Introduction: Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome. Surgical studies are often reported in small cohorts and with limited information on functional improvement. This study reports the clinical and functional outcomes after HAT repair.
Methods: 112 patients with symptomatic HAT tears, diagnosed via magnetic resonance imaging, underwent open bursectomy, V-Y lengthening of the iliotibial band, debridement of the diseased tendon, decortication of the trochanteric foot-plate and reattachment of the tendon with suture anchors, augmented with a LARS ligament through a trans-osseous tunnel. Patients were evaluated pre-surgery and at 3, 6 and 12 months post-surgery using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, hip range of motion, 6-minute walk and 30-second single leg stance tests. Maximal isometric hip abduction strength (HAS) was assessed and limb symmetry indices (LSIs) were calculated between the operated and non-operated limbs. Patient satisfaction and perceived global rating of change (GRC) was evaluated. Analysis of variance evaluated improvement over time.
Results: There was a significant improvement (p<0.05) in all clinical and functional measures. HAS significantly improved over time (p<0.002) and all LSIs were >85% at 12 months. At 12 months, a mean GRC score of 3.5 (range -1 to 5) was reported, while 96% of patients were satisfied with their surgical outcome. There was a 2.7% (n = 3) failure rate at 12 months.
Conclusions: HAT reconstruction, augmented with a synthetic ligament, demonstrated significantly improved clinical and functional outcomes, high levels of patient satisfaction and a low failure rate to 12 months post-surgery.

The current unavailability of efficient myocardial repair therapies constitutes a significant bottleneck in the clinical management of myocardial infarction (MI). Ginsenoside Rb1 (GRb1) has emerged as a compound with potential benefits in safeguarding myocardial cells and facilitating the regeneration of myocardial tissue. However, its efficacy in treating MI-related ischemic conditions is hampered by its low bioavailability and inadequate angiogenic properties.

Background And Objective: Inferring large-scale brain networks from functional magnetic resonance imaging (fMRI) provides more detailed and richer connectivity information, which is critical for gaining insight into brain structure and function and for predicting clinical phenotypes. However, as the number of network nodes increases, most existing methods suffer from the following limitations: (1) Traditional shallow models often struggle to estimate large-scale brain networks. (2) Existing deep graph structure learning models rely on downstream tasks and labels.

This part reviews the management of chronic cough and proposes a management algorithm. Despite proven improvements in quality of life following chronic cough treatment, a clear understanding of the disease and the evidence for the efficacy of some treatments remain vague. Eight key questions regarding the treatment in the uncertain areas were systematically addressed based on the PICO framework and applying the GRADE system for evidence synthesis to provide the strength of recommendation and quality of evidence for key questions, with narrative components for the description of other chronic cough treatment including non-pharmacological therapy.

Chronic cough is a common clinical condition requiring comprehensive assessment. This review employs a symptom-focused approach, prioritizing the presenting symptom of "chronic cough" to mirror real-world clinical practice. Ten key questions regarding the investigations in the uncertain areas were systematically addressed based on the PICO framework and applying the GRADE system for evidence synthesis to provide the strength of recommendation and quality of evidence for key questions.

The objective of this study was to examine the efficacy of the concurrent utilization of estradiol valerate and kuntai capsule (a Chinese herbal preparation) in addressing premature ovarian failure (POF) and its ramifications for ovarian hemodynamics and sex hormone levels. A retrospective study of 104 patients with POF was conducted, dividing them into control (n=50) and observation groups (n=54). The control group received estradiol valerate, while the observation group received estradiol valerate and KunTai capsules over 12 weeks.
