Background: Researches on the association of dairy products consumption with Oligo-astheno-teratozoospermia (OAT) risk has been limited and controversial. Therefore, we aim to explore the aforementioned association among Chinese men.Methods: A hospital-based case-control study was conducted in men consisting of 106 cases of OAT and 581 controls. Intakes of dairy products and their related nutrients were collected using a semi-quantitative food frequency questionnaire and semen quality was analyzed according to the World Health Organization guidelines. The daily intake of dairy products and their related nutrients was categorized into three groups with the lowest tertile serving as the reference category. Odds ratios (ORs) and 95% confidence intervals (CIs) of association between dairy intake and OTA risk were calculated by the multivariable logistic regression models.Results: No significant association was found between total dairy (OR T3vs.T1 =1.53, 95% CI: 0.85–2.78), protein (OR T3vs.T1 =1.51, 95% CI: 0.84–2.75), or calcium (OR T3vs.T1 = 1.46, 95% CI: 0.81–2.66) and the OAT risk in the main findings. However, we observed a statistically significant positive association of dairy fat intake with OAT risk (OR T3vs.T1 =1.93, 95% CI: 1.06–3.58). The findings were consistent with the main results when we carried out subgroup analysis stratified by body mass index.Conclusion: A significant positive association was found between dairy fat intake and the risk of OAT. Further large-scale prospective studies are required to confirm this finding.

Background: Evidence of an association between dairy product and main related dairy nutrient intake, and the asthenozoospermia risk have been limited and controversial.Methods: A hospital-based case-control study including 549 men with asthenozoospermia and 581 normozoospermic controls was carried out in the infertility clinics of Shengjing Hospital of China Medical University between June, 2020 and December, 2020. Dietary intake was assessed with a validated food frequency questionnaire. According to the World Health Organization guidelines, semen parameters were collected through masturbation and were measured with WLJY9000 instrument and flow cytometry. The daily intake of dairy products and related nutrients was categorized into three groups according to control distribution, and the lowest tertile was used as the reference category. An unconditional multiple logistic regression was used to estimate the odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) for asthenozoospermia risk.Results: After adjustment for potential confounders, we found no statistically significant associations between the intake of total dairy products and asthenozoospermia risk (ORT3vs.T1 = 1.19, 95%CI = 0.85–1.67). Additionally, we generated null findings regarding the main related nutrients from dairy, including protein (ORT3vs.T1 = 1.19, 95%CI = 0.85–1.68), fat (ORT3vs.T1 = 1.28, 95%CI = 0.91–1.80), calcium (ORT3vs.T1 = 1.20, 95%CI = 0.85–1.68), saturated fatty acids (ORT3vs.T1 = 1.30, 95%CI = 0.92–1.83), and phosphorous (ORT3vs.T1 = 1.18, 95%CI = 0.84–1.67), and the asthenozoospermia risk. Of note, after stratification by body mass index (BMI), and the saturated fatty acids consumption from dairy was significantly associated with a higher asthenozoospermia risk (ORT3vs.T1 = 1.76, 95%CI = 1.01–3.09) among participants with a BMI below 25 kg/m2.Conclusion: This study provided limited evidence of an association between the intake of total dairy products and the main related dairy nutrients including protein, fat, calcium, saturated fatty acids, and phosphorus, and the asthenozoospermia risk. Further studies are warranted to confirm our findings in the future.

A case-control study investigated the association between dietary fat and breast cancer in Saudi Arabian women attending a specialist hospital in Riyadh. Women with breast carcinoma [n= 499] newly diagnosed between 1996-2002, and control women [n = 498] randomly selected from patients’ attendants and relatives, completed a food frequency questionnaire. Serum levels of triglycerides and total cholesterol were measured. A significant positive association was found between risk of breast cancer and intake of fats, protein and calories. Adjusted odds ratios for the highest quartile of intake versus the lowest were 2.43 for saturated fat, 2.25 for animal protein, 2.12 for polyunsaturated fat, 1.88 for cholesterol and 2.69 for total energy from dietary intake. For serum triglycerides the adjusted odds ratio was 2.16 for the highest quartile

