Nutritional exposure is considered the main environmental influence that contributes to gallstone disease (GD).
The aim of this study was to determine food intakes patters and estimate risk of GD.
A nested case-control study was carried out within the framework of a previous screening study conducted on a representative sample in Rosario, Argentina. Participants underwent a personal interview. Average amount of each food intake and quantity nutrients were estimated applying a food-frequency questionnaire. Food consumption patterns were identified by principal component analysis, and logistic regression analysis was used to estimate risks.
The sample was conformed by 51 cases and 69 controls. Two dietary patterns were identified. Cases were characterised by the unhealthy intake pattern (high intakes of animal fats, sugar, cereals, grains, cold cuts, processed meats, chicken with skin, fat beef and low intake of red vegetables and yellows, cabbages, fruits and fish).
Controls were characterised by the healthy intake pattern (high intake of skinless chicken, nuts, lean beef, vitamin A and C rich fruits, and low consumption of chicken with skin, green leaves vegetables and sprouts). The unhealthy pattern showed an increased risk of developing GD while healthy patter behaved as a protective factor.
La exposición nutricional se considera la principal exposición ambiental que contribuye a la formación de cálculos biliares.
El objetivo de este trabajo fue determinar el patrón de consumo alimentario de casos y controles de EC y estimar el riesgo de desarrollar la enfermedad según los distintos patrones constituidos.
Se llevó a cabo un estudio analítico retrospectivo transversal de casos y controles, anidado a un estudio de prevalencia realizado en Rosario. Todos los participantes fueron entrevistados personalmente. El consumo de alimentos se consignó a través de un cuestionario semi-cuantitativo de frecuencia de consumo. Para determinar patrones de consumo alimentario se realizó un análisis de componentes principales, y análisis de regresión logística múltiple para evaluar riesgos.
La muestra quedó conformada por 51 casos y 69 controles. Se determinaron dos componentes que permitían diferenciar los casos de los controles, a través de las cuales se establecieron 2 patrones de consumo. Los casos se caracterizaron por un consumo determinado por el Patrón Poco saludable (altas ingestas de grasas animales, azúcar, cereales, granos, fiambres y embutidos) y los controles por el consumo del patrón Saludable (altas ingestas de pollo sin piel, frutas secas, carne vacuna magra, frutas, lácteos enteros). El patrón Poco saludable, aumentó el riesgo de desarrollar EC mientras que el patrón Saludable, se comportó como protector.
Los patrones constituidos diferencian los casos de los controles, y la ingesta propia de los casos se correlaciona con un perfil de consumo que caracteriza a las culturas occidentales modernas y urbanas.

UNASSIGNED: Neural tube defects (NTDs) occur as a result of incomplete closure of the neural tube by the embryonic age of 26 to 28 days. Addressing factors associated with NTDs would help to identify and prioritize high-risk women, which in turn guides the preventive strategy. The study aimed to identify factors associated with NTDs among women who gave birth or had a second-trimester abortion at Adama Hospital Medical College, from January 1st to December 31st, 2019.
UNASSIGNED: Hospital based unmatched case-control study was conducted on 344 women. Data were analyzed with SPSS 20. Descriptive statistics were computed. Binary logistic regression analysis was performed to determine factors associations with NTDs.
UNASSIGNED: The odds of having a fetus with NTDs were 2.19 times higher among women who are not in a marital relationship (AOR = 2.19; 95% CI: 1.13, 4.25). Women with a previous history of Abortion or stillbirth had 3 fold increased risk of having a fetus with NTDs (AOR = 3.05; 95% CI: 1.58, 5.88). Inadequate housing condition nearly doubles the odds of having a fetus with NTDs (AOR = 1.91; 95% CI: 1.20, 3.04). Folic acid or multivitamin supplementation early in pregnancy reduced the odds of having a fetus with NTDs by 43% (AOR = 0.57; 95% CI: 0.35, 0.91).
UNASSIGNED: Being not in a marital relationship, previous history of abortion or stillbirth, and living in inadequate housing conditions were risk factors for NTDs, while multivitamins or folic acid supplementation was a protective factor.

