RESUMEN
Background: To provide a continuous seal of the root canal, root-filling material should bond to the root canal dentin, ensuring the integrity of both the root-filling material and dentin remains in a static and functional state. The present study assessed the push-out bond strength of mineral trioxide aggregate (MTA) and cold ceramic (CC). Materials and Methods: In this laboratory trial study, 20 single-rooted, extracted human teeth without caries and cracks were selected. Each tooth was mounted in cold-curing resin. Then, 3 mm slices of mid-root dentin were obtained from each tooth. The specimens were randomly divided into two groups (n = 10) and filled with MTA ProRoot and CC. All specimens were stored for 30 days in an incubator at 37°C and 100% humidity. The push-out bond strength of the test materials was measured using a cylindrical punch with a 1-mm diameter. The punch was pushed against the test specimen at a speed of 1.0 mm/min using a universal material testing machine, extruding the filling test material. The push-out force during the test was recorded, and then, the internal surface of the teeth was examined to evaluate the mode of failure. Independent t-test and Chi-square were used to analyze the data. P < 0.05 was considered a significance threshold. Results: The mean push-out bond strength in the CC group was 24.58 (MPa), and in MTA ProRoot, it was 23.77. No significant difference was observed between the two groups. The most frequent mode of failure in both groups was adhesive failure. Conclusion: The two materials have adequate push-out bond strength to root dentin, and there is no difference between the bond strength and mode of failure of the two materials.
RESUMEN
Background and Aims: Adverse cutaneous drug reactions (ACDRs) are common and potentially life-threatening, while also hindering patient compliance to medications. Given the regional differences in patterns and prevalence of ACDRs, it is important to study the epidemiology, as well as the clinical and outcome patterns of patients with ACDRs in Iran. Methods: This cross-sectional study on ACDRs was conducted among hospitalized patients in a referral university hospital in the city of Isfahan, Iran. The patients' demographics, clinical information, and outcomes, including age, gender, past medical history, medication history, drug reaction with eosinophilia and systemic symptoms (DRESS) diagnosis, Steven-Johnson Syndrome (SJS) diagnosis, toxic epidermal necrosis (TEN) diagnosis, treatment regimen (steroids or intravenous immunoglobulin [IVIG]) and outcome information, including intensive care requirements, severe medical complications, or death, were obtained from medical records. Results: A total of 195 patients with a mean age of 40 years and consisting of 61% females were included. Carbamazepine, lamotrigine, sodium valproate, and phenytoin are the most commonly reported medications. Rate of complications was 45% with DRESS, SJS, and TEN diagnosed in 26%, 47%, and 19%, respectively. Treatment was carried out with steroids and IVIG in 81% and 19%, respectively. Among patients, 15% required intensive care and 5% died. Diagnosis of TEN, older age, and baseline heart disease were predictors of mortality. Patients with SJS were younger and more likely to be males, and they were more likely to have eye complications. On the other hand, patients with the diagnosis of TEN were more likely to receive IVIG and intensive care, and had a higher mortality rate. Conclusion: Our study provides insight into the demographics and clinical patterns of Iranian patients with ACDRs. This will help in predicting rates of complications, treatments, and outcomes in patients and therefore make proper management decisions.
RESUMEN
Macular amyloidosis (MA) is one of the most common types of primary localized cutaneous amyloidosis (PLCA), distributed predominantly over the trunk and extremities. Due to the vast therapeutic options, this study aims to compare the effectiveness of Q-switched Nd: YAG laser 1064 nm and Er: YAG laser 2940 nm in treating MA. This clinical trial was performed in 2020-2021 on 33 women with MA. In each patient, the lesion was randomly divided into two areas, A and B. Area A underwent four treatment sessions with 4-week intervals of Q-switched Nd: YAG laser 1064 nm. Area B underwent four treatment sessions with an Er: YAG laser 2940 nm at 4-week intervals. Degree of basal pigmentation and degree of pigmentation after treatment, pruritus intensity, before and after the treatment, and patient and physicians' satisfaction were measured and compared. The pruritus in patients improved significantly after the study (P < 0.001), but no significant differences could be observed between the two groups regarding the improvements (P > 0.05). We also found no significant differences between the two groups of patients regarding patient and physicians' satisfaction rates (P > 0.05). The use of both Q-switched Nd: YAG laser and Er: YAG laser resulted in improvements in terms of pruritus, patient and physicians' satisfaction, and total improvement in pigmentation of the lesions.

