RESUMO

OBJECTIVE: To explore the potential associations between pregnancy cravings and various sociodemographic, lifestyle and health factors. DESIGN: Cross-sectional study. SETTING: Population-based study in Jordan. PARTICIPANTS: A total of 500 women who had children and experienced pregnancy cravings were included. PRIMARY AND SECONDARY OUTCOME MEASURES: Pregnancy cravings are prevalent among Jordanian women and associated with some sociodemographic, lifestyle and health factors. RESULTS: The results showed that 75.40% (377/500) of women experienced food cravings, with 40.6% and 29.1% of them having iron deficiency and vitamin D deficiency, respectively. The most commonly craved food items were sweets (17.2%, 86/500) and salts (22.2%, 115/500), while less than 1.0% of women craved non-food items. No significant correlation (p>0.05) was found between food cravings and the gender of the babies. Significant associations were found between food cravings and the mother's educational level (p=0.023), weight loss (p<0.001) and diseases such as anaemia (p=0.01). CONCLUSION: Pregnancy cravings, particularly for food items, with sweets and salts being the most commonly craved, are prevalent among Jordanian women and are associated with the mother's educational level, changes in weight and the presence of anaemia. Additionally, the study found that iron and vitamin D deficiencies are prevalent health issues among women experiencing these cravings in Jordan. This research has important implications, emphasising the pressing need for targeted nutritional interventions and healthcare strategies to address identified deficiencies and improve maternal health outcomes in the region.

RESUMO

The contribution of pyridoxine on various human disorders has been revealed in so many studies; however, this contribution on poor semen quality has yet to be investigated. Here, we intended to measure the level of seminal plasma pyridoxine (SPP) in men with oligozoospermia compared to normozoospermic men. Thirty-three men with oligozoospermia and forty-three normozoospermic men were randomly enrolled in this study. Collected semen were tested for sperm motility, sperm concentration, semen volume, and pyridoxine status. Liquid chromatography with tandem mass spectrometry was used to measure SPP in the collected samples. There was a significant reduction (p < 0.0001) in the concentrations of SPP in men with oligozoospermia (0.79 ± 0.41 µg L-1) compared to normozoospermic men (3.17 ± 0.96 µg L-1). Besides, SPP was not significantly correlated (p > 0.05) with sperm motility, sperm concentration, and semen volume in both tested groups, but, independently, it was found to be positively correlated (p = 0.0154) with male age in oligozoospermic group. Men with oligozoospermia had lower level of SPP compared to normozoospermic men. These results may open a new research gate for the use of pyridoxine in the management of male infertility.

RESUMO

This work investigates the effect of the alcoholic extract of Anabasis syriaca Iljin on biochemical and histological parameters in male rats. The lethal dose (50% of the plant extract) was assessed, and three separate doses (1/10th, 1/15th, and 1/20th) were orally gavaged for two weeks into three study groups of animals (five rats in each group), with one group used as a control and gavaged normal saline via the same route. Blood was collected after overnight fasting, and 24 biochemical parameters were evaluated. The gross and microscopic findings were reported after the collection of specimens from the animals and processed routinely for standard histological procedures. Among all tested biochemical parameters, a significant increase was noted in fasting serum glucose (p ≤ 0.010), troponin (p ≤ 0.001), and creatine kinase (p ≤ 0.001), while a significant decrease was found in triglycerides (p ≤ 0.001) and low-density lipoprotein (p=0.001). On the other hand, no significant histopathological lesions were present within the examined tissues of all groups. In conclusion, ethanolic extract of Anabasis syriaca negatively affected the cardiac function of male rats and increased their serum glucose but reduced their serum triglycerides and low-density lipoprotein.

