Nutritional and Functional Assessment of Hospitalized Elderly: Impact of Sociodemographic Variables
Emam M. M. Esmayel,Mohsen M. Eldarawy,Mohamed M. M. Hassan,Hassan Mahmoud Hassanin,Walid M. Reda Ashour,Wael Mahmoud
Journal of Aging Research , 2013, DOI: 10.1155/2013/101725
Abstract: Background. This work was constructed in order to assess the nutritional and functional status in hospitalized elderly and to study the associations between them and sociodemographic variables. Methods. 200 elderly patients (>65 years old) admitted to Internal Medicine and Neurology Departments in nonemergency conditions were included. Comprehensive geriatric assessments, including nutritional and functional assessments, were done according to nutritional checklist and Barthel index, respectively. Information was gathered from the patients, from the ward nurse responsible for the patient, and from family members who were reviewed. Results. According to the nutritional checklist, 56% of participants were at high risk, 18% were at moderate risk of malnutrition, and 26% had good nutrition. There was a high nutritional risk in patients with low income and good nutrition in patients with moderate income. Also, there was a high nutritional risk in rural residents (61.9%) in comparison with urban residents (25%). Barthel index score was significantly lower in those at high risk of malnutrition compared to those at moderate risk and those with good nutrition. Conclusions. Hospitalized elderly are exposed to malnutrition, and malnourished hospitalized patients are candidates for functional impairment. Significant associations are noticed between both nutritional and functional status and specific sociodemographic variables. 1. Introduction In recent years, there has been a sharp increase in the number of older persons worldwide [1]. It is estimated that almost half of the adults who are hospitalized are 65 years of age or older, although those older than 65 years represent only 12.5 percent of the population [2]. Aging is associated with various physiological changes and needs, which make elderly people vulnerable to malnutrition [3]. Malnutrition is a major geriatric problem associated with poor health status and high mortality, and the impact of a patient’s nutritional condition on the clinical outcome has been widely recognized [4]. Application of nutritional support based on nutritional screening results significantly reduced the incidence of complications and the length of hospital stay [5]. The prevalence of malnutrition varies considerably depending on the population studied and the criteria used for the diagnosis [3]. The nutritional screening checklist (NCL) is the most frequently used nutritional screening tool for community-dwelling older adults. It is intended to prevent impairment by identifying and treating nutritional problems before they become a
Carotid Artery Prolapse and Myringocarotidopexy in Osteogenesis Imperfecta  [PDF]
Hassanin Abdulkarim, Hassan Haidar, Ahmad Abualsoud, Ahmed Elsotouhy, A. Salam Alqahtani
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.44049
Abstract: Osteogenesis Imperfecta is a rare genetic disorder of connective tissue that is caused by an error in collagen formation. The disease is characterized by abnormal bone fragility, osteopenia, blue discoloration of the sclerae and hearing loss. Chronic non-suppurative otitis media is frequent in Osteogenesis Imperfecta patients and usually attributed to Eustachian tube dysfunction due to cranial molding and deformities. In some cases of severe Osteogenesis Imperfecta, the fragile bone of the petrous carotid canal can be broken down by the pulsations of the carotid artery, this may result in prolapse of the carotid artery into the protympanum with resultant Eustachian tube obstruction and tympanic membrane retraction with adhesion to prolapsed carotid artery, a condition called myringocarotidopexy.

