Role of hepatokines in non-alcoholic fatty liver disease

Abstract

Non-alcoholic fatty liver disease (NAFLD) is closely associated with metabolic diseases like type 2 diabetes and obesity. In recent decades, accumulating evidence has revealed that the hepatokines, proteins mainly secreted by the liver, play important roles in the development of NAFLD by acting directly on the lipid and glucose metabolism. As a member of organokines, the hepatokines establish the communication between the liver and the adipose, muscular tissues. In this review, we summarize the current understanding of the hepatokines and how they modulate the pathogenesis of metabolic disorders especially NAFLD.

A summary of the evidence and evaluation of the effectiveness of nonpharmacological interventions for mild cognitive impairment

Abstract

Objective

To summarize and evaluate the evidence of guidelines and systematic reviews (SRs) of nonpharmacological interventions for mild cognitive impairment (MCI) to support the development of future guidelines and clinical decisions for MCI patients.

Methods

Scottish Intercollegiate Guideline Network (SIGN), National Institute for Health and Clinical Excellence (NICE), American Academy of Neurology (AAN), Registered Nurses Association of Ontario (RNAO), Web of Science, PubMed, Cochrane Library, CNAHL, VIP, China National Knowledge Infrastructure (CNKI), and Wanfang Database were searched for relevant publications, including guidelines and SRs, from January 2014 to March 2019. Two authors independently screened articles, extracted data, and assessed the publications for adherence to the inclusion criteria. Appraisal of Guidelines for Research and Evaluation (AGREE II) was used to assess the quality of the guidelines, and Assessment of Multiple Systematic Reviews (AMSTAR 2) was used to assess the quality of SRs. In addition, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of outcomes.

Results

Thirty-two articles were retrieved, including 1 guideline and 31 SRs. Fourteen SRs of physical exercise for MCI, six articles describing cognitive interventions, four articles describing acupuncture, and seven articles assessing dietary interventions (including four articles employing a Mediterranean diet, one article using vitamin B supplementation, and two articles assessing the effects of tea, coffee, and caffeine) were included. The quality of the articles was very low for 4 (13%), low for 10 (32%), and moderate for 17 (55%).

Conclusions

Based on the evidence available to date, nonpharmacological interventions may improve the current cognitive function of persons with MCI. In particular, physical exercise, cognitive interventions, and acupuncture exerted promising effects. However, due to the limited number and quality of the included publications, additional high-quality reviews are needed to further confirm.

Walled-off peripancreatic fluid collections in Asian population: Paradigm shift from surgical and percutaneous to endoscopic drainage

Abstract

Background and Objectives

Drainage of symptomatic walled-off peripancreatic fluid collections (WPFCs) can be achieved by endoscopic, percutaneous, and surgical techniques. The aim of this study was to determine the current trends in management of WPFCs and the outcome of such modalities in Asian population.

Methods

In this retrospective analysis, all patients diagnosed with pancreatitis from 2013 to 2016 in King Chulalongkorn Memorial Hospital, Bangkok, Thailand, were analyzed. Relevant clinical data of all patients with peripancreatic fluid collections (PFCs) was reviewed. Clinical success was defined as improvement in symptoms after drainage.

Results

Of the total 636 patients with pancreatitis, 72 (11.3%) had WPFCs, of which 55 (8.6%) and 17 (2.7%) had pancreatic pseudocyst (PP) and walled-off necrosis (WON), respectively. The commonest etiologies of WPFCs were alcohol (38.9%) and biliary stone (29.2%). Post-procedure and pancreatic tumor related pancreatitis was found in 8.3% and 6.9% patients, respectively. PP was more common in chronic (27.8%) than acute (5.5%) pancreatitis. Of the 72 patients with WPFCs, 31 (43.1%) had local complications. Supportive, endoscopic, percutaneous, and surgical drainage were employed in 58.3%, 27.8%, 8.3%, and 5.6% with success rates being 100%, 100%, 50%, and 100%, respectively. Complications that developed after percutaneous drainage included bleeding at procedure site (n = 1), infection of PFC (n = 1), and pancreatic duct leakage (n = 1).

Conclusion

Over the past few years, endoscopic drainage has become the most common route of drainage of WPFCs followed by percutaneous and surgical routes. The success rate of endoscopic route is better than percutaneous and comparable to surgical modality.