Abstract Background No report is available about diet-disease associations in the understudied region of Afghanistan. Although inflammatory potential of diet has been linked with several cancers, information about gastric cancer is scarce. This study aimed to investigate the relationship between dietary inflammatory index (DII) and odds of gastric cancer in Afghanistan. Methods In this hospital-based case-control study, we enrolled 90 newly-diagnosed cases of gastric cancer and 180 age (± 5) and sex-matched controls. All cases were pathologically confirmed gastric cancer patients, with no history of any type of other pathologically confirmed cancers. Controls were healthy individuals and relatives of patients in the hospital. Dietary assessment was done by a pre-tested food frequency questionnaire. DII was calculated based on energy-adjusted amounts of several foods and nutrients with inflammatory or anti-inflammatory potential, as introduced by earlier studies. Results Mean age of study participants was 54 years, of them 73% were males. After adjustment for age and sex, individuals in the highest tertile of DII were 2.47 times (95% CI: 1.31–4.66) more likely to have gastric cancer compared with those in the lowest tertile. Further adjustment for other potential confounders did not substantially affect the association; such that participants with the greatest DII had approximately 3.59 times (95% CI: 1.16, 11.02) increased odds of gastric cancer than those with the lowest adherence. Additional adjustment for BMI strengthened the association (OR: 3.75; 95% CI: 1.14–12.30). Conclusion We found a significant positive association between inflammatory potential of diet and risk of gastric cancer. Further studies with prospective nature are required to confirm this association.

Citrullinated proteins have been suggested to play a critical role in the pathogenesis of multiple sclerosis (MS). Anticyclic citrullinated peptide (anti-CCP) antibody is used in the early diagnosis of rheumatoid arthritis (RA). The objective of this study was to investigate the presence of anti-CCP antibody in patients with MS compared to RA patients and healthy controls. Fifty patients with MS (38 females, 12 males; mean age 36.72 ± 8.82 years), 52 patients with RA (40 females, 12 males; mean age 40.87 ± 10.17 years), and 50 healthy controls (32 females, 18 males; mean age 38.22 ± 11.59 years) were included in this study. The levels of serum anti-CCP antibody were measured using an enzyme-linked immunosorbent assay (ELISA). The results of the study showed that anti-CCP antibody levels were significantly higher in RA patients versus MS or healthy controls(P<0.001). Moreover, anti-CCP antibody was positive in 43 (83%) patients with RA, while it was negative in all MS patients as well as in all healthy controls. Also, no significant correlation was found between the anti-CCP levels and EDSS scores(r=-0.250). In conclusion, the results of this study did not support a positive association between serum anti-CCP antibody and MS.

Abstract Background Globally over 2.6 million pregnancy ends with stillbirth annually. Despite this fact, only a few sherds of evidence were available about factors associated with stillbirth in Ethiopia. Therefore, the study aimed to spot factors related to stillbirth among women who gave birth at Hawassa University Comprehensive Specialized Hospital Hawassa, Sidama Ethiopia, 2019. Methods Facility-based unmatched case-control study was conducted at Hawassa University Comprehensive Specialized Hospital. Cases were selected using simple random sampling technique and controls were recruited to the study consecutively after every case selection with case to control ratio of 1 to 3. Data were coded and entered into Epi-data version 3.1 and exported to SPSS version 24 for analysis. Results A total of 106 cases and 318 controls were included in the study. Number of antenatal care visit [AOR = 0.38, 95% CI (0.15, 0.95)], lack of partograph utilization [AOR = 4.1 95% CI (2.04, 10.5)], prolonged labor [AOR = 6.5, 95% CI (2.9, 14.4)], obstructed labor [AOR = 3.5, 95% CI (1.5, 9.4)], and congenital defect [AOR = 9.7, 95% CI (4.08, 23.0)] were significantly associated with stillbirth. Conclusion Absence of partograph utilization, prolonged labor, obstructed labor, antepartum hemorrhage and congenital anomaly were found to have positive association with stillbirth.

Objective To evaluate whether the presence of maternal blood pressure reduces the risks of morbidity, perinatal mortality and morbidity at 24 months of age in very low birth weight infants (VLBWIs) compared with a control group. Methods A retrospective, observational, case-control study. Total 49 VLBWIs were allocated to the study group, called the maternal arterial hypertension group (AHG), and matched with 44 in the control group (CG). The infants were assessed during hospitalization and at 12 and 24 months corrected age at a specialized clinic. For the assessment of growth, the World Health Organization (WHO) Anthro software (Geneva, 2006) was used, and for the psychomotor assessment, the Denver II test was used. Results In relation to the antenatal variables, the infants of the AHG had more centralized circulation assessed by Doppler, received more corticosteroids and magnesium sulfate, and were born by cesarean section more frequently. In terms of the postnatal and in-hospital outcomes, the AHG had a higher gestational age at birth (30.7 versus 29.6 weeks) and a lower frequency of 5-minute Apgar scores of less than 7 (26.5% versus 52.3%). The CG had a higher rate of pulmonary dysplasia (30.2% versus 8.3%). There were no differences in terms of hospital mortality, complications, somatic growth and functional problems at 24 months of corrected age. Conclusion The presence of maternal hypertension, especially preeclampsia, was not a protective factor against morbidity, mortality and evolution in VLBWIs aged up to 24 months. Therefore, the clinical practice should be focused on prolonging the pregnancy for as long as possible in these conditions as well.
