The digit ratio (2D:4D) has been associated with prenatal hormonal influences and various traits and pathologies. This article explores the relationship between 2D:4D and a series of common polymorphisms and Torque Teno Viruses. In this study, 120 healthy participants were included. The IGF2 Apa I, ACE I/D, INS -23 Hph I, VDR Fok I, VDR Apa I, VDR Taq I, AT1R A1166C polymorphism were genotyped by PCR-RFLP technique, and the IL-6 -174 G/C polymorphism by tetra-primer ARMS-PCR. The presence of TTV was identified by a hemi-nested PCR technique. Haplotype analyses were performed using the SHEsis software. The average 2D:4D values were similar for men and women. Overweight men presented higher 2D4D ratios than normal-weight women (p<0.05). Lower 2D:4D values were recorded in women with pregnancy loss or one child or none (p<0.001). Men with lower 2D4D ratios reported a higher number of children (p<0.001). The IGF2 GG and ACE DD were associated with a higher digit ratio in all subjects and in the women’s subset. A significant association was found in men between 2D:4D and the INS-23 Hph I – IGF2 Apa I T-G haplotype (p<0.01). The data obtained in this study indicate a sexual dimorphism for the digit ratio. The associations between 2D:4D and the genetic polymorphisms studied could be influenced by gender.
Colorectal cancer is the third most common cancer worldwide and represents a significant major public health issue. Therefore, the interest in detecting the multiple factors implied in the development of cancer has increased recently. One of the factors could be the Helicobacter pylori infection, but a direct causal connection is missing. This gram-negative bacterium infects approximately 4 billion individuals globally and various conditions such as gastroduodenal ulcers or gastric adenocarcinomas can be induced by it. Some of the reported carcinogenic effects of Helicobacter pylori bacterium are hypergastrinemia, chronic inflammation, dysbiosis, and toxin production. Each of these elements involved in the pathogenesis has various mechanisms of action. Dysbiosis can occur due to various treatments for the eradication of the Helicobacter pylori infection. This bacterium also has a proinflammatory effect at the gastric level which can predispose to the development of dysplasia or even neoplasia. The toxins produced by this bacterium, such as the vacuolating cytotoxin A, promote inflammation. In this review, we discuss the possible connections between the Helicobacter pylori infection, through its diverse pathogenic mechanisms, and colorectal neoplasm. Prospective studies are necessary to determine whether there certainly is a direct link between the two conditions.
The cytogenetic aberrations induced by doxorubicin (DOX) may be influenced by diet. Investigation regarding effects of low doses of DOX on chromosomal aberrations frequency in mice bone marrow. The study explored a possible relationship between diet, follow-up period, and cytostatic doses. Four mice groups received normal or high-fat (pork) diet. At the beginning of the 8th day mice from each group received a single intraperitoneal injection with DOX (dose range: 1.7-7.7 mg/kg b.w.) or isotonic saline solution (0.02 mL/g control mice). In the 10th (groups I, II) and 14th (groups III, IV) days from the beginning of the experiment, the mice were euthanized and chromosome aberrations were tested in bone marrow cells. The body weight of all mice who received DOX decreases, especially at higher doses. In the first three days post-injection, weight loss percentage was significantly influenced by DOX doses and/or type of diet (p0.05). DOX doses were able to increase the frequency of chromosomal aberrations. DOX acts as a potent inductor of cytogenetic aberrations in bone marrow cells, regardless of the type of diet.
Background: The highlighting of possible risk factors for urinary colonization in patients with obstructive urolithiasis that needed double J catheters implanted to preserve renal function. Methods: We performed a descriptive, retrospective study, carried out in the Urology Department of the Bucharest Central Military Hospital, between January 2020 and January 2022 and included 168 patients with urolithiasis who required the insertion of double J catheters. We studied the bacteriological profile, using both urine and JJ catheter samples. Results: We obtained a double J catheter colonization rate of 32% (54 patients) and 29% of urinary colonization (49 patients). The rate of urinary colonization is higher in patients with colonized ureteral catheters regardless of sex, age, and associated comorbidities. At the same time, we noticed an increased rate of urinary colonization in patients associated with diabetes, hypertension, and chronic kidney disease. Conclusions: The prevalence of urinary colonization in patients with double J catheters was 29%. The colonization of the JJ catheters, as well as the association with chronic diseases, such as diabetes, hypertension, and CKD (Chronic Kidney Disease), show an increased risk of urinary colonization.
