The effect of mindfulness-based childbirth education intervention on fear of childbirth: systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to describe the effect size of mindfulness-based childbirth education on the fear of childbirth. METHODS: In this study, the meta-analysis method, one of the methods of synthesising quantitative research, was used. EBSCO, PubMed, Google Scholar, WOS, and CINAHL databases were used to determine the studies to be included in the meta-analysis. The keywords such as "mindfulness", "fear of childbirth", "mindfulness-based childbirth", "mindfulness education" and "childbirth" were searched in the international literature. Four experimental studies published between 2013 and 2022 that aimed to determine the effect of mindfulness-based childbirth education on the fear of childbirth, had a full text available and met the inclusion criteria, were included in the study. RESULTS: On the analysis of the data, mindfulness-based childbirth education was found to be effective in reducing the fear of childbirth (standard mean difference [SMD]=0.117, 95%CI: -1.049: -0.419, p<0.001, I2=36.98%). The results of this meta-analysis indicated that mindfulness-based education provided to pregnant women was found to be effective in reducing the fear of childbirth. CONCLUSION: Mindfulness-based childbirth education is considered to be used as an effective non-pharmacological midwifery and nursing intervention in reducing the fear of childbirth in pregnant women. This review was preregistered on PROSPERO (Ref No: CRD42022316472).

Effects of intrauterine device use on attack frequency and severity in woman of reproductive age with familial Mediterranean fever.

AIM: Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disease in the world. There are known triggers to initiate an FMF attack, yet potential effects of intrauterine devices (IUD) in women of reproductive age have not been evaluated before. METHOD: Consecutive female patients with FMF who ever used IUD over the age of 18 were enrolled. Female patients with FMF were sub grouped according to the type of IUD they use. FMF attack frequency, severity, duration, presence of dysmenorrhea, severity of dysmenorrhea, having attacks during menstruation before and after IUD use were questioned. Demographic and clinical data were collected from hospital database. RESULTS: When all patients with IUD use were evaluated, it was found that the frequency of attacks increased after IUD insertion at 3rd and 12th months (median [min-max] attack frequency at 3rd month, 1 (0-3) vs 1 (0-6), p = 0.002, median [min-max] attack frequency at 12th month, 2 (0-12) vs 3.5 (0-18), p = 0.028). Attack severity measured by VAS pain was also significantly increased. Attack duration and menstrual pain was similar before and after IUD use. Attack frequency at 3rd and 12th months, attack severity and menstrual pain was all increased significantly in Cu-IUD users, whereas none of these parameters deteriorated in LNG-IUD group. CONCLUSION: IUD use, especially Cu-IUD, may increase the frequency and severity of attacks in female patients with FMF. Clinicians may benefit from considering LGN-IUD if IUDs are preferred as contraception in women of childbearing age with FMF.

Microbial membrane transport proteins and their biotechnological applications.

Because of the hydrophobic nature of the membrane lipid bilayer, the majority of the hydrophilic solutes require special transportation mechanisms for passing through the cell membrane. Integral membrane transport proteins (MTPs), which belong to the Major Intrinsic Protein Family, facilitate the transport of these solutes across cell membranes. MTPs including aquaporins and carrier proteins are transmembrane proteins spanning across the cell membrane. The easy handling of microorganisms enabled the discovery of a remarkable number of transport proteins specific to different substances. It has been realized that these transporters have very important roles in the survival of microorganisms, their pathogenesis, and antimicrobial resistance. Astonishing features related to the solute specificity of these proteins have led to the acceleration of the research on the discovery of their properties and the development of innovative products in which these unique properties are used or imitated. Studies on microbial MTPs range from the discovery and characterization of a novel transporter protein to the mining and screening of them in a large transporter library for particular functions, from simulations and modeling of specific transporters to the preparation of biomimetic synthetic materials for different purposes such as biosensors or filtration membranes. This review presents recent discoveries on microbial membrane transport proteins and focuses especially on formate nitrite transport proteins and aquaporins, and advances in their biotechnological applications.

