Physician and Patient Perspective to Weight Gain in Pregnancy

Gaining weight outside of the Institute of Medicine guidelines puts a woman and her foetus at an increased risk. Limited or incorrect information is being provided to women during antenatal care. Research shows that physicians do not perceive this as an important issue. We aimed to assess both physician and patient perspective to weight gain in pregnancy as well as assessing physicians current practice to weight management. 71% of women want to be given a target weight to gain during pregnancy; 87% want to be told if they are gaining an inappropriate amount of weight. 87.5% of physicians believe that weight management is important; 31.2% advise patients about weight gain.

Treatment of Cerebral Mucormycosis with Prolonged Liposomal Amphotericin B (>1000 days)

Mucormycosis is a rare but invasive and potentially lethal infection caused by ubiquitous fungi of the order Mucorales. The primary mode of infection is inhalation of fungal spores. Rhinocerebral and pulmonary infections are most common, however, other organ systems including the central nervous system can be affected, presumably by occult fungemia. We describe the prolonged treatment course (>1000 days) of a patient with cerebral mucormycosis using liposomal amphotericin B (LAMB). Two different attempts were made to replace LAMB with posaconazole, but each occasion resulted in therapeutic failure. This case represents the longest course of LAMB reported in the literature.

Upper Oesophageal Foreign Body with Acute Drooling in a Child with Congenital Hypotonia

Foreign body ingestion and aspiration commonly affect children. The most vulnerable age is early childhood when children tend to explore new objects with their mouths or by an accident by elder siblings. A 2-year-old female child who is known to have congenital hypotonia, status post laparoscopic fundoplication and gastrostomy tube feeding (G- tube) inserted at age one year. Then she was in stable condition till when presented with acute unexplained drooling of frothy whitish secretions, mild cough and difficulty breathing with hypoxemia. X-ray chest and upper abdomen revealed normal. She underwent flexible bronchoscopy revealed normal and then direct laryngoscopy was extracted a covering plastic of the feeding tube in the upper end cervical oesophagus by Magill forceps technique.

Perceived Barriers to Maintaining Healthy Body Weight among Saudi Women of Reproductive Age in Jeddah City

Maintaining a healthy body weight is important for overall health and can help prevent and control many chronic conditions. However, the information surrounding the barriers to healthy eating (HE) and physical activity (PA) for weight maintenance among Saudi women of reproductive age is insufficient to design and develop intervention programs. To explore personal, social, and physical environmental factors that act as barriers to maintaining a healthy weight and how these barriers vary by socio-demographic and weight status. A cross-sectional study was conducted in 2014 using a stratified two-stage cluster sampling design comprising 408 Saudi women attending 12 Jeddah Primary Health Centers (JPHCCs). Data was collected using a structured questionnaire consisting of socio-demographic factors, eating habits (EHs), PA, and perceived barriers to a maintenance of healthy weight maintenance.

Macrocystis of the Lung in a Preterm Neonate: Case Report

Thoracic ultrasonography has been used to evaluate pulmonary parenchyma and the macrocystis of the lung in a preterm with congenital cystic adenomatoid malformation type I. The images gained have been important for diagnosis and therapeutic strategies in our case. An infant was prematurely born with congenital cystic adenomatoid malformation type I. The chest X-ray and computerized tomography showed a great opaque area in the entire right lung, we considered performing a pneumonectomy. This opaque area hampered the expansion of left lung. After draining the macrocystis by ultrasonography-guided puncture, it was possible considering and performing the lobectomy due to the reduction of the volume of macrocystis. During follow up at 4 months, the infant did not show complications and the chest X-ray revealed the reduction of volume of the dense area in parenchyma of right lung.

Effects of Mutual Interaction between Constituent Elements on Phase Formation of High Entropy Alloys

High entropy alloys (HEAs) are alloys that contains multiple elements, often five or more principal elements in equiatomic or near equiatomic ratio with or without minor elements. As felt from the name, high mixing entropy is the sole parameter to decide the solid solution alloy formation in HEAs but, the mutual interaction between elements are key parameters to predict the phase formation in HEAs as proposed by some researchers. In this review the guideline for alloy design in HEAs for the formation of solid solution phases are proposed on basis of atomic size difference (δ), mixing entropy (ΔSmix), mixing enthalpy (ΔHmix), valence electron concentration (VEC) and electronegativity difference (Δχ).

The Effects of the Film Thickness and Roughness in the Anodization Process of Very Thin Aluminum Films

The anodization of aluminum foils having micrometer thickness is a common process and results in hexagonally self-ordered alumina membranes. However, anodic aluminum oxide (AAO) membranes fabricated from nanometer-thin films present new challenges to the anodization process, since aluminum films adheres poorly on supporting substrates and the smoothness of the film is highly related to the kind of substrate.
