Objective. In this study, we have assessed sympathovagal imbalance (SVI) by spectral analysis of heart rate variability (HRV) that contributes to the genesis of early-onset PIH.Methods. Body mass index (BMI), basal heart rate (BHR), blood pressure (BP) and HRV indices such as LFnu, HFnu, LF-HF ratio, mean RR, SDNN and RMSSD were assessed in normal pregnant women (Control group) and pregnant women having risk factors for PIH (Study group) at all the trimesters pregnancy. Retrospectively, those who did not develop PIH (Study group I) were separated from those who developed PIH (Study group II). Study group II was subdivided into early-onset and late-onset PIH. Sympathovagal balance (LF-HF ratio) was correlated with BMI, BHR and BP.Results. LF-HF ratio was significantly high in study group II compared to study group I and control group, and in early-onset PIH group compared to the late-onset category at all the trimesters of pregnancy, which was significantly correlated with BHR and BP. Alteration in HFnu in early-onset category was more prominent than the alteration in LFnu.Conclusion. Though the SVI in PIH is contributed by both sympathetic overactivity and vagal withdrawal, especially in early-onset type, SVI is mainly due to vagal inhibition.

We represent the results of the combined method of treatment and prevention of miscarriage in women with a multiple pregnancy and a high risk of the threat of termination the pregnancy because of using the obstetric unloading pessaries, combined with micronized progesterone. The efficiency of this method of treatment is evidenced by the rapid elimination of clinical symptoms of threatened abortion, accelerating the regression of ultrasound markers, reducing the number of complications in of pregnant women and reducing the time of their stay in hospital.Goal: To evaluate the effectiveness of the handling the obstetric pessary in combination with micronized progesterone at women with multifetal pregnancy and a high risk of miscarriage.Materials and methods. We analyzed 120 cases of multifetal pregnancies with signs of miscarriage within the terms from 16 to 28 weeks. The first group of the examined women was: 40 pregnant women with twins and signs of miscarriage, who in the scheme of treatment and prophylactic measures were offered to use the unloading obstetric pessaries in combination with continuous therapy by natural micronized progesterone until 36 weeks of pregnancy. The second group included 40 pregnant women with twins, who were laid seam on the cervix because of istmicocervical insufficiency and were applied short-term courses of therapy by gestagens. The control group comprised 40 pregnant women with twins at the age of 16-28 weeks of pregnancy who were conducted the therapy about the threat of miscarriage according to the current clinical protocols (Order of the Ministry of Health of Ukraine No. 624). It was carried out the analysis of the course of pregnancy, childbirth, the postpartum period and the state of neonatal adaptation in the surveyed groups.Results of the research and their discussion. In the first group, urgent childbirth occurred in 34 (85%) cases, in group II in 29 (72.5%) cases, in control group – in 25 (62.5%) cases. Cesarean delivery was performed in 7 (17.5%) patients of group I pregnant women, in 9 (22.5%) of group II patients and in 11 (27.5%) in the pregnant group. When studying the state of neonatal adaptation of newborns in the examined groups, the following results were obtained. The average weight of the newborns in group I was 3245 ±280 g, in group II 2865 ±365 g, in the control group - 2975 ±325 g (p>0.05). The evaluation of the state of newborns on the Apgar scale, respectively at the 1st and 5th minutes, was respectively: in newborns of the I group, 7.5 ± 1.4 and 8.4 ± 1.3 points, in group II - 7.3 ± 1.6 and 8.2 ± 1.1 points, in the control group – 7.2 ± 1.6 and 8.6 ± 1.2 (р 1-р 2> 0.05).Conclusions. Comprehensive prophylaxis of non-pregnancy in multiple pregnancies, combining the use of a traumatic cardiac cervix with the help of unloading obstetric pussies with progesterone preparations, allows prolonging pregnancy, preventing the development of prematurity, contributes to the improvement of perinatal indicators.

