ABSTRACT

BACKGROUND: Gender-based violence is a major public health concern arising from the structural discrimination of women and girls. In 2014, Ecuador criminalized acts of femicide in response to a growing crisis across the region. As no epidemiological studies on the state of female homicides and femicides have been published, we estimated patterns of female homicides and femicides nationally and the burden through economic cost per years of life lost, between 2001 and 2017.

METHODS: Using aggregated data from the National Institute of Census and Statistics and police records we estimated the annual mortality rates, cumulative incidence and prevalence odds ratios for female homicides and femicides, from 2001 to 2017. The impact of aggressions, assaults and violence on years of life lost due to premature mortality was estimated using the Human Capital method.

RESULTS: Over the period, at least 3236 cases of female homicides and femicides were reported. The highest murder rate occurred in the province of Sucumbíos (6.5 per 100,000) and in the Putumayo canton (12.5 per 100,000). The most common way to murder their victims was using firearms (38%). The highest odds ratio was estimated for women aged between 25 and 29, at 4.5 (3.9-5.1), of primary school attainment at 17.2 (14.6-20.3) and of Afro-Ecuadoran descent 18.1 (10.5-30.9). Female homicide-related costs reached, on average, $35 million per year and more than $500 million lost from 2001 to 2017.

CONCLUSIONS: The high rates, distribution and cost indicate that investments are urgently needed to address the structural causes and reduce the impact of female homicides and femicides in Ecuador; thereby protecting the livelihood and well-being of their women and girls.

ABSTRACT

This cross-sectional study aimed to quantitatively analyze the optical coherence tomography angiography (OCTA) images using MATLAB-based software and evaluate the initial changes in macular vascular density and the distortion of the foveal avascular zone (FAZ), before the clinical appearance of diabetic retinopathy. For this purpose, 21 diabetic patients without any clinical features indicating DR, and 21 healthy individuals matched with patients based on their demographic characteristics were included. Macular thickness, macular vascular density, and morphological changes of FAZ were assessed using OCTA. The diagnostic ability of morphological parameters was evaluated by receiver operating curve analysis. The intraclass correlation coefficient (ICCC) index was used to check the consistency of the extracted values. There was no significant difference in age, gender, LogMAR visual acuity, spherical equivalent, and intra-ocular pressure amongst patients and controls. No correlation was found between age and the FAZ area as well as vascular density. The vascular structure of the superficial layer showed FAZ enlargement, reduced vascular density in the macular area, and significant deviations of FAZ shape parameters (convexity and Frequency Domain Irregularity) in patients compared with healthy individuals. Measurements were highly correlated between separate imaging sessions with ICCC of over 0.85 for all parameters. The represented data suggests that radiomics parameters can be applied as both an early screening tool and guidance for better follow-up of diabetic patients who have not had any sign of DR in fundoscopic exams.

ABSTRACT

BACKGROUND: The present study investigated the prevalence of osteoporosis (OP) among patients with essential hypertension (EH) in the Changchun community and analysed the correlation between EH and OP.

METHODS: The study included 425 subjects with EH and 425 age- and sex-matched healthy controls. Bone mineral density (BMD) and serum creatinine (CR) levels were measured, and the subjects’ current EH and OP statuses were surveyed to analyse the correlation between EH and OP.

RESULTS: The EH group exhibited lower BMD and a higher rate of having OP than the control group, and this difference was statistically significant (p < 0.05). A significant sex difference in the BMD T-score was observed among the subjects (male: – 1.19 ± 1.55, female: – 1.70 ± 1.34). In both the EH group and the control group, the rate of having OP in females was greater than that in males. However, the OP prevalence among subjects with EH varied significantly by age, body weight, fracture history, nocturnal urination frequency, depression and anxiety status, duration of hypertension, and antihypertensive medication use (p < 0.05). Two-way analysis of variance suggested an effect of the interaction between different EH statuses and bone mass conditions on the serum CR values (F = 3.584, p = 0.028, bias η² = 0.008).

CONCLUSIONS: The prevalence of OP and low BMD were significantly higher among subjects with EH than among healthy controls. Additionally, the findings indicate that age, weight, fracture history, nocturnal urination frequency, depression and anxiety, duration of hypertension and antihypertensive drug use may be correlated to having OP in EH subjects, requiring further studies. Moreover, serum CR levels in subjects with different bone mass profiles were strongly influenced by the presence or absence of EH, and the serum CR levels differed significantly with the interaction of these two factors.