Abdominal pain has been rarely reported in individuals infected with Toxoplasma gondii (T. gondii). The aim of this study was to determine the association between T. gondii infection and abdominal pain. Two hundred and ninety-nine patients with abdominal pain (cases) and 299 age- and gender-matched people without abdominal pain (controls) were tested for anti-T. gondii IgG and IgM antibodies. Twenty-four (8.0%) of the 299 cases and 12 (4.0%) of the 299 controls were positive for anti-T. gondii IgG antibodies (OR: 2.08; 95% CI: 1.02-4.25; P = 0.03). The seroprevalence of T. gondii infection was significantly higher in women with frequent abdominal pain than in women without this clinical feature (OR: 2.30; 95% CI: 1.06-4.96; P = 0.02). Twelve (4.0%) of the 299 cases and 7 (2.3%) of the 299 controls had high (>150 IU mL-1) anti-T. gondii IgG antibody levels (OR: 1.74; 95% CI: 0.67-4.49; P = 0.24). Seven (29.2%) of the 24 cases with anti-T. gondii IgG antibodies and 3 (25.0%) of the 12 controls with anti-T. gondii IgG antibodies were positive to anti-T. gondii IgM antibodies (OR: 1.23; 95% CI: 0.25-5.97; P = 1.00). Results suggest an association between T. gondii infection and frequent abdominal pain. Further research to confirm this association should be conducted.

BACKGROUND: Autism spectrum disorder (ASD) is heritable neurodevelopmental disorders (NDDs), but environmental risk factors have also been suggested to a play a role in its development. Prenatal, perinatal and parental factors have been associated with an increased risk of ASD in children. The aim of the present study was to explore the prenatal, perinatal, and parenting risk factors in children with autism spectrum disorder (ASD) from Beijing, China by comparing them with typically developing (TD) children.
METHODS: A sample of 151 ASD children\'s parents who from rehabilitation institutions in Beijing were enrolled in this study, and an additional 151 children from kindergartens in Beijing were recruited as a control group (child age: mean = 4.4 years). TD children were matched according to age, sex and maternal education. We explored the maternal AQ (Autism Spectrum Quotient) scores (mean:19.40-19.71, no significant difference between two groups) to referring the genetic baseline. This study evaluated 17 factors with unadjusted and adjusted analyses.
RESULTS: Birth asphyxia was associated with a more than a thirteen-fold higher risk of ASD (adjusted odds ratio (AOR) = 13.42). Breastfeeding difficulties were associated with a higher risk of ASD(AOR = 3.46). Parenting influenced the risk of ASD, with low responding (LR) and harsh or neglectful parenting associated with a higher risk of ASD in offspring (AOR = 2.37 for LR, AOR = 3.42 for harsh parenting and AOR = 3.01 for neglectful parenting). Maternal fever during pregnancy was associated with a higher risk of ASD in offspring (AOR = 3.81).
CONCLUSIONS: Many factors were associated with ASD in offspring. Further assessment is needed to elucidate the role of modifiable environmental factors to inform prevention strategies.

