AI Article Synopsis
- * The study analyzed four relevant studies involving 687 patients, finding that closed-box prostheses significantly reduced total blood loss compared to open-box prostheses for both unilateral and bilateral TKA.
- * No notable differences were observed in average transfusion units, length of hospital stay, or total operation time between the two types of prostheses, suggesting closed-box might be more effective specifically for minimizing blood loss.
Article Abstract
Purpose: Postoperative blood loss is a common complication following total knee arthroplasty (TKA). The authors aimed to analyze the significance of open versus closed-box prostheses in reducing blood loss after TKA.
Methods: PubMed, Cochrane, Scopus, and Web of Science were searched. Observational studies and clinical trials comparing the effect of open-box versus closed-box prostheses on blood loss following TKA were included. The primary outcome was total blood loss following TKA. Secondary outcomes included average transfused units and total operation time. Continuous data were represented as mean difference (MD) and CI, while dichotomous data were presented as odds ratio (OR) and CI. RevMan software version 5.4 was used to conduct the analysis.
Results: Four studies with a total number of 687 patients were included. The pooled analysis showed a statistically significant association between closed-box and decreased total blood loss following TKA compared with open-box (MD=173.19, 95% CI=88.77-257.61, value <0.0001). Similar findings were reported in unilateral TKA (MD=190.63, 95% CI=70.91-310.35, value=0.002), and bilateral TKA (MD=160.79, 95% CI=61.70-359.86, value=0.001). There was no significant difference between open and closed-box regarding average transfused units (MD=0.02, 95% CI=-0.07-0.11, value=0.68), blood transfusion rate (OR=1.38, 95% CI=0.85-2.26, value=0.20), length of stay (MD=0.06, 95% CI=-0.27 to 0.38, value=0.74), and total operation time (MD=1.08, 95% CI=-4.62 to 6.79, value=0.71).
Conclusion: Closed-box reduces the total blood loss following unilateral and bilateral TKA. More studies are warranted to explore the benefits of Closed-box in patients with high bleeding susceptibility.

This was an original article, and the objective of this study was to investigate the effects of bipolar transurethral plasma kinetic prostatectomy (TUPKP) on urodynamics and sexual function in benign prostatic hyperplasia (BPH) patients. One hundred and four BPH patients were divided into a control group and an intervention group. The control group received transurethral resection of prostate, while the intervention group received TUKEP.

: The ketogenic diet (KD) is widely used for weight management by reducing appetite, enhancing fat oxidation, and facilitating weight loss. However, the high content of total and saturated fats in a conventional KD may elevate low-density lipoprotein (LDL)-cholesterol levels, a known risk factor for cardiovascular diseases, highlighting the need for healthier alternatives. This study aimed to investigate the effect of a newly developed Healthy Ketogenic Diet (HKD) versus an Energy-Restricted Diet (ERD) on weight loss and metabolic outcomes among adults with obesity.

Background/objectives: Multilevel interventions have demonstrated efficacy in improving obesity and other related health outcomes. However, heterogeneity in individual responses indicates the need to identify the factors associated with responses and non-responses to multilevel interventions. The objective of this report is to identify the potential sources of heterogeneity through the exploration of the moderation effects of participant characteristics (sociodemographic and baseline physical/mental health) in the Strong Hearts, Healthy Communities-2.

The aim of our study was to examine the combined effects of tranexamic acid (TXA) and vancomycin powder (VP) on chondrocytes in vitro. Despite the use of TXA and VP being linked to a reduced risk of extensive postoperative blood loss and periprosthetic joint infections (PJIs) in TKA, the possible cytotoxic side effects on periarticular cell types remain unclear. Human chondrocytes were harvested from hyaline cartilage and expanded in monolayer culture before being simultaneously exposed to different concentrations of TXA and VP for varying exposure times.

Natural killer (NK) and CD8 T cell function is compromised in human immunodeficiency virus type 1 (HIV-1) infection by increased expression of inhibitory receptors such as TIGIT (T cell immunoreceptor with Ig and ITIM domains). Blocking inhibitory receptors or their ligands with monoclonal antibodies (mAb) has potential to improve antiviral immunity in general and facilitate HIV eradication strategies. We assessed the impact of TIGIT engagement and blockade on cytotoxicity, degranulation, and interferon-gamma (IFN-γ) production by CD8 T cells from persons living with HIV (PLWH).
