The pregnant diabetic at or near term, in the absence of clinical metabolic disorder, ordinarily exhibits only minor differences from normal pregnant women in regard to pH, content of gases, and concentration of hemoglobin in blood and concentration of electrolytes in plasma. The diabetic in labor is likely to evidence signs of metabolic acidosis which is only partially compensated. The fetus of the diabetic, on the other hand, is frequently found to have marked changes in pH, pCO2 and oxygen saturation of the blood. There is a small decrease in total concentration of electrolytes, which is apparently related to dilution of the blood. Concentration of hemoglobin is slightly increased, but if dilution is taken into consideration, this probably represents a significant increase in total hemoglobin mass. The variability of several components of the blood is greater than in normal fetuses. The changes in pH and pCO2 are sufficient, in their effect on dissociation of oxyhemoglobin, to account for the mean decrease in saturation observed in the fetuses of diabetics without any change in pO2. The average fetus, therefore, cannot properly be said to be hypoxic. However, individual fetuses are observed with very marked reductions in oxygen saturation which undoubtedly reflect true hypoxia. Biochemical alterations in these fetuses are out of proportion to maternal changes but, once proper pulmonary ventilation is established, can be readily reversed. It appears from this that the lesion is likely to be placental rather than maternal or fetal. Biochemical deviations from normal in the present series are only irregularly related to neonatal difficulty. The two infants who died in the present study were the only prematures, and only one manifested severe and disproportional changes. The biochemical changes observed do not per se appear to be sufficient to account for the known neonatal difficulties of the infants of diabetic mothers, but, in aggravated form, might account for fetal death.

The arterial oxygen saturation was determined in 135 healthy newborn infants during sleep and while crying with a direct reading single scale oximeter. In the first group, consisting of infants from one hour and 30 minutes to 3 days of age, 66% showed a decrease of oxygen saturation with crying, 27% an increase and 6.8% no change. In the second group, which includes all infants between 4 and 9 days of age, 59% showed an increase in saturation with crying, 21% a decrease and 22.4% no change. In comparison, the mean results in these two groups are in the opposite direction. These changes are statistically significant. Twenty-eight infants were studied also while breathing oxygen (73%-98.5%), and the results compared with those in room air were found to show an identical trend. It is concluded that increases in arterial oxygen saturation with crying, which occur most frequently in older infants, are probably due to an increase in alveolar oxygen tension secondary to improved pulmonary ventilation during crying. The paradoxic decrease in saturation during crying, which was found in a large percentage of infants of the younger group, is suggestive of the presence of a transitory venous-arterial shunt. This shunt could be either through atelectatic areas of the lung or through the foramen ovale, which is only functionally closed and can open whenever the pressure in the right auricle exceeds the left auricular pressure. There is some available evidence to support the latter possibility.

Simultaneous plasma free fatty acid (FFA) and blood sugar levels were determined for fasting newborn infants during the first 24 hours of life, for their cord bloods, and for their mothers at delivery. The following observations were made. In control infants the mean FFA level rose about three times the cord level after birth and was accompanied by a 25% drop in the mean blood sugar level. Thereafter, the mean blood sugar level remained relatively constant, but the mean FFA level varied from 2½ to 3 times the cord level. There was no significant correlation between the length of maternal fasting prior to delivery and the infant FFA level; there was, however a significant negative correlation between the length of maternal fasting prior to delivery and the infant blood sugar level at 24 hours of age. High FFA levels occurred in the infants of obese mothers and low levels were observed in infants with delayed respirations, in infants of preeclamptic mothers, and in infants of diabetic mothers.

The aim: To perform a comprehensive evaluation of the effect of paroxetine on the degree of somatoform disorders in exacerbation of severe COPD in women. Materials and methods: The study involved 53 female patients with severe COPD (Group D), confirmed by instrumental methods of study. At hospitalization, patients were divided into 2 groups. Patients of Group 1 (n = 21; aged 52.5 ± 0.8 years old) underwent basic exacerbation therapy. Patients of Group 2 (n = 22; aged 57.9 ± 0.4 years old) underwent basic exacerbation therapy supplemented with paroxetine for 14 days, 1 tablet (0.20 g) once a day. Results: The basic therapy for treatment of COPD exacerbations, supplemented with paroxetine, led to a positive clinical effect, confirmed by increase in skeletal and respiratory muscular system, increased parameters of pulmonary ventilation, increased tolerance to physical load, increased oxygen saturation, decreased heart rate and breathing rate. Conclusions: The strategy for choosing an antidepressant to provide multidisciplinary care for somatoform disorders in women with exacerbation of severe COPD (group D) should take into account the efficacy and favorable safety profile and personalization of the drug. In exacerbation of severe COPD, the degree of somatoform disorders in patients correlates with the severity of the main criteria: FVC1, the distance walked during the 6-minute step test, oxygen saturation after the 6-minute step test, end-expiratory pressure in the oral cavity.

