Early therapeutic plasma exchange may improve treatment outcomes in severe acute toxic Hepatitis

Transfus Apher Sci. 2021 Oct;60(5):103250. doi: 10.1016/j.transci.2021.103250. Epub 2021 Aug 17.

ABSTRACT

BACKGROUND AND OBJECTIVES: Acute toxic hepatitis can result in a different clinical course from a completely curable disease to subacute hepatitis, chronic hepatitis, and fulminant hepatitis failure, which is quite mortal. For this purpose, therapeutic plasma exchange (TPE) can be used for improving treatment outcomes by reducing the harmful substances caused with and/or without liver function in acute toxic hepatitis. We aimed to evaluate treatment outcomes in severe acute toxic hepatitis patients who applied early TPE procedure.

MATERIALS AND METHODS: A total of 335 patients who received TPE between 2010-2021 were retrospectively screened and 59 (male/female, 30/29; min/max-age, 22-84) patients with acute toxic hepatitis who underwent TPE in the first 24 h were included in the study. TPE was performed in patients who had high total bilirubin level (>10 mg/dL). Laboratory parameters of the patients before and after the TPE procedure, number of patients developed complications of acute toxic hepatitis and mortality rates were evaluated for effectiveness of TPE.

RESULTS: Acute toxic hepatitis was associated with hepatotoxic drugs in 44 (74.5 %), herbal medication 6 (10.2 %), mushroom poisoning 6 (10.2 %) and with substance abuse 3 (5.1 %) in patients. When the patients were compared based on INR, liver function tests, ammonia, lactate and Model For End-Stage Liver Disease (MELD) score at baseline, 48 h after TPE (independently of TPE number) and before final state a statistically significant decrease was observed in all parameters (p < 0.05). Fifty three (90 %) of patients improved without complications, the remaining 6 (10 %) patients were diagnosed with fulminant hepatitis. All these remaining patients died before liver transplantation (LTx) could be performed.

CONCLUSION: TPE is a safe, tolerable therapy option and early TPE may improve treatment outcomes in severe acute toxic hepatitis.

Influence of apnea vs hypopnea predominance in predicting mean therapeutic positive airway pressures among patients with obstructive sleep apnea

J Clin Sleep Med. 2021 Nov 1;17(11):2171-2178. doi: 10.5664/jcsm.9342.

ABSTRACT

STUDY OBJECTIVES: Lower therapeutic positive airway pressure (PAP) levels are associated with improved response to non-PAP therapies in the treatment of obstructive sleep apnea. The aim of this study was to evaluate the prevailing notion that patients with apnea-predominant obstructive sleep apnea require higher therapeutic PAP levels compared to patients with hypopnea-predominant obstructive sleep apnea.

METHODS: An institutional review board-approved retrospective review was performed using strict inclusion criteria: presence of type I or III sleep study, apnea-hypopnea index > 10 events/h, and adherence to auto-adjusting continuous positive airway pressure. Patients were stratified by apnea (> 50% apneas) or hypopnea (≤ 50% apneas) predominance, and PAP data were compared. Statistical analyses were performed using Student’s t test and linear regression modeling.

RESULTS: Between January 1, 2018 and January 1, 2020, 500 patients met inclusion criteria. Two hundred twenty-one (44.1%) patients were apnea-predominant and 279 (55.8%) were hypopnea-predominant. Apnea-predominant patients had a slightly greater mean PAP (9.01 vs 8.36, P = .002) than hypopnea-predominant patients. Univariable and multivariable linear regression of 7 variables (obstructive apnea percentage, age, sex, body mass index, apnea-hypopnea index, O2 nadir, mask type) showed obstructive apnea percentage was the weakest predictor of therapeutic PAP levels.

CONCLUSIONS: Apnea-predominant individuals demonstrated a clinically insignificant difference in PAP level compared to hypopnea-predominant individuals; moreover, obstructive apnea percentage was not a strong predictor of therapeutic PAP levels. Of the modeled variables, the strongest predictor of PAP level was apnea-hypopnea index. Further studies are needed to explore these relationships as well as additional variables that may contribute to predicting therapeutic PAP levels.