A single-center rheumatology experience of sarcoidosis: observations from 70 patients.

BACKGROUND: The aim of this study is to determine the demographic, clinical and laboratory characteristics of the patients who followed up with the diagnosis of sarcoidosis, to investigate the distribution frequency of rheumatological findings and to examine the disease management from the perspective of rheumatology. METHODS: Patients who were followed up with the diagnosis of sarcoidosis in the rheumatology clinic of Ankara City Hospital between November 2019 and November 2022 were evaluated. Demographic, clinical, radiological, serological, laboratory, and histopathological findings, and rheumatological, systemic, and locomotor system examination findings of the patients were obtained from the medical data registered in the hospital. RESULTS: A total of seventy sarcoidosis patients (48.98 ± 11.78 years, %75 female) were included in the study. Joint involvement was observed in 64.3% of cases, skin involvement in 48.6% of cases, and ocular involvement in 25.7% of cases. The ankle was the most frequently involved joint, followed by the knee and small joints in the foot. Corticosteroids were the most used therapeutic agent, and pulmonary and joint findings were the most common reasons for starting treatment. CONCLUSIONS: Sarcoidosis is a disease that mimics many diseases, misdiagnosis and treatment should be avoided with a good and fast differential diagnosis. Clinicians, especially rheumatologists, should remember sarcoidosis more frequently and keep it in mind in the differential diagnosis.

Comparison of ion selectivities of nitrite channel NirC and water channel aquaporin.

nirC gene coding for the nitrite channel of E. coli K12 was cloned into the pET28a vector and expressed in E. coli BL21 cells. 28.5 kDa NirC monomer was purified from membrane components of E. coli. Selectivity of NirC for different ions including nitrite, nitrate, sulfate, formate, and acetate anions, and a divalent cation, magnesium, was compared with that of bacterial aquaporin from Halomonas elongata. Water and ion permeability values were determined by measuring the light scattering rates of proteoliposomes containing NirC and aquaporins during their water loss and gain. NirC shows a selective permeability to nitrite and is more resistant to the entry of other anions as compared to aquaporin. The single channel permeability of NirC for nitrite is about 10-fold that of a single aquaporin channel. Both aquaporin and NirC channel proteins were impermeable to MgCl2 and (NH4)2SO4 and their permeability to other tested ions was remarkably lower as compared to nitrite ions. The study also presents the 3D model and channel characteristics of NirC. The translocation channel of E. coli NirC is determined to be larger, and its length is shorter than aquaporin channels. Although the NirC channel throat is more hydrophobic than aquaporin, its water permeability is almost equal to that of aquaporin. The hydrophobic nature of the NirC channel might play an important role in the selective permeability of the channel for nitrite ions.

Nitrite is reduced by nitrite reductase NirB without small subunit NirD in Escherichia coli.

The assimilatory nitrite reductase enzyme NirB and small subunit NirD genes encoded in nir operon in Escherichia coli were cloned into the pET28a vector, and the recombinant enzyme was characterized for the first time. Docking of NirB with NirD, NADH, NO2-, NO3-, and CHO2- was performed using docking modeling programs. Methyl viologen and sodium dithionite were used as electron couples, and the amount of reduced nitrite was measured to calculate enzyme activity. NirB is the main enzyme and shows high activity with or without NirD. However, the inclusion of NirD into the enzyme solution at a ratio of 1NirD:2NirB resulted in 10% higher nitrite reductase activity. The enzyme tends to aggregate in the absence of ß-mercaptoethanol, which causes the conversion of tetrameric NirB to monomeric form, and the NirB enzyme shows its highest activity in monomeric form. The optimum temperature for enzyme activity was 37 °C and the optimum pH was found to be 7.0. Km and Vmax values of NirB were calculated as 9833 µM and 416.67 µmol NO2- reduced min-1 mg-1. Enzyme activity decreased by 55% and 50% in the presence of 100 mM nitrate and formate, respectively. The presence of 25 mM Cd2+ protected the enzyme at room temperature and the enzyme showed 10% higher activity in the presence of cadmium.