RESUMO

OBJECTIVE: Parkinson's disease (PD) is associated with non-motor complications such as sleep disturbance and depression. Transcranial direct current stimulation (tDCS) showed therapeutic effects on the motor dysfunctions. However, the potential effects of tDCS therapy on melatonin hormone, sleep dysfunctions, and depression in patients with PD still unclear. This feasibility study aimed to identify any potential changes in melatonin serum level, sleep functions and depression after the bilateral anodal tDCS in patients with PD. MATERIAL AND METHODS: Tensessions of bilateral anodal tDCS stimulation applied over left and right prefrontal and motor areas were given to twenty-five patients with PD. Melatonin serum level, Pittsburgh sleep quality index, and geriatric depression scale examined before and after tDCS stimulation. RESULTS: After bilateral anodal tDCS, there was a significant reduction in melatonin serum level, improvement in depression, improvements in overall sleep quality, and sleep latency. Correlations test showed significant associations between melatonin serum level reduction and changes in subjective sleep quality, and sleep duration, as well as between improvements in depression and overall sleep quality, sleep latency, and sleep disturbance. CONCLUSION: Bilateral anodal tDCS therapy was a feasible and safe tool that showed potential therapeutic effects on melatonin serum level, sleep quality, and depression level in patients with PD. Although the further large scale and randomized-control trial studies are crucially needed, there is still a need for such a feasibility study to be established before such trials can be implemented as is recommended in the new medical research council guidelines.

RESUMO

Even though the effect of caffeine on humans' health has been revealed in various research studies, its effect on semen quality has yet to be well explained. Here, we measured the effect of caffeine at 1, 5, 10 and 20 mM on motility of human spermatozoa in normozoospermic and asthenozoospermic semen samples, level of seminal nitric oxide, chelation of seminal calcium ions and activity of seminal creatine kinase. Fifty-one normozoospermic and ten asthenozoospermic semen samples were recruited in this study. Sperm motility was evaluated by Makler counter, and seminal nitric oxide, seminal-free calcium and activity of seminal creatine kinase were measured spectrophotometrically. Caffeine at 10 mM significantly (p < .05) increased progressive motility of spermatozoa in both tested groups. Also, caffeine significantly increased (p < .05) activity of creatine kinase and insignificantly (p > .05) altered nitric oxide and free calcium levels in seminal plasma. In conclusion, progressive motility of human spermatozoa was found to be higher in the presence of caffeine at 10 mM in normozoospermic and asthenozoospermic semen samples; this increase, albeit partially, could be due to increased activity of seminal creatine kinase, but not to increased production of nitric oxide or chelation of free calcium ions.

RESUMO

Lately, there is a systematic research consensus that reveals adverse effects of aspirin on semen quality characteristics; however, such consensus is lacking further confirmation by human studies. Therefore, here, we asked whether sperm motility and vitality are affected in the presence of aspirin at 0.1 and 1 mM in the ejaculated semen, and whether such effect may be due to an alteration in seminal calcium ions or seminal nitric oxide production. Forty-three semen samples from different normozoospermic men were recruited in this study. Sperm motility was measured by Makler counting chamber, and sperm vitality was measured by Eosin test. Calcium chelating effect of aspirin and seminal nitric oxide production was measured spectrophotometrically. Aspirin at both tested concentrations significantly (p < .05) reduced progressive grade-a motility and vitality of spermatozoa. Additionally, aspirin was found to have significant ability (p < .05) to bind seminal calcium ions, but insignificantly reduced the amount of seminal nitric oxide. In conclusion, sperm motility and vitality were reduced in the presence of aspirin at 0.1 and 1 mM in semen. Such reduction may be attributable to the ability of aspirin to chelate seminal calcium ions, but not to an alteration in the amount of nitric oxide produced.

RESUMO

BACKGROUND: Parkinson's disease (PD) is a multisystem-progressive neurodegenerative disease characterized by dopaminergic neurons, however, the role of the non-dopaminergic system (such as melatonin hormone) in the pathogenesis of PD is now emerging. OBJECTIVE: To identify any potential correlation between the dopamine and melatonin serum levels, and motor, cognitive, and sleep dysfunctions in patients with PD. METHOD: Cross-sectional piloting study conducted with a sample of 34 patients with PD (aged 50-72 yrs old). Correlation tests performed to identify any potential correlations between the biomarkers' serum levels and motor, cognitive, and sleep dysfunctional levels in "on-medication" status. RESULTS: Spearman's test showed significant correlations between the melatonin serum level and sleep dysfunctions including overall sleep quality (P = 0.010) and subjective sleep quality sub-score (P = 0.001). On the other hand, spearman's test showed significant correlations between the dopamine serum level and motor dysfunctions including Berg Balance Scale (P = 0.026), 10-Meter Walk Test (P = 0.016), and Fear of Falling Index (P = 0.007), as well as comparisons between the dopamine serum level and cognitive dysfunction (P = 0.048). CONCLUSIONS: Melatonin serum level would serve as a potential biomarker in understanding the PD pathogenesis, and the melatonin serum level should be considered in future studies related to PD besides the dopamine serum level.

