Published: May 2021

Background: The six-month exclusive breastfeeding (EBF) rate almost halved between 2009 and 2013 in Northeast Thailand for no clear reason. Specific facilitators and barriers to six-month EBF have been identified for Thailand, but mothers’ views on these factors to continuing EBF breastfeeding until six months have not been explored in this region. Aim: This study aimed to prioritize mothers’ views on the identified facilitators and barriers of continuing six-month exclusive breastfeeding. Methods: Q-methodology was applied. This research was conducted at Well Baby Out-Patient Department of Khonkaen Hospital, Numphong Hospital and a private hospital. Thirty-four mothers, who had recently delivered infants aged between four and six months, were breastfeeding/had breastfed, were 20 to 40 years old, participated. Demographic data were analysed descriptively, and Q-method analysis was conducted using the PQ Method software 2.35. Results: There was consensus that having knowledge about the advantages of EBF was the most important facilitator of six-month EBF, and ‘not having any other responsibilities besides caring for her infant’ was the least important facilitator of six-month EBF. Three viewpoints emerged identifying different groups/clusters of mothers, namely, (1) caring for self, (2) requiring support and (3) breastfeeding knowledge. Conclusions: Despite some consensus among participants, three distinct viewpoints emerged regarding which facilitators and barriers were important to mothers. It is clear that a programme to improve the six-month EBF rate in Northeast Thailand would need to incorporate interventions or activities that address the different viewpoints identified.

Published: May 2021

Background: Psoriasis is a chronic, immune-mediated skin disease. It affects skin and joints, characterized by abnormal hyperproliferation of keratinocytes. The worldwide prevalence of psoriasis ranges from 2% to 4%. Environmental factors as smoking, alcohol consumption obesity can also work as triggers. During the inflammatory process, there is an exacerbated formation of free radicals and antioxidants are required to maintain redox balance. Aim: Assess antioxidant profiles. Methods: A cross-sectional study was conducted between August/2012 and March/2014. Sociodemographic, lifestyle, and biochemical measurements, dietary intake, serum lycopene and α-tocopherol, psoriasis severity according to Psoriasis Area and Severity Index were obtained. Comparisons between serum lycopene and α-tocopherol distributions according to variables were conducted using a one-way analysis of variance. Multiple linear regression was used to investigate factors associated with serum antioxidants. Results: 81 participants (56% female, 62% non-white), 34% without psoriatic lesions, 51% diagnosed with mild psoriasis, and 15% with moderate psoriasis. Median (IQR) age of 54 (41, 62) years, 10 (4, 11) years of education, 17% smokers, 46% overweight and 25% obesity. In total, 72% did not reach the daily recommendation of fruit and vegetable intake. Serum lycopene and α-tocopherol were 0.2 (0.1–0.3) µmol/L and 22.5 (18.5–25.6) µmol/L, respectively. Only 14% presented adequate concentration of lycopene, but adequate α-tocopherol level was observed among 88%. Conclusions: Patients reported a diet low in vegetables and fruits and rich in ultra-processed foods and fatty acids. Adequate circulating α-tocopherol but low serum lycopene, was observed among patients. A linear trend was observed for lycopene according to the severity of psoriasis.

Introduction: The contribution of fluid temperature to the effect of crystalloid fluid bolus therapy (FBT) in post-cardiac surgery patients is unknown. We evaluated the hemodynamic effects of FBT with fluid warmed to 40°C (warm FBT) versus room-temperature fluid. Methods: In this single centre prospective before-and-after study, we evaluated the effects of 500 ml of warm versus room-temperature compound sodium lactate administered over <30 minutes, in 50 cardiac surgery patients admitted to ICU. We recorded hemodynamics continuous before and for 30 minutes after the first FBT. We defined CI responsiveness (CI-R) as an CI increase >15% of baseline immediately after FBT and effect dissipation if the CI returned to <5% of baseline and MAP responsiveness as >10% increase and dissipation as return to <3 mmHg of baseline. Results: Hypotension (56%) and low CI (40%) typically triggered FBT. Temperature decreased >0.3°C in 13 (52%) patients after room-temperature FBT versus 0 (0%) after warm FBT (p < 0.01). CI and MAP responsiveness was similar (16 [64%] versus 11 [44%], p = 0.15 and 15 [60%] versus 17 [68%], p = 0.77, respectively). Among CI responders, CI increased more with room-temperature FBT (+0.6 [IQR, 0.5–1.1] versus +0.5 [IQR, 0.4–0.6] L/min/m2, p = 0.01). However, dissipation was more common after room-temperature versus warm FBT (9/16 [56%] versus 1/11 [9%], p = 0.02). Conclusion: In postoperative cardiac surgery patients, warm FBT preserved core temperature and induced smaller but more sustained CI increases among responders. Fluid temperature appears to impact both core temperature and the duration of CI response.