We present the use of Extended Modified Lambert–Beer model for optical monitoring of mean blood oxygen saturation ( S m O 2) via a fitting procedure. This work focuses on the absorption characteristics of hemoglobin derivatives in the wavelength range of 520–600 nm to give the best estimates of S m O 2. The study of the feasibility of applying this analytic method to skin oximetry is via spectroscopy data collected from fingertips of four healthy volunteers both at rest and during arterial blood occlusion condition. The results revealed a decrease in the mean of mean and standard deviation of S m O 2 value of fingertips from 94.5 ± 2.19% when volunteers were at rest to 56.76 ± 5.8% during the arterial blood occlusion measurement. The larger variation in the value estimated for blood occlusion condition could be a result of differences in volunteers' physical fitness and hypertension status. These estimated S m O 2 values agreed reasonably well with the value reported in most of the previous studies. This work concluded that the proposed technique can potentially be used as a complementary technique to clinical assessment of skin grafts and burnt skin.

Obstructive sleep apnea (OSA) and obesity are two interacting global epidemics both with high prevalence and morbidity. Both epidemiologic and clinical studies suggest that majority of patients with obesity also have OSA and untreated OSA in these patients results in significant cardiovascular and metabolic complications.Objectives: To evaluate the profile of OSAin obese patients of Kashmir.Methods: We performed polysomnography studies in obese patients that were referred from various sub-specialty clinics from July 2011 to August 2013.Results: Out of 182 patients who underwent polysomnography (PSG), 11O (60.4%) were obese (BMI > 30 kg/m2). In 110 obese patients, 104 (94.5%) had OSA. Hypertension, diabetes and dyslipidemia were more prevalent among obese (p<0.05). The mean neck circumference and mean BMI of obese patients was significantly more than that of non-obese (33.9 kg/m2 vs. 26.8 kg/m2) (p <0.000). Presenting symptoms of obese were snoring (97.3%), daytime sleepiness (87.3%) with a mean ESS of 15.3, disturbed nocturnal sleep (70.0%), nocturia (62.7%) and witnessed apneas (45.5%). OSA was significantly (p=0.002) more common among obese compared to non-obese (93% vs 76%). Most were clinically suspected to have OSAby internists (29%), cardiologists (20%), endocrinologists (15%) and psychiatrists (13%). Sleep efficiency was significantly less (p< 0.03) in obese patients but sleep latency and REM sleep latency did not significantly differ between obese and non-obese. Unlike awake oxygen saturation the average nocturnal oxygen saturation of obese patients was significantly less [p=0.001] than that of nonobese patients (84.7% vs. 88.1%). The mean AHI of obese patients was significantly more than non-obese i.e 24.3 vs. 18.0 (p = 0.001) and so was the mean ODI i.e 24.6 vs. 17.2 (p = 0.001). Variables that significantly correlated with presence of OSA include age, gender, BMI, hypertension, diabetes and cardiovascular disease (p< 0.05), however on logistic regression only BMI, hypertension, and nocturia correlated with OSA. CPAPtherapy improved snoring, nocturia, nocturnal sleep and daytime sleepiness more in obese than non-obese OSApatients.Conclusions: OSA which is highly prevalent among obese Kashmiri patients, is largely unrecognized in the primary care setting. It is associated with significant comorbidities and most of these improve with CPAPtherapy. JMS 2016; 19(2):65-74.

Background: Endotracheal suctioning is one of the common supportive measures in intensive care units (ICU), which may be related to complications such as hypoxia. However, a questionable efficacy is still identified to choose suctioning pressure between 130 mmHg and 140 mmHg that is effective for patients with endotracheal tube.Objective: To compare the effectiveness of 130 mmHg and 140 mmHg suctioning pressure on oxygen saturation in patients with endotracheal tube.Methods: This research used a quasy experimental design with pretest and posttest group. The study was conducted from 31 January to 1 March 2017 in the Hospital of Panti Wilasa Citarum and Hospital of Roemani Muhammadiyah Semarang. There were 30 samples recruited using consecutive sampling, with 15 assigned in the 130 mmHg and 140 mmHg suctioning pressure group. Pulse oximetry was used to measure oxygen saturation. Paired t-test and Independent t-test were used for data analysis.Results: Findings showed that there was a statistically significant effect of 130 and 140 mmHg suctioning pressure on oxygen saturation in patients with ETT with p-value <0.05. There was a significant mean difference of oxygen saturation between 130 mmHg and 140 mmHg suctioning pressure group with p-value 0.004 (<0.05). The mean difference of oxygen saturation between both groups was 13.157.Conclusion: The 140 mmHg suctioning pressure is more effective compared with 130 mmHg suctioning pressure in increasing oxygen saturation in patients with ETT.