RESUMO

Although lansoprazole (brand name Prevacid) is a commonly used dug to manage various acid-related gastrointestinal diseases, little is known about its effects on human semen quality and sperm parameters. Here, we aimed to investigate the effect of lansoprazole on DNA integrity of human spermatozoa and activity of seminal creatine kinase. DNA integrity of human spermatozoa was assessed by the Apo-Direct™ kit followed by flow cytometry. The activity of creatine kinase was measured by kinetic spectrophotometric method using commercially available kits following the International Federation of Clinical Chemistry recommendations. Lansoprazole at 3 µg/ml, after 1-hr incubation period, did not show any significant increase in fluorescein isothiocyanate fluorescence (p > .05) and hence on the content of DNA breaks of human spermatozoa. In addition, there was no significant change (p = .8113) in the activity of seminal creatine kinase by the effect of lansoprazole. In conclusion, lansoprazole at 3 µg/ml did not alter DNA integrity of human spermatozoa or activity of seminal creatine kinase after 1-hr incubation period.

RESUMO

Pomegranate juice (PGJ) is rich in unique bioactive compounds that can be used in the management of various diseases/disorders such as cancer, heart disease, Alzheimer disease, hypertension, and diabetes. Here, we aimed to investigate the effects of fresh PGJ on levels of melatonin, insulin, and fasting blood glucose in people with impaired fasting glucose (IFG). The study was a randomized clinical trial in which 28 participants (10 males, 18 females) with IFG were recruited from Irbid Central Laboratory and the Diabetes Clinic of the University Hospital at Jordan University of Science and Technology. Blood specimens from each participant were collected before (-5 min), and 1 and 3 hr after PGJ administration at 1.5 ml/kg of the body weight, and melatonin, insulin, and glucose were measured. People with IFG, but not healthy individuals, had significant antihyperglycemic response (p < .0001) to PGJ 3 hr after ingesting the juice. This response was not correlated with the age of participants (p = .4287). In addition, homeostatic model assessment of insulin resistance was significantly decreased (p < .0001) among people with IFG 3 hr after ingesting the juice. Moreover, 1 hr after PGJ administration, decreases in melatonin and increases in insulin were significantly observed among healthy (p = .0284, p = .0017) and IFG (p = .0056, p = .0007) individuals, respectively. In conclusion, fresh PGJ lowers melatonin, increases the level of insulin, and ameliorates insulin resistance in people with IFG.

RESUMO

According to the PubMed data base, there are at least fifty published articles that link between aspirin and semen quality. However, such link has yet to be comprehensively discussed and summarised. This work reviews and summarises the effect of aspirin on semen quality and sperm fertility characteristics, and hence on semen fertilising ability. To achieve this contribution, an electronic search of PubMed and Scopus databases was conducted for original manuscripts, presented from January 1974 through September 2019, via the keywords "aspirin" and "acetylsalicylic acid" versus "sperm" and "semen." In summary, there is a scientific research consensus that reveals negative effects of aspirin on semen quality. Still, clinical studies that directly examine the effect of aspirin on the main semen quality parameters are needed to support this conclusion. Mechanistically, the negative documented effect of aspirin on semen quality parameters may be attributable to decreased synthesis of testosterone, reduced function of nuclear factor kappa-light-chain-enhancer of activated B cells, decreased formation of testicular prostaglandins, reduced production of seminal nitric oxide and increased oxidative injury to sperm.