Published: May 2021

Aim: Recently, a new inflammatory and prognostic marker has emerged called as Systemic Immune Inflammation Index (SII). In the current study, we searched the relation between SII and Coronary Collateral Circulation (CCC) formation in stable Coronary Artery Disease (CAD). Materials & methods: 449 patients with stable CAD who underwent coronary angiography and documented coronary stenosis of 95% or more in at least one major coronary vessel were included in the study. The study patients were divided into two groups according to the Rentrop score as well CCC (Rentrop 2–3) and bad CCC (Rentrop 0–1). Blood samples for SII and other laboratory parameters were gathered from all the patients on admission. The SII score was formulized as platelet × neutrophil/lymphocyte counts. Results: Patients, who had developed bad CCC had a higher C-reactive protein (CRP), neutrophil/lymphocyte ratio (NLR), platelets/lymphocyte ratio (PLR) and SII levels compared to those who had developed well CCC (p < 0.001, for all). Multivariate logistic regression analysis showed that high levels of SII was an independent predictor of bad CCC (OR: 1.005, 95% confidence interval (CI): 1.003–1.006, p < 0.001) together with dyslipidemia, high levels of CRP and NLR. In Receiver Operator Characteristic curve (ROC) analysis, the optimal cutoff value of SII to predict poor CCC was found to be 729.8, with 78.4% sensitivity and 74.6% specificity (area under ROC curve = 0.833 (95% CI: 0.777–0.889, p < 0.001). Conclusion: We have demonstrated that SII, a novel cardiovascular risk marker, might be used as one of the independent predictors of CCC development.

Published: May 2021

Background: Delivery of community-based end-of-life care for patients and family members has been recognized as an important public health care approach. Despite differences in different healthcare settings and the significance of a person-centered approach, little research has investigated facilitators of community-based end-of-life care from the perspective of service recipients. In particular, there has been limited exploration of strategies to ensure positive outcomes at an operational level. Aim: To explore factors facilitating positive end-of-life care provision in community-based settings and how these are achieved in practice, from the perspectives of patients and family caregivers. Design: A qualitative cross-sectional descriptive study was undertaken through semi-structured interviews with patients and family caregivers subjected to thematic analysis. Setting/participants: Ten patients and 16 family caregivers were recruited from an end-of-life community care program provided by four non-governmental organizations in Hong Kong. Results: Seven core themes were identified: positive emotions about the relationship, positive appraisals of the relationship, care through inquiring about recipients’ circumstances, instrumentality of care (i.e. information, coaching on care, practical help, psychological support, multiple activities), comprehensiveness of care (i.e. diversity, post-death care, family-level wellbeing), structure of care (i.e. timely follow-up, well-developed system), and qualities of workers. Conclusions: Improvement in service quality might be achieved through alternating the perceptions or emotional reactions of care recipients toward care providers and increased use of sensitive inquiry. Comprehensive care and positive outcomes might be facilitated by addressing the dualities of care by providing diverse choices in pre-death and post-death care.