Different factors may be involved in the clinical heterogeneity of spinal muscular atrophy disease. The vitamin D receptor (VDR) might be a candidate gene for this disease. Our study aimed to assess the preferential transmission of VDR polymorphisms from parents to SMA children. We genotyped 261 subjects (87 SMA nuclear families) for VDR FokI, BsmI, ApaI, and TaqI polymorphisms. The transmission of the genetic marker was estimated with Plink and FBAT software. It detected a preferential transmission of the rs731236 and rs7975232 variants to SMA1 patients and of rs1544410 variants to SMA2 patients. The variants of rs2228570 were preferentially transmitted to parents of all SMA patients. Haplotype analysis identified that haplotypes C-C-G-A and T-A-A-G seem to be involved in the booth type of SMA whereas the impact of T-A-A-A seems to be limited only to SMA2. Strong linkage disequilibrium (LD) between rs7975232 and rs1544410 was detected in samples from parents. Even though we investigated a small number of nuclear families the results suggest a potential link between VDR polymorphisms and SMA disease.
Stroke has a significant prevalence in Romania. The predisposition for this multifactorial disease is partially known. The aim of this study is to investigate the predisposition for stroke in Romanian population. Material and methods. We selected cases with recent ischemic stroke (n=100) and healthy control subjects (n=100). The AGTR1 A1166C (rs5186) polymorphism was genotyped by restriction of amplicons with Dde I endonuclease. Results. Active cigarette smoking (O.R. =6.92, p=0.0001) or presence of the AT1R C variant (O.R. =6.69, p=0.0006) in overweight or obese women significantly increase the risk for ischemic stroke. The diagnosis of stroke (71.5 vs 68 years old) or T2DM (63.39 vs 60.77 years old) was recorded at an older age in women compared to men (p<0.05). Obesity considered independent (O.R. =4.22, p<0.05) or in association with T2DM (O.R. = 10.16, p=0.0002) confers the highest risk of stroke when compared to women. Conclusions. Obesity in association with T2DM confers the highest risk of stroke for men when compared to women. Active cigarette smoking or AT1R C variant significantly increase the risk for stroke in women with a high BMI compared with controls.
Diabetes mellitus refers to metabolic disorders whose main characteristic is chronic hyperglycaemia. The cause is either disturbed insulin secretion, insulin resistance, or usually both. MicroRNAs represent a subclass of non-coding RNA molecules that are short in length, about 17-26 nucleotides. Since they are circulant and can be tissue-specific, their use as diagnostic biomarkers or screening for different diseases is currently undergoing deeper studies. It was found that 22 miRNAs were associated with the pathophysiology of T1DM, 34 with T2DM, and 16 miRNAs were identified to be common amongst T1DM and T2DM. All of them were reconfirmed in at least two separate studies.
In an attempt to standardize the X-ray analysis and to create relevant correlations between it and the functional results, we present a pilot model of an artificial neural network based on a Bayesian belief network (BNN) designed for the automatic analysis of anteroposterior X-ray of the knee following total knee arthroplasty and more precisely the analysis of the tibial component. A prospective analysis was conducted in which 30 patients were analyzed and two groups resulted: the first was made up of 12 cases considered “normal” by the examiners (optimal positioning and cementation) and the second one, which was considered “pathological” (incorrect positioning or cementation) and included 16 cases. Based on 22 points established on the tibial component several geometric sizes (calculated parameters) were computed. Several parameters were compared and the results were up to 75% accuracy, 81.25% sensitivity, and 66.7% specificity. BBNs can be a solution for X-ray evaluation of total knee arthroplasty and can improve the understanding of its evolution. It needs confirmation in time, its accuracy rising with the number of patients introduced in the analysis algorithm.