Adiponectin Ameliorated Pancreatic Islet Injury Induced by Chronic Intermittent Hypoxia through Inhibiting the Imbalance in Mitochondrial Fusion and Division

Chin Med Sci J. 2021 Sep 30;36(3):225-233. doi: 10.24920/003834.

ABSTRACT

Objective This study aimed to assess the protective value of adiponectin (APN) in pancreatic islet injury induced by chronic intermittent hypoxia (CIH). Methods Sixty rats were randomly divided into three groups: normal control (NC) group, CIH group, and CIH with APN supplement (CIH+APN) group. After 5 weeks of CIH exposure, we conducted oral glucose tolerance tests (OGTT) and insulin released test (IRT), examined and compared the adenosine triphosphate (ATP) levels, mitochondrial membrane potential (MMP) levels, reactive oxygen species (ROS) levels, enzymes gene expression levels of Ant1, Cs, Hmox1, and Cox4i1 which represented mitochondrial tricarboxylic acid cycle function, the protein and gene expression levels of DRP1, FIS1, MFN1, and OPA1 which represented mitochondrial fusion and division, and the protein expression levels of BAX, BCL-2, cleaved Caspase-3, and cleaved PARP which represented mitochondrial associated apoptosis pathway of pancreatic islet. Results OGTT and IRT showed blood glucose and insulin levels had no differences among the NC, CIH and CIH+APN groups (both P>0.05) at 0 min, 20 min, 30 min, 60 min, 120 min. However, we found that compared to NC group, CIH increased the ROS level, reduced ATP level and MMP level. The islets of CIH exposed rats showed reduced gene expression levels of Ant1, Cs, Hmox1, and Cox4i1, decreased protein and gene expression levels of MFN1 and OPA1, increased protein and gene expression levels of DRP1 and FIS1, increased protein expression levels of cleaved Caspase-3 and cleaved PARP, with lower ratio of BCL-2/BAX at protein expression level. All the differences among three groups were statistically significant. APN treated CIH rats showed mitigated changes in the above measurements associated with islet injuries. Conclusion APN may ameliorate the pancreatic islet injury induced by CIH via inhibiting the imbalance in mitochondrial fusion and division.

Dietary Supplementation with Casein Glycomacropeptide, Leucine and Tryptophan Reduces Plasma Amino Acid Levels in Men

Acta Neuropsychiatr. 2021 Oct 20:1-28. doi: 10.1017/neu.2021.34. Online ahead of print.

ABSTRACT

BACKGROUND: The treatment of mania in bipolar disorders needs to be more efficient, as the manic condition creates severe problems for the patient when it comes to work, finances, relationships, and health. This proof-of-concept study examines to what extent casein glycomacropeptide (CGMP) may reduce the precursors of dopamine, phenylalanine, and tyrosine, in plasma, and therefore be a potential new intervention to treat acute manic episodes.

METHOD: The study was designed as a double-blind randomised dose-response study of CGMP (with added leucine and tryptophan) in 15 healthy men, receiving 3 different doses of CGMP with an interval of at least 14 days.

RESULTS: Administration of CGMP produced a dose dependent depletion of plasma aromatic amino acids. The total area under the curve of plasma ratios of phenylalanine-tyrosine compared to the level of leucine-isoleucine-valine-tryptophan was CGMP(20g): 3.648 [SE:0.3281]; CGMP(40g): 2.368 [SE:0.1858]; CGMP(60g)1.887 [SE:0.2591]. A comparison of the groups showed a dose dependent statistical difference, with a One-Way ANOVA summary (Dunnett) F= 11.87, p= 0.0003, CGMP 20g vs CGMP 40g, p= 0.0042, CGMP 20g vs CGMP 60g, p= 0.0002. No significant side effects were observed.

CONCLUSIONS: This study demonstrate CGMP is a well-tolerated and effective mixture, and that 60 g CGMP produced the highest depletion of plasma aromatic amino acids (phenylalanine and tyrosine). The effect seems to be highest after 3-4 hours. We therefore conclude that this dose should be the one considered for future studies involving CGMP in humans.