Published: May 2021

Background More stringent policies for addressing conflicts of interest have been implemented around the world in recent years. Considering the value of revisiting conflict of interest quality standards set by the International Patient Decision Aid Standards (IPDAS) Collaboration, we sought to review evidence relevant to 2 questions: 1) What are the effects of different strategies for managing conflicts of interest? and 2) What are patients’ perspectives on conflicts of interest? Methods We conducted a narrative review of English-language articles and abstracts from 2010 to 2019 that reported relevant quantitative or qualitative research. Results Of 1743 articles and 118 abstracts identified, 41 articles and 2 abstracts were included. Most evidence on the effects of conflict of interest management strategies pertained only to subsequent compliance with the management strategy. This evidence highlighted substantial noncompliance with prevailing requirements. Evidence on patient perspectives on conflicts of interest offered several insights, including the existence of diverse views on the acceptability of conflicts of interest, the salience of conflict of interest type and monetary value to patients, and the possibility that conflict of interest disclosure could have unintended effects. We identified no published research on the effects of IPDAS Collaboration conflict of interest quality standards on patient decision making or outcomes. Limitations Because we did not conduct a systematic review, we may have missed some evidence relevant to our review questions. In addition, our team did not include patient partners. Conclusions The findings of this review have implications for the management of conflicts of interest not only in patient decision aid development but also in clinical practice guideline development, health and medical research reporting, and health care delivery.

Published: May 2021

Background In 2014, a systematic review found large gaps in the quality of reporting of measures used in 86 published trials evaluating the effectiveness of patient decision aids (PtDAs). The purpose of this study was to update that review. Methods We examined measures of decision making used in 49 randomized controlled trials included in the 2014 and 2017 Cochrane Collaboration systematic review of PtDAs. Data on development of the measures, reliability, validity, responsiveness, precision, interpretability, feasibility, and acceptability were independently abstracted by 2 paired reviewers. Results Information from 273 measures was abstracted, and 109 of these covered the core domains of decision processes ( n = 55) and decision quality including informed choice/knowledge ( n = 48) and values-choice concordance ( n = 12). Very few studies reported data on the performance and clinical sensibility of measures, with reliability (23%) and validity (6%) being the most common. Studies using new measures were less likely to include information about their psychometric performance compared with previously published measures. Limitations The review was limited to reporting of measures in studies included in the Cochrane review and did not consult prior publications. Conclusion There continues to be very little reported about the development or performance of measures used to evaluate the effectiveness of PtDAs in published trials. Minimum reporting standards have been published, and efforts to require investigators to use them are needed.

Published: May 2021

Background In patients with bilobar metastatic liver disease, surgical clearance of both liver lobes may be achieved through multiple-stage liver resections. For patients with extensive disease, a major two-staged hepatectomy consisting of resection of liver segments II and III before right-sided portal vein embolization (PVE) and resection of segments V–VIII may be performed, leaving only segments IV ± I as the liver remnant. Purpose To describe the outcome following right-sided PVE after prior complete resection of liver segments II and III. Material and Methods In this retrospective study, 15 patients (mean age = 60.4 ± 9.3 years) with liver metastases from colorectal cancer (n = 14) and uveal melanoma (n = 1) who were scheduled to undergo a major two-stage hepatectomy, were included. Total liver volume (TLV) and volume of the future liver remnant (FLR) were measured on pre- and postinterventional computed tomography (CT) scans, and standardized FLR volumes (ratio FLR/TLV) were calculated. Patient data were retrospectively analyzed regarding peri- and postinterventional complications, with special emphasis on liver function tests. Results The mean standardized post-PVE FLR volume was 26.9% ± 6.4% and no patient developed hepatic insufficiency after the PVE. Based on FLR hypertrophy and liver function tests, all but one patient were considered eligible for the subsequent right-sided hepatectomy. However, due to local tumor progression, only 9/15 patients eventually proceeded to the second stage of surgery.   Conclusion Right-sided PVE was safe and efficacious in this cohort of patients who had previously undergone a complete resection of liver segments II and III as part of a major staged hepatectomy pathway leaving only segments IV(±I) as the FLR.

