Tobacco contains several genotoxic agents including N-nitrosamine which has the potential to cause significant nuclear damage. Nuclear blebbing is a form of protrusion on the nuclear membrane and could potentially be caused by tobacco-induced genotoxicity and is closely associated with malignancy. Thus, the present study aimed to assess if tobacco-associated oral potentially malignant disorders including oral submucous fibrosis (OSF) and oral leukoplakia have a higher nuclear blebbing frequency than patients with normal oral mucosa with no history of tobacco use.

The sample consisted of patients with OSF (n = 30) and oral leukoplakia (n = 10) and normal oral mucosa (n = 10). Exfoliated cells collected from the study groups were smeared on a clean microscopic slide and stained by May-Grunwald-Giemsa stain. A baseline frequency of nuclear blebbing was evaluated using a bright-field microscope with a ×100 objective. The number of nuclear blebbing per 1,000 epithelial cells was recorded and expressed in percegnificantly higher in oral potentially malignant disorders than normal mucosa. Nuclear blebbing also exhibited a strong dose- and time-dependent correlation with tobacco usage and clinical staging in OSF. The nuclear blebbing frequency could be a noninvasive, economic tool to assess malignant risk in tobacco-induced oral potentially malignant disorders.

The recent studies have shown that sildenafil citrate can enhance estrogen-induced proliferation of the endometrium in infertile women.

This study was aimed to investigate whether sildenafil citrate could affect pregnancy outcomes in infertile women receiving frozen-thawed embryo transfer (FET) after resection of intrauterine adhesions (IUAs).

A total of 310 subjects who met the inclusion criteria were recruited and divided into the control group (group A) and the sildenafil citrate group (or the SC group, group B). The 2 groups were, respectively, divided into 2 subgroups based on the severity of reformed adhesions (1) group A1 (with mild IUAs) and group A2 (with moderate to severe IUAs) and (2) group B1 (with mild IUAs) and group B2 (with moderate to severe IUAs). Therapeutic effects of sildenafil citrate on the cases were evaluated after resection of IUAs during FET cycles. Endometrial thickness, endometrial pattern, and pregnancy outcomes were evaluated and compared between the 2 groups.

Cardiovascular disease (CVD) is a major cause of death in patients with chronic kidney disease (CKD) on dialysis. Mortality rates are still unacceptably high even though they have fallen in the past 2 decades. Hyperphosphatemia (elevated serum phosphate levels) is seen in almost all patients with advanced CKD and is by far the largest remaining modifiable contributor to CKD mortality.

Phosphate retention drives multiple physiological mechanisms linked to increased risk of CVD. Fibroblast growth factor 23 and parathyroid hormone (PTH) levels, both of which have been suggested to have direct pathogenic CV effects, increase in response to phosphate retention. Phosphate, calcium, and PTH levels are linked in a progressively worsening cycle. Maladaptive upregulation of phosphate absorption is also likely to occur further exacerbating hyperphosphatemia. Even higher phosphate levels within the normal range may be a risk factor for vascular calcification and, thus, CV morbidity and mortality.

Key Messages Despite current phosphate management strategies, most patients on dialysis are unable to consistently achieve target phosphate levels, indicating a need for therapeutic innovations [RealWorld dynamix. Dialysis US Spherix Global Insights, 2019]. Given a growing evidence base that the dominant mechanism of phosphate absorption is the intestinal paracellular pathway, new therapies are investigating ways to reduce phosphate levels by blocking absorption through the paracellular pathway.

In patients with atrial fibrillation (AF) at risk for stroke, dabigatran 150 mg twice a day (DE150) is superior to warfarin for stroke prevention. SR59230A However, there is paucity of data with respect to bleeding risk at this dose in elderly patients (≥75 years). We aimed to evaluate the safety of DE150 in comparison to warfarin in a real-world population with AF and low bleeding risk (HAS-BLED score ≤2).

In this prospective observational study, 754 consecutive patients with AF and HAS-BLED score ≤2 were included. We compared outcome of elderly patients (age ≥75 tears) to younger patients (age <75 years). The primary end point was the combined incidence of all-cause mortality, stroke, systemic emboli, and major bleeding event during a mean follow-up of 1 year.

There were 230 (30%) elderly patients, 151 patients were treated with warfarin, and 79 were treated with DE150. Fifty-two patients experienced the primary endpoint during the 1-year follow-up. Among the elderly, at 1-year of follow-up, the cumulative event rate of the combined endpoint in the DE150 and warfarin was 8.9 and 15.9% respectively (p = 0.14). After adjustment for age and gender, patients who were treated with DE150 had a nonsignificant difference in the risk for the combined end point as patients treated with warfarin both among the elderly and among the younger population (HR 0.58, 95% C.I = 0.25-1.39 and HR = 1.12, 95% C.I 0.62-2.00, respectively [p for age-group-by-treatment interaction = 0.83).

Our results suggest that Dabigatran 150 mg twice a day can be safely used among elderly AF patients with low bleeding risk.

Lipid disturbances are common in ESRD patients. In peritoneal dialysis (PD) patients, dyslipidemia is even more common. This study aimed to examine whether serum lipids were associated with prognosis of PD patients.

Patients from a multicenter retrospective cohort were used for the present study. The primary endpoint was all-cause mortality. Cox regression was used to analyze the association between serum lipids including total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein, and triglycerides and the prognosis.

The results showed that lower total cholesterol and LDL levels at the initiation of PD predicted higher all-cause mortality in PD patients. Multivariate analysis reveal that the association disappeared after adjusting for age, gender, albumin, prealbumin, protein catabolic rate normalized to body weight, C-reactive protein, and residual renal function. Further analysis showed that patients with lower total cholesterol/LDL had a higher mortality only during the first 24 months of follow-up.
