e17520 Background: To determine if there is association between the clinical-pathological characteristics and the development of bone metastases in patients with prostate cancer treated in Oncosalud during the period 2016-2018. Methods: An observational, analytical, cross-sectional and retrospective study was conducted in 386 men diagnosed with prostate cancer in a Private Clinic in Peru. We presented descriptive and analytic analysis to identify variables associated with bone metastases; in addition, odds ratios were estimated. Results: In reference to the PSA groups, those patients with PSA values higher than 20 ng / ml presented a risk 9.69 times higher to develop bone metastases (95% CI: 5.08-18.45). In regard to Gleason groups, those with a 9-10 score presented a risk of bone metastasis 2.67 times higher than patients with lower Gleason score (95% CI: 1.31-5.45). In regard to the clinical stage, those patients with a T3 stage had a 6.77 higher risk than those with lower clinical stages (95% CI: 3.79-12.09). Conclusions: Clinical-pathological characteristics associated with bone metastasis were identified in patients with prostate cancer, including age, Gleason scale, PSA value and clinical T stage.

BACKGROUND Morbidity and mortality in HIV disease is due to immune-suppression leading to life-threatening opportunistic infections (OIs) during the natural course of the disease. In 2015, the HIV prevalence is low in general population and concentrated among key populations. OBJECTIVE This study aimed to assess the prevalence and CD4 correlates of OIs among adult HIV-infected patients attending antiretroviral health care in Morocco, during 2015. METHODS We conducted a cross-sectional survey among all adult PLHIV for admitted in the health care centers during 2015, who had acquired infection disease. Patients’ opportunistic infection status was determined through clinical diagnosis and laboratory investigations. CD4 count was determined using flow cytometry technique. The clinical stage of HIV was identified by the classification of Centers for Disease Control and Prevention (CDC). We collected Socio-demographic and clinical data from patients’ medical records. We performed statistical analysis by using Epi-Info 7.2.0.1 software. The appropriate test was applied, bivariate analysis was made and the differences were significant when p<.05. RESULTS 299 HIV-infected cases were included; 53% were males. The most represented age group was 25-34 years (36.1%). The mean age of the cases was 38.7 ± 16.8. The prevalence of OIs was 47.8%. Tuberculosis (65/299, 21.7%), Pneumocystis jiroveci pneumonia (40/299, 13.4%) and Oral candidiasis (22/299, 7.4%) were the most frequently observed OIs. CONCLUSIONS Tuberculosis, pneumocystis and oral candidacies were the leading OIs, encountered by HIV-infected cases. Preventive measures and early diagnosis of HIV associated to OIs are crucial.

To date, most network research contains one or more of five major problems. First, it tends to be atheoretical, ignoring the various social theories that contain network implications. Second, it explores single levels of analysis rather than the multiple levels out of which most networks are comprised. Third, network analysis has employed very little the insights from contemporary complex systems analysis and computer simulations. Foruth, it typically uses descriptive rather than inferential statistics, thus robbing it of the ability to make claims about the larger universe of networks. Finally, almost all the research is static and cross-sectional rather than dynamic. Theories of Communication Networks presents solutions to all five problems. The authors develop a multitheoretical model that relates different social science theories with different network properties. This model is multilevel, providing a network decomposition that applies the various social theories to all network levels: individuals, dyads, triples, groups, and the entire network. The book then establishes a model from the perspective of complex adaptive systems and demonstrates how to use Blanche, an agent-based network computer simulation environment, to generate and test network theories and hypotheses. It presents recent developments in network statistical analysis, the p* family, which provides a basis for valid multilevel statistical inferences regarding networks. Finally, it shows how to relate communication networks to other networks, thus providing the basis in conjunction with computer simulations to study the emergence of dynamic organizational networks.

BackgroundA large number of international migrants in Malaysia face challenges in obtaining good health, the extent of which is still relatively unknown. This study aims to map the existing academic literature on migrant health in Malaysia and to provide an overview of the topical coverage, quality and level of evidence of these scientific studies.MethodsA scoping review was conducted using six databases, including Econlit, Embase, Global Health, Medline, PsycINFO and Social Policy and Practice. Studies were eligible for inclusion if they were conducted in Malaysia, peer-reviewed, focused on a health dimension according to the Bay Area Regional Health Inequities Initiative (BARHII) framework, and targeted the vulnerable international migrant population. Data were extracted by using the BARHII framework and a newly developed decision tree to identify the type of study design and corresponding level of evidence. Modified Joanna Briggs Institute checklists were used to assess study quality, and a multiple-correspondence analysis (MCA) was conducted to identify associations between different variables.Results67 publications met the selection criteria and were included in the study. The majority (n=41) of studies included foreign workers. Over two-thirds (n=46) focused on disease and injury, and a similar number (n=46) had descriptive designs. The average quality of the papers was low, yet quality differed significantly among them. The MCA showed that high-quality studies were mostly qualitative designs that included refugees and focused on living conditions, while prevalence and analytical cross-sectional studies were mostly of low quality.ConclusionThis study provides an overview of the scientific literature on migrant health in Malaysia published between 1965 and 2019. In general, the quality of these studies is low, and various health dimensions have not been thoroughly researched. Therefore, researchers should address these issues to improve the evidence base to support policy-makers with high-quality evidence for decision-making.

