In Islamic law, the concept of baligh has long been debated among clerics. The debate also appears to have resulted in different rules regarding the minimum age of marriage among Muslim countries. This paper aims to reveal the maturity standard regarding the minimum age of marriage in four Muslim countries: Egypt, Pakistan, Tunisia, and Indonesia. This paper is based on library research and employs a comparative study approach. This paper argues that Egypt, Pakistan, Tunisia, and Indonesia have a different minimum age for marriage. In Egypt and Pakistan, the minimum age for marriage is 18 years for men and 16 years for women. However, Pakistan has gone further by instituting legal sanctions if the regulation of the minimum age is violated. In Tunisia, the minimum age for marriage is 18 years for men and women, while in Indonesia it is 19 years for men and women. The determination of the minimum age for marriage is intended for several purposes, including limiting the number of early marriages, reducing the divorce rate, and preparing a strong national generation through the maturity of the marriage age. These interests, from the perspective of Islamic law, are the manifestation of the principle of maslahah (fundamentally aimed at achieving goodness and rejecting harm concerning marital life). [Dalam hukum Islam, konsep balig sudah lama diperdebatkan di kalangan ulama. Perdebatan tersebut juga tampaknya telah menghasilkan aturan yang berbeda mengenai usia minimum pernikahan di antara negara-negara Muslim. Tulisan ini bertujuan untuk mengungkapkan standar kedewasaan mengenai usia minimum menikah di empat negara Muslim: Mesir, Pakistan, Tunisia, dan Indonesia. Makalah ini didasarkan pada penelitian kepustakaan dan menggunakan pendekatan studi komparatif. Tulisan ini berpendapat bahwa Mesir, Pakistan, Tunisia, dan Indonesia memiliki perbedaan usia minimum untuk menikah. Di Mesir dan Pakistan, usia minimum untuk menikah adalah 18 tahun untuk laki-laki dan 16 tahun untuk perempuan. Namun, Pakistan telah melangkah lebih jauh dengan memberikan sanksi hukum jika peraturan usia minimum dilanggar. Di Tunisia, usia minimum untuk menikah adalah 18 tahun untuk pria dan wanita, sedangkan di Indonesia adalah 19 tahun untuk pria dan wanita. Penetapan usia minimal menikah dimaksudkan untuk beberapa tujuan, antara lain membatasi jumlah pernikahan dini, menekan angka perceraian, dan mempersiapkan generasi bangsa yang kuat melalui pendewasaan usia pernikahan. Kepentingan-kepentingan tersebut, dalam perspektif hukum Islam, merupakan manifestasi dari prinsip maslahah (menarik kebaikan dan menolak keburukan dalam kehidupan berumah tangga).]

Background: Clomiphen citrate (CC) is the first line therapy for women with infertility and poly cystic ovary syndrome( PCOS). However, 20-25% of women are resistant to CC and do not ovulate. Objective: The objective of this study was to evaluate the efficacy of sequential treatment of metformin and incremental doses of letrozole in induction of ovulation in cases of CC-resistant PCOS patients. Materials and Methods: In this prospective before-after study, we enrolled 106 anovulatory PCOS women who failed to ovulate with CC alone from Amir-Almomenin University Hospital in Semnan, Iran. After an initial 6-8 weeks of metformin treatment, they received 2.5 mg letrozole daily on days 3-7 after menes. If they did not ovulate with 2.5 mg letrozole, the doses were increased to 5 to 7.5 mg daily in subsequent cycles. The main outcomes were ovulatory rate, pregnancy rate and cumulative pregnancy rate. Results: 13.33% of patients conceived with metformin alone. Ovulation occurred in 83 out of remaining 91 patients (91.2%). 78.02% of patients responded to lower doses of letrozole. Cumulative pregnancy rate was 60/ 105 (57.14%).Conclusion: We suggest that treatment in CC-resistant PCOS patients should begin at first with lower doses of letrozole and could increase to the higher dose depending on the patient response before considering more aggressive therapeutic alternatives such as gonadotropins.