Aims & Objectives: To study the effect of epidural analgesia (EA) in labour on the rate of instrumental deliveries Study Design: Clinical Trial / Case Control study. Study Settings: Labour ward of Jinnah Hospital, Lahore during one year period from July 2002 to June 2003. Patients and Methods: One hundred women in labor at term were divided into two equal groups. Group-I comprised of those women who were provided with epidural analgesia while group-II consisted of those women who had labour without the block. The anesthetist provided epidural analgesia using 0.125% bupivacaine and the obstetrician or midwife gave intermittent top-ups. Main Outcome Measures: The main outcome measures were the effect of epidural analgesia on the duration of second stage of labor and the rate of instrumental deliveries. The data was collected on a pre-designed proforma and was analyzed on computer software (SPSS). Ratio and proportions were calculated and Chi-square test was used to check significant association between the groups. P<.05 was considered statistically significant. Results: Gestational age, gravidity, duration of first stage of labour, and fetal outcome were comparable between the two groups. There was prolongation of second stage of labour (P < 0.05). 30% of the parturient in the group with epidural analgesia had second stage of <1 hour while there were 84 % of women in the control group who had second stage of <1 hour. 66% of the women in group I (EA) had duration of second stage of 1-2hours while in group-II 16% of women delivered in the same period. 4% of the women in the study group had second stage of >2hours while there was none (0.0%) who took >2hours in the control group. There was an increased rate of instrumental deliveries in patients with epidural analgesia (P<0.05). 40% of women had instrumental deliveries in the study group as compared to 10 % in the control group. Patient satisfaction was excellent among parturient given EA, 94 % of the parturient being very satisfied. Conclusion: Epidural analgesia along with an experienced anesthetist, a dedicated obstetrician and a trained midwife can convert the painful labour into a less stressful event. Although it prolongs the second stage of labour and increases the rate of instrumental deliveries yet its advantages of pain free labour, better psychological outcome and no significant complications outweigh these drawbacks.

Objective. To explore the effect of mobile Internet on attitude and self-efficacy of patients with coronary heart disease (CHD) diagnosed by 12-lead Holter ECG. Methods. The clinical data of 62 patients with CHD who underwent routine ECG examination (control group I) and 12-lead dynamic electrocardiogram (control group II) in our hospital (June 2017–December 2020) were retrospectively analyzed, and the clinical data of another 62 patients with CHD who received 12-lead Holter ECG examination combined with mobile Internet in our hospital at the same time (study group) were retrospectively analyzed. The clinical observation indexes of the three groups were compared. Results. No obvious difference in general data among groups ( P > 0.05 ). Compared with the control group I, the positive detection rate (PDR) of the study group and the control group II was obviously higher ( P < 0.05 ), and the PDR of the study group was obviously higher than that of the control group II, without remarkable difference between both groups ( P > 0.05 ). Compared with the control group, the scores of CAS-R of the study group were obviously higher ( P < 0.05 ), and self-efficacy of daily life, health behaviors, medication compliance, and compliance behavior of the study group was obviously better ( P < 0.05 ). The diagnostic efficacy was derived by ROC curve analysis, 12-lead Holter ECG combined with mobile Internet + routine ECG > 12-lead Holter ECG combined with mobile Internet > 12-lead Holter ECG > routine ECG. Conclusion. Compared with the routine ECG, the sensitivity of 12-lead Holter ECG in the diagnosis of CHD is conspicuously higher. Meanwhile, 12-lead Holter ECG combined with mobile Internet can enhance the diagnostic efficiency and improve patients’ perceived control attitude and self-efficacy.

Abstract Introduction/Objective Chronic kidney disease (CKD) is affecting about 14% of the general population. CKD is associated with a decrease in calcium level in the body. In the early stages of (CKD), dialysis may not be needed. The late stages of CKD will require dialysis or a kidney transplant to save a life. Secondary hyperparathyroidism is a crucial disorder in CKD patients. It explains why the illness causes a significant change in bone and mineral metabolism. This study aims to study renal hyperparathyroidism (rHPT) in dialysis patients with late-stage of chronic kidney disease (CKD). Methods/Case Report A total of 55 subjects were enrolled in this study for late-stage dialysis patients from Egypt. Serum creatinine and PTH levels were measured. Among the 55 subjects; 41 subjects (74.5%) were males, 14 subjects (25.5%) were females with a mean age of 52.7 and 34.3 years for males and females, respectively. Subjects were divided into two groups; Study group I consists of 33 dialysis patients; three patients were females (9%) while 30 patients were males (91%), and control group II consists of 22 healthy individuals, 11 subjects were females (50%), and 11 subjects were males (50%). Results (if a Case Study enter NA) In our study, in comparison between two groups as regards blood investigations. The means of creatinine and PTH in the study group I were 8.93 mg/dl and 316.8, while in the control group II were 0.9, and 38.4 respectively. Comparing the two groups shows that mean of Creatinine and PTH in the study group was statistically significantly higher than the control group (p-value less than 0.001). Conclusion In patients with CKD, accurate measurement of (PTH) is critical for treatment decision-making to reduce the risk of bone and cardiovascular diseases. We recommend that patients with diabetes and high blood pressure be aware that they must take their medications consistently to avoid kidney problems.

