Asthma and Chronic obstructive pulmonary disease (COPD ) both are a common public health problem that affects a large portion of population. Nearly 20% of patients with obstructive lung disease have features of both asthma and COPD called ACOS that GOLD_GINA guidelines defines as persistent airflow limitation with several features of asthma and several features of COPD. Yet there is a little data available about diagnosis and treatment of this entity and current study aimed to compare therapeutic response between asthma, COPD and Asthma-COPD overlap syndrome (ACOS) subjects through spirometric data. In the present cross-sectional study, 30 known patients with mild to moderate asthma, 30 known patients with mild to moderate COPD and 30 known patients with mild to moderate ACOS according to GOLD_GINA guidelines were enrolled. We assessed post bronchodilator the ratio of the forced expiratory volume in the first one second to the forced vital capacity of the lungs (fev1) and the forced expiratory volume in the first one second to the forced vital capacity of the lungs (fev1/fvc) in all patients. Then they took standard treatment for 2 months and after this period spirometry was repeated. Spirometric data's changes was compared between the three groups by SPSS26 statistical software. Fev1 changes in response to treatment did not differ significantly between three groups (p > 0.05) but fev1/fvc changes differed significantly and this parameter in asthma was more than ACOS and in COPD was least. (In asthma, spirometric symbolized therapeutic response is more significant than ACOS, and in ACOS, it is more important than COPD in terms of fev1/fvc changes) and there was not any difference between the three groups regarding to FEV1 changes.
Pterygium is a bulbar conjunctival fibrovascular growth that crosses the limbus and extends onto the peripheral cornea, and in some cases leads to significant visual complications. The prevalence of this disease has been reported to be from 1.2% to about 40% in different parts of the world. Although there are various risk factors for pterygium, which include ultraviolet (UV) radiation, viral infection, hereditary factors, immune factors, aseptic inflammation, and environmental irritation, the pathogenesis of pterygium is mainly related to exposure to UV light. In addition to cosmetic problems, pterygium can lead to eye irritation, disrupt the transparency of cornea on the pupil area, and cause disorders such as corneal astigmatism and damage to the visual axis leading to vision impairment. In the last few years, the treatment of pterygium has been developed and various new solutions have been used. Surgery is the main treatment for pterygium. Various techniques such as Bare Sclera, Rotational Conjunctival Flap, Limbal Conjunctival Autograft, Amniotic Membrane Graft, and Free Conjunctival Autograft are used for the removal of pterygium. It also seems that the worrisome problem of recurrence has been significantly reduced with newer treatment methods. On the contrary, the use of auxiliary treatments such as mitomycin C, b-radiation, 5-fluorouracil, topical use of interferons, and Avastin are also effective in reducing the recurrence rate.
The incidence of diabetes increased significantly around the world in accordance with lifestyle and change in eating behaviour. Streptozotocin-Nicotinamide (STZ-NA) is capable of inducing Diabetes Mellitus type 2 in experimental animals for insulin resistance. In this research, we inspect the therapeutic potential of Etlingera elatior ethanol extract (EEEE) on diabetes associated with diabetic nephropathy and hypertension complications in mice models. Diabetes and hypertension are induced in mice using STZ 45 mg/kgBB and NA 110 mg/kgBB, followed by unilateral ureter ligation (UUO) for 4 weeks after a week of STZ-NA induction. The EEEE solution was given in the last 4 weeks with doses of 200, 400, 600, and 800 mg/kgBB. The results of this study prove the effect of vanillic acid on improving systolic blood pressure, plasma creatinine, plasma glucose, albuminuria and reducing the inflammatory marker high sensitivity C-reactive protein (hs-CRP). Histopathology of kidney is under investigation for being part of diabetes hypertension pathology. Treatment using EEEE 600 and 800 mg/kgBB for 4 weeks in experimental mice results in the decrease of plasma glucose, systolic blood pressure, plasma creatinine, albuminuria, and hs-CRP, including the restoration of kidney histology significantly compared to 200 and 400 mg/kgBB doses. This result concludes that EEEE offers modulation effects on diabetes hypertension control by reducing blood glucose rate, blood pressure rate, kidney defect, and inflammation markers.
The incidence of cisplatin-derived hyponatremia remains unknown, although nausea, vomiting, and renal dysfunction are common adverse events of cisplatin, a platinum-based preparation. The factor contributing to hyponatremia is described but not well known. This study aimed to retrospectively investigate the incidence of hyponatremia, timing, and associated risk factors. This study surveyed patients with lung cancer who received cisplatin chemotherapy from August 2013 to July 2019 at Shizuoka Cancer Center. The severity of hyponatremia was evaluated based on Common Terminology Criteria for Adverse Events. A total of 814 patients were included in this study. 682 (83.7%) patients had hyponatremia of any grade: grade 1 (<135-130 mmol/L), grade 3 (<130-120 mmol/L), and grade 4 (<120 mmol/L) hyponatremia were observed in 619 (76.0%), 51 (6.3%), and 12 (1.5%) patients, respectively. Of 63 patients with grade 3-4 hyponatremia, 43 (68.3%) developed it in the first treatment cycle. In multivariate analysis, the short hydration regimen (<3000 mL/day) has a lower incidence of grade 3-4 hyponatremia than a normal (>3000 mL) hydration regimen (OR: 0.35 [0.16-0.80], p = 0.013). In addition, if the Na+ value before the start of administration is < 135mmol/L, the incidence of grade3 and 4 hyponatremia is higher (OR:0.14 [0.07-0.28], p < 0.001). Hyponatremia due to cisplatin is likely to occur in patients with low Na levels before administration, such as the elderly. Since short hydration might avoid diuretics, hydration methods might need to be reconsidered to prevent hyponatremia.