The tragic COVID-19 pandemic affected many children worldwide. Among the factors that may influence the course of viral infections including COVID-19, it is still uncertain whether atopy has a protective or predisposing role. The study aims to address the knowledge gap by investigating the prevalence and severity of COVID-19 among atopic children in Kerman, in 2022. A descriptive-analytical cross-sectional study on children with a history of atopy was performed in Kerman Medical University. Demographic information, type of atopy (including allergic rhinitis, Hyper-Reactive Airway Disease (HRAD) or asthma, eczema, urticaria, anaphylaxis, and food allergy), history of COVID-19 infection, and disease severity were recorded. A total of 1007 children and adolescents, (boys: 56.4%, girls: 43.6%, age:5.61±2.64 years) were included in the study. History of COVID-19 infection was positive in 53.5%, with 75.9% of the cases exhibiting mild disease severity. The frequency of atopies was HRAD or asthma (67.2%), allergic rhinitis (42.6%), and food allergy (27.4%). The frequency of COVID-19 cases was significantly higher among patients with HRAD or asthma, whereas it was significantly lower among those with food allergies, anaphylaxis, and eczema. Among atopic individuals, COVID-19 severity was significantly lower in those with allergic rhinitis, while the opposite trend was observed among food-allergic individuals. This study sheds light on the relationship between atopy and COVID-19 among pediatric patients. It seems specific types of atopies may influence the risk and severity of COVID-19 infection differently. A better understanding of these associations can inform clinical management and preventive measures for vulnerable pediatric populations.

Background: Cancer is a frightening disease. Therefore, the care of cancer patients is very complex. This study aimed to investigate the effect of the education based on Orem's self-care model on self-care abilities of the patients undergoing chemotherapy in Shafa Hospital in Ahvaz city, Iran., Methods: This randomized clinical trial was carried out in 2018 on 100 cancer patients undergoing chemotherapy, who referred to Shafa Hospital in Ahvaz city, Iran. The sampling method was simple and the subjects were randomly divided into two experimental and control groups (50 in the experimental and 50 in the control group). The study outcome was the self-care ability of the patients measured before and 2 months after the intervention by the control and experimental groups. The educational intervention consisted of five 60-minute sessions (one session per week) held as educational and counseling ones through group, face-to-face and individual training based on the identified needs of the patients in the experimental group at Shafa Hospital Chemotherapy Department. To collect data, two questionnaires [the assess and identify the conceptual pattern of Orem questionnaire and the Self-care capacity assessment (ESCI)]were used. Statistical data were entered into SPSS software version 20 and analyzed by chi-square, independent t-test and paired t-test., Results: The mean and standard deviation of age was 35.06 ± 14.51 in the control group and 31.72 ± 15.01 in the experimental group. The results of the independent t-test showed that before the educational intervention, there was no significant difference between the two groups in terms of the mean self-care (P = 0.38). But after the intervention, a significant difference was found between the mean self-care scores of the experimental and control groups (P = 0.001)., Conclusion: Application of Orem's self-care model led to increased self-care ability of the cancer patients undergoing chemotherapy. Therefore, it is recommended that this model be included in the routine programs of chemotherapy departments., Trial Registration: IRCT registration number: IRCT20160418027449N6.