Published: May 2021

Background Gadoxetic acid-enhanced magnetic resonance imaging (MRI) has been widely used in clinical practice. However, scientific evidence is lacking for recommending a particular sequence for measuring tumor size. Purpose To retrospectively compare the size of hepatocellular carcinoma (HCC) measured on different gadoxetic acid-enhanced MRI sequences using pathology as a reference. Material and Methods A total of 217 patients with single HCC who underwent gadoxetic acid-enhanced MRI before surgery were included. The size of the HCC was measured by two abdominal radiologists independently on the following sequences: T1-weighted; T2-weighted; b-500 diffusion-weighted imaging (DWI); and arterial, portal venous, transitional, and hepatobiliary phases. Tumor size measured on MRI was compared with pathological size by using Pearson correlation coefficient, independent-sample t test, and Bland–Altman plot. Agreement between two readers was evaluated with intraclass correlation coefficient (ICC). Results Correlation between the MR images and pathology was high for both readers (0.899–0.955). Absolute error between MRI and pathologic assessment was lowest on hepatobiliary phase images for both readers (reader 1, 2.8±4.2 mm; reader 2, 3.2±3.4 mm) and highest on arterial phase images for reader 1 (4.9±4.4 mm) and DWI phase images for reader 2 (5.1±4.9 mm). Absolute errors were significantly different for hepatobiliary phase compared with other sequences for both readers (reader 1, P≤0.012; reader 2, P≤0.037). Inter-reader agreements for all sequence measurements were strong (0.971–0.997). Conclusion The performance of gadoxetic acid-enhanced MRI sequences varied with HCC size, and the hepatobiliary phase may be optimal among these sequences.

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.

Published: May 2021

Objective To evaluate the expression of retinoid-related orphan receptor gamma (RORγ) and its potential role in the prognosis of colon cancer. Methods The Cancer Genome Atlas and GSE117606 were used to evaluate to RORγ levels in colon cancer, and real-time quantitative polymerase chain reaction was applied for validation. UALCAN and MEXPRESS were used to analyze the associations of RORγ expression with clinical parameters. The survival analysis was conducted in GEPIA. Results RORγ expression was significantly lower in colon tumors than in adjacent normal mucosa tissues. RORγ expression was significantly associated with tumor stage, lymph node metastasis, and liver metastasis. The area under the curve for diagnosis was 0.71. Decreased RORγ expression was positively correlated with the incidence of lymphatic invasion, microsatellite instability, the presence of residual tumor, venous invasion, and copy number variation. Overall survival was longer in patients with higher RORγ expression, especially those with microsatellite instability-high features. Methylation analysis revealed that hypermethylation of the RORγ promoter was associated with the colon cancer stage. Conclusions RORγ downregulation could be a potential biomarker for colon cancer, especially for predicting prognosis. Decreased RORγ expression in colon tumor may be associated with promoter hypermethylation.

Objective Clinicians cannot precisely determine the time for withdrawal of ventilation. We aimed to evaluate the performance of driving pressure (DP)×respiratory rate (RR) to predict the outcome of weaning. Methods Plateau pressure (Pplat) and total positive end-expiratory pressure (PEEPtot) were measured during mechanical ventilation with brief deep sedation and on volume-controlled mechanical ventilation with a tidal volume of 6 mL/kg and a PEEP of 0 cmH2O. Pplat and PEEPtot were measured by patients holding their breath for 2 s after inhalation and exhalation, respectively. DP was determined as Pplat minus PEEPtot. The rapid shallow breathing index was measured from the ventilator. The highest RR was recorded within 3 minutes during a spontaneous breathing trial. Patients who tolerated a spontaneous breathing trial for 1 hour were extubated. Results Among the 105 patients studied, 44 failed weaning. During ventilation withdrawal, DP×RR was 136.7±35.2 cmH2O breaths/minute in the success group and 230.2±52.2 cmH2O breaths/minute in the failure group. A DP×RR index >170.8 cmH2O breaths/minute had a sensitivity of 93.2% and specificity of 88.5% to predict failure of weaning. Conclusions Measurement of DP×RR during withdrawal of ventilation may help predict the weaning outcome. A high DP×RR increases the likelihood of weaning failure.
