Anterior cruciate ligament injuries are commonly seen in orthopedic surgery practice. Although anterior cruciate ligament reconstruction (ACLR) has come a long way, the causes of failure have yet to be fully understood.

The aim of this study was to investigate whether or not the intraoperative 4-strand hamstring autograft diameter does in fact influence the failure rates of ACLR.

Retrospective intraoperative data were collected from ACLR patients from the only tertiary center available in Kuwait. PI3K inhibitor Patients who underwent ACLR from 2012 to 2018 for isolated ACL injuries were included in this study, allowing for a 24 month follow-up period The cohorts were categorized into 3 groups patients with graft size≤8mm, 2, patients with graft sizes≥8mm with 4-strands and patients with graft sizes≥8mm with 4-strands or more. ANOVA analysis was applied to address group differences between mean graft size and strand numbers and subsequently the failure rates for each group. In addition, the Mann-Whitney U test was used to investigate the relationship between revision and initial ACL graft size.

Out of the 711 out of 782 patients were included in this study. Only 42.6% of the patients did not need more than 4-strands to achieve an 8mm sized autograft. The patients who had autografts≤8mm in this study accounted for 17.1% of the population. About 7.2% of these patients required revision surgery. Patients with a 4-strand autograft size that was less than 8mm were 7.2 times more at risk for ACLR failure (RR=7.2, 95% CI 6.02; 8.35, p=0.007).

There is a significant correlation between 4-strand autograft diameter size and the need for ACLR revision surgery.

Not using a tourniquet could improve early postoperative pain, range of motion (ROM), length of stay (LOS), and thromboembolic risk in patients undergoing total knee arthroplasty (TKA). Our aim was to compare these factors, intraoperative blood loss, and gender-related outcomes in patients undergoing primary TKA with or without a tourniquet.

We performed a retrospective cohort study of 97 patients undergoing TKA with or without tourniquet from 2018 to 2020. Revisions and bilateral TKAs were excluded. Blood loss was estimated using a validated formula. Postoperative pain was tested using the visual analogue scale (VAS). ROM and quadriceps lag were assessed by a physiotherapist on a postoperative day 2 and discharge. The index of suspicion for a thromboembolic event was defined as the number of embolic-related investigations ordered in the first 6 months post-surgery. The Shapiro-Wilk test was used to assess the distribution of the data, Mann-Whitney for the continuous variables, and Fischer's test for the d no difference in pain, ROM, LOS, and quadriceps lag on day 2 and at discharge. There was one thromboembolic event in the tourniquet group, but the thromboembolic index of suspicion did not differ (p=0.53). With tourniquet use, women had a significantly lower day 2 maximum flexion than men (71.56° vs. 84.67°, p=0.02). In this retrospective cohort study, the results suggest that tourniquet use is associated with lower blood loss and similar postoperative pain, range of motion, quadriceps lag, length of stay, and thromboembolic risk. There might be some differences between how men and women tolerate a tourniquet, with women having worse short-term outcomes compared to men.
Regional citrate anticoagulation (RCA) during intermittent hemodialysis (iHD) effectively prevents circuit clotting without systemic anticoagulation and is especially beneficial for patients at increased bleeding risk. The performance of RCA under different iHD modes is not well documented.

We retrospectively studied all consecutive iHD sessions with our RCA protocol during a 3-year period. We compared low-flux iHD, high-flux iHD, and online post-dilution hemodiafiltration (oHDF) with regard to flow rates, calcium changes, metabolic outcomes, and complications. We used a calcium-free dialysate, concentrated sodium citrate (0.5M), and calcium chloride substitution (0.5M). Several safety measures were implemented to prevent human errors.

We performed 111 RCA treatments in 66 cases. Seven sessions were prematurely stopped due to malfunctioning vascular access or pre-existing severe hypotension. The other 104 treatments (94%) consisting of 28 low-flux iHD, 31 high-flux iHD, and 45 oHDF were completed without clotting or complications. The protocol settings were used without adaptations in 75% of low-flux iHD, 93% of high-flux iHD, and 84% of oHDF sessions. Minor adjustments of the calcium flow rate were made within the first 2 hours. We did not observe any clinically relevant differences between the three modes regarding flow rates, systemic iCa, post-filter iCa, pH, or bicarbonate levels.

Our protocol was similarly suitable for low-flux iHD, high-flux iHD, and oHDF, with only minor adaptations. Clotting, relevant calcium changes, metabolic or other complications were not observed. Our protocol could serve as a template for a commercial RCA solution in iHD.

