SUMMARY OBJECTIVE: The aim of this study was to evaluate the postpartum hemorrhage, perineal integrity, and breastfeeding results of mothers who underwent oxytocin induction in the first stage of labor in the early postpartum period. METHODS: This single-center observational case–control study was conducted in the obstetric unit of a public hospital in Istanbul. The study sampling included 44 pregnant women who received oxytocin induction (case group) and 44 pregnant women who did not receive oxytocin (control group). The Personal Information Form, LATCH Breastfeeding Assessment Tool, Breastfeeding Self-Efficacy Scale, Redness, Edema, Ecchymosis, Discharge, and Approximation Scale, and Postpartum Hemorrhage Collection Bag were used in data collection, and pad follow-up was carried out. RESULTS: The amount of hemorrhage in the first 24 h of the postpartum period and the mean Redness, Edema, Ecchymosis, Discharge, and Approximation Scale score were significantly higher in the case group. While 47.7% of the oxytocin-induced women had 1st or 2nd, and 11.4% had 3rd or 4th degrees of lacerations, 20.5% of the control group had 1st or 2nd, and 2.3% had 3rd or 4th degrees of lacerations. There was no significant difference between the mean scores of the Breastfeeding Self-Efficacy Scale and LATCH Breastfeeding Assessment Tool in both groups. CONCLUSION: According to the study findings, it was determined that oxytocin induction administered in the first stage of labor increased hemorrhage and perineal trauma in the early postpartum period but did not affect the results of breastfeeding. Clinical Trial Registration Number: NCT04441125.

SUMMARY OBJECTIVE: This study aimed to determine whether maternal cortisol levels affect fetal heart rate patterns in primiparous pregnant women in the third trimester. METHODS: This cross-sectional descriptive study included 400 primiparous pregnant women with uncomplicated pregnancies between November and December 2022. The study included primiparous pregnant women over 18 years old in the third trimester who had not exercised for at least 2 h before the fetal heart rate monitoring and had a healthy pregnancy without consuming any food or drink. Fetuses with decelerating heartbeats and pregnant women who showed uterine contraction and cervical dilation during the fetal heart rate monitoring were excluded from the study. Research data were collected with the data collection form. The fetal heart rate data were collected using a cardiotocograph. At least two accelerations during the 20-min nonstress test period were the basis for diagnosing a reactive nonstress test. About 5 mL of maternal saliva for cortisol measurements was collected before fetal heart rate monitoring. Research data were analyzed with IBM SPSS Statistics for Macintosh, Version 28.0. A p-value of <0.05 was considered significant. RESULTS: There were no significant differences in the comparison of the groups in terms of education and income status, family type, fetal gender, pregnancy planning status, BMI and age averages, or gestational week averages (p>0.05). The number of at least two accelerations required for the diagnosis of reactive NST was also higher in Group 1 (maternal salivary cortisol level ≤24.20). A moderately positive relationship between fetal heart rate and maternal salivary cortisol was observed (r=0.448, p=0.000). In total, 11.9% of the total change in fetal heart rate level is explained by maternal cortisol (R2=0.119). Maternal cortisol increases fetal heart rate level (ß=0.349). CONCLUSION: These findings suggest that stress in primiparous pregnant women with high cortisol levels may influence fetal heart rate patterns. It was revealed that the increase in cortisol level, considered a stress hormone, may be a harbinger of fetal tachycardia.

ABSTRACT The study was conducted to determine the effects of stocking density (SD, 5 or 7 layers/cage) and tarragon (Artemisia dracunculus L.) diet supplementation at four levels (0, 1.2, 6 and 12 g/kg feed) on performance, certain egg characteristics, serum, liver, egg yolk and small intestine bacteria parameters in laying hens. The experiment was carried out over a period of 8 weeks, with 192 Lohman Brown commercial hybrids at 50-w-age. The results showed that an increased SD reduced feed intake (FI; p<0.01) and egg production (p<0.05), but had no effect on the weight gain, feed conversion ratio, damaged egg ratio, egg weight and egg quality (p>0.05) parameters. The supplementation of tarragon to the diet reduced the FI and damaged egg ratio (p<0.01), and improved egg production and FCR (p<0.01). While an increased SD reduced serum total antioxidants (p<0.05), it elevated corticosterone (CORT) and total oxidant serum (TOS) (p<0.05). Tarragon was found to enhance total immunoglobulin (p<0.05), but to decreased the CORT and TOS of the serum (p<0.05). An increased SD raised the malondialdehyde (MDA) in the serum (p<0.001), liver (p<0.05) and yolk (p<0.001). Tarragon supplementation reduced MDA of the serum (p<0.05), liver (p<0.001) and yolk (p<0.001). E. coli and total Mesophilic Aerobic Bacteria counts in the small intestine were raised (p<0.001) with increased SD. Tarragon decreased (p<0.05) mesophilic aerobic bacteria. It was thus found that, tarragon supplementation can be considered generally effective in improving performance parameters, alleviating stress-induced negativities, reducing lipid peroxidation, regulating the immune system and controlling some intestinal microorganisms.

