Knowledge and attitudes of healthcare professionals working in a training and research hospital on early diagnosis of cervical cancer (a Somalia example): cross-sectional study.

BACKGROUND: Despite the early diagnosis and treatment of cervical cancer, it is still a significant public health problem in Somalia. This study was conducted to evaluate the knowledge and attitudes of healthcare professionals towards the early diagnosis of cervical cancer. METHODS: This study was conducted in Mogadishu, the capital of Somalia, between December 2020 and February 2021. The cross-sectional study consisted of a total of 280 healthcare professionals. The study data was collected using a questionnaire consisting of 38 questions evaluating the knowledge and attitudes of all healthcare professionals towards the early diagnosis of cervical cancer, an additional 15 questions for women only, and a total of 43 questions. RESULTS: 22.1% of the participants received cervical cancer training during vocational education and training. Cervical cancer education after graduation is 16.8%, and the rate of providing education to patients is only 29.6%. The rate of female healthcare professionals having a Pap smear test is 2%. The participants' cervical cancer total knowledge score was 16.5 ± 6.69, and the success rate was 63.46. The highest success rate in knowledge subgroup questions was HPV questions with 69.6. A statistically significant difference was found between the participants' profession, training on the subject during their vocational education, and total knowledge scores (p < 0.001). When the knowledge question subscales were compared, a significant difference was found between participants' gender and HPV questions subscale score (p = 0.028). A statistically significant difference was found between the participants' professions, receiving training on the subject during vocational training, and all subscales (p < 0.05). A statistically significant difference was found between the participants' income status and risk factors questions scores (p = 0.026). CONCLUSION: This study shows that the knowledge and training of healthcare professionals working in a training and research hospital in Somalia for early cervical cancer diagnosis are not sufficient. In addition, it reveals that female healthcare professionals have almost no Pap smears. Therefore, studies and training should be planned to train all healthcare professionals, especially female healthcare professionals, and overcome all possible obstacles to the acceptance of the screening tests by women.

Apparent differences between single layer molybdenum disulphide fabricated via chemical vapour deposition and exfoliation.

Innovative applications based on two-dimensional solids require cost-effective fabrication processes resulting in large areas of high quality materials. Chemical vapour deposition is among the most promising methods to fulfill these requirements. However, for 2D materials prepared in this way it is generally assumed that they are of inferior quality in comparison to the exfoliated 2D materials commonly used in basic research. In this work we challenge this assumption and aim to quantify the differences in quality for the prototypical transition metal dichalcogenide MoS2. To this end single layers of MoS2 prepared by different techniques (exfoliation, grown by different chemical vapour deposition methods, transfer techniques and as vertical heterostructure with graphene) are studied by Raman and photoluminescence spectroscopy, complemented by atomic force microscopy. We demonstrate that as-prepared MoS2, directly grown on SiO2, differs from exfoliated MoS2 in terms of higher photoluminescence, lower electron concentration and increased strain. As soon as a water film is intercalated (e.g. by transfer) underneath the grown MoS2, in particular the (opto)electronic properties become practically identical to those of exfoliated MoS2. A comparison of the two most common precursors shows that the growth with MoO3 causes greater strain and/or defect density deviations than growth with ammonium heptamolybdate. As part of a heterostructure directly grown MoS2 interacts much stronger with the substrate and in this case an intercalated water film does not lead to the complete decoupling, which is typical for exfoliation or transfer. Our work shows that the supposedly poorer quality of grown 2D transition metal dichalcogenides is indeed a misconception.

The effects of atypical antipsychotic usage duration on serum adiponectin levels and other metabolic parameters.

OBJECTIVE: Although atypical antipsychotics are well-tolerated and effective treatment options for schizophrenia, they have metabolic side effects, including weight gain and increased risk of Type II Diabetes Mellitus (DM). Adiponectin, produced exclusively in adipocytes, is the most abundant serum adipokine. Low levels of adiponectin are correlated with DM, insulin resistance and coronary heart disease. Usage of atypical antipsychotics may create a risk of metabolic syndrome. The aim of this study was to evaluate the effects of antipsychotic usage on parameters related to development of metabolic syndrome. MATERIALS AND METHODS: A total of 27 patients (n=27) (13 women and 14 men) were recruited from our out-patient psychiatry clinic. All patients had been treated with atypical antipsychotics for at least 3 months and were in remission. Patients were evaluated for levels of HDL (High Density Lipoprotein), LDL (Low Density Lipoprotein), TG (Triglyceride) total cholesterol and fasting blood glucose, body weight, BMI (Body Mass Index), waist circumference and serum adiponectin levels. RESULTS: Serum adiponectin levels were significantly lower (p:0.000) and body weights were significantly higher (p:0.003) in the patients who had been using atypical antipsychotics for longer than a year in comparison to patients who had been using atypical antipsychotics for one year or less. CONCLUSION: Our findings supported the hypothesis that the length of administration of atypical antipsychotics has an effect on metabolic changes. They also highlight the fact that when investigating metabolic changes generated by atypical antipsychotic effects, the length of time that the patient has been on the atypical antipsychotics should also be considered.