The Effect of Solution Focused Group Psychoeducation Applied to Schizophrenia Patients on Self-Esteem, Perception of Subjective Recovery and Internalized Stigmatization.

The study examined the effect of Solution-Focused Group Psychoeducation on self-esteem, subjective perception of recovery, and internalized stigma among patients with schizophrenia 39 patients with schizophrenia were recruited based design of the randomized control-group with pretest and posttest. The patients completed the "Rosenberg Self-Esteem Scale (RSES)", "Subjective Recovery Assessment Scale (SubRAS)", and "Internalized Stigma of Mental Illness (ISMI) Scale" in pretest and posttest. After the psychoeducation, ISMI scores decreased in the intervention group (p < 0.001) but increased in the control group (p = 0.599). The posttest RSES score was lower in the intervention group compared to the control group (p = 0.001). A statistically significant difference was found between the pretest and posttest SRAS scores of the intervention group when compared to the control group (p = 0.018). After the psychoeducation, intervention group' self-esteem and subjective perception of recovery increased, while the severity of internalized stigma decreased.

A single-center COVID-19 vaccine experience with CoronaVac and BNT162b2 in familial Mediterranean fever patients.

AIM: To determine frequency of adverse events and attacks related to vaccination in recipients of CoronaVac and BNT162b2 in familial Mediterranean fever (FMF) patients, and to search whether history of prior COVID-19 or a booster dose increases occurrence of adverse events/attacks. METHODS: FMF patients were surveyed for administration of any COVID-19 vaccine and vaccine-related adverse events or FMF attacks. Demographic, clinical, vaccine-related data, history of COVID-19 infection before or after vaccination, adherence to FMF treatment during vaccination were collected. RESULTS: A total of 161 vaccinated FMF patients were included. Ninety-three patients out of 161 had reported suffering from an adverse event/attack after a vaccine dose. There were 54.7% of BNT162b2 recipients who reported any adverse event after any vaccine dose in comparison to 29.9% of CoronaVac recipients (P < .001). There were 22.2% of BNT162b2 recipients who reported suffering from a FMF attack within 1 month after vaccination in comparison to 19.4% of CoronaVac recipients (P = .653). When patients with or without adverse event/attack were compared, no significant differences were observed in means of demographics, comorbid diseases, disease duration, total vaccine doses, or treatments adhered to for FMF. Rates of adverse events/attacks were similar between patients with and without prior COVID-19. In booster recipients, adverse events/attacks were most frequent after the booster dose. CONCLUSIONS: A considerable number of FMF patients suffered from vaccine-related adverse events/attacks, particularly with BNT162b2. No serious events or mortalities due to vaccination were detected. Demographics, clinical characteristics and prior history of vaccination did not significantly affect these results. We observed an increased rate of adverse events/attacks with booster dose administration.

Thyroid Volume in Systemic Sclerosis Patients: A Cross-Sectional Study.

INTRODUCTION: Systemic sclerosis (SSc) is a multisystemic disease. Thyroid involvement in systemic sclerosis is an overlooked issue. Our study aimed to evaluate the decreased thyroid volume in SSc. Also, we aimed to show the relationship between patients' thyroid volume and clinical and laboratory parameters. METHOD: This was a single-center, cross-sectional study. Eighty-six patients were included in the study. A radiologist evaluated patients' thyroid volumes by ultrasonography. Demographic and clinical characteristics of the patients were recorded. Skin thickness was evaluated by the modified Rodnan skin score (mRSS) and the disease severity by the Medsger severity score (MSS). Findings were analyzed statistically. RESULTS: Thyroid volume was in the atrophic range in 53.5% of the patients. There was a significant negative correlation between thyroid volume and mRSS, MSS, and disease duration. Logistic regression analysis showed that mRSS and disease duration were risk factors for thyroid atrophy. CONCLUSIONS: Many studies point out that thyroid autoantibodies are a cause of thyroid dysfunction in patients with SSc. However, in most of these studies, thyroid volume was not evaluated. As a result of our study, we saw that the major cause of thyroid dysfunction in our SSc patients was thyroid atrophy. Also, we observed that thyroid atrophy was more common in patients with interstitial lung disease. We would like to draw attention to the fact that thyroid dysfunction and volume changes increase with the disease's duration and severity in systemic sclerosis.