RESUMO

BACKGROUND: Chromium was found to be crucial for several biochemical processes in the human body, including, in particular, carbohydrate and lipid metabolism whereas the exact mechanisms of its actions have yet to be explored. Here, we asked whether low serum chromium levels are present in Jordanian smokers and Jordanians with prediabetes and type 2 diabetes (T2D), with hypertension, with overweight and obesity, and with a family history of diabetes. METHODS: A total of 360 patients (120 with T2D, 120 with prediabetes, and 120 healthy controls) were recruited randomly based on the American Diabetes Association criteria. Smokers (n = 26), and patients with hypertension (n = 46), with overweight (n = 47) and obesity (n = 57), and with family history of diabetes (n = 63) were included in the tested population. Serum chromium concentration was measured using the graphite furnace atomic absorption spectrometry. RESULTS: The results from this study revealed significant increase (P = 0.001 univariate, P = 0.038 multivariate) and significant decrease (P = 0.046 univariate,P = 0.038 multivariate) in serum chromium concentrations in smokers and people with T2D and prediabetes, respectively. In addition, serum chromium insignificantly altered (P > 0.05) in people with hypertension, with a family history of diabetes, and with overweight or obesity. CONCLUSIONS: Higher levels of serum chromium were observed in smokers, whereas lower levels were found to be present in patients with T2D and patients with prediabetes. In addition, serum chromium level may not be affected by hypertension, overweight and obesity, and family history of diabetes.

RESUMO

Pomegranate juice (PJ) has been recognized to have various biological benefits in several pathological conditions. One such benefit is the augmentation of hemoglobin level and the number of erythrocytes in the human body. Here, we assessed the short-term effect of fresh PJ on the level of Erythropoietin (EPO) in patients with type 2 diabetes (T2D) compared to healthy individuals. Blood samples from 59 participants with T2D and 30 healthy individuals were collected after a 12-hour fast and 3 hours after administration of fresh PJ at 1.5 mL per kg body weight. Serum glucose was measured by standard method and commercially available chemiluminescent immunoassay kits were used to determine serum EPO concentration. Mean changes in serum EPO levels 3 hours after ingesting PJ and before the juice ingestion (EPO response to PJ) for both diabetic and healthy participants were -2.002 ± 0.541 vs. - 0.041 ± 0.214, respectively (P = 0.0087). This EPO response to PJ was found not to be correlated with age (P = 0.6622) and gender (P = 0.5354) for patients with T2D, while a negative correlation (P = 0.0183) between EPO response to PJ and fasting serum glucose concentrations was observed in these patients. In conclusion, fresh PJ reduced serum EPO level in patients with T2D, but not in healthy individuals, 3 hours after ingesting the juice. The EPO response to PJ was found to be negatively correlated with fasting serum glucose, but not with age and gender, of patients with T2D. This trial is registered with ClinicalTrials.gov Identifier. NCT03902288.

RESUMO

There is increasing evidence that oxidative stress is a causal factor in different neurodegenerative disorders such as Alzheimer's disease and epilepsy. High-fat diet (HFD) has been shown to induce oxidative stress and neuronal damage that may increase susceptibility to seizures. The present study was undertaken to investigate the relationships between vitamin E, a potent antioxidant, HFD, and chemically induced seizures, using the PTZ seizure model in rats. Animals were randomly assigned into four groups: control, HFD, vitamin E (Vit E), and high-fat diet with vitamin E (HFD + Vit E) group. Vitamin E and/or HFD were administered to animals for 6 weeks. Thereafter, PTZ seizure threshold was measured in control and treated rats, and different brain regions were analyzed for levels of oxidative stress biomarkers. Current results revealed a significant reduction in PTZ seizure threshold in rats consuming HFD, which could be prevented by vitamin E supplement. Alongside, vitamin E supplement prevented HFD induced changes in oxidative stress biomarkers and capacity enzymes. Therefore, current results suggest that prolonged consumption of HFD increases susceptibility to PTZ induced seizures, which may be related to HFD induced oxidative stress. This increase in the PTZ susceptibility could be prevented by the administration of vitamin E, probably through its antioxidant effect, particularly at the brain hippocampal region.