BACKGROUND: One of the main challenges of many societies in reducing and ageing of the population is marriage at an advanced age in women and decrease of producing offspring due to the concern of increasing the probability of maternal and neonatal outcomes. The mother's oxidative stress conditions during pregnancy affect mothers and their baby's health. Aging is one of the increasing factors of oxidants in the body. Aim of this study is the compartion total antioxidant capacity (TAC), total oxidants status (TOS), oxidative stress index (OSI) values, and maternal and neonatal outcomes in three groups of mothers with different age ranges from 20 to 29, 30 to 34, and 35 to 45 years old. METHODS: 164 pregnant women were grouped according to age into three groups: 25 to 30 (group I), 30 to 35 (group II), and 35 to 45 years old (group III). The umbilical cord blood samples were taken to the assay TAC, TOS, and OSI (TOS/TAC). The Kolmogorov-Smirnov test was employed to assess the normal distribution of countinus variables. The one-way ANOVA and Kruskal-Wallis test were used to compare anthropometric and biochemical factors between groups. RESULTS: TAC levels decreased non-significantly (438.2 ± 102; 431.7 ± 99.8; and 428.2 ± 100.26 for groups I, II, and III respectively, P value = 0.99), TOS levels increased significantly (23.93 ± 11.7; 25.4 ± 12.3; and 28.2 ± 12.7 for groups I, II, and III respectively, P value = 0.034), and OSI increased non-significantly with increasing maternal age (0.055 ± 0.044; 0.091 ± 0.031; 0.069 ± 0.005, for groups I, II, and III respectively, P value = 0.14). Increasing age did not significantly affects the maternal and infant birth outcomes. CONCLUTION: The results showed that the increasing the age of the mother up to 45 doesn't have a significant effects on the value of OSI and the maternal and infant outcomes.

OBJECTIVES: The objective of this current survey was to assess both the occurrence and severity of pre- and post-endodontic pain among female individuals, distinguishing between those with anemia and those without. MATERIALS AND METHODS: In the current study, we included a total of 60 women with anemia (hemoglobin < 11) and those without anemia (hemoglobin > 13). We recorded the occurrence and severity of pain before and at 24, 48, and 72 h following root canal treatment using a visual analog scale (VAS) ranging from 0 to 10. Additionally, we collected data on patient age, tooth type, as well as pulpal and periapical conditions. Statistical analysis was carried out using two-way ANOVA, pairedt-tests, and Pearson correlation coefficient. The significance level for statistical tests was set at p ≤ .05. RESULTS: The incidence of preoperative pain in both anemic and non-anemic patients was 80%. The total incidence of post-operative pain was recorded as 71.7% (82.2% in anemic and 61.1% in non-anemic women). Compared with the pretreatment pain incidence and intensity, the values increased in 24 h but declined in 48 h and 72 h after treatment. Considering the posttreatment pain intensity, the mean values were higher in the three time intervals (24, 48, and 72 h) in anemic patients. Pulpal and periapical status, in contrast to age and tooth type, significantly contributed to the intensity of posttreatment pain. CONCLUSION: Regarding the importance of pain phenomenon in human life, it is recommended to consider anemia as an important risk factor for post-endodontic pain. Early diagnosis and analgesic treatment interventions in anemic females, alongside the pain control during root canal treatment, could promote the patient's satisfaction and quality of care.

INTRODUCTION: Alopecia areata (AA) is an autoimmune non-scarring hair loss. The role of micronutrients such as iron, zinc, and vitamins, especially vitamin D, on the natural hair cycle is well defined in literature. This study aims to evaluate the correlation between vitamin D and CRP levels in patients with alopecia areata. METHODS: This cross-sectional study was performed from beginning of October 2020 until end of December 2021. Alopecia areata patients over 18 years of age gave their written consent to participate in the study. The severity of the patients' disease was assessed using the Severity of Alopecia Tool. Serum vitamin D and CRP levels were measured and CBC and LFT were also performed. RESULTS: There were significant differences between the patients with the localized form of AA and its universal form in the following variables: Vitamin D levels, SALT score, WBC, ALKP, and CRP. There was also a significant inverse correlation between CRP and vitamin D levels (p < 0.0001). CONCLUSION: Vitamin D deficiency is associated with higher CRP levels, and patients with low serum vitamin D and high CRP levels are at a higher risk of developing the universalis form of AA; therefore, these patients should undergo more aggressive treatments.