The evaluation of nailfold capillaroscopy pattern in patients with fibromyalgia.

OBJECTIVES: This study aims to evaluate nailfold capillaroscopic pattern in patents with fibromyalgia and to assess the relation of capillaroscopic parameters with clinical variables and disease-related measures. PATIENTS AND METHODS: This cross-sectional, case-control study included 60 participants (4 males, 56 females; mean age: 44.0±8.2 years; range, 26 to 64 years) between August 2019 and November 2019. All participants were divided into two groups as the primary fibromyalgia group (n=30) who met the 2016 modified American College of Rheumatology Diagnostic Criteria for Fibromyalgia and the control group (n=30) consisting of age- and sex-matched healthy individuals. Nailfold capillaroscopy was performed by a digital microscope under a magnification of 200X. Capillary density, capillary loop diameter, number of dilated, giant and neoangiogenic capillaries, capillary shape, number of avascular areas, micro-aneurysms and micro-hemorrhages were evaluated by an assessor who was blind to the group allocation. In the fibromyalgia group, Widespread Pain Index, Symptom Severity Scale scores, and Fibromyalgia Severity scores were calculated. Health status and presence of benign joint hypermobility syndrome (BJHS) were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and revised Brighton criteria, respectively. RESULTS: Of the capillaroscopic parameters, the mean capillary loop diameter, number of micro-aneurysms, avascular areas, and neoangiogenic capillaries were significantly higher in the patient group compared to the controls (p<0.001, p=0.016, p=0.038, and p=0.04, respectively). Nailfold capillaroscopic findings did not significantly differ between the patients with (n=16) and without concomitant BJHS (n=14). Of the disease-related measures, only FIQ score showed a weak correlation with the number of dilated capillaries (p=0.324). CONCLUSION: Patients with fibromyalgia have distinct capillaroscopic patterns than healthy population. Capillaroscopic features, in general, are not related to clinical variables and disease-related measures.

Arterial evaluation of systemic sclerosis patients with Doppler ultrasound: What did we find?

AIM: The aim of this study was to detect macrovascular findings in systemic sclerosis (SSc) by means of color Doppler ultrasonography (CDUS) and to evaluate the relationship between the laboratory and clinical findings in the setting of the disease. METHODS: This was a cross-sectional study. Eighty-eight patients were included in the study. CDUS examinations of the bilateral carotid, vertebral, and peripheral arteries were performed. The presence of macrovascular involvement was investigated and recorded, and its relationships with the clinical, laboratory, and cardiovascular risk factors were evaluated. RESULTS: An atheromatous plaque was found in 67.7% of the 1936 arteries examined by CDUS. Of these 1936 arteries, 37.4% demonstrated a narrowing of the intraluminal diameter. On the other hand, the carotid intima-media thickness (CIMT) was found to have increased in 55.7% of the patients. This increase was found to be statistically correlated with disease duration, the modified Rodnan Skin Thickness Score, and the Medsger Disease Activity Score. But no relation existed with the disease subtype, age, or cardiovascular risk factors. Arterial occlusion was detected in 10 patients. An association was found between the CIMT values and arterial occlusion. CONCLUSIONS: In this study, we examined the arteries by means of CDUS, and we detected structural alterations in the peripheral and carotid arteries. We witnessed that these macrovascular changes had a close association with certain features of SSc. We think there is a need for broader prospective studies in order to evaluate the contribution of these factors to the macrovascular changes stated in the article.