The aim of this research is to identify the strengths and weaknesses of organizational health in the Iraqi Central Handball Federation from the point of view of those who manage the implementation of the annual curriculum, and adopt a descriptive approach in the method of studying the case. This is based on a sample of administrators of the Iraqi Handball Federation curriculum [trainers, governors, members, president, the 138 members of the Central Federation's Administrative Authority, the President, members of the sub-federations of the sports market (2021/2022) selected deliberately by 100% and then divided into statistical analysis sample (30), reconnaissance sample (10), and application sample (98)]. The regulatory health questionnaire in its Italian version was prepared to suit the specificity of the research and the type of sample it was assigned in accordance with systematic sequential steps for its acceptance of the main measurement cad actor in this research. This was then applied to address the problem researched, and its data were processed by the system (SPSS) to make conclusions and applications that help regulatory health in support of the efforts of the Central Handball Federation to implement the annual curriculum from the point of view of those who manage its implementation, and help activate the role of sponsors to manage the implementation of the annual curriculum in the Central Handball Federation effectively, and was then applied to address the research problem. It has complementary factors that need to be available at a high level in the Central Handball Federation to help manage the implementation of the annual curriculum in full, and its specificity in managing the implementation of the annual curriculum in the Central Handball Federation requires comprehensiveness and the need for its elements to achieve a high level of it. It is necessary to support them in the formation of the Central Handball Federation to further activate the role of the worlds and determine their role and avoid feeling the loss of efforts, a careful and periodic review of the level of organizational health must be conducted before planning the annual curriculum in the Central Handball Federation, modifying the paths of weakness, supporting its strengths and taking into account its suitability in order to achieve the goals when implemented later.
The force in the pencak silat jejag kick is called the moment of force or torque. The force moment is a measure of the force that can cause an object to rotate around the axis where the axis of rotation is located at the knee joint with the length of the calf as the length of the arm (the radius of the rotation axis). This research was conducted using laboratory biomechanical analysis. The research sample consisted of three male athletes of pencak silat. Previously, anthropometric measurements were carried out in the form of measuring calf length and calf muscle mass, then taking videos of athletes doing jejag kick movements in a static state with targets, which were then analyzed by kinovea. Research results showed that the technique of the jejag kick pencak silat produces a force called the moment of force or torque. Sample 1 produces a force moment of -12.00 Nm, sample 2 produces -5.53 Nm, and sample 3 produces -8.73 (negative sign means the direction of the pencak silat jejag kick is counterclockwise). The magnitude of the force moment is influenced by the angle of knee extension and the radius of the rotation axis. The amount of force moment affects the kick speed. In the speed of a movement, there is a tendency to keep moving, which is called the moment of inertia. The fasterthe movement, the greater the moment of inertia. The result is a force moment, influenced by the rotational kinetic energy that is owned and requires effort. Every effort is made to produce a force moment; it takes power to drive the effort. This means that the greater the angle of extension and the longer the calf, the greater the force moment, the faster the kick speed, and the greater the moment of inertia. This requires a large amount of rotational kinetic energy, effort, and power.
Chronic renal failure is a deficiency and failure in the excretory function of the kidneys, which causes a general imbalance in the body by retaining and accumulating nitrogenous waste and harmful substances as a result of metabolic reactions. Other functions of the kidneys, such as the regulation of fluids and electrolytes, may also be affected. This study's primary purpose is to estimate some parameters in the serum of chronic renal failure patients. Data and blood samples were obtained from 90 patients with chronic renal failure and 50 healthy volunteers for this cross-sectional study, conducted between 11 April and 26 July 2022. The results of this study show a considerable rise in the level of renin enzyme in patients (4.824±0.045) compared to the control (2.86±0.39), a high level of ALT in patients (19.56±8.13) compared to the control (11.24±0.98), high level of ALP in patients (95.34±67.71) compared to the control (38.81±5.14), high level of AST in patients (25.33±8.63) compared to the control (11.58±0.94), low level of albumin in patients with chronic renal failure (3.12±0.44) compared to the control (3.90±0.49), high level of globulin in patients with chronic renal failure (8.34±0.68) compared to the control (3.01±0.41), low level of calcium in patients with chronic renal failure (1.731±0.053) compared to the control (2.510±0.063), high level of potassium in the serum of patients with chronic renal failure (6.256±0.068) compared to the control (4.513±0.22), low level of sodium in patients with chronic renal failure (119.82±2.15) compared to the control group (143.76±2.11). According to this study, all physiological systems are significantly impacted by chronic renal failure. According to the results, chronic renal failure affects several electrolytes and liver function tests and causes a considerable increase in renin levels.