RESUMEN
BACKGROUND: This study aimed to assess the effect of blood contamination on marginal adaptation of cold ceramic (CC) and mineral trioxide aggregate (MTA) Angelus using scanning electron microscopy (SEM). METHODS: This in vitro experimental study was conducted on 24 extracted single-rooted human teeth. After cleaning and shaping, the root canals were filled with lateral compaction technique. The apical 3 mm of the roots was cut, and cavities with 3 mm depth were created at the apex. The teeth were randomly assigned to two group (n = 12) for the application of CC and MTA Angelus as retrograde filling materials. CC and MTA Angelus were prepared by mixing the powder with blood, and applied in the cavities. After 24 h, their marginal adaptation to the canal walls was assessed by SEM. Data were statistically analyzed by t-test (alpha = 0.05). RESULTS: The mean marginal gap was 8.98 µm in the CC, and 16.26 µm in the MTA Angelus group; this difference was statistically significant (P < 0.001). CONCLUSIONS: The present in vitro study revealed that following complete blood contamination of powder, CC showed significantly superior marginal adaptation than MTA Angelus as shown by SEM assessment.

Background: Stigmatization and discrimination by health workers, particularly midwives are obstacles to the achievement of universal access to Human Immunodeficiency Virus (HIV) prevention, treatment, and care programs. Therefore, it is necessary to evaluate midwifery students' knowledge and attitude regarding Acquired Immune Deficiency Syndrome (AIDS) and HIV, and their willingness to care for patients with AIDS and HIV before they enter the field of health and medical activities. Thus, the aim of this study was to investigate the level of knowledge and attitude in this regard, and willingness to care for patients with AIDS and HIV among midwifery students of selected universities in Iran in 2020. Materials and Methods: A descriptive-analytical, cross-sectional study was performed on 618 midwifery students in Iran in 2019-2020. Data were collected using a five-part questionnaire: a demographic characteristics form, an academic profile form, the HIV Knowledge Questionnaire (HIV-KQ), the AIDS Attitude Scale (AAS), and the Jordan Standard Questionnaire. Data analysis was performed through descriptive and inferential statistical methods. p value of ≤ 0.05 was considered significant. Results: The mean (SD) age of the subjects was 23.10 (5.63) years. The mean (SD) of knowledge, attitude, and willingness scores were 26.93 (6.64), 80.45 (9.27), and 29.55 (9.10), respectively. Single individuals had higher attitude scores. Conclusions: Iranian midwifery students had the desired level of knowledge, although the mean score was not much higher than the threshold. The level of the midwifery students' attitude was appropriate and more than that, but none of them had a 100% positive attitude. They had a moderate or neutral willingness to provide services to and care for patients with AIDS.
RESUMEN
BACKGROUND: Androgenetic alopecia (AGA) is the most common type of hair loss in men, and several treatment options have been proposed for it. Fractional ablative erbium YAG laser can promote hair growth through trans-epidermal drug delivery and the thermal stimulation of hair follicles; this study therefore aims to evaluate minoxidil alone and in combination with fractional ablative erbium YAG laser in male patients with AGA. METHODS: This study was performed on 30 male patients with moderate to severe AGA. Patients were equally randomized into two groups, and the intervention group was treated with 1 mL of topical 5% minoxidil twice daily and six sessions of 2940-nm ablative fractional erbium YAG laser, and the control group received topical 5% minoxidil alone. The assessment entailed photography, dermoscopy, and patient satisfaction based on a 7-point grading scale. RESULTS: Both groups showed statistically significant improvements in terms of patient satisfaction, photography, and dermoscopy scores. The group receiving a combination of laser and minoxidil treatment obtained a higher dermoscopy score than the patients receiving minoxidil alone (p-value = 0.016). Nonetheless, there was no difference between the two groups in terms of the photography score (p-value = 0.13). CONCLUSION: Laser treatment can stimulate the hair follicles and also enhance the dermal delivery of minoxidil, which was found to be associated with slightly better outcomes in this study.

