A key factor in evolution is reproduction, which is also a major concern in medicine. Evolutionists have proposed many theories and hypotheses to explain the low fertility rates of modern industrial societies, which are contrary to maximization of biological fitness. Given that childbirth is the most significant factor affecting re-productive fitness, it is likely that a variety of psychological modules related to childbirth behavior and intentionevolved over time. Several evolutionary psychological modules have been proposed in relation to reproduction, including sexual desire, status-seeking, a need for nurturing, and the desire for children. Previously adaptive psychological modules may now be expressed maladaptively due to the discrepancy between the Environment of Evolutionary Adaptedness (EEA) and the environment of modern industrial society. Several evolutionary ecological factors influence childbirth intention in modern society, including individual personality factors, childhood life his-tory experiences, and socioecological factors throughout reproductive life. By focusing on mental, social, and ecological factors, this review examines several hypothetical models relating to evolutionary psychological factors and childbirth decisions in modern industrial society, as well as a possible explanation for the low birth rate.

Purpose:
Suprascapular neuropathy can be caused by a solid mass, transverse scapular ligament hypertrophy, paralabral cyst, or dilatation of a suprascapular vein. Studies have measured the size of the cyst and veins using magnetic resonance imaging (MRI) to aid diagnosis of suprascapular neuropathy. However, it is often difficult to determine the size of a cyst and vein. we measured cyst and vein size as potential diagnostic markers for suprascapular neuropathy.
Methods:
This study retrospectively enrolled 118 patients diagnosed with a paralabral cyst in a clinic from January 2016 to December 2019. After excluding other neuropathies and cysts not related to the course of the suprascapular nerve, a total of 67 patients were analyzed. The cyst diameter, cyst volume, and vein diameter were measured engorgement by MRI in axial, coronal, and sagittal T2-weighted images. Cutoff values were established based on Youden’s index.
Results:
There was no significant difference between the neuropathy and control groups in cyst coronal diameter, but the neuropathy group had greater sagittal (p=0.001), axial (p=0.001), and maximum cyst diameters (p=0.005), cyst volume (p=0.003), and coronal (p=0.002), axial (p=0.001), and maximum vein diameters (p=0.001).
Conclusion
In suprascapular neuropathy symptomatic patients, electromyographyerve conduction velocity tests are eventually needed when in doubt. However, measuring cyst diameter, volume, and suprascapular vein diameter as a screening test could be considered.

STUDY DESIGN: Data of 22 patients with congenital scoliosis who underwent single stage posterior hemivertebrectomies and short segment fixation with a minimum follow-up of 2 years in our centre were studied retrospectively. PURPOSE: To report the efficacy of posterior hemivertebrectomy in single vs multiple level hemivertebra and compare their results. OVERVIEW OF LITERATURE: Single stage hemivertebrectomy is a standard procedure for single level hemivertebra. Results of multiple level hemivertebrectomies have not been reported. METHODS: Twenty-two patients (9 male and 13 female) with the mean age of 11.2 years (range, 2 years 4 months to 24 years 10 months) and a mean follow up of 32 months (range, 4 to 73 months) were studied retrospectively and their results were compared. RESULTS: Average number of hemivertebrae removed was 1.46 (range, 1 to 3). Mean preoperative and postoperative coronal cob angle was 48.7° (range, 22° to 80°) and 24.2° (range, 7° to 41°), respectively (p<0.001). Mean preoperative and postoperative sagittal cobb angle was 32.1° (range, 7° to 76°) and 13.6° (range, 0° to 23°), respectively (p<0.005). Mean coronal and sagittal cob correction percentage achieved was 50.2% and 51.8% respectively. Mean follow-up was 49 months (range, 30 to 84 months). Mean loss of coronal and sagittal correction at final follow-up was 4% (0% to 13.6%) degrees and 3.5% (0% to 20%), respectively. CONCLUSIONS: Posterior hemivertebrectomy in congenital scoliosis is a safe treatment option for up to 3-level hemivertebrae. Excision of thoracolumbar hemivertebrae results in better correction than thoracic and lumbar hemivertebrae.

Owing to recent advancements in various postoperative treatment modalities, such as radiation, chemotherapy, antiangiogenic treatment, and immunotherapy, the radiological and clinical assessment of patients with isocitrate dehydrogenase-wildtype glioblastoma using post-treatment imaging has become increasingly challenging. This review highlights the challenges in differentiating treatment-related changes such as pseudoprogression, radiation necrosis, and pseudoresponse from true tumor progression and aims to serve as a guideline for efficient communication with clinicians for optimal management of patients with post-treatment imaging.

The paradigm of isocitrate dehydrogenase (IDH)-wildtype glioblastoma is rapidly evolving, reflecting clinical, pathological, and imaging advancements. Thus, it remains challenging for radiologists, even those who are dedicated to neuro-oncology imaging, to keep pace with this rapidly progressing field and provide useful and updated information to clinicians. Based on current knowledge, radiologists can play a significant role in managing patients with IDH-wildtype glioblastoma by providing accurate preoperative diagnosis as well as preoperative and postoperative treatment planning including accurate delineation of the residual tumor. Through active communication with clinicians, extending far beyond the confines of the radiology reading room, radiologists can impact clinical decision making. This Part 1 review provides an overview about the neuropathological diagnosis of glioblastoma to understand the past, present, and upcoming revisions of the World Health Organization classification.The imaging findings that are noteworthy for radiologists while communicating with clinicians on preoperative and immediate postoperative imaging of IDH-wildtype glioblastomas will be summarized.