The effects of psychological risk factors at work on cognitive failures through the accident proneness

BMC Psychol. 2021 Oct 19;9(1):162. doi: 10.1186/s40359-021-00669-5.

ABSTRACT

BACKGROUND: Various agents such as psychosocial items and accident proneness can affect cognitive failures through different paths. The probable paths are the direct effects of workplace psychosocial items on cognitive failures and their indirect effects on cognitive failures through the mediator variable of accident proneness, which has not yet been studied by others. Thus, the present study aimed to investigate these paths.

METHODS: This cross-sectional study was conducted on 164 male employees of Karoon Sugar Company in 2018. The participants were asked to complete a background and demographic questionnaire, Broadbent cognitive failures scale, accident proneness questionnaire, and Copenhagen psychosocial questionnaire. Obtained data were analyzed and modeled using the statistical descriptive method, ANOVA, independent t-test, Pearson correlation test, and path analysis in the SPSS and AMOS software.

RESULTS: The results of the path analysis showed that, not only, some psychosocial risk items had a significant direct effect on cognitive failures, but also, they could affect cognitive failures through the accident proneness, indirectly. Work-family conflict and social support from supervisors by coefficients of 0.188 and – 0.187 had the highest direct effects, respectively. The highest indirect effects belonged to justice and respect, and work-family conflict by coefficients of – 0.220 and 0.199, respectively. The highest total effects were also related to the work-family conflict and justice and respect by coefficients of 0.387 and – 0.381, respectively.

CONCLUSIONS: In total, our results showed that some psychological items could, directly and indirectly, increase cognitive failure through accident proneness.

Comparison of different symmetry indices for the quantification of dynamic joint angles

BMC Sports Sci Med Rehabil. 2021 Oct 19;13(1):130. doi: 10.1186/s13102-021-00355-4.

ABSTRACT

BACKGROUND: Symmetry is a sign of physiological and healthy movements, as pathologies are often described by increased asymmetries. Nevertheless, based on precisely measured data, even healthy individuals will show small asymmetries in their movements. However, so far there do not exist commonly accepted methods and reference values for gait symmetry in a healthy collective. Therefore, a comparison and presentation of reference values calculated by 3 different methods of symmetry indices for lower limb joint angles during walking, ascending, and descending stairs were shown.

METHODS: Thirty-five healthy participants were analyzed during walking, ascending, and descending stairs with the help of the inertial measurement system MyoMotion. Using the normalized symmetry index (SInorm), the symmetry index (SI) as the integral of the symmetry function, and another normalized symmetry index (NSI), the symmetry of joint angles was evaluated. For statistical evaluation of differences, repeated measurement models and Bland-Altman-Plots were used.

RESULTS: Apart from a bias between the symmetry indices, they were comparable in the predefined limits of 5%. For all parameters, significantly higher asymmetry was found for ankle dorsi/-plantarflexion, compared with the hip and knee flexion. Moreover, the interaction effect of the joint and movement factors was significant, with an increased asymmetry of the hip and knee during descending stairs greater than while ascending stairs or walking, but a reduced symmetry of the ankle during walking when compared to descending. The movement only showed significant effects when analyzing the SInorm.

CONCLUSION: Even for healthy individuals, small asymmetries of movements were found and presented as reference values using 3 different symmetry indices for dynamic lower limb joint angles during 3 different movements. For the quantification of symmetrical movements differences between the joints, movements, and especially their interaction, are necessary to be taken into account. Moreover, a bias between the methods should be noted. The potential for each presented symmetry index to identify pathological movements or track a rehabilitation process was shown but has to be proven in further research.

Assessment of patient satisfaction towards auditable pharmaceutical transactions and services implemented in outpatient hospital pharmacy in Ethiopia

J Pharm Policy Pract. 2021 Oct 19;14(1):83. doi: 10.1186/s40545-021-00372-1.

ABSTRACT

BACKGROUND: Patient satisfaction is a widely used indicator to measure quality of pharmacy services. Currently, a transformational pharmacy service called auditable pharmaceutical transactions and services is being implemented nationally in Ethiopia. However, there is a dearth of evidence regarding the national impact of this system on patient satisfaction.