ABSTRACT

BACKGROUND: Discrimination due to gender and ethnicity has been found to be widespread in medicine and healthcare. Swedish and European legislation list seven discrimination grounds (age, sex, ethnicity, religion, sexuality, non-binary gender identity, and disability) which may intersect with each other; yet these have only been sparsely researched. The aim of this study was to assess the extent of discrimination, based on these seven discrimination grounds, amongst final-year medical students in Sweden.

METHODS: A web-based survey, based on the CHERRIES-checklist, was disseminated to course coordinators and program directors in charge of final year medical students at all seven medical schools in Sweden. Quantitative data were analyzed using descriptive statistics, Fisher’s exact test, and logistic regression. Free-text answers were analyzed thematically using the “Master Suppression techniques” conceptual framework.

RESULTS: Of the 1298 medical students contacted, 247 (19%) took part in the survey. Almost half (n = 103, 42%) had experienced some form of discrimination, and this difference was statistically significant by gender (p = 0.012), self-perceived ethnicity (p < 0.001), country of birth other than Scandinavia (p < 0.001) and visible religious signs (p = 0.037). The most common type of discrimination was gender-based (in 83% of students who had experienced discrimination), followed by age (48%), and ethnicity (42%). In the logistic regression, women/non-binary gender (p = 0.001, OR 2.44 [95% CI 1.41-4.22]), country of birth not in Scandinavia (p < 0.001, OR 8.05 [2.69-24.03]), non-Caucasian ethnicity (p = 0.04, OR 2.70 [1.39-5.27]), and disability (p = 0.02, OR 13.8 [1.58-12040]) were independently associated with discrimination. Half of those who had experienced religion-based discrimination and nearly one-third of victims of ethnicity-based discrimination reported “large” or “extreme” impact of this. Clinical staff or supervisors were the most common offenders (34%), closely followed by patients and their relatives (30%), with non-Caucasian respondents significantly more likely to experience discrimination by patients (p < 0.001).

CONCLUSIONS: Discrimination appears to be frequent in medical school, even in one of the world’s “most equal countries”. Discrimination is most commonly gender- or ethnicity-based, with ethnicity- and religion-based discrimination appearing to have the largest impact. Future research should continue to evaluate discrimination from an intersectional perspective, adapted for local contexts and legislations.

ABSTRACT

BACKGROUND: In May 2018, following the preliminary results of a study in Botswana that reported congenital anomalies in babies born to HIV-positive women taking dolutegravir drug, the WHO issued a teratogenicity alert. However, there are scarce data on the impact of this guidance on contraceptive uptake among women taking dolutegravir. We assessed the uptake of contraceptives in HIV-positive women of reproductive age on dolutegravir regimens.

METHODS: We conducted a cross-sectional survey from April 2019 to July 2019 in five government health facilities in central Uganda, where dolutegravir-based regimens were offered as the preferred first-line antiretroviral treatment. We randomly selected 359 non-pregnant women aged 15-49 years taking dolutegravir-based regimens and interviewed them using semi-structured interviewer-administered questionnaires. We collected data on demographics, contraceptive use, individual, social, and health system factors. We described patients’ characteristics using descriptive statistics and assessed factors associated with contraceptive uptake using a modified Poisson regression model.

RESULTS: A total of 359 women were included in the study. The mean age was 37 years (standard deviation = 6.8) and overall contraceptive uptake was 38.4%. The most utilized method was injectable method at 58.4% followed by condoms (15%), intrauterine device (10.7%), pills (6.4%), implants (5.4%), and sterilization (0.7%). Predictors for contraceptive uptake were parity of 3-4 children (Adjusted Prevalence Ratio (APR) = 1.48, 95% confidence interval (CI): 1.14, 1.92) in reference to those with 1-2 children. There was reduced contraceptive uptake in women of the age range 40-49 years (APR = 0.45, CI: 0.21-0.94) compared to those aged 15-24 years. Unemployed women were less likely to use contraceptives (APR: 0.6, CI: 0.42- 0.94) than the formally employed. Contraceptive uptake was lower among women who did not discuss family planning with their partners (APR = 0.39, CI: 0.29-0.52) than those who discussed family planning with their partners and women who did not receive family planning counseling (APR = 0.56, CI: 0.34-0.92) than those who received family planning counselling.

CONCLUSION: We observed a low-level uptake of contraceptives, with injectables as the most used method. Family planning counseling and partner discussion on family planning were associated with contraceptive uptake among the women who used dolutegravir-based regimens. There is a need for more strategies to integrate FP services and increase male involvement in HIV care programs.

