanced cervical cancer.
Methods:
Sixty participants in the IB2, IIA2, and IIB stages of cervical cancer will be recruited in this study. After excluding patients who did not meet the criteria, they were randomly assigned to two groups in a 1:1 ratio. All patients underwent colposcopic biopsies to confirm the diagnosis and detailed clinical examinations. Eligible patients will receive either 2 cycles of paclitaxel and carboplatin or As2O3 and carboplatin every 3 weeks. Patients were assessed for clinical efficacy after the second cycle of chemotherapy. Patients who had disease stable or disease progression at these time points will receive concurrent chemotherapy and radiation directly, while responders will receive PiverRutledge grade III radical hysterectomy and bilateral pelvic lymphadenectomy. Both groups of patients undergoing radical hysterectomy were given adjuvant therapy as per protocol-defined criteria. The efficacy and toxicity of the two groups were evaluated according to WHO acute and subacute toxicity classification standards.
Discussion:
This is the first single-center, prospective, two-arm design, open-label randomized control trial that will evaluate the clinical efficacy and safety of neoadjuvant chemotherapy with As2O3 and carboplatin in locally advanced cervical cancer
Male fertility under environmental stress: do polyamines act as pollen tube growth protectants?
Full text linkAlthough pollen structure and morphology evolved toward the optimization of stability and fertilization efficiency, its performance is affected by harsh environmental conditions, e.g., heat, cold, drought, pollutants, and other stressors. These phenomena are expected to increase in the coming years in relation to predicted environmental scenarios, contributing to a rapid increase in the interest of the scientific community in understanding the molecular and physiological responses implemented by male gametophyte to accomplish reproduction. Here, after a brief introduction summarizing the main events underlying pollen physiology with a focus on polyamine involvement in its development and germination, we review the main effects that environmental stresses can cause on pollen. We report the most relevant evidence in the literature underlying morphological, cytoskeletal, metabolic and signaling alterations involved in stress perception and response, focusing on the final stage of pollen life, i.e., from when it hydrates, to pollen tube growth and sperm cell transport, with these being the most sensitive to environmental changes. Finally, we hypothesize the molecular mechanisms through which polyamines, well-known molecules involved in plant development, stress response and adaptation, can exert a protective action against environmental stresses in pollen by decoding the essential steps and the intersection between polyamines and pollen tube growth mechanisms
Prevalence of sexually transmitted infections and associated risk behaviors in prisoners: A systematic review
Full text linkBackground and aims: Sexually transmitted infections (STIs) are one of the major health concerns globally. Generally, prisoners are at higher risks for STIs due to risk factors including; drug-use, high-risk sexual behaviors, densely populated prisons, and poor living conditions. Therefore, we aimed to conduct a systematic review to evaluate the existing data on STI prevalence, and its associated risk factors among prisoners.
Methods: We conducted a systematic search of the literature using the keywords in Scopus, PubMed, Web of Science, and Google Scholar online databases. We selected all the relevant original studies in English through title/abstract and full-text screening process..
Results: Based on the inclusion and exclusion criteria, we selected and reviewed 32 studies out of 96 identified papers. The most important STI-associated risk factors among prisoners were drug use, low educational levels, and unsafe sex. The prevalence of STIs was heterogenous in selected studies and was reported as follows; Human Immunodeficiency Virus (HIV) (0%-14.5%), hepatitis B viruses (HBV) (0.04%-27.23%), hepatitis C viruses (HCV) (0.17%-49.7%), Syphilis (0.2%-22.1%), Chlamydia Trachomatis (CT) (1.02%-6.7%), Gonorrhea (0.6%-7.8%), and herpes simplex virus-2 (HSV-2) 22.4%.
Conclusion: This systematic review indicates that the prevalence of STIs (HIV, HBV, HCV, Syphilis, Chlamydia Trachomatis, Gonorrhea, and HSV-2) among prisoners appears to be higher than the general population, with drug abuse, low educational levels, and unsafe sex as major risk factors
Determinants of menstrual hygiene management practices among schoolgirls: a cross-sectional study in the savannah region of Ghana
Full text linkIntroduction:
Menstruation is crucial in the reproductive lives of all women. The advent of menses in most settings is accompanied by physical and psychological health, religious, social, and cultural implications. The research intends to identify determinants of menstrual hygiene management (MHM) practices among adolescent girls in Junior High Schools in the West Gonja Municipality of the Savannah Region of Ghana.
Methods:
The study employed an analytical cross-sectional design with 430 adolescent schoolgirls selected through multistage sampling techniques. A structured questionnaire was used to collect data and analyzed using STATA version 14. A logistic regression model was run to determine the predictors of MHM practices.
Results:
The study discovered that 63.7% of the girls had sufficient knowledge of menstruation and menstrual hygiene. Almost all girls (97%) used some form of absorbent materials during menses, with over half of these girls (58.6%) using commercial sanitary pads, 30.5% using cloth, 3.7% using cotton, and 4.2% using tissue papers with 3.0% reported not using any absorbent material. Only 44.4% reported reusing their absorbent materials. Out of which, the majority (88.5%) of the schoolgirls cleaned their reusable absorbent material using soap and water with 77.5% drying absorbent materials in the sun. Overall, 84.9% practiced good MHM. Type of school [Adjusted Odds Ratio (AOR) =6.0; 95% Confidence Interval (CI) (2.64-13.59)], pocket money [AOR =2.5; 95% CI (1.27-4.86)], and residence [AOR =2.8 95% CI (1.55-5.18)] were the most significant determinants of menstrual hygiene management practice.
