ENHANCING DISSOLUTION RATE OF INDOMETHACIN BY IN SITU CRYSTALIZATION; DEVELOPMENT OF ORALLY DISINTEGRATING TABLETS

Objective: The main objective of this study was to investigate the potential of in situ crystallization of indomethacin, in presence or absence of hydrophilic materials, to improve drug dissolution with the goal of developing fast disintegrating tablets.Methods: Indomethacin crystals were prepared by bottom up approach. Water containing hydrophilic additive (polymer or/and surfactant) was added to ethanolic solution of indomethacin while stirring. The selected polymers were hydroxylpropylmethyl cellulose E5 (HPMC E5), polyethylene glycol 6000 (PEG6000) and polyvinylpyrrolidone K40 (PVP K40). The surfactants used were Tween80 and Glucire 44/14. The precipitated particles were collected and air dried. Solid state characterization were performed in addition to in vitro release studies in both acidic (0.1 N HCL) and alkaline medium (phosphate buffer pH 6.8). Optimized formulation was selected to develop fast disintegrating tablets.Results: Thermal behavior suggested modulation in crystalline nature with reduction in particle size that was confirmed by X-ray diffraction results. Infrared spectroscopy excluded any interaction between drug and hydrophilic excipients. Drug dissolution in acid media showed slight improve in drug release, while marked increase was observed in the alkaline media. Combination between Tween80 and HPMC (F7) showed the best dissolution parameters with 5-folds enhancement in release efficiency (RE) compared to pure drug. Formula F7 was successively used to formulate fast disintegrating tablets with prompted release of 58% of the loaded dose and RE of 83%.Conclusion: In situ crystallization of indomethacin is a good approach for enhanced dissolution rate with the presence of hydrophilic additives during precipitation process improving the efficiency

Faktor Risiko Kematian Neonatal Dini di Rumah Sakit Bersalin

Infant mortality rate in Indonesia is still high. Fifty percent of the neonatal mortality occurred among low birth weight infants (LBWI) and neonatal mortality within 7 days of life accounted for 50% of total infant mortalities. This study was aimed to examine the extent of early neonatal mortality risk by antenatal care (ANC), Tetanus Toxoid (TT) immunization status of pregnant women, anemia during pregnancy, birth weight of neonatal, parity status, and hypothermia status.This study was a case control study with direct interview to respondents, conducted in the Maternity Hospital of Makassar with 40 cases and 120 controls. Samples were selected by purposive sam- pling. Study results indicated that risk factor of early neonatal mortality were ANC (p value = 0,000; odds ratio, OR = 7,33; CI 95% = 2,966 - 18,129), TT immunization status (p value = 0,000; OR = 19,205; CI 95% = 7,902 - 46,678), pregnancy anemia (p value = 0,000; OR = 32,818; CI 95% = 7,549 - 142,674), birth weight (p value = 0,000; OR = 122,212; CI 95% = 32,324 - 462,068), parity status (p value = 0,000; OR = 5,537; CI 95% = 2,029 - 15,111), asphyxia status (p value = 0,000; OR = 8,197; CI 95% = 0,452 - 2,745), whereas hypothermia status (p value = 0,815; OR = 1,114; 0,452 - 2,745) was not a risk factor. Results of logistic regression multivariate analysis indicated that infant\u27s birth weight was the most risk factor of early neonatal mortality (p value = 0,000). Specific surveillance program for high risk neonatal needed to be arranged in all health centers

Use of Prophylactic Inferior Vena Cava Filters in Trauma

Venous thromboembolisms, specifically pulmonary embolisms (PEs), represent a significant burden on healthcare systems worldwide, particularly within the setting of trauma. According to the literature, PEs are the most common cause of in-hospital death; however, this condition can be prevented with a variety of prophylactic and therapeutic measures. This article aimed to examine current evidence on the use, indications for prophylaxis, outcomes and complications of prophylactic inferior vena cava filters in trauma patients

Missed Gastric Injuries in Blunt Abdominal Trauma : Case report with review of literature

