Observational Study
The impact of postoperative nasal oxygen therapy on early-stage corneal edema in cataract patients with dynamic Scheimpflug analyze: A retrospective study.
This study aimed to assess the impact of 6 hours of postoperative nasal oxygen therapy on early-stage corneal edema in patients with nuclear cataracts of grades 3 to 4. A retrospective study involved 49 patients (49 eyes) with grades 3 to 4 nuclear cataracts undergoing phacoemulsification and intraocular lens implantation from September 2021 to September 2022. The oxygen group (27 cases) received postoperative nasal oxygen therapy for 6 hours, while the control group (22 cases) received no additional treatment. ⋯ Statistically significant differences were found in overall COD, COD within specific depth and thickness ranges, and COD within the anterior layer (120 μm thickness) at 24 hours postoperatively (all P < .05). No significant difference was observed in COD values within the central and posterior layers (60 μm thickness) between the 2 groups (all P > .05). Postoperative nasal oxygen therapy for 6 hours immediately after surgery could alleviate the severity of early-stage corneal edema in patients with nuclear cataracts of grades 3 to 4.

Prevalence of and factors associated with cognitive frailty in elderly patients with chronic obstructive pulmonary disease: A cross-sectional study.
The status of cognitive frailty in elderly patients with chronic obstructive pulmonary disease (COPD) and its influencing factors in China remains unclear. This study aimed to investigate the prevalence of and factors associated with cognitive frailty in elderly patients with COPD. This cross-sectional study enrolled elderly patients with stable COPD between May and November 2022 from the Respiratory Department of the First Affiliated Hospital of Zhengzhou University and the Fifth Affiliated Hospital of Zhengzhou University. ⋯ Binary logistic regression analysis showed that sex (odds ratio [OR] = 0.009; 95%CI: 0.001-0.770; P = .038), depression (OR = 17.780; 95%CI: 1.092-289.478; P = .043), modified Medical Research Council grade 1-3 (OR = 28.394-4095.683; 95%CI: 1.086-4,592,652.211; P < .05), global initiative for chronic obstructive lung disease grade 2 and 3 (OR = 32.508-282.072; 95%CI: 1.101-12,516.874; P < .05), and frequencies of acute exacerbations of COPD and hospitalizations within 1 year of 2 times (OR = 21.907; 95%CI: 4.587-104.622; P < .001) were independently associated with cognitive frailty. The prevalence of cognitive frailty in elderly patients with stable COPD was high. Female, depression, modified Medical Research Council grade, global initiative for chronic obstructive lung disease grade, and frequencies of acute exacerbations of COPD and hospitalizations within 1 year might be the factors independently associated with cognitive frailty, educational level might be a protective associated factor for cognitive frailty.

The different variants of renal angiomyolipoma pose diagnostic and therapeutic challenges in clinical practice. We report a rare case of renal solid-cystic angiomyolipoma, with the aim of offering new insights into the preoperative imaging assessment of renal masses. ⋯ Renal angiomyolipoma is usually easily distinguishable on imaging, but this case aims to alert clinicians to differentiate the rare variants of renal angiomyolipoma from other renal tumors. In the future, more cases are needed to summarize the characteristics of different variants of renal angiomyolipoma.

The pectoralis major and minor muscles, located in the anterior chest wall, are crucial for upper limb movements. ⋯ This case report is significant due to the rarity of this condition without accompanying anatomical variations. Understanding this variant is valuable for clinical situations involving the shoulder and thorax region, such as trauma to the proximal third of the humerus, clavicular region, suprascapular region, and anterior chest wall. It may complicate conservative and/or surgical treatments due to different functional and irrigation patterns in the area and is also important for educating future professionals.

Effect of different growth hormone pretreatment times in assisted reproductive therapy for patients with diminished ovarian reserve: A retrospective pilot cohort study.
This study aimed to evaluate the effect of different growth hormone (GH) pretreatment times in assisted reproductive therapy in patients with diminished ovarian reserve (DOR). A retrospective pilot cohort analysis was performed on patients with DOR receiving GH pretreatment in the Assisted Reproduction Unit of Sir Run Run Shaw Hospital. A total of 1459 patients met the criteria and were divided into four groups according to GH pretreatment time as follows: 53 were in the 2-month pretreatment group (GH1), 400 were in the 1-month pretreatment group (GH2), 414 were in the ovulation induction period pretreatment group (GH3), and 592 were in the non-GH pretreatment group (control group). ⋯ These findings suggest that the GH pretreatment time was appropriately prolonged, and the number of oocytes retrieved nominally increased. In patients with DOR, GH pretreatment improved treatment outcomes. More than 1 month of GH pretreatment did not increase the number of oocytes retrieved.