The high prevalence of the vitamin D (VD) deficiency states (VDDS) among adults, as well as the data on the pleiotropic effects of calcitriol suggests its participation in the development of various complications and pregnancy outcomes. The objective of the present study is to analyze the pregnancy course and delivery tactics of pregnant women with placental dysfunction (PD) depending on the calcitriol availability. We examined 56 patients with PD (I – main group) and 40 conditionally healthy women with physiological pregnancy (II – control group). In addition to the standard clinical and laboratory examination, the level of vitamin D in the blood was determined by ELISA. The statistical analysis used the software Biostat, Statistica 6.0. In 76.8 % of group I women, the VD content corresponded to the deficit (38.4 %) and to the suboptimal status (38.4 %), (RR = 3.0; 95 % CI 2.39–3.76). In group II, VDDS was not detected and the suboptimal status was diagnosed in 31.45 %. The average VD level in group I was significantly lower than that in group II (31.4 ± 8.6 ng/ml vs 43.54 ± 11.2 ng/ml; Uemp = 42.5; p < 0.05). The caesarean section rate in group I was 3.4 times higher than that in group II (42.85 % vs 12.5 %; F = 0.00001; p < 0.01). The weight of newborns in group II significantly exceeded the weight of children in group I (3643.24 ± 136 g vs 3299.11 ± 128 g; t = 4.17; p < 0.01); a strong direct correlation was found between the weight of the newborn and the VD level in the blood of pregnant women (r = 0.71). VDDS increases 2 times the risk of abdominal delivery (RR = 1.27; 95 % CI 0.95–1.66). The VD status of a pregnant woman can have a certain influence on the formation of optimal adaptive-compensatory mechanisms in the utero-placental-fetal system and on the pregnancy outcome for mother and fetus.

Abstract Objective: To identify the differences of hemodynamic profile and morphometric changes of maternal heart in normotensive and severe preeclampsia (early-onset and late-onset) pregnant women. Method: Cross-sectional study on consecutively selected 34 pregnant women which divided into three groups: normotensive group (n = 12), early-onset group (n = 11), and the late-onset group (n = 11). Conducted in the ER and inpatient care unit of Obstetrics and Gynecology Department, Faculty of Medicine Sriwijaya University / Dr. Moh. Hoesin Hospital Palembang, from April 2015 - June 2015. Results: There are significant differences in CO and SVR among three groups. In early onset groups, CO values ​​are lower (3.4 + 0:27, p <0.001) with higher SVR (3100.2 + 261.3, p <0.001) compared the other two groups. There is increased of SVR in preeclamptic group compared to control, where SVR is higher in the early onset compared to late-onset group (3100.2 + 261.3 vs 2217.1 + 407.8, p <0.001), as well as differences between groups in cardiac index variables, except in the early onset group and controls (p = 0.045). In blood pressure and MAP variable, we only notice difference between the early onset group and control (p <0.001) as well as late-onset group and controls (p <0.001). There are significant differences in LVMi, LVID and LVPWT among three groups, in which the control group was lower than the other two groups (p <0.001; p = 0.049; p = 0.009), but similar in early and late-onset groups (98.7 (86.5-203) vs 132 (77.7-17.6); 4.7 (0.4) vs 4.8 (0.5); 1.1 (0.7-1.3) vs. 1.1 (0.8-1.6)). While RWT relatively similar among the three study groups (p = 0.264). A post hoc analysis showed no differences in maternal heart morphometry in early onset and late-onset group (p> 0.05). Conclusions: In severe preeclampsia there are changes in hemodynamic, ventricular morphometry, and left ventricular function. But the changes that occurred seems to be more evident in the early onset preeclampsia group of  compared than late-onset preeclampsia. Keywords: Normotensive, early onset PEB, PEB late-onset, hemodynamic profile, cardiac morphometry.

