AI Article Synopsis
- Mean platelet volume (MPV) is being studied as a potential marker for cardiovascular disease, particularly focusing on its relationship with androgen hormones and insulin resistance (IR) in nonobese women with polycystic ovary syndrome (PCOS).
- A study involving 136 nonobese PCOS patients and 59 healthy controls found no significant differences in MPV values between the groups, with both showing comparable levels.
- However, patients with high androgen levels had lower MPV compared to those with normal levels, indicating a negative correlation between androgen levels and MPV, while insulin resistance did not appear to influence MPV values.
Article Abstract
Background: Mean platelet volume (MPV) is generally accepted as a new marker of cardiovascular disease risk in several studies.
Objectives: This study aimed to determine the association of MPV with androgen hormones and insulin resistance (IR) in nonobese patients with polycystic ovary syndrome (PCOS).
Patients And Methods: A total of 136 patients with newly diagnosed reproductive-age PCOS (regarding the criteria of new PCOS phenotypes, based on the Rotterdam criteria) who were nonobese with the mean age of 25 years (25.39 ± 5.51) and mean body mass index (BMI) of 21 kg/m(2) (22.07 ± 2.13) were included. In addition, 59 healthy subjects with mean age of 26 years (22.07 ± 2.13) and mean BMI of 22 kg/m(2) (21.52 ± 3.84) were recruited as control. Total blood count (including MPV), total testosterone, free testosterone, dehydroepiandrosterone-sulfate (DHEAS), and androstenedione levels were recorded. IR was calculated from blood chemistry measurements of fasting insulin and glucose according to updated homeostasis model assessment.
Results: No differences were observed in mean MPV values between patients and control group (9.02 fL (8.5-10.1) and 8.9 fL (7.7-9.1), respectively; P = 0.777). MPV values were similar among nonobese patients with and without IR and control subjects (P > 0.05). We detected significantly lower values of MPV in patients with hyperandrogenemia in comparison to patients with normal androgen levels (8.7 and 9.5 fL, P = 0.012). There was a negative correlation between total testosterone, DHEAS, and MPV (P = 0.016, r = -0.229; and P = 0.006, r = -0.261, respectively). Multiple logistic regression analyses confirmed the independence of these associations.
Conclusions: Our study revealed that nonobese women with and without PCOS have similar MPV values. While IR does not have any effect on MPV, elevated androgen levels are associated with a low MPV in nonobese patients with PCOS.

The prototype of a biomimetic multi-spiked connecting scaffold (MSC-Scaffold) represents an essential innovation in the fixation in subchondral trabecular bone of components for a new generation of entirely cementless hip resurfacing arthroplasty (RA) endoprostheses. In designing such a functional biomaterial scaffold, identifying the microstructural and mechanical properties of the host bone compromised by degenerative disease is crucial for proper post-operative functioning and long-term maintenance of the endoprosthesis components. This study aimed to explore, depending on the occurrence of obesity, changes in the microstructure and mechanical properties of the subchondral trabecular bone in femoral heads of osteoarthritis (OA) patients caused by the MSC-Scaffold embedding.

: This study aimed to examine the connection between craniofacial morphology, particularly the horizontal and vertical dimensions of the mandible, and the severity of obstructive sleep apnea (OSA) in non-obese adult males by utilizing a cephalometric analysis and introducing a new skeletal ratio index. : A cohort of 44 non-obese adult males with OSA, diagnosed via the apnea-hypopnea index (AHI) from polysomnographic recordings, was evaluated using a lateral cephalometric analysis. OSA severity was classified as mild (5 ≤ AHI < 15) in 19 patients, moderate (15 ≤ AHI < 30) in 15 patients, and severe (AHI ≥ 30) in 10 patients.

Background & Aims: Dilated intercellular space (DIS) in esophageal epithelium, a sign of impaired barrier function, is a characteristic finding of GERD that also is found in obese patients without GERD. We have explored molecular mechanisms whereby adipose tissue products might impair esophageal barrier integrity.
Methods: We established cultures of visceral fat obtained during foregut surgery from obese and non-obese patients.

Aims/introduction: Fatty acid-binding protein (FABP) 4, which acts as an adipokine secreted by adipocytes, macrophages, and capillary endothelial cells, is expressed in injured glomerular cells. It has been reported that urinary (U-) FABP4 is associated with renal dysfunction and proteinuria in several glomerular kidney diseases. However, the clinical significance of U-FABP4 in diabetic kidney disease (DKD) remains undetermined.