Journal of Cancer Therapy (JCT) , 2017, DOI: 10.4236/jct.2017.810078
Abstract: Purpose: To test the use of Intensity Modulated Radiotherapy (IMRT) to spare the bone marrow (BM) in patients treated with cancer cervix through using the bone marrow an organ at risk. Patients and methods: Thirteen patients with stage (IB2-IIIB) intact cervix cancer were included; C-T simulation was done with contrast and full bladder with slice thickness 2.5 mm. Clinical Target Volume (CTV) included the cervix, uterus, upper half of the vagina, parametrium and regional lymph nodes. The CTV was expanded by 1 cm to form the Planning Target Volume (PTV). The organ at risk (OAR) included the bladder and rectum, the external contour of the pelvic bones to define the Pelvic Bone Marrow (PBM). Four plans were done for every patient with anteroposterior-posteroanterior (AP/PA), three dimensional conformal radiotherapy (3DCRT), IMRT, bone marrow-sparing intensity-modulated pelvic radiotherapy (BMS-IMRT). Results: BMS-IMRT reduced the V20, V30, V40 and V45 of the BM in comparison to 3DCRT and IMRT plans. Reduction in V20 with BMS-IMRT plan compared to 3DCRT (p < 0.03). The PBM volume receiving 5, 10 and 20 Gy was lower AP/PA than BMS-IMRT (p < 0.01, p < 0.001 and p < 0.04 respectively). The volumes of the rectum
Self-Tuning Control for MIMO Network Systems  [PDF]
Magdi S. Mahmoud, Matasm M. Hassan Hamid
Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.32020
Abstract: The advances in MIMO systems and networking technologies introduced a revolution in recent times, especially in wireless and wired multi-cast (multi-point-to-multi-point) transmission field. In this work, the distributed versions of self-tuning proportional integral plus derivative (SPID) controller and self-tuning proportional plus integral (SPI) controller are described. An explicit rate feedback mechanism is used to design a controller for regulating the source rates in wireless and wired multi-cast networks. The control parameters of the SPID and SPI controllers are determined to ensure the stability of the control loop. Simulations are carried out with wireless and wired multi-cast models, to evaluate the performance of the SPID and SPI controllers and the ensuing results show that SPID scheme yields better performance than SPI scheme; however, it requires more computing time and central processing unit (CPU) resources.

Mahmoud Fathy Hassan, Osama El-Tohamy
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.41007

Background: Cesarean delivery has become the most common major surgical procedure in many parts of the world. Induction of labor in women with prior cesarean delivery is an alternative to mitigate the rising cesarean rates. Objectives: To compare the VBAC success rate between two vaginal forms of dinoprostone for labor induction in women with prior cesarean section. Material and Methods: A pilot study was conducted at a large Governmental Hospital, Dhahran, Saudi Arabia, including 200 women with prior cesarean section and planned for labor induction. Participants were randomly allocated into two groups. Group A (n = 100) received dinoprostone 1.5 mg vaginal tablet. Group B (n = 100) received 10 mg dinoprostone sustained release vaginal pessary. Primary outcome was vaginal delivery rate. Secondary outcomes included maternal and neonatal outcomes. Results: The dinoprostone vaginal tablet and dinoprostone vaginal pessary had a comparable vaginal delivery rate (67% and 64%, respectively; p = 0.78). The median patient satisfaction with the birth process was superior in the dinoprostone vaginal pessary group (p = 0.04). Maternal and neonatal outcomes were similar in both groups. Conclusion: Both forms of dinoprostone were effective methods for labor induction in women with prior cesarean section. However, the patient satisfaction with the birth process was in favor of the dinoprostone sustained release vaginal pessary.

Moawad Mahmoud,Hassan Walid
Annals of Saudi Medicine , 2005,
Abstract: The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation on and Treatment of High Blood Pressure (JNCVII) had new key messages that need to be highlighted for practicing physicians. More than two years has elapsed since its publication and several important trials and meta-analyses were published during this period. Most of these publications supported and reinforced the JNC-VII recommendations, but others did not fully agree. Thus, some questions have arisen that need to be addressed in future research. This review will discuss what is new in JNC-VII and post-JNC-VII evidence that supports or disputes the recommendations. In addition, the results of other significant trials will be addressed. Finally, we outline the clinical "bottom line" and emphasize the practical application of this evidence.