The therapeutic effect of plasma exchange (PLEX) combined with conventional treatment in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) remains controversial.

We searched PubMed, Embase, Cochrane Library, and China National Knowledge Infrastructure for randomized controlled trials (RCTs) and cohort studies that compared PLEX added to conventional therapy with conventional therapy only in active AAV.

19 studies were included for the meta-analysis. Compared with the conventional therapy group, the PLEX group had a significantly reduced risk of end-stage renal disease (ESRD) at 3months (odds ratio (OR) = 0.32, 95% confidence interval (CI) = 0.16 - 0.66, p=0.002, I
= 0%), and the ANCA titerwas also decreased (OR = 40.99, 95% Cl = 23.56 - 58.43, p<0.00001, I
= 42%). The plasma and non-plasma exchange groups had no substantial differences in terms of short- and long-term outcomes, including all-cause mortality, ESRD risk at 12 months and 5 years, remission rate, serum creatine levels, or serious adverse events.

PLEX therapy was not associated with favorable long-term outcomes, although the results showed benefits in the incidence of ESRD rate at 3 months and ANCA titers in patients with AAV. No advantage of PLEX added to conventional therapy on mortality and complete remission was observed in patients with diffuse alveolar hemorrhage. Further high-quality multicenter RCTs with a high number of participants are required to assess the potential efficacy of PLEX in active AAV.

According to recent studies, the development of acute kidney injury (AKI) in severe cases of COVID-19 infection significantly worsens the prognosis of these patients. The pathological changes in kidneys might be caused directly by the cytopathic effect mediated by local replication of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) or indirectly because of systemic immune response or hypercoagulation, so-called immunothrombosis. Other causes, such as hypovolemia and hypoxia, may also contribute to AKI. Acute kidney disease often develops in elderly patients with underlying comorbidities or in critically ill patients with severe respiratory failure. It is known that AKI is a risk factor for mortality in COVID-19 patients.
Percutaneous insertion of a peritoneal dialysis catheter (PDc) is an alternative to open surgical techniques, and the anatomical characteristics of the abdominal wall may predict PDc dysfunction. We evaluated the role of rectus abdominis muscle (RAM) thickness as a predictor of PDc dysfunction.

A prospective cohort of emergency-start PD patients (EmPD) who had their first percutaneous PDc insertion were included. PDc failure was defined as the removal of a PDc due to mechanical failure within the first 30 PD fluid exchanges. Clinical variables were recorded. The skin to parietal peritoneum depth and RAM thickness were determined by abdominal ultrasound. Univariate and multivariate logistic regression models were developed to test associations between clinical parameters and PDc dysfunction.

Over 6 months, 119 patients underwent PDc insertion; 73 (61.3%) were males, with a mean age of 46.0±17.8 years. The mean skin-to-peritoneum depth was 2.5±1.0 cm, the RAM thickness was 0.91±0.3 cm, and catheter implantation was successful in 116 (97.4%) patients. Insertion failed in 3 (2.5%) cases, and 30 (25.8%) patients presented with catheter dysfunction. Univariate analysis indicated that RAM thickness ≥1.0cm, skin-to-peritoneum depth >2.88cm, abdominal waist >92.5cm, and skin-to-RAM fascia distance >2.3cm were associated with PDc dysfunction; in multivariate logistic regression analysis, only greater RAM thickness remained a significant predictor (OR 1.6, 95% CI 1.38 - 1.88, p<0.001).

In EmPD patients, RAM thickness is associated with PDc dysfunction and could aid in identifying patients at risk for PDc dysfunction in emergency settings. Additional adequately powered studies are needed to confirm our findings.

The co-existence of two independent brain tumors at the same anatomical site is rare and occurs as a "collision tumor" or "tumor-to-tumor metastasis." In intracranial location, meningioma is the most common neoplasm in such coincidences.

We present a case involving a 31-year-old woman with a complex tumor consisting of chordoma and meningioma in the petroclival region. The patient presented with left facial numbness, ataxia, and left-sided hemiparesis. Computed tomography and magnetic resonance imaging showed a well-demarcated, intradural, extra-axial tumor mass in the petroclival region. After complete total resection, histopathological examination revealed two different parts of the tumor, consisting of chordoma and meningioma. Therefore, additional radiation therapy and adjuvant chemotherapy were given.

To the best of our knowledge, this is the first description of the simultaneous occurrence of chordoma and meningioma in the same anatomical location. In such a scenario, differential diagnosis of choroid meningioma and chordoma is required.