Background: Leptadenia hastata (L. Hastata) is a plant used for various diseases in Nigeria. This study evaluated the protective effects of L. hastate on the haematological and biochemical alterations in adrenaline-induced hypertensive rats. Methods: Twenty-five rats were divided equally into five groups (A-E). Groups A-D were given 0.5 mg/kg adrenaline, groups A and B were treated with 100 and 200 mg/kg the extract of L. Hastata, respectively, while groups C and D were treated with 5 mg/kg amlodipine (standard control) and normal saline (untreated control), respectively. Group E were given distilled water (normal controls). The adrenaline was injected intraperitoneally while the extract was given orally once daily for seven days. Results: Treatment with 100 and 200 mg/kg of the extract significantly reduced the elevated serum albumin, ALP, ALT, AST, chloride, sodium and creatinine, cholesterol and LDL concentrations compared with the untreated hypertensive rats. The bicarbonate level, WBC and RBC counts, mean cell hemoglobin and packed cell value were higher in rats treated with the extract compared with the untreated hypertensive rats. The mean cell value, HDL, triglyceride, urea, potassium, total and direct bilirubin concentrations in experimental groups were not significantly different from those in the controls (P<0.05). Conclusion: Our results suggest that treatment of the hypertensive rats with the extract of L. Hastata protects against renal, hepatic and cardiac damages, thus it could be considered as a natural anti-hypertensive agent. Further studies are required to identify the bioactive constituents and the mechanism(s) of action.

Abstract Background Since outbreak of COVID-19 pandemic clinical data from various parts of the world have been reported, until now there has been no provide data from Bosnia and Herzegovina (B&H) about COVID-19. Aim was to report on the first cohort of patients from B&H and to analyze clinical factors of COVID-19 patients that influence the length of hospitalization. Methods Retrospective cohort study conducted at UKC Tuzla. The study included 25 COVID-19 positive patients that were hospitalized between March 28th and April 27th 2020. The LOH was measured from the time of admission to discharge. Hospitalization greater than 10 days was considered as prolonged. Factors analyzed induced age, BMI, comorbidities, serum creatinine and oxygen saturation upon admission.Results The mean age was 52.92±19.15 years and BMI 28.80±4.22. LOH for patients with normal BMI was 9±SE2.646 days (CI 95% 3.814-14.816) vs 14.182 ±SE .937 (CI 95% 12.346-16.018; p<0.05) for ≥25 BMI. Patients without underlying diseases had a LOH of 11.70 ±SE1.075 (CI 95% 9.592-13.808), while those with comorbidities 14.8 ±SE1.303 (CI95% 12.247-17.353; p<0.05). Conclusion LOH varied among COVID-19 patients and was prolonged when clinical characteristics such as elevated BMI, comorbidities, elevated creatinine and low oxygen saturation levels were taken into consideration. Furthermore, risk factors for COVID-19 patients in B&H do not deviate from data reported in other countries.

Abstract. In a study with 12 calves on milk nutrition, the course of methemoglobinemia as well as ttansrenal passage of nitrates and nitrites after single per os administrations of 4 g NaNO2 per animal and 30 g KNO3 per animal in the form of water Solutions has been observed. The response of the organism of calves to per os administered doses of sodium nitrite and potassium nitrate was observed by the determination of tlie methemoglobin percentage in blood and the nitrate and nitrite content in urine before the administration ofthe respective dose and after h 1, 2, 3 and 4 after the administration. A significant elevation in the values of methemoglobin was recorded after h 2 after the administration of 4g NaNO3 per animal. The mean value of methemoglobin in blood was 18.84% of total hemoglobin. A slight decline in the values occurred as early as after h 3 after the administration. Of clinical signs, cyanosis of visible mucosae was observed. The highest nitrite and nitrate values in urine were determined after h 2 after per os administration of 4g NaNO2, With the administration of 30g KNO3 per animal, the most pronounced elevation in methemoglobinemia was observed after h 3, when the means values of methemoglobin was 11,75%. Of clinical signs, only slight cyanosis of mucosae was detectable. Maximum values of nitrates in urine of experimental calves after h 3 after the administration of 30 g KNO3 per animal, with the mean value of 29,9 mM NO3−1 clearly demonstrate a good transrenal passage of nitrates in calves on milk nutrition.