Effect of psychological care given to the women who underwent hysterectomy before and after the surgery on depressive symptoms, anxiety and the body image levels.

This study was conducted for the purpose of evaluating the effect of the psychological care given to women before and after hysterectomy surgery on depression levels, anxiety and body image. This experimental study was conducted in the gynecological oncology surgery clinic of Samsun Education and Research Hospital in Turkey between the dates of January 2018 and June 2018. Those who meet the sample selection criterion and agreed to participation to the study among the women who were admitted to the clinic for hysterectomy were assigned randomly to the experimental and control groups. 42 women in total including 21 women in each of experimental and control groups formed the sample of the study. The effect of the psychological care was evaluated through Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI) and Body Catherix Scale (BCS). The evaluation measurements were conducted as pre-test, post-test and follow-up (2-months post-test). The BDI and STAI scores of the women who receive psychological care have decreased and their BPS scores have increased. On the contrary, BDI and STAI scores of the women who receive psychological care in the experimental group have increased and their BCS scores have decreased. These findings show that psychological care has positive effects on depressive symptoms, anxiety and the body image in the women who underwent hysterectomy.IMPACT STATEMENTWhat is already known on this subject? Having a hysterectomy impacts a woman's life in a significant manner. As such, deciding to undergo a hysterectomy is a difficult process for women, especially from a psychological perspective. Following a hysterectomy, women commonly experience changes in body perception, such as perceiving the body as different, feeling disabled, feeling hollow, believing they are different than other women and feeling that their body is attracting notice. The literature reports that women perceive themselves as different, alienated, impaired and changed after a hysterectomy and that they have difficulty making contact with the environment; furthermore, the more changes in body perception increase, the more depression increases.What the results of this study add? This study revealed that psychological care given to women before and after undergoing a hysterectomy decreases anxiety and increases positive body perception. For this reason, psychological care for women undergoing hysterectomies should be part of routine nursing care and should be started upon the hospitalisation of the patient.What are the implications of these findings for clinical practice and/or further research? The findings of this study indicate that after a hysterectomy, women experience not only physiological disease symptoms but also psychological problems. Therefore, women who have undergone or will undergo a hysterectomy also have psychological needs. Further study is suggested to determine what can be done with a professional team to meet the demands for psychological care.

Rutin ameliorates methotrexate induced hepatic injury in rats.

PURPOSE: To investigate the possible protective effect of rutin on methotrexate induced hepatotoxicity in rats. METHODS: Twenty-two rats were divided into three experimental groups; Control-saline, Mtx, Mtx+Rutin. Hepatic tissue was taken for histological assessment and biochemical assays. Oxidative stress parameters malondialdehyde (MDA), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) were investigated. Liver markers aspartate aminotransferase (AST), alanine aminotransferase (ALT) were analyzed in serum. RESULTS: Mtx+Rutin group showed lower histological injury compared to Mtx group, MDA and ALT levels were increased, while SOD and GSH-Px were decreased in Mtx group compared with Control-saline group. MDA and ALT levels were increased, while SOD and GSH-Px were decreased in Mtx group, compared with Mtx +Rutin group. Serum AST levels were similar among the groups. CONCLUSION: Rutin may be a potential adjuvant drug to reduce the hepatic side effects observed during Mtx therapy for various clinical conditions.

Histological evaluation of the changes in temporomandibular joint capsule and retrodiscal ligaments following autologous blood injection.