Background: According to international guidelines and literature, all patients with intermittent claudication should receive an initial treatment of cardiovascular risk modification, lifestyle coaching, and supervised exercise therapy. In the literature, supervised exercise therapy often consists of treadmill or track walking. However, alternative modes of exercise therapy have been described and yielded similar results to walking. This raises the following question: which exercise mode produces the most favourable results? This is the first update of the original review published in 2014., Objectives: To assess the effects of alternative modes of supervised exercise therapy compared to traditional walking exercise in patients with intermittent claudication., Search Methods: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 4 March 2019. We also undertook reference checking, citation searching and contact with study authors to identify additional studies. No language restriction was applied., Selection Criteria: We included parallel-group randomised controlled trials comparing alternative modes of exercise training or combinations of exercise modes with a control group of supervised walking exercise in patients with clinically determined intermittent claudication. The supervised walking programme needed to be supervised at least twice a week for a consecutive six weeks of training., Data Collection and Analysis: Two review authors independently selected studies, extracted data, and assessed the risk of bias for each study. As we included studies with different treadmill test protocols and different measuring units (metres, minutes, or seconds), the standardised mean difference (SMD) approach was used for summary statistics of mean walking distance (MWD) and pain-free walking distance (PFWD). Summary estimates were obtained for all outcome measures using a random-effects model. We used the GRADE approach to assess the certainty of the evidence., Main Results: For this update, five additional studies were included, making a total of 10 studies that randomised a total of 527 participants with intermittent claudication (IC). The alternative modes of exercise therapy included cycling, lower-extremity resistance training, upper-arm ergometry, Nordic walking, and combinations of exercise modes. Besides randomised controlled trials, two quasi-randomised trials were included. Overall risk of bias in included studies varied from high to low. According to GRADE criteria, the certainty of the evidence was downgraded to low, due to the relatively small sample sizes, clinical inconsistency, and inclusion of three studies with risk of bias concerns. Overall, comparing alternative exercise modes versus walking showed no clear differences for MWD at 12 weeks (standardised mean difference (SMD) -0.01, 95% confidence interval (CI) -0.29 to 0.27; P = 0.95; 6 studies; 274 participants; low-certainty evidence); or at the end of training (SMD -0.11, 95% CI -0.33 to 0.11; P = 0.32; 9 studies; 412 participants; low-certainty evidence). Similarly, no clear differences were detected in PFWD at 12 weeks (SMD -0.01, 95% CI -0.26 to 0.25; P = 0.97; 5 studies; 249 participants; low-certainty evidence); or at the end of training (SMD -0.06, 95% CI -0.30 to 0.17; P = 0.59; 8 studies, 382 participants; low-certainty evidence). Four studies reported on health-related quality of life (HR-QoL) and three studies reported on functional impairment. As the studies used different measurements, meta-analysis was only possible for the walking impairment questionnaire (WIQ) distance score, which demonstrated little or no difference between groups (MD -5.52, 95% CI -17.41 to 6.36; P = 0.36; 2 studies; 96 participants; low-certainty evidence)., Authors' Conclusions: This review found no clear difference between alternative exercise modes and supervised walking exercise in improving the maximum and pain-free walking distance in patients with intermittent claudication. The certainty of this evidence was judged to be low, due to clinical inconsistency, small sample size and risk of bias concerns. The findings of this review indicate that alternative exercise modes may be useful when supervised walking exercise is not an option. More RCTs with adequate methodological quality and sufficient power are needed to provide solid evidence for comparisons between each alternative exercise mode and the current standard of supervised treadmill walking. Future RCTs should investigate outcome measures on walking behaviour, physical activity, cardiovascular risk, and HR-QoL, using standardised testing methods and reporting of outcomes to allow meaningful comparison across studies., (Copyright © 2020 The Cochrane Collaboration.

Glucose Oxidase (GOD), is a common flavoprotein from Aspergillus niger ATCC 9029 with a broad application in biotechnology, food and medical industries. In this study, GOD gene was cloned into the expression vector, pPIC9 and screened by the alcohol oxidase promoter. The enzyme production increased at 28 °C. GOD activity induced by 1.0% methanol and the highest level of GOD production was the result of shaking rate at 225 rpm. The highest enzyme activity obtained at a pH value ranged from 5 to 7 at 50 °C. The enzyme was stable at a broad pH range and temperature.