UNASSIGNED: Cervical cancer is the leading cause of cancer mortality among women in Kenya. Two thirds of cervical cancer cases in Kenya are diagnosed in advanced stages. We aimed to identify factors associated with late diagnosis of cervical cancer, to guide policy interventions.
UNASSIGNED: An unmatched case control study (ratio 1:2) was conducted among women aged ≥ 18 years with cervical cancer at Kenyatta National and Moi Teaching and Referral Hospitals. We defined a case as patients with International Federation of Gynecology and Obstetrics (FIGO) stage ≥ 2A and controls as those with stage ≤ 1B. A structured questionnaire was used to document exposure variables. We calculated adjusted odds ratio (aOR) to identify any associations.
UNASSIGNED: We enrolled 192 participants (64 cases, 128 controls). Mean age 39.2 (±9.3) years, 145 (76 %) were married, 77 (40 %) had primary level education, 168 (88 %) had their first pregnancy ≤ 24 years of age, 85 (44 %) were > para 3 and 150 (78 %) used contraceptives. Late diagnosis of cervical cancer was associated with cost of travel to cancer centres > USD 6.1 (aOR 6.43 95% CI [1.30, 31.72]), age > 50 years (aOR 4.71; 95% CI [1.18, 18.80]), anxiety over cost of cancer care (aOR 5.6; 95% CI [1.05, 32.72]) and ultrasound examination during evaluation of symptoms (aOR 4.89; 95% CI [1.07-22.42]). Previous treatment for gynecological infections (aOR 0.10; 95% CI [0.02, 0.47]) was protective against late diagnosis.
UNASSIGNED: Cost of seeking care and the quality of the diagnostic process were important factors in this study. Decentralization of care, innovative health financing solutions and clear diagnostic and referral algorithms for women presenting with gynecological symptoms could reduce late-stage diagnosis in Kenya.

OBJECTIVE: Chinese physicians developed the Tibial Transverse Transport (TTT) technique to treat diabetic foot ulcers with more than 90% effective rate. But this method still could not avoid the in-hospital death of patients. This study adopted a case-control study to explore the risk factors of in-hospital death in elderly patients with chronic ischemic diabetic foot after receiving TTT treatment.
METHODS: A total of 54 patients were included in the study from January 1, 2017 to April 30, 2021, by being paired with the cases in case group with their demographic data and results of blood routine, liver and kidney function. There were nine patients in case group with six male and three male. Forty-five patients were selected in control group according to gender and diabetes type with 30 male and 15 female. Single factor logics regression analysis was used to explore the risk factors and odd ratios (OR) of in-hospital death in patients. The nomogram and decision curve analysis (DCA) had been done by R Studio software.
RESULTS: The study found that age, course of diabetic foot, small dense low-density Lipoprotein (smLDL), homocysteine (Hcy), superoxide dismutase (SOD), and prealbumin (PA) were risk factors for in-hospital death of patients. The smLDL had the highest risk. The nomogram showed that PA accounted for the largest proportion in the death risk factors. The results of DCA proved that above six risk factors were the risk factors for patients with TEXAS Stage 3 and 4 diabetic foot ulcers.
CONCLUSIONS: In the future diagnosis and TTT treatment for diabetic foot ulcers, doctors need to pay close attention to age, course of diabetic foot, smLDL, Hcy, SOD, and PA.

UNASSIGNED: A certain number of myasthenia gravis (MG) patients clinically had type 2 diabetes mellitus (T2DM) prior to MG onset, which suggests that the onset of MG may correlate with the history of T2DM. This study aimed to examine the correlation between MG and T2DM.
UNASSIGNED: In a single-center, retrospective, 1:5 matched case-control study, all 118 hospitalized patients with a diagnosis of MG from 8 August 2014 to 22 January 2019 were enrolled. In total, four datasets with different sources of the control group were retrieved from the electronic medical records (EMRs). Data were collected at the individual level. A conditional logistic regression analysis was used to test the risk of MG associated with T2DM.
UNASSIGNED: The risk of MG was significantly associated with T2DM, and there were notable differences by sex and age. Whether compared to the general population, general hospitalized patients without autoimmune diseases (AIDs), or patients with other AIDs except MG, women aged over 50 years with T2DM had an increased risk of MG. The mean onset age of diabetic MG patients was more than that of the non-diabetic MG patients.
UNASSIGNED: This study demonstrates that T2DM is strongly associated with the subsequent risk of MG and varies significantly by sex and age. It reveals that diabetic MG may be a unique subtype that is different from the conventional MG subgroup classification. More clinical and immunological features of diabetic MG patients need to be explored in further studies.