Objective: Metabolic syndrome is a risk factor affecting reproductive health and pregnant outcomes. So far, the effect of this syndrome on the success rate of assisted reproduction techniques (ART) has not been investigated. The aim of this study was to investigate the relationship between metabolic syndrome and the success rate of ART in infertile women in Isfahan. Materials and methods: A prospective cohort study performed on 147 women candidates using in-vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) and/or ICSI methods referred to Isfahan Infertility Center in two groups with metabolic syndrome(n=49) without metabolic syndrome(n=98), by convenience sampling methods in Isfahan, Iran in 2018. Body mass index (BMI) and waist, abdominal circumference, Serum triglyceride (TG), cholesterol and FBS were measured. If ßHCG test was positive (day 15-16 after ART), transvaginal sonography (TVS) was done 15 days later. Pregnant women were followed up to the 20th week of pregnancy. To analyze, t-test, chi-square and logistic regression tests were used. Results: The frequency of metabolic syndrome was 33.4% (n=49). The frequency of ART was not significantly different between women with and without metabolic syndrome (p=0.321). The relative frequency of pregnancy (p=0.907) and abortion (p=0.896) did not show a significant difference between the two groups. Independent t-test showed that the mean FBS, HDL, TG, systolic and diastolic BP, abdominal circumference and BMI in the studied units did not differ significantly based on the occurrence of pregnancy and abortion. Conclusion: According to the results of this study, there was no significant difference between the indicators of metabolic syndrome and the success rate of ART in achieving, pregnancy and pregnant outcomes in the first twenty weeks of pregnancy.
RESUMEN
Immune checkpoint blockade therapy is beneficial and even curative for some cancer patients. However, the majority don't respond to immune therapy. Across different tumor types, pre-existing T cell infiltrates predict response to checkpoint-based immunotherapy. Based on in vitro pharmacological studies, mouse models and analyses of human melanoma patients, we show that the cytokine GDF-15 impairs LFA-1/ß2-integrin-mediated adhesion of T cells to activated endothelial cells, which is a pre-requisite of T cell extravasation. In melanoma patients, GDF-15 serum levels strongly correlate with failure of PD-1-based immune checkpoint blockade therapy. Neutralization of GDF-15 improves both T cell trafficking and therapy efficiency in murine tumor models. Thus GDF-15, beside its known role in cancer-related anorexia and cachexia, emerges as a regulator of T cell extravasation into the tumor microenvironment, which provides an even stronger rationale for therapeutic anti-GDF-15 antibody development.

Background: This study aimed to evaluate the reaction of the periapical tissue to Cold ceramic and mineral trioxide aggregate (MTA) following periapical endodontic surgery. Materials and Methods: In this experimental study, a total of 12 mandibular first, second, and third premolars of two male dogs were selected. All procedures were performed under general anesthesia. The access cavities were prepared, and the length of canals was determined. Root canal treatment was performed. A week later, periradicular surgery was performed. After osteotomy, 3 mm of the root end was cut. Then, a 3-mm cavity was created by an ultrasonic. The teeth were randomly divided into two groups (n = 12). The root-end cavities were filled with MTA in the first group and with Cold ceramic in the second group. After 4 months, the animals were scarified. Histological evaluation of the periapical tissues was performed. Data were analyzed using SPSS 22 and Chi-square test and P = 0.05. Results: The findings showed 87.5% and 58.3% cementum formation in MTA and Cold ceramic groups, respectively, indicating a significant difference (P < 0.001). In addition, the results showed 91.7% and 83.3% bone formation in MTA and Cold ceramic groups, respectively, but the difference was not statistically significant (P = 0.6). Furthermore, the findings revealed 87.5% and 58.3% periodontal ligament (PDL) formation in MTA and Cold ceramic groups, respectively (P = 0.05). Conclusion: Cold ceramic was able to induce the regeneration of cementum, bone, and PDL; hence, it can be considered as a biocompatible root-end filling material in endodontic surgery.
RESUMEN
Recent advances in wearable energy harvesting technology as solutions to occupational health and safety programs are presented. Workers are often exposed to harmful conditions-especially in the mining and construction industries-where chronic health issues can emerge over time. While wearable sensors technology can aid in early detection and long-term exposure tracking, powering them and the associated risks are often an impediment for their widespread use, such as the need for frequent charging and battery safety. Repetitive vibration exposure is one such hazard, e.g., whole body vibration, yet it can also provide parasitic energy that can be harvested to power wearable sensors and overcome the battery limitations. This review can critically analyze the vibration effect on workers' health, the limitations of currently available devices, explore new options for powering different personal protective equipment devices, and discuss opportunities and directions for future research. The recent progress in self-powered vibration sensors and systems from the perspective of the underlying materials, applications, and fabrication techniques is reviewed. Lastly, the challenges and perspectives are discussed for reference to the researchers who are interested in self-powered vibration sensors.