Background: Intermittent claudication (IC) is the classic symptomatic form of peripheral arterial disease affecting an estimated 4.5% of the general population aged 40 years and older. Patients with IC experience limitations in their ambulatory function resulting in functional disability and impaired quality of life (QoL). Endovascular revascularisation has been proposed as an effective treatment for patients with IC and is increasingly performed., Objectives: The main objective of this systematic review is to summarise the (added) effects of endovascular revascularisation on functional performance and QoL in the management of IC., Search Methods: For this review the Cochrane Vascular Information Specialist (CIS) searched the Specialised Register (February 2017) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 1). The CIS also searched trials registries for details of ongoing and unpublished studies., Selection Criteria: Randomised controlled trials (RCTs) comparing endovascular revascularisation (± conservative therapy consisting of supervised exercise or pharmacotherapy) versus no therapy (except advice to exercise) or versus conservative therapy (i.e. supervised exercise or pharmacotherapy) for IC., Data Collection and Analysis: Two review authors independently selected studies, extracted data, and assessed the methodological quality of studies. Given large variation in the intensity of treadmill protocols to assess walking distances and use of different instruments to assess QoL, we used standardised mean difference (SMD) as treatment effect for continuous outcome measures to allow standardisation of results and calculated the pooled SMD as treatment effect size in meta-analyses. We interpreted pooled SMDs using rules of thumb (< 0.40 = small, 0.40 to 0.70 = moderate, > 0.70 = large effect) according to the Cochrane Handbook for Systematic Reviews of Interventions. We calculated the pooled treatment effect size for dichotomous outcome measures as odds ratio (OR)., Main Results: We identified ten RCTs (1087 participants) assessing the value of endovascular revascularisation in the management of IC. These RCTs compared endovascular revascularisation versus no specific treatment for IC or conservative therapy or a combination therapy of endovascular revascularisation plus conservative therapy versus conservative therapy alone. In the included studies, conservative treatment consisted of supervised exercise or pharmacotherapy with cilostazol 100 mg twice daily. The quality of the evidence ranged from low to high and was downgraded mainly owing to substantial heterogeneity and small sample size.Comparing endovascular revascularisation versus no specific treatment for IC (except advice to exercise) showed a moderate effect on maximum walking distance (MWD) (SMD 0.70, 95% confidence interval (CI) 0.31 to 1.08; 3 studies; 125 participants; moderate-quality evidence) and a large effect on pain-free walking distance (PFWD) (SMD 1.29, 95% CI 0.90 to 1.68; 3 studies; 125 participants; moderate-quality evidence) in favour of endovascular revascularisation. Long-term follow-up in two studies (103 participants) showed no clear differences between groups for MWD (SMD 0.67, 95% CI -0.30 to 1.63; low-quality evidence) and PFWD (SMD 0.69, 95% CI -0.45 to 1.82; low-quality evidence). The number of secondary invasive interventions (OR 0.81, 95% CI 0.12 to 5.28; 2 studies; 118 participants; moderate-quality evidence) was also not different between groups. One study reported no differences in disease-specific QoL after two years.Data from five studies (n = 345) comparing endovascular revascularisation versus supervised exercise showed no clear differences between groups for MWD (SMD -0.42, 95% CI -0.87 to 0.04; moderate-quality evidence) and PFWD (SMD -0.05, 95% CI -0.38 to 0.29; moderate-quality evidence). Similarliy, long-term follow-up in three studies (184 participants) revealed no differences between groups for MWD (SMD -0.02, 95% CI -0.36 to 0.32; moderate-quality evidence) and PFWD (SMD 0.11, 95% CI -0.26 to 0.48; moderate-quality evidence). In addition, high-quality evidence showed no difference between groups in the number of secondary invasive interventions (OR 1.40, 95% CI 0.70 to 2.80; 4 studies; 395 participants) and in disease-specific QoL (SMD 0.18, 95% CI -0.04 to 0.41; 3 studies; 301 participants).Comparing endovascular revascularisation plus supervised exercise versus supervised exercise alone showed no clear differences between groups for MWD (SMD 0.26, 95% CI -0.13 to 0.64; 3 studies; 432 participants; moderate-quality evidence) and PFWD (SMD 0.33, 95% CI -0.26 to 0.93; 2 studies; 