BACKGROUND: Investigation of risk factors for the presence of vancomycin-resistant enterococci (VRE) in inpatients on surgical wards and associated intensive care units of a German tertiary care hospital.
METHODS: A single-centre retrospective matched case-control study was performed with surgical inpatients admitted between July 2013 and December 2016. Patients with in-hospital detection of VRE later than 48 h after admission were included and comprised 116 VRE-positive cases and 116 VRE-negative matched controls. VRE isolates of cases were typed by multi-locus sequence typing.
RESULTS: ST117 was identified as the dominant VRE sequence type. Next to length of stay in hospital or on an intensive care unit and previous dialysis the case-control study revealed previous antibiotic therapy as a risk factor for the in-hospital detection of VRE. The antibiotics piperacillin/tazobactam, meropenem, and vancomycin were associated with the highest risks. After taking into account length of stay in hospital as possible confounder other potential contact-related risk factors such as previous sonography, radiology, central venous catheter, and endoscopy were not significant.
CONCLUSIONS: Previous dialysis and previous antibiotic therapy were identified as independent risk factors for the presence of VRE in surgical inpatients.

BACKGROUND: Various inflammatory diseases have been associated with the administration of various vaccines. Several reports have associated vaccine administration with the demyelinating diseases of the central nervous system (CNS). However, no clear or strong scientific evidence exists to support the association of vaccine administration with the onset of demyelinating diseases. Some CNS demyelination diseases such as acute disseminated encephalomyelitis (ADEM) and neuromyelitis optica spectrum disorders (NMOSD) were reported following the administration of COVID-19 vaccines. In this study, new onset multiple sclerosis (MS) following COVID-19 vaccine administration was reported.
METHODS: In this longitudinal observational case-control study, a total of 65 participants were studied, who were divided into two groups. Group A included 32 MS patients who were diagnosed post-COVID-19 vaccine administration and group B included 33 participants who received COVID-19 vaccines and did not develop MS. Group B was used as a control. The Chi-square test and logistic regression analysis were carried out using Statistical Product and Service Solutions (SPSS) (IBM SPSS Statistics for Windows, Armonk, NY) software.
RESULTS: Univariate and multivariate logistic regression analysis was performed and a significant correlation between the risk factors and the development of MS post-COVID-19 vaccination was identified.
CONCLUSIONS: The risk factors, identified in this study, can be used as significant independent predictors for developing MS post-COVID-19 vaccinations.

Biopsy-proven giant cell arteritis (GCA) occasionally presents without acute-phase reaction. In this setting, GCA may be initially overlooked and glucocorticoid treatment unduly delayed, potentially increasing ischemic risk.
From an inception cohort of patients with newly diagnosed, biopsy-verified GCA, we retrieved all cases without elevation of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level before starting glucocorticoid treatment. We compared the baseline features and outcomes of these patients and two additional patients recruited after GCA diagnosis with those of 42 randomly selected patients with high baseline ESR and CRP.
Of 396 patients, 14 (3.5%) had lower baseline values of both ESR and CRP. Lower baseline ESR and CRP were associated with fewer American College of Rheumatology criteria met (p < 0.001, 95% CI - 1.1; - 0.9), and less jaw claudication (p = 0.06, 95% CI 0.8; 44.9), but similar rates of permanent blindness (p = 1.0). Patients with lower ESR and CRP also showed obvious differences regarding mean blood cell counts and mean hemoglobin level, but also less anti-cardiolipin antibody positivity (p = 0.04, 95% CI 0.8; ∞) and hepatic cholestasis (p = 0.03, 95% CI 1.0; 422). Patients with lower ESR and CRP had fewer GCA relapses (p = 0.03, 95% CI - 1.1; - 0.1), fewer glucocorticoid-induced complications (p = 0.01, 95% CI - 2.0; - 0.1), and successfully stopped glucocorticoids sooner than the other patients (18.3 months vs 34 months in average, p = 0.02, 95% CI - 27;- 0.9).
Biopsy-proven GCA presenting with lower ESR and CRP is not an exceptional occurrence. It is clinically less typical but carries similar ischemic risk to other forms of the disease. Conversely, the late GCA prognosis of these patients is excellent.