Assessment of subclinical hypothyroidism for a clinical score and thyroid peroxidase antibody: a comparison with euthyroidism grouped by different thyroid-stimulating hormone levels

Abstract

Background

Subclinical hypothyroidism (SCH) might have many symptoms of hypothyroidism. The controversy appears to lower the level of thyroid-stimulating hormone (TSH) and group subjects with TSH of more than 3 or even 2.5 mIU/L as SCH subjects.

Objectives

To assess SCH subjects both clinically using Zulewski clinical score and biochemically and to evaluate whether the euthyroid subjects with high-normal TSH (HNT) have any clinical symptom or subnormal biochemical finding.

Methods

A prospective cross-sectional study of 233 subjects, 67 with SCH and 166 euthyroidism, was conducted. Euthyroid subjects were divided according to the level of TSH as HNT (>2.5 mIU/L) and low-normal TSH (0.5–2.5 mIU/L). The subjects were examined for clinical feature including Zulewski clinical score and biochemical evaluations including thyroid peroxidase antibody (TPO-Ab) titer. The comparisons between groups were assessed using independent sample t test, and correlations between variables were evaluated using Pearson correlation.

Results

A significantly higher clinical score and higher frequencies of symptoms were found in the SCH group compared to the euthyroid group. The most frequent symptom was fatigue. Euthyroid subjects with HNT were found to have higher TPO-Ab titers than those with low-normal TSH, P < 0.05. The Zulewski clinical score was positively correlated with TSH and TPO-Ab titer but negatively correlated with the FT4 level, P < 0.05.

Conclusions

Zulewski clinical score is higher in SCH subjects compared to euthyroid subjects and can aid in assessing SCH subjects. A significant correlation exists between Zulewski clinical score and each of the TSH, FT4, and TPO-Ab titer levels. The frequency of TPO-Ab positivity is high in SCH. Additionally, euthyroid with higher TSH levels has higher level of TPO-Ab titer but not higher clinical score.

Clinical outcomes and surgical preferences for breast-conserving surgery and mastectomy: a propensity score-matched analysis

Abstract

Background

While numerous randomized controlled trials have demonstrated long-term survival rates for patients with early-stage breast cancer treated with breast-conserving surgery (BCS) comparable to mastectomy, the latter remains the most prevalent surgical option to treat early-stage breast cancer in Thailand.

Objectives

To investigate the potential determinants affecting the decision on selecting BCS or mastectomy for the treatment of early-stage breast cancer and to compare the disease-free survival and overall survival between the treatments using a propensity score-matched analysis.

Methods

Patients diagnosed nonmetastatic breast cancer at the Queen Sirikit Breast Cancer Center from January 2006 to December 2015, were retrospectively identified and grouped intro patients who received BCS or mastectomy. After propensity score matching, 356 BCS and 209 mastectomy patients were identified, and statistical analysis was conducted to determine treatment selection factors and compare disease-free and overall survival.

Results

Disease-free survival and overall survival in months comparing BCS and mastectomy were not statistically different with P values of 0.11 and 0.77, respectively. Determinants of treatment selection found that younger age, surgeon preference, smaller tumor size, and lower tumor grade were statistically significant factors in the selection of BCS over mastectomy. The majority of surgeons had a preference for one treatment over the other (P < 0.001).

Conclusion

The outcome of BCS is comparable to mastectomy in early-stage breast cancer patients. Key determinants affecting the selection of treatment were identified to be patient age, characteristics of the tumor, and surgeon’s preference.

Common orthopedic problems in the neonate: a comparative study of 2 periods at a tertiary-care hospital

Abstract

Background

In 1975, King Chulalongkorn Memorial Hospital (KCMH) in Bangkok, Thailand, published data on common orthopedic problems in neonates.

Objectives

To determine the more recent incidence of these conditions and to compare the results with those reported 40 years ago by KCMH. The data were also compared with a recent report from Siriraj Hospital.

Methods

We reviewed medical records of newborn infants from 2012 to 2016, all of whom were born in KCMH with deformities of upper and lower extremities or other birth-related injuries. The cases were grouped according to International Classification of Diseases, 10th edition. The incidence of common neonatal orthopedic problems was calculated as cases per 1,000 live births and compared, using a chi-squared test, with the earlier data from KCMH and with the data recently reported by Siriraj hospital.