OBJECTIVE: To assess patient satisfaction in hospital pharmacies that have implemented auditable pharmaceutical transactions and services in Ethiopia.

METHOD: This is a national study conducted based on a cross-sectional study design. Data were collected using a structured questionnaire from September 5 to October 5, 2020. The collected data was analyzed using spreadsheet excel and Statistical Package for the Social Sciences (SPSS) version 23. The proportions, ratios, and percentages were used for presenting data. A binary logistic regression test was used to determine the association of patient satisfaction with dispensary infrastructure, medicines availability, scores of labeling, and scores of patient knowledge on dispensed medicines. A p value < 0.05 was considered statistically significant.

RESULT: A total of 650 participants were included in this study for whom a total of 1422 medicines were prescribed which gives an average of 2.19 medicine per patient. The availability of the prescribed medicines in the pharmacies was 1061 (75%), and the affordability of medicines was 1.93 WD that indicates an unaffordable price. The average written medication labels score of 3.1 out of 8 points and the average patient knowledge score for correct usage of medicines was 4.5 out of 6 points. Overall, 585 (90%) of patients reported being satisfied with pharmacy services; the counseling skill of pharmacists 609 (93.7%), and dispensing area 607 (93.4%) cited the most. The only significantly associated factor for satisfaction was the infrastructure of the pharmacy.

CONCLUSION: Overall satisfaction of patients with the auditable pharmaceutical transactions and services implemented in hospital pharmacy services was generally high. The participants were most satisfied with the pharmacist counseling and dispensary area. The medication availability is moderate but the cost is unaffordable. Advanced infrastructures have resulted in a significant improvement in patient satisfaction.

Effects of high flow nasal cannula on the coordination between swallowing and breathing in postextubation patients, a randomized crossover study

Crit Care. 2021 Oct 19;25(1):365. doi: 10.1186/s13054-021-03786-0.

ABSTRACT

BACKGROUND: Timing of swallows in relation to respiratory phases is associated with aspiration events. Oxygen therapy possibly affects the timing of swallows, which may alter airway protective mechanisms.

OBJECTIVES: To compare the coordination between swallowing and respiration during water infusion in post-extubation patients using high flow nasal oxygen (HFNO) with the coordination in those using low flow nasal oxygen (LFNO).

METHODS: We conducted a randomized controlled crossover study in post-extubation patients. The patients extubated within 48 h were randomly assigned to two groups, namely, HFNO and LFNO. The eligible patients in each group received either HFNO with fraction of inspired oxygen (FiO2) 0.35, flow 50 L per minute (LPM), and temperature 34 °C or LFNO 5 LPM for 5 min. The coordination between swallowing and respiration was observed during continuous infusion of 10-ml water one minute three times. Respiratory phases and swallowing were monitored using electrocardiogram (EKG)-derived respiratory signals and submental electromyography (EMG), respectively. The swallowing frequency and timing of swallows in relation to respiratory phases were recorded. The coordination between swallowing and respiration was classified into 4 patterns, namely I, E, I-E, and E-I swallows. (I; inspiration and E; expiration) Subsequently, after a 5-min washout period, the patients were switched to the other type of oxygen therapy using the same procedure. The Wilcoxon Signed-Rank Test was used for statistical analysis.

RESULTS: A total of 22 patients with a mean age of 56 years were enrolled in the study. The major indication for invasive mechanical ventilation was pneumonia with a median duration of endotracheal intubation of 2.5 days. The median total swallowing numbers (three minutes) were 18.5 times in the HFNO period and 21 times in the LFNO period (p = NS). The most common swallowing pattern was E-swallow. The patients using HFNO had higher numbers of E-swallow pattern (74.3% in HFNO vs 67.6% in LFNO; p = 0.048) and lower numbers of I-swallow pattern (14.3% in HFNO vs 23.1% in LFNO; p = 0.044). The numbers of other swallowing patterns were not different between the 2 groups.