305 participants; moderate-quality evidence). Long-term follow-up in one study (106 participants) revealed a large effect on MWD (SMD 1.18, 95% CI 0.65 to 1.70; low-quality evidence) in favour of the combination therapy. Reports indicate that disease-specific QoL was comparable between groups (SMD 0.25, 95% CI -0.05 to 0.56; 2 studies; 330 participants; moderate-quality evidence) and that the number of secondary invasive interventions (OR 0.27, 95% CI 0.13 to 0.55; 3 studies; 457 participants; high-quality evidence) was lower following combination therapy.Two studies comparing endovascular revascularisation plus pharmacotherapy (cilostazol) versus pharmacotherapy alone provided data showing a small effect on MWD (SMD 0.38, 95% CI 0.08 to 0.68; 186 participants; high-quality evidence), a moderate effect on PFWD (SMD 0.63, 95% CI 0.33 to 0.94; 186 participants; high-quality evidence), and a moderate effect on disease-specific QoL (SMD 0.59, 95% CI 0.27 to 0.91; 170 participants; high-quality evidence) in favour of combination therapy. Long-term follow-up in one study (47 participants) revealed a moderate effect on MWD (SMD 0.72, 95% CI 0.09 to 1.36; P = 0.02) in favour of combination therapy and no clear differences in PFWD between groups (SMD 0.54, 95% CI -0.08 to 1.17; P = 0.09). The number of secondary invasive interventions was comparable between groups (OR 1.83, 95% CI 0.49 to 6.83; 199 participants; high-quality evidence)., Authors' Conclusions: In the management of patients with IC, endovascular revascularisation does not provide significant benefits compared with supervised exercise alone in terms of improvement in functional performance or QoL. Although the number of studies is small and clinical heterogeneity underlines the need for more homogenous and larger studies, evidence suggests that a synergetic effect may occur when endovascular revascularisation is combined with a conservative therapy of supervised exercise or pharmacotherapy with cilostazol: the combination therapy seems to result in greater improvements in functional performance and in QoL scores than are seen with conservative therapy alone.

Background: According to international guidelines and literature, all patients with intermittent claudication should receive an initial treatment of cardiovascular risk modification, lifestyle coaching, and supervised exercise therapy. In most studies, supervised exercise therapy consists of treadmill or track walking. However, alternative modes of exercise therapy have been described and yielded similar results to walking. Therefore, the following question remains: Which exercise mode gives the most beneficial results?, Primary Objective: To assess the effects of different modes of supervised exercise therapy on the maximum walking distance (MWD) of patients with intermittent claudication., Secondary Objectives: To assess the effects of different modes of supervised exercise therapy on pain-free walking distance (PFWD) and health-related quality of life scores (HR-QoL) of patients with intermittent claudication., Search Methods: The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Cochrane Peripheral Vascular Diseases Group Specialised Register (July 2013); CENTRAL (2013, Issue 6), in The Cochrane Lib rary; and clinical trials databases. The authors searched the MEDLINE (1946 to July 2013) and Embase (1973 to July 2013) databases and reviewed the reference lists of identified articles to detect other relevant citations., Selection Criteria: Randomised controlled trials of studies comparing alternative modes of exercise training or combinations of exercise modes with a control group of supervised walking exercise in patients with clinically determined intermittent claudication. The supervised walking programme needed to be supervised at least twice a week for a consecutive six weeks of training., Data Collection and Analysis: Two authors independently selected studies, extracted data, and assessed the risk of bias for each study. Because of different treadmill test protocols to assess the maximum or pain-free walking distance, we converted all distances or walking times to total metabolic equivalents (METs) using the American College of Sports Medicine (ACSM) walking equation., Main Results: In this review, we included a total of five studies comparing supervised walking exercise and alternative modes of exercise. The alternative modes of exercise therapy included cycling, strength training, and upper-arm ergometry. The studies represented a sample size of 135 participants with a low risk of bias. Overall, there was no clear evidence of a difference between supervised walking