RESUMEN
Background: Acne is a dermatologic condition with a high burden in terms of psychosocial consequences as a result of scars remaining on the skin. Its effects are severe in adolescence and finding treatments with short therapy courses, superior results, and fewer adverse effects are of high importance. Materials and Methods: We included 30 individuals with acne vulgaris scars in Al-Zahra academic training hospital from June 2018 to Jan 2019. Each individual received both fractional CO2 and fractional Er:YAG lasers on right and left sides of the face, respectively. Three sessions of laser treatment were applied to each side with one-month intervals. Results were evaluated by patients according to subjective satisfaction and physicians' assessment and photo evaluation by two blinded dermatologists. Improvement was graded by a quartile grading scale: less than 25%: mild, 25% to 50%: moderate, 51% to 75%: good, and 76% to 100%: excellent response. Assessments were obtained at baseline and one month after the last visit. Results: Based on subjective satisfaction (p < 0.05) and physicians' assessment (p < 0.01), fractional CO2 laser was significantly more effective than Erbium:YAG laser. Also, Post-treatment side effects were mild and transient in both groups. Conclusion: Laser therapies are common in the treatment of scars and each modality has special advantages and disadvantages. Choosing among them should be based on various criteria. Fractional CO2 lasers have been revealed favorable results in most reports. Large comprehensive trials could help experts in choosing among alternatives for different subgroups.
RESUMEN
Current treatment regimens in cancer cases cause significant side effects and cannot effectively eradicate the advanced disease. Hence, much effort has been expended over the past years to understand how cancer grows and responds to therapies. Meanwhile, proteins as a type of biopolymers have been under commercial development for over three decades and have been proven to improve the healthcare system as effective medicines for treating many types of progressive disease, such as cancer. Following approving the first recombinant protein therapeutics by FDA (Humulin), there have been a revolution for drawing attention toward protein-based therapeutics (PTs). Since then, the ability to tailor proteins with ideal pharmacokinetics has provided the pharmaceutical industry with an important noble path to discuss the clinical potential of proteins in oncology research. Unlike traditional chemotherapy molecules, PTs actively target cancerous cells by binding to their surface receptors and the other biomarkers particularly associated with tumorous or healthy tissue. This review analyzes the potential and limitations of protein therapeutics (PTs) in the treatment of cancer as well as highlighting the evolving strategies by addressing all possible factors, including pharmacology profile and targeted therapy approaches. This review provides a comprehensive overview of the current state of PTs in oncology, including their pharmacology profile, targeted therapy approaches, and prospects. The reviewed data show that several current and future challenges remain to make PTs a promising and effective anticancer drug, such as safety, immunogenicity, protein stability/degradation, and protein-adjuvant interactions.

Polymeric gel-based artificial muscles exhibiting tissue-matched Young's modulus (10 Pa-1 MPa) promise to be core components in future soft machines with inherently safe human-machine interactions. However, the ability to simultaneously generate fast, large, high-power, and long-lasting actuation in the open-air environment, has yet been demonstrated in this class of ultra-soft materials. Herein, to overcome this hurdle, the design and synthesis of a twisted and coiled liquid crystalline glycerol-organogel (TCLCG) is reported. Such material with a low Young's modulus of 133 kPa can surpass the actuation performance of skeletal muscles in a variety of aspects, including actuation strain (66%), actuation rate (275% s-1 ), power density (438 kW m-3 ), and work capacity (105 kJ m-3 ). Notably, its power density is 14 times higher than the record of state-of-the-art polymeric gels. No actuation performance degradation is detected in the TCLCG even after air exposure for 7 days, owing to the excellent water retention ability enabled by glycerol as co-solvent with water. Using TCLCG, mobile soft robots with extraordinary maneuverability in unstructured environments are successfully demonstrated, including a crawler showing fast bidirectional locomotion (0.50 mm s-1 ) in a small-confined space, and a roller that can escape after deep burying in sand.