INTRODUCTION: In recent years injection of autologous blood into the temporomandibular joint (TMJ) has been reintroduced as a treatment of chronic recurrent TMJ dislocation. The effects of this treatment on components of the TMJ is not fully understood. The purpose of this article is to evaluate the effects of autologous blood on TMJ capsule and the retrodiscal ligament. MATERIAL AND METHODS: A total of 16 healthy adult country bred pig were used in this study. Autologous blood were injected into the upper joint space (4 ml) and around the capsule of TMJ unilaterally (1 ml). This procedure was then repeated on the opposite side only by using 5 ml of 0.9% saline. TMJ capsules and retrodiscal ligaments were examined four weeks following the injections. RESULTS: Histological examination of TMJs injected with autologous blood revealed fibrotic changes in 81.25% of the retrodiscal ligaments and 56.25% of the capsular areas. Whilst no changes were seen in the retrodiscal ligaments nor in the capsules of TMJs injected with saline alone. CONCLUSION: There is little published clinical data on the use of autologous blood injection and as such the mechanism of action is still unclear. The rate of induction of fibrosis within the retrodiscal ligaments in this study were similar to previously reported studies and case series. However, further studies to evaluate the mechanism of this safe and simple technique are needed.

The efficacy of ozone therapy in experimental caustic esophageal burn.

INTRODUCTION: Ozone has been proposed as an antioxidant enzyme activator, immunomodulator and cellular metabolic activator. This study was designed to investigate the efficacy of ozone therapy in the prevention of esophageal damage and stricture formation developed after esophageal caustic injuries in the rat. MATERIALS AND METHODS: Forty-five rats were allocated into three groups; sham-operated, un-treatment and treatment groups. Caustic esophageal burn was created by instilling 15% NaOH in the distal esophagus. The rats were left untreated or treated with 1 mg/kg/day ozone intraperitoneally. All rats were sacrificed at 28 days. Efficacy of the treatment was assessed by measuring the stenosis index (SI) and histopathologic damage score, and biochemically by determining tissue hydroxyproline content (HP), superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA) and protein carbonyl content (PCC) in esophageal homogenates. RESULTS: Whereas seven (47%) rats died in the un-treatment group, all rats in the sham-operated and the treatment group survived during the study. SI, the histopathologic damage score, was significantly lower in the ozone-therapy group than the un-treatment group. HP levels were significantly higher in the un-treatment group than the group treated with ozone. Caustic esophageal burn increased MDA and PCC levels and also decreased SOD and GPx enzyme activities. In contrast, ozone therapy decreased the elevated MDA and PCC levels and also increased the reduced SOD and GPx enzyme activities. CONCLUSION: Ozone has a preventive effect in the development of fibrosis by decreasing tissue damage and increasing the antioxidant enzyme activity in an experimental model of corrosive esophageal injury.

Effect of 3-amino benzamide, a poly(adenosine diphosphate-ribose) polymerase inhibitor, in experimental caustic esophageal burn.

INTRODUCTION: The enzyme poly(adenosine diphosphate-ribose) polymerase affects the repair of DNA in damaged cells. However, its activation in damaged cells can lead to adenosine triphosphate depletion and death. This study was designed to investigate the efficacy of 3-amino benzamide (3-AB), a poly(adenosine diphosphate-ribose) polymerase inhibitor, on the prevention of esophageal damage and stricture-formation development after esophageal caustic injuries in rat. MATERIALS AND METHODS: Forty-five rats were allocated into 3 groups: sham-operated, untreated, and treated groups. Caustic esophageal burn was created by instilling 15% NaOH to the distal esophagus. The rats were left untreated or treated with 3-AB 10 mg/kg per day intraperitoneally. All rats were killed on the 28th day. Efficacy of the treatment was assessed by measuring the stenosis index and histopathologic damage score and biochemically by determining tissue hydroxyproline content, superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA), and protein carbonyl content (PCC) in esophageal homogenates. RESULTS: Treatment with 3-AB decreased the stenosis index and histopathologic damage score seen in caustic esophageal burn rats. Hydroxyproline level was significantly higher in the untreated group as compared with the group treated with 3-AB. Caustic esophageal burn increased MDA and PCC levels and also decreased SOD and GPx enzyme activities. On the contrary, 3-AB treatment decreased the elevated MDA and PCC levels and also increased the reduced SOD and GPx enzyme activities. CONCLUSION: 3-Amino benzamide has a preventive effect in the development of fibrosis by decreasing tissue damage and increasing the antioxidant enzyme activity in an experimental model of corrosive esophagitis in rats.
