Longitudinal study of 157 children from 14-18 weeks of gestation to 5 years after delivery to find out relationship between weight gain during pregnancy and birth weight with IQ index of children 5 years of old. Raven's test (Progressive Matrices) was used to evaluate mental development of child. The results showed that: there was positive correlation between birth weight and IQ index. The children with lower birth weight will have IQ index lower after 5 years delivery. In addition to, the results of study showed that: weight gain during pregnancy had strong positive correlation with birth weight

After reviewing studies on weight cycling, we concluded that methodology left much to be desired and that the following matlers should be taken into reconsideration :1. There is as yet no established definition of the term “weight cycling”. Consequently, different definitions of weight cycling are used in different studies.2. The definition of weight cycling lacks any standard. Consequently, different criteria of weight change are used in different studies.3. Weight cycling is assessed by cycles of loss and regain of body weight. For the purpose of elucidating the correlation between weight cycling and health body weight is preferable to BMI as a weight change variable.4. Providing a relevant measure for weight cycling encompasses many components. The body weight collected by direct measurement is most reliable. However, an interval of measurement of body weight differs in different studies.5. In light of the standards of population-based epidemiological research, the studies are generally of small-to-modest size.6. Few studies have been able to differentiate between intentional and unintentional weight changes.

Introduction: The demanding nature of medical school causes students to experience stress, anxiety, and depressive episodes that may cause students to gain or lose weight. This study aimed to determine the association of weight changes and stress levels among a private medical school students. Methods: Data were collected two times with an interval of 30 days through on-site measurement of the students’ anthropometrics using a stadiometer and utilization of online survey questionnaires accessed via QR code. Demographics and disease states were identified in the first round of data collection while the Perceived Stress Scale-10 (PSS-10) and identification of stressors was integrated in the second round of data collection. Results: Among the 212 individuals, 69.8% were categorized into having perceived moderate stress levels, 22.2% with high stress, and 8% with low stress. Of the 212 cases, 86 gained weight, 91 lost weight, and 35 had no change in weight. Fear of failure, poor motivation, and difficulty understanding lectures are among the top overall stressors. The study noted that there is a moderate association between stress and weight changes but it is not enough to reach statistical significance (0.161), as the sample size was not reached. The study revealed that the prevailing diseases were Polycystic Ovarian Syndrome, Hypothyroidism, and Hypertension, which have varying degrees of impact on weight change. Conclusion There is an association between weight changes and stress levels among first to fourth year medical students of a private medical school from A.Y. 2023-2024.

OBJECTIVE: Rod-screw fixation systems are widely used for spinal instrumentation. Although many biomechanical studies on rod-screw systems have been carried out, but the effects of rod contouring on the construct strength is still not very well defined in the literature. This work examines the mechanical impact of straight, 20° kyphotic, and 20° lordotic rod contouring on rod-screw fixation systems, by forming a corpectomy model. METHODS: The corpectomy groups were prepared using ultra-high molecular weight polyethylene samples. Non-destructive loads were applied during flexion/extension and torsion testing. Spine-loading conditions were simulated by load subjections of 100 N with a velocity of 5 mm min⁻¹, to ensure 8.4-Nm moment. For torsional loading, the corpectomy models were subjected to rotational displacement of 0.5° s⁻¹ to an end point of 5.0°, in a torsion testing machine. RESULTS: Under both flexion and extension loading conditions the stiffness values for the lordotic rod-screw system were the highest. Under torsional loading conditions, the lordotic rod-screw system exhibited the highest torsional rigidity. CONCLUSION: We concluded that the lordotic rod-screw system was the most rigid among the systems tested and the risk of rod and screw failure is much higher in the kyphotic rod-screw systems. Further biomechanical studies should be attempted to compare between different rod kyphotic angles to minimize the kyphotic rod failure rate and to offer a more stable and rigid rod-screw construct models for surgical application in the kyphotic vertebrae.

In the year 2002 at the central hospital of Obstetrics and Gynecoligy. The number of newborn babies of > 4000g accounted for 2,6% of all obstetric cases, among them the male number was 1,9 fold higher than the female and the multiparum delivering cases was 1,7 folds higher than the monoparum. In delivering heavy babies > 4000g, Caesarian section was the method of large choice (78,5%) but in normal delivery, complication is the most common (70,6%) and hypoglycemia is the complication of highest frequency (78,3%)