Results

Of the 24,825 live births, 54% were male and 46% were female. The average birth weight was 3,052.2 ± 516.1 g (range, 535–5,320 g) for infants. The most common deformity was postural clubfoot, followed by calcaneovalgus and hip dysplasia, with incidences of 1.37, 0.93 and 0.52 per 1,000 live births, respectively. The incidence of calcaneovalgus, metatarsus adductus, and clubfoot was lower than in the 1975 study and in the report from Siriraj. In all 3 studies, the incidence of birth-related injury was similar and clavicular fracture was the most common, with a rate of 1.3/1,000 live births.

Conclusion

The incidence of common neonatal orthopedic problems varies among institutions. Birth-related injury is a major challenge. The results may be utilized as updated data and as a starting point for parental education.

Conservative surgical management for immediate postpartum hemorrhage

Abstract

Background

Conservative surgical management for postpartum hemorrhage (PPH), such as balloon tamponade, uterine compression suture, and uterine artery ligation, has the benefit of preserving reproductive function.

Objectives

To assess the efficacy and subsequent pregnancy outcome of conservative surgical management for patients with immediate PPH.

Methods

Medical records of patients who had PPH between January 2011 and December 2016 were reviewed. Conservative surgical management included B-Lynch uterine compression suture, Bakri balloon tamponade, and uterine artery ligation. The treatments were considered successful if patients did not require subsequent hysterectomy. Perioperative complications and subsequent pregnancy outcomes were recorded.

Results

Of 30,271 deliveries, 669 patients experienced PPH or 2.2% of total deliveries. Sixty-one patients (9.1%) did not respond to medical treatment with various uterotonic agents. Hysterectomy was selected initially in 30 patients. Conservative surgical management was performed in 31 patients: 15 Bakri balloon tamponade, 13 uterine compression suture, and 3 uterine artery ligation. There were 3 patients who failed Bakri balloon tamponade and proceeded to perform uterine compression suture with successful outcome. The success rates for conservative surgical treatment were 66.7%, 75%, and 66.7%, respectively. All patients who had successful conservative surgical management resumed normal menstruation. Three out of 11 patients (27.3%) who desired subsequent pregnancy were able to conceive and carry out a viable pregnancy.

Conclusion

Conservative surgical management has acceptable success rates for controlling intractable immediate PPH. Implementation of such procedures should be done to preserve fertility and decrease maternal morbidity and mortality.

Distinguishing magnetic resonance imaging features between idiopathic hypertrophic pachymeningitis and secondary hypertrophic pachymeningitis

Abstract

Background

Hypertrophic pachymeningitis (HP) is a rare chronic inflammatory disorder characterized by marked fibrous thickening of the cerebral and/or spinal dura mater. This condition is caused by infection, inflammation, autoimmune disorder, neoplasms, or idiopathic. Magnetic resonance imaging (MRI) may play an important role in differentiating idiopathic HP from secondary HP, may avoid unnecessarily invasive dural biopsy, and prompt specific treatment.

Objective

To determine the specific MRI findings for differentiation between idiopathic HP and secondary HP.

Method

A total of 34 patients underwent MRI of the brain and cervical spine from January 2003 to December 2015. In all, 23 patients were diagnosed idiopathic HP and 11 patients were secondary HP. Demographic data and imaging findings reveal the following: configuration, thickness, signal intensity on T1-weighted image (T1WI), T2-weighted image (T2WI), and enhancement pattern of the lesions. The data were analyzed by T-test and Fisher’s exact test.

Result

Secondary HP were significantly located at anterior and middle cranial fossa (P = 0.033). There is no significant difference of lesions in configurations, T1 and T2 signal intensity and patterns of enhancement. There was significant and exclusive difference in T2 hypointense/dark intensity and homogeneous enhancement in idiopathic HP (75%, P = 0.044).

Conclusions

MRI may play a complimentarily important role in distinguishing idiopathic HP from secondary HP. Idiopathic HP is probably preferred diagnosis in the lesions with T2-rim pattern and T2 hypointense/dark intensity with homogeneous enhancement.