RESUMEN
Background: Infertility is a psychological crisis for a couple, spouse, and their families. Due to the positive effects of spiritual intelligence on the positive adaptation and growth of the individual under difficult circumstances, this study was conducted to determine the relationship between spiritual intelligence and resilience in infertile couples in Isfahan. Materials and Methods: This cross-sectional study was performed in 2020 on 162 infertile couples. Data were collected by the convenience sampling method from infertile couples referring to Infertility Centers in Isfahan through two standard questionnaires. Data analysis was performed using descriptive statistical methods for quantitative variables. The relationship between spiritual intelligence and resilience score was investigated using inferential statistical methods of Pearson's correlation coefficient and multiple linear regression. A p value of less than 0.05 was considered significant. Results: The results showed that the mean age Standard Deviation (SD) of women and their spouses was 32.01 (5.86) and 36.30 (5.82) years, respectively. Pearson's correlation coefficient showed that there was a significant positive direct relationship between resilience score with total spiritual intelligence score (r = 0.36, p < 0.001) and its dimensions Critical Existential Thinking (CET) (r = 0.60, p < 0.001), personal meaning production (PMP) (r = 0.38, p < 0.001), Transcendental Awareness (TA) (r = 0.43, p < 0.001), and Conscious State Expansion (CSE) (r = 0.53, p < 0.001). The PMP (t = 6.38, p < 0.001) and the CSE (t = 2.15, p = 0.03) were significant predictors of resilience scores. Conclusions: The result of our study showed that couples with a higher level of spiritual intelligence had a better understanding of the problems and harms of primary infertility and would cope with it more efficiently.
RESUMEN
Background: Cutaneous manifestations of coronavirus disease 2019 (COVID-19) range from mild skin rashes to severe vasculitis. In the current study, we evaluated the demographic characteristics of the patients with cutaneous vasculitis following COVID-19 infection. Materials and Methods: In the current study, we evaluated 799 hospitalised patients with COVID-19 infection for development of cutaneous vasculitis. Demographic and clinical characteristics of the patients were obtained using questionnaires and patients' records. Cutaneous vasculitis of the suspected patients were confirmed using skin biopsy and direct immunofluorescence. Results: We detected 24 hospitalised cases with cutaneous vasculitis presenting with petechia, purpura, livedoretcularis and acrocyanosis. Our data showed a significant relationship between male sex, advanced age, C-reactive protein (CRP) level and presence of comorbidities with development of cutaneous vasculitis. In addition, we found a positive association between the severity of COVID-19 infection and occurrence of cutaneous vasculitis. Conclusion: Our findings are suggestive that clinicians must be aware of cutaneous vasculitis risk as prognostic value in the patients with severe COVID-19 infection.
RESUMEN
INTRODUCTION: Body composition as dynamic indices constantly changes in pregnancy. The use of body composition indices in the early stages of pregnancy has recently been considered. Therefore, the current meta-analysis study was conducted to investigate the relationship between body composition in the early stages of pregnancy and gestational diabetes. METHOD: Valid databases searched for papers published from 2010 to December 2021 were based on PRISMA guideline. Newcastle Ottawa was used to assess the quality of the studies. For all analyses, STATA 14.0 was used. Mean difference (MD) of anthropometric indices was calculated between the GDM and Non-GDM groups. Pooled MD was estimated by "Metan" command, and heterogeneity was defined using Cochran's Q test of heterogeneity, and I 2 index was used to quantify heterogeneity. RESULTS: Finally, 29 studies with a sample size of 56438 met the criteria for entering the meta-analysis. Pooled MD of neck circumference, hip circumference, waist hip ratio, and visceral adipose tissue depth were, respectively, 1.00 cm (95% CI: 0.79 to 1.20) [N = 5; I^2: 0%; p: 0.709], 7.79 cm (95% CI: 2.27 to 13.31) [N = 5; I2: 84.3%; P<0.001], 0.03 (95% CI: 0.02 to 0.04) [N = 9; I2: 89.2%; P<0.001], and 7.74 cm (95% CI: 0.11 to 1.36) [N = 4; I^2: 95.8%; P<0.001]. CONCLUSION: Increased neck circumference, waist circumference, hip circumference, arm circumference, waist to hip ratio, visceral fat depth, subcutaneous fat depth, and short stature increased the possibility of developing gestational diabetes. These indices can accurately, cost-effectively, and affordably assess the occurrence of gestational diabetes, thus preventing many consequences with early detection of gestational diabetes.