Hollow viscus injuries of the digestive tract are an uncommon occurrence in blunt abdominal trauma. We report a 39-year-old male who was hit by a vehicle as a pedestrian and admitted to the Sultan Qaboos University Hospital, Muscat, Oman, in 2015. He underwent an exploratory laparotomy which revealed injuries to the distal stomach, liver and descending colon. Postoperatively, the patient was febrile, tachycardic and hypotensive. Abdominal examination revealed distention and tenderness. The next day, a repeat laparotomy identified a gastric injury which had not been diagnosed during the initial laparotomy. Although the defect was repaired, the patient subsequently died as a result of multiorgan failure. Missed gastric injuries are rare and are associated with a grave prognosis, particularly for trauma patients. Delays in diagnosis, in addition to associated injuries, contribute to a high mortality rate

Numerical Study of the Behaviour of Embankment Constructed over Soft Soil Stabilized with Ordinary and Geosynthetic - Reinforced Stone Columns

Structures constructed on soft soils may undergo significant settlement, local or global instability, and a significant lateral displacement of the soft soil layer. Ordinary stone columns (OSC) and stone columns strengthened with geosynthetic reinforcement reduce settlement and improve the subsoil's bearing capacity. Numerical analyses have been performed using a 3-dimensional finite element program (PLAXIS3D) to investigate the time-dependent behavior of embankments resting on stone columns constructed in very soft clay. The geosynthetic encasement is the more typical type of reinforcement; however, laminated layers can be adopted in this study. The geosynthetics material was used to strengthen the OSC in the form of vertical encasement, horizontal stripes, and combined vertical-horizontal reinforcement and vertical-basal geogrid reinforcement (BGR). This research compares these forms of reinforcement on embankment behavior. The research results showed that using the encased stone column (ESC) and the vertical-horizontal reinforced stone columns (V-HRSC) have provided a considerable improvement in the lateral deformation of the column over its length, generation, and dissipation of excess pore pressure, and settlement. An increase in factor of safety (FOS) against failure of the embankment was observed by 53% using the ESC compared to untreated soil. Using the horizontal geosynthetic layer (HGL) and the (BGR) after encasing the stone columns has no effect on the safety factor as the failure mechanism converted from deep-seated to surface failure

Predictors of Long Covid 19 Syndrome

Background: Symptoms of covid persist in most cases with development of a multisystem syndrome called long covid syndrome.Objective: The aim of the work was to evaluate symptoms that persist after the acute stage of the disease in a cohort of patients with confirmed or suspected COVID 19 and to define the predictors for long COVID syndrome.Patients and method: This retrospective study involved 164 patients with previously confirmed or highly suspected COVID 19 and still attending to the post covid outpatient clinic in El-Minia University Chest Hospital complaining from persistence of symptoms or for regular follow up. Their data was obtained from their previous medical reports. Results: Post Covid 19 symptoms were found in about 86 % of the studied patients with 42.7% reported neuropsychiatric symptoms and 26.8% reported respiratory symptoms. The most common reported symptoms in nonsevere cases were the anxiety disorders (18.9%), followed by chronic fatigue and neuropathy (15.2%), while chronic dyspnea in 9.8% mostly in severe cases, while vertigo and headache in 9.1%, musculoskeletal symptoms in 6.1% and skin lesions in 3.7%.Conclusion: It could be concluded that persistence of symptoms is very common after acute Covid 19 infection. Chronic dyspnea was reported more frequently in severe cases while anxiety reported mostly by patients with mild disease

Interaction Analysis between Existing Loaded Piles and Braced Excavation Design Parameters

Three-dimensional numerical analyses are conducted using the finite element software PLAXIS 3D to gain insight into the interaction behavior between deep excavation and adjacent piled foundations in fully saturated sand. Effects of excavation width and depth, the distance between strut level and the excavation surface with each excavation stage, strut stiffness, diaphragm wall stiffness, and diaphragm wall depth are examined during the adjacent excavation. In practice, incorrect values of the braced excavation design parameters may result in an uneconomical or even unsafe design. The analyses revealed that increasing the excavation width or depth has a significant influence on the adjacent pile group behavior. Additionally, it is also observed that reducing the distance between the strut level and the excavation surface with each excavation stage, increasing the struts stiffness, increasing diaphragm wall thickness or depth, and reducing the horizontal or vertical span of struts can assist to reduce settlement and tilting of the pile group induced by the adjacent excavation