ABSTRACT Objective: The high-grade level of smear acid-resistant bacilli (ARB) positivity has been linked to increased infectiousness in pulmonary tuberculosis (TB). The ability to predict infectiousness is important in the management of the disease. The present study aimed to investigate the relationship between smear results, the clinical features, and the levels of radiological involvement of TB. Methods: A total of 245 cases diagnosed with pulmonary TB were admitted to the study. Data including age, sex, case definition, numbers and characteristics of symptoms, smear results, smear positivity grades, and levels of radiological involvement were recorded. Relations between smear results and other data were determined via cluster tree and regression analysis. Results: The group with only coughing had higher rates of both positive smear and high smear positivity levels (p = 0.014 and p = 0.02, respectively) compared to the group without coughing. Similarly, the groups with moderate or high radiological involvement showed significantly higher rates of both positive smear and high smear positivity level when compared to the group exhibiting low radiological involvement (p < 0.001). Conclusion: Patients with coughing and a moderate to high level of radiological involvement should be closely monitored due to their high-level risk of transmission.

ABSTRACT This study investigated the effects of the addition of Lactobacillus reuteri E81 (LRE) into rations of chukar partridges (Alectoris chukar) fed under heat stress (HS) conditions on fattening performance and meat quality. This study included 256 chukar partridges aged 1 day. The study comprised an adaptation period of 7 days and a fattening period of 35 days and included 8 different groups with 32 animals in each group. Each group was further divided into four subgroups with eight animals in each subgroup. At the end of the study, the best results in terms of fattening performance in the non-HS groups were obtained in the LRE 600 ppm group and in the HS groups, SLRE 200 ppm had the best effect on average live weight and average live weight increase, whereas SLRE 400 ppm had the best effect on FCR (p<0.05). The analysis of the samples collected from chukar partridges on day 21 showed that, there was no effect on the colour parameters and Thiobarbituric acid reactive substances (TBARS) level in the LRE in the HS and non- HS groups, whereas the meat pH level decreased in the SLRE 400 ppm group (p<0.05). The analysis of the samples collected on day 42 showed that there was no effect on colour parameters in the HS and non-HS groups. TBARS level decreased at the dose of LRE 200 ppm in the non-HS group, and the meat pH level decreased in both HS and non-HS groups (p<0.05).

ABSTRACT Ninety-six 28-week-old Lohmann White laying hens were utilized to test the antioxidant effects of flavonoids (hesperidin, naringin, and quercetin at 0.5 g/kg diet) during an 8-wk experimental period. At the end of the experiment blood samples were collected to determine total protein, cholesterol, and malondialdehyde (MDA) serum levels as well as activities of glutathione reductase (GR), glutathione peroxidase (GSH-Px), glutathione-S-transferase (GST), and superoxide dismutase (SOD) and level of glutathione (GSH) in erythrocyte lysates. Data were analyzed using one-way ANOVA. Naringin supplementation did not alter serum cholesterol concentration, whereas hesperidin and quercetin supplementations decreased serum cholesterol concentration. Naringin and quercetin supplementations did not affect serum protein concentration. All flavonoids decreased MDA concentration as well as increased GSH-Px, GR, GST, and SOD activities and GSH level, being quercetion superior to hesperidin and naringin. In conclusion, flavonoids, especially quercetin, exert antioxidant activity, which may help improve wellbeing when laying hens are exposed to stressors.

A total of 32 Wistar rats were divided into four equal groups: (I) sham, (II) ischemia, (III) reperfusion and (IV) Potentilla fulgens. In groups I and II, ovary torsion was not performed and no drug was administered. In group III, 1 h of ischemia and 2 h of reperfusion were performed and no drug was given. Group IV received 400 mg/kg/day Potentilla fulgens intraperitoneally 5 days before Ischemia-reperfusion. All the parameters were observed to be significantly decreased (P<0.05) in all the experimental groups compared to the control group. In the sections of the ischemia-reperfusion group, degeneration of epithelium, dilation of blood vessels were observed. Potentilla fulgens administration reduced the morphological changes by induced I/R; in particular, infiltration, hemorrhage and vascular dilatation were decreased. Potentilla fulgens application during torsion, it plays an important role in maintaining the epithelial structure with E-cadherin expression. We suggest that PECAM-1(CD31) are a regulator of the microvascular response of the tubal mucosa.

