Alteration in gut microbial characteristics of patients with acromegaly.

PURPOSE: Studies on intestinal microbiota in acromegaly are scant. This study aimed to characterize the gut microbiome in patients with acromegaly. METHOD: Stool samples were collected from 11 patients newly diagnosed with acromegaly and 12 healthy controls matched for body mass index (BMI) and age after three days on a standard diet. Clinical and gut microbial composition assessments were performed for the two participant groups using 16S rRNA gene amplicon sequencing. RESULTS: There was no difference in the alpha diversity of the microbiota between the samples from patients with acromegaly and those from the healthy controls. Based on beta diversity measurements, differences in microbial community structures were found to be significant only when compared using the Jaccard similarity index. The corresponding Firmicutes/Bacteroidota ratio tended to be higher in individuals with acromegaly than in healthy controls. The mean relative abundance of Actinobacteriota was 2.3 times higher in the acromegaly patient group than in the control group. Eggerthellaceae, Christensenellaceae, and Bacteroidaceae were among the significantly abundant bacterial families in the samples from the acromegaly patient group, while Butyricicoccaceae and Tannerellaceae were decreased. At the level of the genus, the most discriminative features were the abundance of Prevotella 7, Bacteroides, Senegalimassilia, Enterohabdus, the Family XIII AD3011 group, Howardella, and Hungatella in the samples from the acromegaly patient group. In contrast, the Butyrivibrio and the Eubacterium eligens group were the most discriminative genera for the healthy controls and were significantly less abundant in patients with acromegaly. While there were no significantly differentiated taxa between the diabetic and non-diabetic subgroups, Prevotella_7 was significantly enriched in the osteoarthritis (OA) subgroup. No significant association was found between individual genera and growth hormone (GH) levels and insulin-like growth factor-1 (IGF-1) levels as well as the upper limit of normal (ULN). CONCLUSION: Although alpha and beta diversity were mainly similar between the two groups, significant differences were observed between the acromegaly group and the control group at the family and genus levels. These results suggest that the differences between the microbial communities in patients with acromegaly and those in healthy individuals consist primarily of compositional differences independent of abundance. Prospective studies are needed to further explore the clinical implications of gut microbiome dysbiosis in patients with acromegaly.

Traditional Societal Practices Can Avert Poor Dietary Habits and Reduce Obesity Risk in Preschool Children of Mothers with Low Socioeconomic Status and Unemployment.

Healthy nutritional habits are of vital importance for good health and quality of life for all individuals in all life stages. Nutritional habits shaped in early childhood set the foundation for future dietary practices applied through lifespan, hence informing risk towards chronic diseases. A key contributor to child health is maternal impact. A healthy childhood status translates into increased lifespan, health, and life-quality, as well as better family and social interactions and improved academic performance. These conditions can contribute to a healthier and more vibrant workforce, and thus extend positive impact on the economic and overall development of a country. Evidence related to maternal impact on childhood dietary habits is limited in Turkey, an emerging economy with notable disparities and a significant segment (approximately one third) of its 83 million population under the age of 30. Hence, the aim of this study was to investigate the relationship between the socioeconomic status (SES) of mothers on the dietary habits of their preschool children. A pilot cross-sectional observational study was conducted involving the mothers of 109 preschool children aged 4-6 years. Data on the nutritional status of children were collected through a food frequency questionnaire and a 24-h recall interview, while sociodemographic information was also collected, and statistical analyses conducted. An unexpected finding regarding the lack of association between the socioeconomic and employment status of mothers and the nutritional intakes of their children was observed. Interestingly, it appears that more traditional societal and nutritional practices typically undertaken in the case of lower SES, especially in more traditional settings like the case of Turkey, appear to extend a protective effect as per the nutritional habits and ensuing obesity risk in the case of children of women with lower SES. Another way to interpret our finding is that the difference in education and SES is not adequate to produce a significant effect in terms of children dietary intake. This is an interesting finding that warrants further study. Additionally, such studies serve to increase awareness about the importance of healthy nutritional practices in preschool children and the critical role of the mother on their nutritional status, particularly in the Turkish idiosyncratic setting.

Exodeviation following monocular myopic regression after laser in situ keratomileusis.

We report a 44-year-old woman with intermittent left exotropia of 35 prism diopters at distance who initially exhibited alignment of both eyes after bilateral laser in situ keratomileusis (LASIK). The exophoria was not preserved due to myopic regression in the dominant eye. An uneventful LASIK treatment was performed to correct -11.00 -0.50 x 130 in the right eye and -13.50 -1.50 x 145 in the left eye. The aim was to achieve emmetropia in both eyes. Although an examination revealed exophoria at near and distance during the 6 months following refractive surgery, the tropic aspect of the divergent deviation appeared in the right eye following the myopic regression. Laser in situ keratomileusis is an effective option to achieve binocular visual quality in myopic anisometropic patients. However, myopic regression after LASIK may disrupt the binocular visual quality.