Conclusion:
About two-thirds of the schoolgirls are knowledgeable in menstrual hygiene but access to management materials is problematic whereas approximately half of the girls have access to sanitary pads and the rest resort to the use of cloth and cotton. Pocket money and residential status were the most important predictors of the menstrual hygiene management. The government initiative to provide schoolgirls with sanitary pads could go a long way to improve menstrual hygiene management if implemented across all schools in Ghana, particularly in rural areas
Significance of triple detection of p16/ki-67 dual-staining, liquid-based cytology and HR HPV testing in screening of cervical cancer: a retrospective study
Full text linkIn addition to liquid-based cytology (LBC) and HR HPV testing, p16/ki-67 dual-staining is another method for cervical cancer screening. The combination of any two methods can improve the accuracy of screening, but some cervical lesions are still missed or misdiagnosed. In this retrospective study, the significance of LBC, HR HPV testing and especially p16/ki-67 dual-staining in cervical lesion screening was evaluated with reference to histological diagnosis. At the same time, we tried to explore the value of p16/ki-67 dual-staining combined with LBC and HR HPV testing (triple detection) in improving the diagnostic specificity of CIN2+ and reducing the missed diagnosis of CIN2+ lesions. We found that p16/ki-67 dual-staining was valuable in identifying cervical CIN2+ lesions and reducing the missed diagnosis of CIN2+ in HPV negative patients. More than 96% of CIN2+ patients were positive for two or three tests of triple detection. Whole positive triple detection can effectively predict high grade cervical lesions. In conclusion, the triple detection can distinguish almost all cervical CIN2+ lesions. Our data put forward and highlight the feasibility and significance of triple detection in cervical lesion screening
Menstrual irregularity and its associated factors among college students in Ethiopia, 2021
Full text linkBackground: Menstrual irregularity can occur at any age, but it is most common among women under the age of 23 years. Menstrual irregularity is a foremost gynecological problem and a cause of anxiety to students and those close to them. These students experience monthly absenteeism, premenstrual symptoms, and a lack of concentration due to menstrual problems, all of which interfere with their education. Therefore, this study aimed to assess the magnitude of menstrual irregularity and associated factors among college students in Debre Berhan Town, North Shewa, Amhara Regional State, Ethiopia, in 2021.
Methods: An institution-based cross-sectional study was conducted from June to July 2021 in Debre Berhan town. Data was collected using self-administered questionnaires in 420 eligible female college students by systematic random sampling technique. Weight and height were measured and Body Mass Index (BMI) was calculated after data collection. Each questionnaire was checked for completeness, cleaned, coded, entered into EPI-DATA, and then transported to SPSS software. Bi-variable and multivariable logistic regression analyses were employed to determine the association of each independent variable with the dependent variable. P ≤ 0.05 were used to declare association and select predictors.
Results: In the current study, 395 students participated with a response rate of 93.6%. Of all the total respondents, the magnitude of menstrual cycle irregularity was 33.4% (95% CI 28.6-38.2). Age < 20 years old [AOR = 3.88, 95% CI (1.25-12.18)], age of menarche ≤ 12 years [AOR = 4, 95% CI (1.18-13.9), sleeping hours ≤ 5 h [AOR= 2.26, 95% CI (1.04-4.93)], perceived stress [AOR = 2, 95% CI (1.53-3.23)] and being overweight [AOR = 2, 95% CI (1.13-3.23) were the variables significantly associated with the magnitude of menstrual irregularity.
Conclusion and recommendation: This study shows that more than one-third of the college students in Debre Berhan town have experienced menstrual irregularity. Being less than 20 years old, having a history of early menarche, being overweight, and perceived stress were a variable significantly associated with menstrual irregularity. To control menstrual irregularity, girls should control their weight and lead a healthy lifestyle, including getting adequate sleep which could be aided by training on time management
Changing preferences for a cervical cancer screening strategy: moving away from annual testing
Full text linkBackground:
While annual cytology has not been recommended for many years, it remains many patients' preferred screening strategy for cervical cancer. Patient education and provider recommendations have been found effective in aligning professional society guidelines with patient preferences. We assessed whether an educational video with value elicitation exercises (utility assessments) changed screening strategy preferences among patients who had an initial preference for annual screening.
Materials and Methods:
We conducted an interventional study of English- or Spanish-speaking women 21–65 years of age, recruited from two women's health clinics in San Francisco, California (n = 262). Participants were asked about their preferred method of screening before viewing a 7-minute educational video and using a computerized tool that elicited values for 23 different health states related to cervical cancer screening. Directly afterward, they were again asked about their preferred screening strategy. Multivariable regression analysis was utilized to identify independent predictors of changing preferences.