Un total de 32 ratas Wistar fueron divididas en cuatro grupos: (I) Sham, (II) isquemia, (III) reperfusión y (IV) Potentilla fulgens. En los grupos I y II, no se realizó la torsión de ovario y ni se administró ningún tipo de fármaco. En el grupo III, se produjo isquemia por 1 h seguido de reperfusión por 2 h (I/R), sin administracion de fármacos. El grupo IV recibió 400 mg/kg por día de Potentilla fulgens vía intraperitoneal durante cinco días previo al protocolo de isquemia-reperfusión. Se observó que todos los parámetros disminuyeron significativamente (P <0,05) en todos los grupos experimentales en comparación con el grupo control. En las secciones del grupo de isquemia-reperfusión, se observó degeneración del epitelio y dilatación de los vasos sanguíneos. La administración de Potentilla fulgens reduce los cambios morfológicos inducidos por I/R; en particular, la infiltración, la hemorragia y la dilatación vascular. La aplicación de Potentilla fulgens durante la torsión, desempeña un papel importante en el mantenimiento de la estructura epitelial con la expresión de E-cadherina. Sugerimos que PECAM-1 (CD31) es un regulador de la respuesta microvascular de la mucosa tubárica.

Objetivo:Comparar a eficácia de bloqueios dos nervos ílio-hipogástrico/ilioinguinal feitos com a técnica guiada por ultrassom e a de marcos anatômicos para o manejo da dor no pós-operatório em casos de herniorrafia inguinal em adultos.Métodos:Foram randomicamente divididos 40 pacientes, estado físico ASA I-II, em dois grupos iguais: nos grupos AN (técnica de marcos anatômicos) e US (técnica guiada por ultrassom), o bloqueio dos nervos ílio-hipogástrico/ilioinguinal foi feito com 20 mL de levobupivacaína a 0,5% antes da cirurgia com as técnicas especificadas. Escore de dor na avaliação pós-operatória, tempo de primeira mobilização, tempo de internação hospitalar, escore de satisfação com a analgesia no pós-operatório, efeitos colaterais induzidos por opiáceos e complicações relacionadas ao bloqueio foram avaliados durante 24 horas de pós-operatório.Resultados:Escores EVAem repouso na sala de recuperação e todos os valores clínicos durante o acompanhamento foram significativamente menores no grupo ultrassom (p < 0,01 ou p < 0,001). Escores EVA em movimento na sala de recuperação e todos os valores clínicos durante o acompanhamento foram significativamente menores no grupo ultrassom (p < 0,001 em todos os tempos avaliados). Enquanto os tempos de internação e da primeira mobilização foram significativa-mente menores, os índices de satisfação com a analgesia foram significativamente maiores no grupo ultrasom (p<0,05, p< 0,001, p< 0,001, respectivamente).Conclusão:De acordo com o nosso estudo, o bloqueio dos nervos ílio-hipogástrico/ilioinguinal guiado por US em herniorrafias inguinais em adultos proporciona uma analgesia mais eficaz e maior satisfação com a analgesia do que com a técnica de marcos anatômicos. Além disso, pode-se sugerir que a observação das estruturas anatômicas com a US pode aumentar o sucesso do bloqueio e minimizar as complicações relacionadas ao bloqueio.

Objectives:The purpose of this study is to compare the efficacy of iliohypogastric/ilioinguinal nerve blocks performed with the ultrasound guided and the anatomical landmark techniques for postoperative pain management in cases of adult inguinal herniorrhaphy.Methods:40 patients, ASA I-II status were randomized into two groups equally: in Group AN (anatomical landmark technique) and in Group ultrasound (ultrasound guided technique), iliohypogastric/ilioinguinal nerve block was performed with 20 ml of 0.5% levobupivacaine prior to surgery with the specified techniques. Pain score in postoperative assessment, first mobilization time, duration of hospital stay, score of postoperative analgesia satisfaction, opioid induced side effects and complications related to block were assessed for 24 h postoperatively.Results:VAS scores at rest in the recovery room and all the clinical follow-up points were found significantly less in Group ultrasound (p < 0.01 or p < 0.001). VAS scores at movement in the recovery room and all the clinical follow-up points were found significantly less in Group ultrasound (p < 0.001 in all time points). While duration of hospital stay and the first mobilization time were being found significantly shorter, analgesia satisfaction scores were found significantly higher in ultrasound Group (p < 0.05, p < 0.001, p < 0.001 respectively).Conclusion:According to our study, US guided iliohypogastric/ilioinguinal nerve block in adult inguinal herniorrhaphies provides a more effective analgesia and higher satisfaction of analgesia than iliohypogastric/ilioinguinal nerve block with the anatomical landmark technique. Moreover, it may be suggested that the observation of anatomical structures with the US may increase the success of the block, and minimize the block-related complications.
