According to a recent study, a patient-centered approach in anemia management at renal palliative care (PC) has the potential to alleviate symptom burden and decrease the reliance on transfusions. This study's findings were published in the Journal of Pain and Symptom Management.

This retrospective study was carried out to evaluate the utilization of a patient-centered strategy in the treatment of anemia and symptom management. A total of 158 patients visited the renal PC clinic, with 47 patients being included in the data analysis.

The patients included in the analysis had a mean age of 81.3 (9.5) years and a glomerular filtration rate of 8.6 (5.3) mL/min/1.73 m². Among them, 68.1% were receiving erythropoiesis-stimulating agents (ESAs) and 44.7% were taking iron supplements. Only 4.3% of patients required transfusion over the past six months. The mean hemoglobin level was 9.8 (1.4) g/dL, with a mean POS-S renal score of 4.7 (3.2). A significant majority of patients (93.6%) reported a satisfactory rating for the "weakness and lack of energy" item.

Therefore, implementing a patient-centric approach in anemia management at renal primary care has the potential to alleviate the burden of symptoms and reduce the dependency on transfusions.

According to a recent study, sodium bicarbonate has comparable efficacy to classic unfractionated heparin in the prevention of catheter lumen thrombosis. Additionally, it serves as a cost-effective alternative that can be utilized in cases where heparin is not recommended. This study’s findings were published in the journal, International urology and nephrology.

In the prospective trial, 426 patients were assigned to four groups. : femoral bicarbonate (n = 100), femoral heparin (n = 113), jugular bicarbonate (n = 113), and jugular heparin (n = 113), Patients were allocated to receive either 8.4% sodium bicarbonate or heparin (5000 IU/ml) in a consecutive manner. Information on basic characteristics, catheters, dialysis sessions, and complications was collected.

The mean time to the last effective dialysis treatment for those on heparin was 10.7 ± 12.1 days compared to 11.5 ± 10.8 days for the bicarbonate group. Among the 25 (5.9%) patients who faced blood flow issues, 13 were in the heparin group and 12 were in the bicarbonate group. Out of these 25 cases, only 12 individuals (7 in the heparin group and 5 in the bicarbonate group) experienced catheter dysfunction.

The above study showed that sodium bicarbonate is as effective as classic unfractionated heparin in the prevention of catheter lumen thrombosis. It also provides a cost-effective alternative for cases where heparin is not suitable.

A recent study suggests that VLA1553 batches are both safe and immunogenic. This study’s findings were published in the Journal of travel medicine.

This was a phase 3, randomized, double-blinded, and focused on lot-to-lot consistency trial that included 408 healthy adults (aged 18-45 years). The primary endpoint of the study was to compare the geometric mean titre (GMT) ratios of chikungunya virus (CHIKV)-specific neutralizing antibodies between three different batches of VLA1553, 28 days after the administration of the vaccine. Additionally, secondary endpoints included assessing the immunogenicity and safety of the vaccine over a period of 6 months post-vaccination.

GMTs were similar among the batches that met the criteria for equivalence. The average GMT (measured by fifty percentage CHIKV micro plaque neutralization test; μPRNT50) reached 2643 at 28 days post-vaccination and dropped to 709 at 6 months post-vaccination. At 28 days post-vaccination, a high seroresponse rate (μPRNT50 titre ≥ 150 considered protective) was seen in 97.8% of participants, maintained at 96% at 6 months post vaccination. Following the administration of VLA1553 immunization, adverse events (AEs) were reported by 72.5% of the participants with no significant variations observed between the different batches. Generally, AEs were mild or moderate and resolved without any sequela, typically within 3 days.

Thus, it can be concluded that all three batches of VLA1553 were found to be safe and immunogenic. These findings emphasize the potential of VLA1553 as a vaccine for effectively preventing CHIKV disease in individuals residing in or visiting areas where the disease is prevalent.

