The effort of leptospirosis prevention in Sleman currently only limited to counseling and treatment of the patient, while the patient search, ways of transmission of leptospirosis from rats to humans, have never implemented in an integrated manner. The study aimed to investigated the relationship between the environmental residential condition with the risk of leptospirosis in Sleman Regency. The research used a survey method  with case control study design. The results showed that environmental factors, which are not proved to have a relationship with the risk of leptospirosis were residential condition ({p=0,108} OR=3,818 {95%CI:0,922–15,811}), the trash bin condition ({p=1,000} OR=1,138 {95%CI:0,420–3,081}) and the sewer condition ({p=0,415} OR=0,551 {95%CI:0,187–1,624}). Environmental factors that associated with the risk of leptospirosis was the presence of rats ({p=0,001} OR=13,594 {95%CI:2,754–67,107}). The effort should be made in order to prevent the increasement of Leptospirosis cases by sanitation improvement and avoiding direct contact with rats as well as it litter. The Government should be pay more attention in the vector control programs, especially in leptospirosis prone areas so the prevention effort to be able run effectively and efficiently.

The aim of the present study was to investigate the influence of HLA-DRB1 alleles on the genetic susceptibility to multiple sclerosis in the Lithuanian population. Material and Methods. A total of 120 patients with multiple sclerosis and 120 unrelated healthy controls were enrolled in this case-control study. Allelic frequencies were compared between the groups. HLA-DRB1 alleles were genotyped using the polymerase chain reaction. Results. HLA-DRB1*15 was present in 55.8% of the patients with multiple sclerosis and 10.0% of the controls (OR, 5.58; 95% CI, 3.19–9.77; P<0.0001). The protective alleles that were found to be more prevalent among the controls compared with the patients with multiple sclerosis were HLADRB1* 01 (26.7% vs. 7.5%, P<0.0001), *03 (17.5% vs. 8.3%, P=0.034), and *16 (11.7% vs. 3.3%, P=0.014). HLA-DRB1*15 was more common among the female patients with multiple sclerosis than among the male patients (68.4% vs. 34.1%; OR, 4.18; 95%, CI 1.90–9.22; P=0.001). The heterozygous inheritance of HLA-DRB1*15 allele was more common in the patients with a history of maternal multiple sclerosis than in those with a history of paternal multiple sclerosis (29.4% vs. 9.8%; P=0.045). Conclusions. HLA-DRB1*15 was found to be associated with multiple sclerosis in the Lithuanian population. This allele was more prevalent among the female patients with multiple sclerosis. Maternal multiple sclerosis was more common than paternal multiple sclerosis, but the relationship with HLA-DRB1*15 allele was not established. HLA-DRB1*01, *03, and *16 appeared to be the protective alleles in this series.

Introduction: It has been proposed that dietary intake is associated with multiple sclerosis (MS). The present case-control study was conducted to investigate the relationship between intake of different food groups and occurrence of MS among the recently diagnosed adult patients in Yazd City, Iran. Materials and Methods: In the current study, a group of 45 patients who have recently been diagnosed with MS and 100 healthy controls were investigated in this research. Participants were matched regarding their gender. Dietary intakes were assessed using a self-administered semi-quantitative food frequency questionnaire (FFQ). Participants also completed a demographic questionnaire including information such as age, gender, marital status, job, education, sun exposure, smoking, sunscreen, body mass index (BMI), economic status, as well as their spouses' occupations and education. Logistic regressions in crude and multivariable-adjusted models were used to investigate the relationship between food groups and the odds of developing MS. Results:  The findings showed that participants with high consumption of fruits, potatoes, refined grains, pickles, and fibers had a significantly lower chance for developing MS after adjustment for the maximum possible confounding variables (P < 0.05). Conclusion: The present study revealed that several food groups or nutrients are associated with the development of MS.  Further multi-central prospective studies including more participants are needed to confirm these results

Abstract Background: PGF and TNFAIP2 are important angiogenic factors, which were abnormal expression in cervical cancer (CC). However, there is currently no report investigating the relationship of PGF and TNFAIP2 gene polymorphisms to CC risk.Methods: We conducted a case-control study of 342 CC patients and 498 cancer-free controls in a Chinese Uygur female population. Three SNPs (PGF rs8019391, PGF rs2268615, and TNFAIP2 rs710100) were selected and genotyped to assess the possible association of PGF and TNFAIP2 polymorphisms with CC susceptibility. Logistic regression analysis adjusted by age was used.Results: PGF rs2268615 (OR = 1.39, 95% CI = 1.04-1.86, p = 0.024) and TNFAIP2 rs710100 (OR = 1.44, 95% CI =1.07-1.95, p = 0.018) polymorphisms were associated with the increased risk of CC. Moreover, T allele of PGF rs8019391 was highly represented in patients with stage III–IV compared with stage I-II (OR = 2.17, p = 4.58´10-4). MDR analysis revealed a positive interaction between the SNPs.Conclusion: Our data indicated that PGF rs2268615, and TNFAIP2 rs710100 polymorphisms might be risk factors for CC susceptibility, which contributed to the increased risk of CC.Trail registration: Not applicable.

Objectives: There is evidence the slope of the tibial plateau may play a role in need for revision following ACL reconstruction (ACLR), however, previous studies are limited by small sample sizes, radiographic measurement, single surgeon experience, lateral tibial posterior slope (LTPS) only, or a lack of confounder adjustment. Further, the role of the medial posterior tibial slope (MTPS) on revision risk has yet to be evaluated. We sought to (1) determine the relationship of revision status following ACLR and LTPS, (2) determine the relationship of revision status and MTPS, and (3) determine the relationship of revision status and the difference between MTPS and LTPS. Methods: We conducted a nested case-control study of 317 matched pairs using an integrated U.S. healthcare system’s ACLR registry (2006- 2014). Cases were defined as patients who underwent a revision following primary unilateral ACLR; controls were defined from the same cohort as non-revised patients during the same time frame. Controls were matched to cases according to age, gender, body mass index, race, graft type, femoral fixation device, and follow-up time. Magnetic resonance imaging (MRI) images were used by a single blinded reviewer to measure tibial slopes. Wilcoxon signed rank test was applied to compare the slopes between revised and non-revised groups continuously and McNemar test to compare slopes of ≥12° between groups. Results: No difference was observed between revised and non-revised patients in LTPS (mean: 6.1 vs. 6.1, p=0.972) or MTPS (mean: 4.6 vs. 4.9, p=0.281) measurement. When comparing revised ACLR to non-revised ACLR, a greater proportion of revised ACLR had a LTPS of ≥12° (7.6% vs. 3.8%, P=0.034), while no difference was found in the proportion of ACLR with a MTPS ≥12° (1.6% vs. 2.5%, P=0.405). No difference was found when evaluating the medial-to-lateral slope difference (-1.5 vs. -1.2, p=0.289). Conclusion: In our nested case-control study of over 300 revised ACLR patients matched to non-revised patients, we did not find an association between the slope of the lateral and medial tibial plateaus and revision.