RESUMO

Cryopreservation-thawing of human semen was found to reduce the level of antioxidant activity surrounding the sperm, which may negatively affect post-cryopreservation (post-thaw) recovery of sperm motility. Therefore, the current manufactured cryoprotectant media have been supplemented with certain antioxidants to preserve the loss in seminal antioxidant activity. In this study, we aimed to explore the correlation between total antioxidant capacity (TAC) of human semen samples before cryopreservation and the post-thaw recovery of sperm motility. Normal semen specimens (n = 77) were recruited in this study. Sperm motility was measured for each semen sample before and after cryopreservation and the post-thaw recovery of sperm motility was calculated. Seminal TAC was measured spectrophotometrically before cryopreservation for each semen sample using the sensitive cupric ion-reducing antioxidant capacity (CUPRAC) method. The results from this study showed that the post-thaw recovery of sperm motility is negatively correlated (p = 0.0404, p = 0.0402) with the absorbance at 450 nm and the values of seminal TAC in terms of µM Trolox equivalents, as evaluated by CUPRAC, respectively. In conclusion, the total antioxidant reservoir in each ejaculated semen specimen could be a factor in determining the post-thaw recovery of sperm motility toward lower recovery for semen specimens of high antioxidant content.

RESUMO

BACKGROUND Sleep dysfunctions impose a large burden on quality of life for patients with Parkinson's disease (PD). Several studies on PD reported potential therapeutic effects of transcranial direct current stimulation (tDCS) on motor and non-motor functions, but not related to sleep quality. Therefore, the present study examined sleep quality, depression perception, and quality of life changes after bilateral anodal tDCS in patients with PD. MATERIAL AND METHODS Twenty-one patients (n=21) with PD underwent 10 sessions (20 min each, 5 per week) of bilateral anodal tDCS stimulation applied simultaneously over the left and right prefrontal and motor areas. The Pittsburgh Sleep Quality Index (PSQI) total score and sub-scores, Geriatric Depression Scale (GDS), and Health-related quality of life questionnaire (SF-36) were measured pre/post bilateral tDCS anodal stimulation. RESULTS PSQI total score (P=0.045), sleep latency sub-score (P=0.02), and GDS total score (P=0.016) significantly decreased, and physical and mental components scores of SF-36 (P=0.018 and P=0.001, respectively) significantly increased after bilateral anodal tDCS stimulation. The GDS score decrease was directly correlated with decrease in PSQI total score (P=0.01), sleep latency sub-score (P=0.002), and sleep disturbance sub-score (P=0.003). In addition, the GDS score decrease was inversely correlated with increasing mental component score of SF-36 (P=0.001), which was directly correlated with an increase in sleep efficiency sub-score (P=0.03) and the physical component score of SF-36 (P=0.0001). CONCLUSIONS Bilateral anodal tDCS stimulation showed potential therapeutic effects in patients with PD in terms of sleep quality and depression level improvement, which together improved mental and physical quality of life in patients with PD.

RESUMO

There is increasing evidence advocating for the causal association between oxidative stress and different neurodegenerative disorders such as Alzheimer disease and epilepsy. We have previously shown that consumption of High-fat diet (HFD) induces oxidative stress, which results in hippocampal neuronal damage hence impairment of learning and memory. This impairment was prevented by antioxidants. The reported damage in the hippocampus caused by oxidative stress following consumption of HFD could alter synaptic transmission in the hippocampus and may increase susceptibility to seizures. The present study was undertaken to determine if chronic consumption of HFD changes susceptibility to chemically induced seizures using the pentylenetetrazol (PTZ) seizure threshold model in rats. In this study, HFD was administered to animals for 6 weeks. Thereafter, the PTZ seizure threshold was measured in control and HFD rats. Different brain regions were analyzed for the levels of oxidative stress biomarkers. Results revealed a significant reduction (50.0 ±â€¯2.5%) in PTZ seizure threshold in rats consuming HFD. This was accompanied by a decrease in the oxidative stress biomarkers and capacity enzymes such as reduced/oxidized glutathione (GSH/GSSG) ratio, glutathione peroxidase (GPx) and catalase activities and increase in oxidized glutathione (GSSG) levels in the hippocampus and cortex regions of the brain of HFD rats. Collectively, current data suggest that prolonged consumption of HFD increases susceptibility to PTZ-induced seizures. Such an effect may be related to HFD- induced oxidative stress in the brain.