This study focused on the middle-pressure jet grouting method, which has a complicated development mechanism for the columnar soil-improved body, with the aim of establishing a computer-aided engineering (CAE) system that can simulate the performance on a computer. Furthermore, in order to confirm the effect of middle-pressure jet grouting with mechanical agitation and mixing, a comparative analysis was performed with different jet pressures, the development situation was visualized, and the performance of this method was evaluated. The results of MPS-CAE as one of the CAE systems showed that the cement slurry jet ratio in the planned improvement range, including the periphery of the mixing blade, by the middle-pressure jet grouting together with the mechanical agitation and mixing was increased and a high quality columnar soil-improved body was obtained. It is expected that the introduction of CAE will contribute to the visualization of the ground, and that CAE will be an effective tool for the visual management of construction for ground improvement and the maintenance of improved grounds during the life cycle of the ground-improvement method.

Abstract Background Tobacco products are considered significant, but preventable factors related to initiation and progression of periodontal diseases. We assessed the prevalence of periodontitis and evaluated its association with tobacco use and other factors amongst the adult population of Sunsari district in eastern Nepal. Methods A community-based, cross-sectional study was conducted in rural municipalities in the province one of eastern Nepal. A total of 440 adults were interviewed with a set of a pre-tested semi-structured questionnaire. Data on social demographics, adverse oral habits followed by periodontal clinical examination were recorded. Prevalence of periodontitis was assessed by a case definition provided by CDC-AAP. Univariate and multivariate logistic regression analysis was done to measure the association between tobacco use and other factors with periodontitis. Results The overall prevalence of periodontitis was found to be 71.6%. Majority (85.4%) of tobacco users had periodontitis and they were significantly associated with the disease and its severity. The study identified age groups, 45–65 years (AOR = 7.58, 95% CI 3.93–14.61), plaque accumulation (AOR = 1.01, 95% CI 1.00–1.02), smoking (AOR = 3.14, 95% CI 1.36–7.27), khaini users (smokeless tobacco, AOR = 2.27, 95% CI 1.12–4.61) and teeth loss (AOR = 2.02, 95% CI 1.21–3.38) as the significant factors associated with periodontitis. Conclusion The prevalence of periodontitis is high in the surveyed rural adult population. Cigarette smoking along with the use of smokeless tobacco in the form of khaini were identified as significant factors associated with periodontitis.

ObjectiveIn the past few decades, there has been an increase in high-quality studies providing evidence on the effectiveness of commonly performed procedures in paediatric otolaryngology. We believe that now is the time to re-evaluate the care process. We aimed to analyse (1) the regional variation in incidence and referrals of adenoidectomies, tonsillectomies and ventilation tube insertions in children in the Netherlands between 2016 and 2019, (2) whether regional surgical rates, referral rates and in-hospital surgical rates were associated with one another, and (3) the hospital variation in healthcare costs, which indicates the utilisation of resources.DesignRepeated cross-sectional analysis.SettingFour neighbouring Dutch provinces comprising 2.8 million inhabitants and 14 hospitals.ParticipantsChildren aged 0–15 years.Outcome measuresWe analysed variation in regional surgical rates and referral rates per 1000 inhabitants and in-hospital surgical rates per 1000 clinic visitors, adjusted for age and socioeconomic status. Furthermore, the relationships between referral rates, regional surgical rates and in-hospital surgical rates were estimated. Lastly, variation in resource utilisation between hospitals was estimated.ResultsAdenoidectomy rates differed sixfold between regions. Twofold differences were observed for adenotonsillectomy rates, ventilation tube insertion rates and referral rates. Referral rates were negatively associated with in-hospital surgical rates for adenotonsillectomies, but not for adenoidectomies and ventilation tube insertions. In-hospital surgical rates were positively associated with regional rates for adenoidectomies and adenotonsillectomies. Significant variation between hospitals was observed in costs for all resources.ConclusionsWe observed low variation in tonsillectomies and ventilation tube insertion and high variation in adenoidectomies. Indications for a tonsillectomy and ventilation tube insertion are well defined in Dutch guidelines, whereas this is not the case for an adenoidectomy. Lack of agreement on indications can be expected and high-quality effectiveness research is required to improve evidence-based guidelines on this topic.

Relevance. Before starting the therapeutic treatment of various periodontal diseases, it should be clearly understood that a high-quality treatment is possible only with complex therapy, excluding local irritating adverse factors in the oral cavity, elimination of inflammatory processes in the periodontal tissues, as well as violations of its function. One of the main tasks of the treatment of periodontal diseases is the preservation of the dentition with a single functional system.Purpose – to assess the use of the drug Kollapan in tooth extraction and treatment of periodontitis.Materials and methods. The clinical observation group consisted of 40 patients aged 19 to 65 years. The gender ratio was 3 : 2 (60% men, 40% women). The largest percentage of patients (65%) came to the clinic with complex tooth extraction. The remaining 35% – with generalized periodontitis of moderate and mild severity.Results. Clinical observation showed that in the first group of patients, whose therapy included the use of Collapan, after a complex tooth extraction, physiological healing of the hole was observed, the disappearance of inflammation within 24–36 hours after the surgery