exercise and alternative modes of exercise in maximum walking distance (8.15 METs, 95% confidence interval (CI) -2.63 to 18.94, P = 0.14, equivalent of an increase of 173 metres, 95% CI -56 to 401) on a treadmill with no incline and an average speed of 3.2 km/h, which is comparable with walking in daily life.Similarly, there was no clear evidence of a difference between supervised walking exercise and alternative modes of exercise in pain-free walking distance (6.42 METs, 95% CI -1.52 to 14.36, P = 0.11, equivalent of an increase of 136 metres, 95% CI -32 to 304). Sensitivity analysis did not alter the results significantly. Quality of life measures showed significant improvements in both groups; however, because of skewed data and the very small sample size of the studies, we did not perform a meta-analysis for health-related quality of life and functional impairment., Authors' Conclusions: There was no clear evidence of differences between supervised walking exercise and alternative exercise modes in improving the maximum and pain-free walking distance of patients with intermittent claudication. More studies with larger sample sizes are needed to make meaningful comparisons between each alternative exercise mode and the current standard of supervised treadmill walking. The results indicate that alternative exercise modes may be useful when supervised walking exercise is not an option for the patient.

Objective: Exercise therapy is a common intervention for the management of intermittent claudication (IC). However, considerable uncertainty remains about the effect of different exercise components such as intensity, duration, or content of the exercise programs. The aim of this study was to assess the effectiveness of supervised walking therapy (SWT) as treatment in patients with IC and to update and identify the most important exercise components resulting in an optimal training protocol for patients with IC., Methods: A systematic literature search using MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases was performed. Randomized controlled trials (RCTs) published between January 1966 and February 2012 were included if they evaluated the effectiveness of SWT. Predefined exercise components were extracted, including treadmill use during training, claudication pain end point used during walking, length of the SWT program, and total training volume. A meta-analysis and meta-regression was performed to evaluate the weighted mean difference in maximum walking distance (MWD) and pain-free walking distance (PFWD) between SWT and noninterventional observation., Results: Twenty-five RCTs (1054 patients) comparing SWT vs noninterventional observation showed a weighted mean difference of 180 meters (95% confidence interval, 130-230 meters) in MWD and 128 meters (95% confidence interval, 92-165 meters) in PFWD, both in favor of the SWT group. In multivariable meta-regression analysis, none of the predefined exercise components were independently associated with significant improvements in MWD or PFWD., Conclusions: SWT is effective in improving MWD and PFWD in patients with IC. However, pooled results from the RCTs did not identify any of the exercise components including intensity, duration, or content of the program as being independently associated with improvements in MWD or PFWD., (Copyright © 2012 Society for Vascular Surgery.

The production of IgG HLA antibodies after lung transplantation (LTx) is considered to be a major risk factor for the development of chronic rejection, represented by the bronchiolitis obliterans syndrome (BOS). It has recently been observed that elevated levels of IgM HLA antibodies also correlates with the development of chronic rejection in heart and kidney transplantation. This study investigates the relationship between IgM and IgG antibodies against HLA and MICA after lung transplantation. Serum was collected from 49 patients once prior to transplantation and monthly for up to 1 year after lung transplantation was analyzed by Luminex to detect IgM and IgG antibodies against HLA and MICA. The presence of either IgM or IgG HLA and/or MICA antibodies prior to or after transplantation was not related to survival, gender, primary disease, or the development of BOS. Additionally, the production of IgG alloantibodies was not preceded by an increase in levels of IgM, and IgM levels were not followed by an increase in IgG. Under current immune suppressive regimen, although the presence of IgM antibodies does not correlate with BOS after LTx, IgM( high) IgG( low) HLA class I antibody titers were observed more in patients with BOS compared to patients without BOS.