According to a recent study, the desensitizing paste with 8% L-arginine, calcium carbonate, and potassium nitrate effectively blocked dentinal tubules and minimized dentin permeability. It alleviated both immediate and prolonged dentin hypersensitivity to different stimuli, demonstrating its potential role in the treatment of dentin hypersensitivity. This study's findings were published in the journal, BMC oral health.

The dentin surfaces of 24 third molars, each with a thickness of 2 mm were divided into two groups of 12. The experimental paste was given to one group, whereas the other group received a placebo devoid of a desensitizer. Scanning electron microscopy (SEM) and dentin permeability measurement were used to assess the permeability and sealing ability. The effects of the pastes on hypersensitivity were examined in a triple-blind, randomized clinical trial involving 16 eligible patients. Patients responsiveness to touch, cold, and spontaneous stimuli was measured at different time points following treatment using the VAS scale. Statistical examinations, such as Shapiro-Wilk, Friedman, Mann-Whitney U, and Wilcoxon tests, were conducted to evaluate the data.

In the permeability test, the experimental group demonstrated a significant decrease in dentin permeability (P = 0.002) compared to the control group (P = 0.178). Examination of SEM images revealed that most dentinal tubules in the intervention samples were occluded. Clinically, both groups experienced a notable reduction in all three types of sensitivity evaluated throughout the study. However, there was no significant differences in sensitivities between the two groups, except for cold sensitivity at three months post-treatment (P = 0.054).

The above study demonstrated that by using a desensitizing paste composed of 8% L-arginine, calcium carbonate, and potassium nitrate, the dentinal tubules were effectively blocked and dentin permeability was minimized. It successfully relieved both immediate and long-lasting dentin hypersensitivity caused by various stimuli, showcasing its promising application in the treatment of dentin hypersensitivity.

In a recent systematic review and meta-analysis, the presence of chronic sinonasal inflammation shows a significant correlation with nasopharyngeal carcinoma. Findings of this study were documented in the American Journal of Otolaryngology.

This meta-analysis involved a comprehensive search of four international databases from 1^st January 1973 to 28^th March 2022 for studies addressing sinonasal inflammation and NPC in adults (greater than 18 years old). Case-control, cohort, or cross-sectional studies were included that explored the association between a prior history of sinonasal inflammation and the risk of developing NPC. The incidence of nasopharyngeal carcinoma (NPC) in patients with prior sinonasal inflammation is the outcome.

A total of eight studies, comprising 8,245 individuals diagnosed with NPC and 1,036,087 individuals without NPC, were examined. The overall odds ratio for developing NPC following sinonasal inflammation was found to be 1.81 (95% confidence interval 1.73-1.89). Chronic rhinosinusitis (CRS) exhibited a stronger association with an increased risk of NPC, with an odds ratio of 1.78 (95% confidence interval: 1.68-1.90), in comparison to allergic rhinitis (AR) (odds ratio of 1.60; 95% confidence interval: 1.52-1.68).

Thus, it can be concluded that chronic sinonasal inflammation is strongly linked to nasopharyngeal carcinoma. It is important to thoroughly examine the cause-and-effect relationship and the potential effects of targeted screening using large-scale prospective studies.

A recent study demonstrated that lower ureteric stones can be effectively treated with both silodosin and mirabegron. Furthermore, when these medications are used together, they have been found to increase the rate of stone expulsion and reduce the duration of expulsion. This study’s findings were published in the journal, International Urology and Nephrology. 

This study included 105 patients, aged 20 to 56 years, who were diagnosed with a single radiopaque distal ureteral stone measuring ≤ 10 mm. The individuals were randomly allocated into three groups, each group containing 35 participants. Group A received an 8 mg daily dose of silodosin, group B was given 50 mg of mirabegron once daily, and group C received a combination of both medications. Treatment was given until the stone passed or for a maximum of four weeks. The stone-free rate was assessed by analyzing KUB films with or without ultrasonography.