Open Journal of Animal Sciences (OJAS) , 2013, DOI: 10.4236/ojas.2013.31009
Abstract: The aim of the study to monitor post partal uterine involution, ovarian activity and biochemical parameters and it is relation to the subsequent fertility. A total sixty normal calving pluriparous buffaloes were examined between 14th and 75th day post partum (p.p.) rectaly, ultrasonically and blood sampling were collected on weekly sessions. There were differences (P < 0.01) between pregnant (PREG) and non-pregnant (NPREG) groups in Body condition score (BCS) and body weights. There was a difference between previous gravid uterine horn (PGUH) and non-gravid uterine horn (NPGUH) diameter in PREG and NPREG groups at 28th day p.p. The calving to first service interval in the PREG group was shorter (P = 0.03) than that of NPREG one. The number of buffaloes with dominant follicles (DF 3 8 mmdiameter) in ipsilateral and contralateral ovary to the PGUH in PREG group was higher (P < 0.01) than in NPREG. The calving to first service interval in the PREG group having DF in the ovary ipsilateral to the PGUH (n = 16) was shorter (P < 0.01) than those buffaloes having no DF (n = 18). The number of service per conception and days open in the PREG buffaloes which had no DF in the ovary ipsilateral to the PGUH were higher and longer (P < 0.01) than that which had DF group. The values of glucose and triglyceride were higher (P = 0.057) in PREG than NPREG group. In conclusion, postpartum ovarian activity has positive effect on the uterine involution and postpartum profile of some metabolities may be a good predictor of fertility status of buffaloes.

Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.43028

Objective: To compare the long term efficacy of transobturator Tape (TOT) with tension free vaginal tape (TVT) at 24 months postoperatively. Patients & Methods: 160 women with stress urinary incontinence (SUI) were randomly allocated to either TVT or TOT procedures and reviewed at 24 months after surgery. The primary outcomes were objective cure (a negative cough stress test, and a negative 1-hour pad test), and subjective cure (defined as “very much better” or “much better” improvement in the Patient Global Impression of Improvement scale). The secondary outcomes included incontinence related quality of life (using Urogenital Distress Inventory Questionnaire, and Incontinence Impact Questionnaire), and complications. Results: No statistical difference was reported in objective and subjective cure rates between both groups. Objective cure rate was 85.6% and 81.6% in the TOT and TVT groups respectively (P = 0.55). Subjective cure rate in the TOT and TVT groups were 87% and 83% respectively (P = 0.68). There were no significant differences in postoperative complications and incontinence related quality of life. However, the operating time was significantly shorter in the TOT group compared with the TVT group (22.6 ± 3.9, 27.1 ± 3; respectively, P < 0.001). Conclusion: TOT and TVT procedures were equally efficient and safe for treatment of SUI, with maintenance of high objective and subjective cure rates for 24 months. Longer follow-up is

Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.610096
Abstract: The objective was to create an Egyptian database on the contributors of fruit and vegetables in the diets of preschool children and to estimate the usual daily intakes of fruits, vegetables and vitamin C. A total of 59 healthy boys and girls aged 2.5 - 6 years attending day care centers in urban Giza governorate completed the study by interviewing their mothers on 6x non-consecutive days using the 24 h dietary recall. Participants were classified according to age, gender and socioeconomic class. Prevalence of daily consumptions of fruits and vegetables amounted to 22% and 54%, respectively of the total children. The daily intakes of fruits and vegetables averaged 117.5 and 56.4 g, respectively. The consumption of different types of fruits and vegetables was unevenly distributed by different personal and social variables. Estimated daily vitamin C supply from the diet was 38 mg per child, which satisfied the respective recommended nutrient intake (RNI) of 30 mg for the first six years of life. However, the diet of 15% of the children covered less than 75% of RNI. Top fruits contributing to vitamin C were oranges, guava, watermelon, pears and grapes. Extra foods such as chipsy was consumed by 81% of the children, contributed 18% to daily vitamin C supply and also 58.6 mg sodium. A multilevel intervention strategy is warranted for promoting daily fruit and vegetable intake and healthy eating in early childhood.