ABSTRACT

BACKGROUND: There is no other better way to safeguard an infant’s health in the first 6 months of life than exclusive breastfeeding (EBF). Breast milk is valuable in all aspects of an infant’s physical and mental growth as well as immune development. The study aimed to assess the prevalence and factors associated with EBF practice among HIV-infected mothers in the Southern Highlands of Tanzania.

METHOD: A hospital-based analytical cross-sectional study was conducted among lactating HIV-infected mothers. A random sampling procedure was used to obtain 372 HIV-infected mothers of infants from 6 to 12 months of age who were still breastfeeding at the time of data collection. An interviewer-administered structured questionnaire was used for data collection. Bivariate and multivariable logistic regression was used to assess factors associated with EBF practice. Statistical package for social science (SPSS volume 20) software was used for data entry and analysis.

RESULTS: The prevalence of EBF practice was 58.1% at 95% Confidence Interval of 52.9% to 63.1%. More than half of the respondents 199 (53.5%) had adequate knowledge while 173(46.5%) had inadequate knowledge about EBF. After adjusting for confounders, factors associated with EBF practice were knowledge about EBF [Adequate knowledge (AOR = 5.11 at 95% CI 3.2-8.17, p < 0.001)], ANC visits [Adequate (AOR = 1.76 at 95% CI 1.09-2.82, p = 0.002)], Income per day [1 0r more USD (AOR = 1.83 at 95% CI 1.14-2.94, p = 0.013)], positive perception of EBF [ positive perception (AOR = 3.51 at 95% CI 2.25-5.47, p < 0.001) and having ever experienced a breast problem AOR = 3.91 at 95% CI 1.89-8.08, p < 0.001.

CONCLUSION: More than half of interviewed mothers with HIV practiced EBF. The EBF practice among HIV lactating mothers was significantly influenced by adequate knowledge of EBF, positive perception toward EBF, adequate ANC visits, and having never experienced breast problems. Strengthening adherence to ANC routine visits, counseling on breastfeeding, and improving mothers’ knowledge about exclusive breastfeeding would contribute to the enhancement of EBF practice in this region. An innovative interventional study is recommended to develop more effective strategies to improve EBF knowledge and practice among HIV-infected mothers.

ABSTRACT

BACKGROUND: Asthma is a chronic inflammatory disease of the airways that causes recurring episodes of wheezing, breathlessness, chest tightness and coughing. Inhaled drugs on a daily basis are the cornerstone of asthma treatment, therefore, patient adherence is very important.

METHODS: We performed a multicenter, open, non-interventional, observational, prospective study of 716 adult patients diagnosed with asthma receiving FDC (Fixed-dose combination) budesonide/formoterol via the Elpenhaler device. We assessed the adherence to treatment at 3 and 6 months (based on the MMAS-8: 8-item Morisky Medication Adherence Scale), the quality of life and change in forced expiratory volume in 1 s (FEV1) from baseline to follow-up.

RESULTS: Approximately 80% of the patients showed medium to high adherence throughout the study. The mean (SD) MMAS-8 score at 6 months was 6.85 (1.54) and we observed a statistically significant shift of patients from the low adherence group to the high adherence group at 6 months. Moreover, after 6 months of treatment with FDC budesonide/formoterol, we observed an increase in the patients’ quality of life that as expressed by a change 2.01 (95%CI 1.93-2.10) units in Mini AQLQ (p < 0.0001) that was more pronounced in the high adherence group. The same trend was also observed in terms of spirometry (mean FEV1 2.58 L (0.85) at the end of the study, increased by 220 mL from baseline) with a higher improvement in the medium and high adherence groups.

CONCLUSIONS: Treatment with FDC of budesonide/formoterol via the Elpenhaler device was associated with improvement in asthma-related quality of life and lung function over 6 months that were more prominent in patients with higher adherence.

ABSTRACT

PURPOSE: Smoking cessation in patients with diagnosed lung cancer has positive effects on cancer therapy and overall prognosis. Despite this, knowledge on smoking cessation in lung cancer patients is sparse.

METHODS: This is an observational single centre, 12-week, prospective, single-arm trial at a tertiary lung cancer centre. Responsive patients were enrolled following confirmed lung cancer diagnosis. Smoking cessation intervention included counselling as well as pharmacotherapy. The primary endpoint was the point prevalence abstinence rate at week 12 based on biochemical verification. Secondary endpoints were the abstinence rate at week 26, quality of life and side effects.