Stone expulsion rate was higher in group C in comparison to groups A and B. The mean (standard deviation) time for expulsion of the stone in group A, group B, and group C was 14 ± 2.3 days, 11 ± 3.1 days, and 7 ± 2.2 days, respectively. Group C exhibited a significantly shorter stone expulsion time when compared to groups A and B. The incidence of renal colic in group C was significantly lower than that in groups A and B, leading to a decreased need for analgesics. Anejaculation was significantly more frequent in the silodosin group (73.9%) and combination group (84%) than in the mirabegron group.

Thus, it can be concluded that both silodosin and mirabegron are effective treatments for lower ureteric stones. Additionally, when these medications are utilized in combination, they have been shown to increase the rate of stone expulsion and decrease the duration of expulsion.

According to a recent study, soaking dentures in 1% sodium hypochlorite for 10 minutes without any brushing was found to be a simple, quick, affordable, and efficient way to clean the dentures of hospitalized patients. This study’s results were published in the Journal of applied oral science.

The maxillary complete dentures of 340 hospitalized participants were subjected to random cleaning using 17 different protocols (n=20 participants). The cleaning methods included brushing with distilled water, neutral liquid soap, or toothpaste, (considered as controls), as well as immersion in chemical solutions such as 1% sodium hypochlorite, alkaline peroxide, 0.12% or 2% chlorhexidine digluconate. Additionally, some dentures were subjected to microwave irradiation (650 W for 3 min), either alone or in combination with brushing. The effectiveness of these protocols was assessed by evaluating the biofilm of the intaglio surface of the maxillary complete dentures before and after cleaning. Two methods used for evaluation include : microbiological quantitative cultures on blood agar and Sabouraud Dextrose Agar (CFU/mL) as well as denture biofilm coverage area (%). The collected data were analyzed using the Wilcoxon and Kruskal-Wallis tests.

Significant reductions in the percentage area of denture biofilm and microbial and fungal load were achieved by all 17 protocols. The most significant reductions in denture biofilm area were observed with 1% hypochlorite solution with or without brushing, and with 2% chlorhexidine solution and microwave irradiation combined with brushing. The greatest reductions in microbial and fungal load were noted in groups that used 1% hypochlorite solutions and 2% chlorhexidine, as well as microwave irradiation, regardless of brushing .

Thus, it can be concluded that a single immersion of dentures in 1% sodium hypochlorite for 10 minutes, without brushing is a simple, quick, cost-effective, and efficient method for cleaning dentures in hospitalized patients.

A recent study suggests that patients with metastatic castration-resistant prostate cancer (mCRPC) and BRCA alterations showed clinically relevant outcomes when treated with niraparib plus abiraterone acetate and prednisone (AAP). This study’s results were published in the Annals of Oncology.

The phase 3, MAGNITUDE trial included 212 HRR+ patients with/without BRCA1/2 alterations. They were randomized in a 1:1 ratio to receive 200mg of niraparib orally plus AAP (1000 mg/10 mg orally) or placebo plus AAP. At the second prespecified interim analysis (IA2), the secondary endpoints assessed were time to symptomatic progression, time to initiation of cytotoxic chemotherapy and overall survival (OS).

It was found that at IA2 with 24.8 months of median follow-up, niraparib plus AAP showed significantly prolonged radiographic progression-free survival (rPFS) (19.5 versus 10.9 months; hazard ratio (HR) = 0.55 [95% confidence interval (CI) 0.39-0.78] consistent with the first prespecified interim analysis. Similarly, in the total HRR+ population, rPFS was also prolonged. In the niraparib plus AAP group, time to symptomatic progression and time to initiation of cytotoxic chemotherapy showed improvements. Even the analysis of OS with niraparib plus AAP in the BRCA1/2 subgroup demonstrated a lower hazard ratio.

From the above results, it is clear that niraparib plus AAP in patients with BRCA1/2-altered mCRPC, may demonstrate an improved rPFS and other clinically relevant outcomes.
