C-reactive protein (CRP) is a nonspecific biomarker for systemic inflammatory response and is linked to the prognosis of breast cancer (BC); however, few studies have investigated the correlation between CRP and the effectiveness of neoadjuvant chemotherapy treatment for BC. We recruited 177 patients with BC who underwent neoadjuvant chemotherapy in our clinical trial. the median CRP level (0.24 mg/L), patients were categorized into high and low groups. We examined the relationship between CRP levels and various clinicopathological factors, including pathological complete response (pCR), using the chi-square test or Fisher exact test. ⋯ The areas under the curve was 0.670 (95% CI: 0.550-0.792, P < .001). Multivariate logistic analysis showed that the CRP level was a significant independent predictor of pCR (OR = 5.882, 95% CI: 1.470-28.57, P = .017). High CRP levels were found to be associated with a higher pCR rate, indicating their independent predictive value in determining the efficacy of neoadjuvant chemotherapy in hormone receptor-positive BC patients.

The correlation between rapid eye movement sleep and nocturnal hypertension in patients with obstructive sleep apnea: A retrospective study.
Obstructive sleep apnea (OSA) is a respiratory disease closely associated with hypertension and heart disease. This study aimed to evaluate the diagnostic value of rapid eye movement (REM) sleep during nocturnal hypertension in OSA patients. We selected 194 patients who underwent polysomnography (PSG) at the Respiratory and Critical Care Medicine Department of Jiading District Central Hospital in Shanghai between January 2021 and August 2023. ⋯ Receiver operating characteristic curve analysis showed that the REM-AHI had an area under the curve of 0.721 (95% confidence interval, 0.641-0.801; P < .001) for diagnosing nocturnal hypertension in patients with OSA, with a maximum Youden index of 0.379. The optimal critical value of the REM-AHI was 23.6 times/h, with a sensitivity of 64.2% and specificity of 73.7%. REM sleep is closely related to nocturnal hypertension, and patients with OSA are more prone to cardiovascular events.

Piriformis syndrome, which is seen as the cause of 0.3% to 6% of low back pain, is a painful condition that occurs as a result of compression of the piriformis muscle on the sciatic nerve. Although there are many studies in the literature about piriformis syndrome, no bibliometric analysis has been found. This study aims to evaluate piriformis syndrome and conduct a bibliometric analysis of studies related to piriformis muscle and syndrome. ⋯ The findings obtained in this study are thought to be important for understanding to providing literature with new perspectives on this subject. They will also focus on the missing parts of the subject from this perspective. Also, this study would provide a novel perspective to the studies about piriformis syndrome and contribute to the researchers about the limits of the topic, and being aware of the active journals that publish papers on this issue would facilitate the work of the researchers.

To evaluate the long-term clinical outcomes of iodine-125 low dose-rate brachytherapy (LDR-BT)-based treatment approaches for ≤ cT3 prostate cancer (PC) patients in China, as well as the effects on the PC immune microenvironment. Data was retrospectively collected from 237 patients with ≤ cT3 PC who were treated with radical prostatectomy (RP) or LDR-BT alone or in combination with androgen deprivation therapy (ADT), and biochemical progression-free survival (bPFS), prostate cancer-specific survival (PCSS) and overall survival (OS) rates were compared. In 63 cases, PC patients received RP after biopsy, received at least 6 months of ADT before RP, or received LDR-BT and deferred limited transurethral resection of the prostate (TURP). ⋯ LDR-BT monotherapy and combination therapy with external beam radiotherapy (EBRT) and ADT are suitable treatment approaches for low-risk and intermediate- or high-risk PC, respectively. Most TILs in PC are not tumor antigen-specific T-cells. LDR-BT can stimulate anti-tumor immunity during a narrow time window and should be combined with immunotherapy as an auxiliary therapy.

Lateral center-edge angle in femoroacetabular impingement: from the sourcil or the rim of the acetabulum?
The correlation between clinical outcomes and preoperative/postoperative measures of the lateral center-edge angle (LCEA) will help establish the cutoff values for this measurement and determine whether to obtain it from the lateral acetabular rim (LCEAR) or the lateral end of the sourcil (LCEAS). The hypothesis was that the LCEAS would be more sensitive than the LCEAR. An upper cutoff value of LCEA could predict better functional outcomes in FAI patients. 106 patients (103 unilateral, 3 bilateral) who underwent hip arthroscopy surgery due to FAI and had a minimum 2-year follow-up were included. ⋯ LCEAS seems more predictive of clinical significance than LCEAR. However, predictivity exceeds the acceptable limit when they are measured together. The upper values for LCEAS and LCEAR seem to be 24° and 35°, respectively.