RESUMO

Atopic dermatitis is a chronic inflammatory skin disease that arises because of complex environmental, immunological, and genetic interactions. Adipokines are bioactive mediators secreted from adipocytes of white adipose tissue and are known to have a role in body metabolism and regulation of immune responses. Leptin is a proinflammatory adipokine that functions mainly to regulate food intake and energy expenditure. Few studies have implicated adipokines in the pathogenesis of atopic dermatitis. In this study, we investigated the association of three leptin gene polymorphisms: -2548G>A (rs7799039), -188 C/A (rs791620), and A19G (rs2167270), with the incidence of atopic dermatitis. One hundred and sixty-four patients and one hundred and sixty-seven age- and gender-matched controls were genotyped using the polymerase chain reaction-restriction fragment length polymorphism procedure. A significant association was found between rs2167270 and the incidence of atopic dermatitis (P < 0.05). The GG allele was more prevalent in the patients' group with genotype frequency of 38.7%, compared to 26.1% for the control group. No significant differences were found in the genotype distribution or allelic frequency of the other two examined polymorphisms, rs7799039 and rs791620, between atopic dermatitis patients and controls (P > 0.05). The results suggest that rs2167270 might play a role in the pathogenesis of atopic dermatitis.

RESUMO

AIM: To examine BDNF, dopamine, and motor function changes after bilateral anodal transcranial direct current stimulation (tDCS) in patients with Parkinson's disease. METHODS: 20 patients undertook ten sessions of bilateral anodal tDCS stimulation applied simultaneously over FC1/FC2, targeting left and right prefrontal and motor areas. Dopamine and BDNF serum levels, and Movement Disorders Society - Unified Parkinson's Disease Rating Scale part three (MDS-UPDRS-III) total score and disability sub-scores were examined pre/post-tDCS stimulation. RESULTS: BDNF serum level increased significantly and came with significant improvement in motor functions (decrease in MDS-UPDRS-III total score/sub-scores), whereas dopamine level showed no changes. However, there was no significant statistical correlation between the motor functions' improvement and BDNF level increase. CONCLUSION: Bilateral anodal tDCS is a safe stimulation protocol that leads to motor functions' improvement and BDNF serum level increase in patients with Parkinson's disease, however the findings of this feasible study are preliminary and further study is needed.

RESUMO

Atopic dermatitis (AD) is a chronic, relapsing, and inflammatory skin disorder. It is characterized by an inappropriate skin barrier function, allergen sensitization, and recurrent skin infections. Resistin is an adipokine expressed mainly in macrophages and monocytes; it has a role in the inflammatory process and is associated with multiple inflammatory human diseases; however, only few studies linked resistin to atopic dermatitis. This study tested the association between G>A (rs3745367) and C>T (rs3219177) single nucleotide polymorphisms (SNPs) of the RETN gene with atopic dermatitis. In addition, it explored the relationship between serum resistin protein and atopic dermatitis. To achieve objectives of this study, 162 atopic dermatitis patients and 161 healthy participants were recruited in the study. A significant association was detected between rs3745367 and atopic dermatitis with age and gender specificity (p < 0.05), while no significant association between rs3219177 and atopic dermatitis was found (p > 0.05). For the serum resistin levels, a significant decrease was indicated in atopic dermatitis patients compared to healthy subjects (p < 0.05). In conclusion, rs3745367 may play a gender and age-specific role in atopic dermatitis. In addition, the significant decrease in the resistin protein level confirmed this association.

RESUMO

Histamine-2 receptor antagonists are a class of drugs used to treat the acid-related gastrointestinal diseases such as ulcer and gastro-oesophageal reflux disease. Although such drugs, especially ranitidine and famotidine, are still widely used, their effects on semen quality, and hence on male infertility, is still unclear. This MiniReview systematically addresses and summarizes the effect of histamine-2 receptor antagonists (cimetidine, ranitidine, nizatidine and famotidine) on semen quality, particularly, on sperm function. Cimetidine appears to have adverse effects on semen quality. While the effects of ranitidine and nizatidine on semen quality are still controversial, famotidine does not appear to change semen quality. Therefore, additional studies will be required to clarify whether histamine-2 receptor-independent effects of these drugs play a role in semen quality as well as further clinical studies including direct comparison of the histamine-2 receptor antagonists.