CONCLUSIONS: Compared with LFNO, HFNO significantly increased the E-swallow and decreased the I-swallow in post-extubation patients. The findings indicated that HFNO might reduce a risk of aspiration during the post-extubation period. Clinical trial No.: Thai clinical trial TCTR20200206004 Registered February 4, 2020.

Undetectable thyroglobulin makes 123I whole-body scan and stimulated thyroglobulin obsolete in follow-up care of differentiated thyroid cancer: a retrospective study

Thyroid Res. 2021 Oct 19;14(1):23. doi: 10.1186/s13044-021-00114-0.

ABSTRACT

BACKGROUND: Differentiated thyroid cancer (DTC) is a common malignancy with increasing incidence. Follow-up care for DTC includes thyroglobulin (Tg) measurement and ultrasound (US) of the neck, combined with 131I remnant ablation when indicated. Diagnostic precision has evolved with the introduction of the new high-sensitive Tg-assays (sensitivity ≤0.1 ng/mL). The aim of the study was to determine the prognostic utility of high-sensitive Tg and the need for other diagnostic tests in DTC.

METHODS: This was a retrospective, observational study. Patients with pathologically confirmed DTC, treated with total thyroidectomy and 131I remnant ablation, who had their complete follow-up care in our institution were selected (October 2013-December 2018). Subjects with possible thyroglobulin autoantibody interference were excluded. Statistical analysis was performed using the IBM SPSS® Statistics 24 software package.

RESULTS: Forty patients were eligible for analysis. A total of 24 out of the 40 patients (60%) had an undetectable high-sensitive Tg 6 months after total thyroidectomy. None of these patients had a stimulated Tg above 1 ng/mL, or remnant on the 123I Whole-Body Scan (WBS) after 1 year of follow-up. Ultrasound of the neck, performed between 6 and 12 months postoperative, was negative in 21 out of the 24 patients.

CONCLUSIONS: This study shows that an undetectable high-sensitive Tg can change the management of patients with DTC and decrease the use and need of stimulated Tg and 123I WBS.

Effect of single-incision laparoscopic distal gastrectomy guided by ERAS and the influence on immune function

World J Surg Oncol. 2021 Oct 20;19(1):307. doi: 10.1186/s12957-021-02422-z.

ABSTRACT

BACKGROUND: To evaluate the immune function of gastric cancer patients after single-incision laparoscopic distal gastrectomy (SIDG) or multiport laparoscopic distal gastrectomy (MLDG) guided by enhanced recovery after surgery (ERAS).

METHODS: A retrospective cohort study was performed on 120 patients who underwent laparoscopic distal gastrectomy for gastric cancer. The patients were divided into two groups according to operation method: group A (MLDG) and group B (SIDG), both guided by ERAS concept. The indicators reflecting immune function and inflammation, such as CD3+, CD4+, CD8+ and NK cell count, CD4+/CD8+ cell ratios, IgA, IgM and IgG levels, C-reactive protein (CRP), total lymphocyte count (TLC) and neutrophil-to-lymphocyte ratio (NLR) were tested 3 days and 7 days after surgery.

RESULTS: The skin incision length of patients in group B was significantly shorter than that in group A, but the operation time was significantly longer in group B than that in group A (P < 0.05). There were no significant differences in preoperative CD3+, CD4+, CD8+, natural killer (NK) cells, CD4+/CD8+, IgA, IgM and IgG levels between two groups (P < 0.05). Three days after surgery, the immune function indices were decreased in both groups, but with no significant difference between two groups (P > 0.05). On the 7th day after surgery, the immune indexes of both groups recovered somewhat, approaching the preoperative level (P > 0.05). Inflammation indexes increased 3 days after surgery and decreased 7 days after surgery in both groups, among them the CRP level in group A was higher than that in group B (P < 0.05). The 3-year survival rate were 96.7% in group A and 91.7% in group B, respectively, with no statistically significant difference.

CONCLUSION: Compared with MLDG guided by ERAS, SIDG under the guidance of the ERAS concept has better cosmetic effect and similar effect on immune function of gastric cancer patients.