Results:
Of 246 enrollees, 62.6% (154/246) had an initial preference for annual cytology; after viewing the video and completing the values elicitation exercises, about half (72/154, 47%) preferred a strategy other than annual screening. Having attended college and being screened every 3 to 5 years in the recent past were independent predictors of changing preferences away from annual screening. In sensitivity analyses, 53.2% of average-risk participants changed preferences away from annual cytology (p < 0.01).
Conclusions:
Viewing an educational video and conducting a series of value elicitation exercises were associated with a substantially decreased likelihood of preferring annual screening. These findings underscore the importance of patient-centered education to help support informed patient preferences
Access to sexual health services and support for people with intellectual and developmental disabilities: an Australian cross-sector survey
Full text linkIntroduction:
People with intellectual and developmental disabilities under the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) have the right to access sexual health services including information, education, and support. Little is known about the capacity of sexual health professionals to provide these services.
Methods:
Using an observational research design, this study utilised a descriptive survey tool (PASH–Ext) that also encompassed a standardised measure, with a cross-sectional purposive sample of 52 Australian sexual health professionals. Data was collected in 2020.
Results:
Just over half of the participants reported having received training in their preservice education to work with people with intellectual and developmental disabilities, of these 60% held the view that people with intellectual and developmental disabilities would not feel embarrassed receiving sexual health information and support.
Conclusion:
The study found that training is both important to the professionals’ preparedness to work with people with intellectual and developmental disabilities, and that these professionals advocate for the continuation of this training in pre-service courses and additional training in post service education for sexual health workers.
Policy Implications:
To progressively realise Article 25 of the UNCRPD signatory, countries need to ensure sexual health services are accessible to people with intellectual and developmental disabilities. This study recommends that sexual health policy addresses equity of access for people with intellectual and developmental disability by ensuring all staff are prepared and supported to provide these services
The relationship between parametrial involvement and parametrial tissue removed in radical surgery in early-stage cervical cancer
Full text linkBackground:
The study aims to evaluate the effect of parametrial dimensions on the prognosis of cases who underwent type 3 radical hysterectomy or radical trachelectomy in early-stage cervical cancer (stage I - IIa).
Methods:
Medical reports of patients with early-stage cervical cancer who have undergone surgery between 1998 and 2020 in Akdeniz University Faculty of Medicine Gynecological Oncology Clinic were reviewed retrospectively. A total of 292 cases were identified and included in the study. Demographic characteristics, preoperative examination findings, operation records, and pathology results of the cases were reviewed.
Results:
Parametrial involvement was found histopathologically negative in 244 out of 292 patients included in our study, the remaining 48 (16.4%) patients were found to be positive. The mean length of the right and left parametrium in the group with negative parametrium invasion, who had an average follow-up of 131.2 (0.57 - 268.2) months, was 3 cm, while the mean volume of the right and left parametrium was 7.2 (0.52 - 32) cm3 and 6 (0.48 - 34) cm3, respectively. On the other hand, the mean length of the right and left parametrium was 3 (1.5 - 5.5) cm and 3 (1.4 - 7) cm, respectively, while the mean volume of the right parametrium was 5.55 (1.37 - 22) cm3, and the mean volume of the left parametrium was 7.5 (1.35 - 24) cm3 in 48 patients with positive parametrial invasion. No statistically significant difference was detected between the two groups when compared in terms of parametrial sizes and volumes (P values of 0.061, 0.262, 0.391, and 0.468, respectively).
Conclusions:
Radical surgical approach is necessary to obtain a tumor-free surgical margin in the surgical treatment of early cervical cancer, but the complications leading to morbidity and mortality are also increasing with this radicality. For this reason, we consider that it is important to adapt the dimensions of the removed parametrium according to the factors affecting recurrence in cervical cancer to obtain more appropriate surgical margins with the least complications
Associations between anabolic-androgenic steroid use and sexual health behaviors among adolescent boys: results from the 2019 youth risk behavior survey
No full textThe aim of this study was to determine the association between lifetime anabolic-androgenic steroid (AAS) use and seven indicators of sexual health behaviors among a nationally representative sample of adolescent boys in the United States. Multiple modified Poisson regression analyses were conducted to determine the associations between any lifetime AAS use and seven indicators of sexual health behaviors among 2,095 sexually active adolescent boys from the 2019 National Youth Risk Behavior Survey. Sexually active boys who reported lifetime AAS use were at greater risk of having sexual intercourse before the age of 13 years (adjusted risk ratio [aRR] = 2.73, 95% confidence interval [CI] = [1.44, 5.17]), reporting ≥4 sexual partners in their lifetime (aRR = 1.96, 95% CI = [1.34, 2.89]) and in the past 3 months (aRR = 6.77, 95% CI = [3.19, 14.37]), having been tested for HIV in their lifetime (aRR = 2.49, 95% CI = [1.13, 4.73]), and having been tested for any sexually transmitted infection in the past 12 months (aRR = 3.14, 95% CI = [1.63, 6.03]). These findings align with prior research among adult men and have implications for public health and health care prevention efforts to reduce the use of AAS, as well as support the engagement in safe sexual health behaviors among adolescent boys