RESULTS: 80 patients were enrolled. Mean age was 62.6 ± 7.9 years. Most patients (63%) were treated with chemotherapy or radiochemotherapy. 39 patients used nicotine replacement therapy, 35 varenicline whereas six patients did not use pharmacotherapy. During the study period 13 patients died. Data were available in 72 patients after 12 weeks and 57 patients at week 24. Point prevalence abstinence rates were 37.5% (95% CI 26.4-49.7%) at week 12 and 32.8% (95% CI 21.8-45.4%) at week 26, respectively. Quality of life and side effects were not significantly affected by pharmacotherapy.

CONCLUSION: In conclusion, our results suggest that smoking cessation is feasible in patients with newly diagnosed lung cancer. The observed abstinence rate is comparable to other patient cohorts. Furthermore, pharmacotherapy in addition to cancer therapy was safe and did not show novel side effects in these seriously ill patients. Thus, smoking cessation should be an integral part of lung cancer treatment. Trial registration The study was conducted in accordance with good clinical practice standards (GCP) and approved by the local ethics committee (16/3/14), the European PAS registry (EUPAS8748) and the German BfArM (NIS-Studien-Nr. 5508). All patients provided written informed consent before study enrollment.

ABSTRACT

BACKGROUND: Despite the observed decrease in female genital mutilation (FGM) prevalence, it is increasingly being medicalized. We examined the attitudes of both parents towards the FGM practice in Egypt, and highlighted the effect of fathers’ decision making and attitudes towards FGM and violence on FGM practice and medicalization.

METHODS: This study is a secondary analysis of Egypt Health Issues Survey (EHIS), 2015. The 2015 EHIS involved a systematic random selection of a subsample of 614 Shiakhas/villages out of the 884 shiakhas/villages that had been chosen as Primary Sampling Units in the 2014 EDHS. Descriptive statistics of the study sample and parents’ attitudes was performed. Three indices were created describing; mothers’ and fathers’ attitudes towards FGM, decision making and rejecting violence against women. Bivariate and multivariable analyses were conducted to identify predictors of FGM practice and medicalization.

RESULTS: A considerable proportion of EHIS girls; 16.4% were circumcised and 36% of girls were expected to be circumcised. More than two thirds of circumcised girls were circumcised by a physician; namely 67% and 13.5% by nurses. The majority of mothers (88.4%) and fathers (84.8%) believed that FGM practice should continue. They believed that FGM is a religious obligation (72.3% of mothers and 73% of fathers). Parents believed that husbands prefer a circumcised wife (81.1% and 82.5% of mothers and fathers respectively). Being in the poorest wealth quintile (OR = 4.2, p < 0.001) and living in rural Upper Egypt (OR = 4.55, p < 0.001) were the predictors of FGM practice, while medicalization was more likely among the rich and educated parents. Parents’ attitudes supporting FGM was significantly associated with its practice (OR = 1.97, p < 0.001, for mothers and OR = 1.27, p < 0.001, for fathers). Rejecting violence against women was associated with less likelihood of practicing FGM (OR = 0.89, p < 0.05) and more likelihood of its medicalization (OR = 1.25, p < 0.01).

CONCLUSION: More attention should be paid to enforce the laws against FGM practice by health care providers. Raising the community awareness on girls’ human rights and elimination of FGM practice which is a severe form of violence against women and gender inequality in sexual rights should be prioritized with targeting men in FGM programs.

ABSTRACT

BACKGROUND: Facet tropism (FT) can be defined as the angular difference between the orientation of the right and left facet joints in axial or sagittal planes. Most studies discuss about the relationship with lumbar disc hernia and facet joint angle. However, little is known about the association of facet tropism with disc herniation in the cervical spine in multisports athletes. In this study, We aimed to investigate the relationship between cervical facet tropism and disc hernia in athletes of different branches between the ages of 20-40 from the cervical MR images of the cases.

METHODS: This is a retrospective study performed on athletes who applied our hospital between January 2014-2019 with neck pain and have MR imaging of the cervical spine. Cervical MR images of the patients were evaluated by an experienced radiologist from the hospital system database and archives. 79 cases (52 men and 27 women) were included in the study.

RESULTS: No statistically significant difference was found between the facet joint angles of both groups at all levels (p˃0.05). Only left C6-7 disc angles of CDH group were measured as 92.99° ± 10.77⁰ (62⁰-113⁰) and 88.58° ± 7.65° (67°-110°) for the normal group and this difference was found statistically significant (p = 0.007).

CONCLUSION: In this study, we did not predict that cervical facet tropism may be a factor associated with cervical disc hernia in young athletes with CDH.