Background: A major challenge in obstetrics is early identification of hypertensive disorders of pregnancy (HDP). This study was performed to determine the association between elevated maternal serum β-hCG levels and HDP, the correlation between serum β-hCG level and severity of preeclampsia and to determine the value of serum β-hCG level as a diagnostic marker for early diagnosis of HDP.Methods: This was a hospital based observational study conducted in the department of obstetrics and gynecology, Rajendra Institute of Medical Sciences, Ranchi on 375 pregnant women with period of gestation more than 20 weeks, including 250 pregnant women with HDP as study group and 125 normotensive pregnant women as controls. Serum β-hCG concentration was measured and its level was compared between two groups.Results: The maternal mean serum β-hCG levels (51161.08±30038.21 IU/L) of study group of HDP were higher than the normotensive control group (17603.23±16748.21 IU/L). In non-severe preeclampsia, the mean serum levels were 36417.32±23876.74 IU/L while in severe preeclampsia, 60030.34±28771.31 IU/L. There was statistically significant difference (p<0.001) with higher levels in early onset preeclamptic mothers than late onset preeclampsia. The cut-off point of β-hCG for predicting HDP was 32077 IU/L with sensitivity of 65% and specificity of 86%.Conclusions: Serum β-hCG level is higher in HDP when compared to normotensive women. Higher levels of β-hCG are associated with increasing severity of hypertensive disorders of pregnancy. The utility of serum β-hCG as a diagnostic test is limited because of low sensitivity and difficulty in deciding the cut-off value.

Background: Various methods exist for treating post-operative pain which includes systemic narcotics, NSAIDS, patient-controlled analgesia, regional anaesthesia techniques, epidural local anaesthetic – narcotic mixtures, cryoanalgesia, transcutaneous electric nerve stimulation, psychological methods. Various opioides intrathecally and epidurally have been tried for post-operative analgesia. These include - morphine, pethidine, pentazocine, methadone, tramadol, Fentanyl, sufentanyl. In present study, we tried to find out analgesic effectiveness of intrathecal Fentanyl for post-operative analgesia, combined with 0.5 % Bupivacaine and side effects if any, in patients undergoing lower limb surgeries. Materials and Methods: After approval from the local ethics committee and with written informed consent from patient, a randomized controlled prospective study is carried out in the medical college and hospital.100 patients belonging to American Society of Anesthesiologists (ASA)classification I &amp; II, aged between 18-60 years, posted for elective lower limb surgeries, were randomly allocated for the study. Group-I: 50 patients received intrathecal 3 ml of 0.5 % hyperbaric Bupivacaine only. Group-II : 50 patients received intrathecal 3 ml of 0.5% hyperbaric Bupivacaine and Fentanyl 25 mcg.The patients studied across the group did not vary much with respect to age,height, weight and sex distribution. Results: The onset of sensory blockade was faster by 1.27 min in Group-BF. The perioperative and postoperative hemodynamic parameters were comparable in both the groups. The sensory analgesia in Group II was significantly prolonged by 159 mins, thus increasing the duration of analgesia. The time of first request of analgesics by the patients in group-II is prolonged compared to group-I thus prolonging the duration of analgesia. Analgesic requirement is also reduced in study group in early post-operative period. The onset of motor block was faster when Fentanyl was added to intrathecal Bupivacaine and it was 1.1 min earlier in study group. The duration of motor block to Bromage III was prolonged by almost 22 min in study group as compare to control group. Visual analogue scores were significantly lower in group-II compared to group-I after two hours of surgery thus reducing the frequency of supplemental postoperative analgesics. Conclusion: With the present study we can summarize that intrathecal Fentanyl potentiates the action of Bupivacaine thereby bringing about better quality and longer duration of analgesia, intense motor block, no hemodynamic disturbance and better postoperative outcome with/ minimum side effects.

The aim: Study of the relationship between cervical insufficiency and dysplastic stigma in miscarriages. Materials and methods: 80 pregnant women were examined at 23-27 weeks of gestation.) Group I included 40 pregnant women with the threat of premature birth, with habitual miscarriage and correction of cervical insufficiency (CI) by using pessary in the anamnesis. Group II consisted of 20 pregnant women with the threat of premature birth and correction of CI by using pessary without the burden of habitual miscarriage, the control group of 20 almost healthy pregnant women. Results: The studies revealed phenotypic signs of dysplastic stigmatization in 39 (97.5 + 2.5%) pregnant women of group I, in 18 (90.0 + 6.9%) group II and in 4 (20.0 + 9.2%) control, which indicates a high prevalence of connective tissue dysplasia in women with CI, which also has a laboratory reflection in the form of increased excretion per day of oxyproline and a decrease in total glycosaminoglycans in both groups at risk of preterm birth. Conclusions: The most common gestational complication in women with connective tissue dysplasia is the risk of premature birth. Improving existing and finding new diagnostic and therapeutic measures for women with UDСTD will reduce the risk of preterm birth.
