Abstract
Background
Neuroendocrine tumor (NET) with adrenocorticotropic hormone (ACTH) secretion are very rare. To our knowledge, no follow-up study is published for ACTH-secreting NET, regardless of the primary site, to show second occurrence of tumor after a long follow-up, following resection of primary tumor.

Case presentation
Here, we describe a 49-year-old-man with cushingoid feature, drowsiness and quadriparesis came to emergency department at December 2005. Laboratory tests revealed hyperglycemia, metabolic alkalosis, severe hypokalemia, and chemical evidence of an ACTH-dependent hypercortisolism as morning serum cortisol of 57 μg /dL without suppression after 8 mg dexamethasone suppression test, serum ACTH level of 256 pg/mL, and urine free cortisol of > 1000 μg /24 h. Imaging showed only bilateral adrenal hyperplasia, without evidence of pituitary adenoma or ectopic ACTH producing tumors. Importantly, other diagnostic tests for differentiating Cushing disease (CD) from ectopic ACTH producing tumor, such as inferior petrosal sinus sampling (IPSS), corticotropin releasing hormone (CRH) stimulation test, octreotide scan or fluorodeoxyglucose (FDG)-positron emission tomography (PET) scan were not available in our country at that time. Therefore, bilateral adrenalectomy was performed that led to clinical and biochemical remission of hypercortisolism and decreased ACTH level to < 50 pg/mL, findings suggestive of a primary focus of NET in adrenal glands. After 11 years uncomplicated follow up, the ACTH level elevated up to 341 pg/mL and re-evaluation showed a 2 cm nodule in the middle lobe of the right lung. Surgical excision of the pulmonary nodule yielded a carcinoid tumor with positive immunostaining for ACTH; leading to decrease in serum ACTH level to 98 pg/mL. Subsequently after 7 months, serum ACHT levels rose again. More investigation showed multiple lung nodules with metastatic bone lesions accompanied by high serum chromogranin level (2062 ng/mL), and the patient managed as a metastatic NET, with bisphosphonate and somatostatin receptor analogues.

Conclusion
This case of surgically-treated NET showing a secondary focus of carcinoid tumor after one decade of disease-free follow-up emphasizes on the importance of long-term follow-up of ACTH-secreting adrenal NET.

Abstract
Background
Traditional Chinese medicine (TCM) has gained increasing acceptance and popularity by the global community. The current study aimed to investigate self-reported evaluations of learning TCM and opinions about TCM courses among undergraduate international students majoring in conventional medicine at a university in China.

Methods
A cross-sectional survey was conducted at the Zhejiang University School of Medicine. A self-reported questionnaire was administered to international undergraduates who were enrolled in the TCM course during the 2018 and 2019 academic years (n = 157). The course employed a student-centered, multiform learning model. Demographic data and self-reported evaluations of TCM learning background and TCM learning course were obtained to conduct the analysis.

Results
A total of 133 students responded to the questionnaire. Among the respondents, 21.0% had some TCM-related knowledge, and 51.1% were interested in learning TCM before the course. Ninety-six students (85.7%) were from Asia. Students from Thailand showed significantly more interest in learning TCM than did students from other Asian countries (p = 0.025). After the course, 77.2% of students agreed that the course had brought about many benefits, 86.4% were satisfied with the course content, and 77.3% were satisfied with the teaching method. Students expressed their willingness to further learn acupuncture and to obtain more skilled practice through more visualized learning methods.

Conclusions
The majority of the international students we surveyed agreed that the TCM course improved their interest in and understanding of TCM. It is thus suggested that TCM education should be directed toward students’ learning barriers and needs.

AbstractBackgroundEndocrinopathic, or hyperinsulinaemia-associated laminitis (HAL) is a common and debilitating equine foot disease, and although no pharmacological treatments are registered, several are under development. To evaluate the effect of such treatments, an accurate and consistent method is needed to track the clinical signs of laminitis over time, and the natural history of the disease, in terms of a ‘normal’ pattern of improvement, needs to be understood. This study examined the improvement pattern in clinical cases of naturally-occurring HAL subjected to a range of best-practice interventions, using two different scoring methods. Eighty horses and ponies with suspected HAL were enrolled in a study conducted at 16 veterinary practices across Germany. The severity of laminitis was assessed by independent veterinarians using both the traditional Obel method and a modified Obel method developed by Meier and colleagues. Assessments were made on the day of diagnosis (d 0), then on days 4, 9, 14, 25 and 42 during the intervention period. Pain medications were withheld for 24 h prior to clinical examination in all cases.ResultsTime to marked improvement from laminitis varied between individuals, but was difficult to monitor accurately using the Obel method, with the median grade being 2/4 on days 0 and 4, then 0/4 from d 9 onwards. More subtle changes could be identified using the Meier method, however, and the median scores were seen to follow the form of an exponential decay model in most horses, improving from 8/12 on d 0, to 0/12 on d 25. Within this composite scoring method, considerable variation was observed in the rate of improvement of individual clinical signs, with the average time taken for each sign to reach a median score of 0 ranging from 4 days (foot lift and weight shifting) to 25 days (gait when turned in a circle) across all 80 horses.ConclusionsThe Meier method provides a reliable and consistent method for monitoring the clinical status of horses with HAL, and despite the variability, the pattern of improvement described here should provide a useful benchmark against which individual cases and new treatments can be assessed.

AbstractBackgroundChronic renin-angiotensin-aldosterone system (RAAS) activation in course of heart diseases contributes to cardiac remodeling and heart failure. Myxomatous mitral valve disease (MMVD) is characterized by different stages of severity and trend of RAAS activity during the course of the disease is still uncertain. The urinary aldosterone-to-creatinine ratio (UAldo:C) has been proven to reflect RAAS activation in dogs and might be a useful marker in monitoring therapy and disease progression, but data about this parameter need to be expanded. The objective of this study was to evaluate the UAldo:C in healthy dogs and dogs with naturally occurring MMVD, and to investigate the relationships between this parameter and clinical, echocardiographic and laboratory variables.ResultsThe study population consisted of 149 dogs: 49 healthy and 100 MMVD dogs (45 stage B1, 13 stage B2 and 42 stage C). Urinary aldosterone-to-creatinine ratio was not significantly different among healthy and MMVD dogs of any stages. Breed, sex and age showed a significant impact on UAldo:C. In particular, Chihuahua and Cavalier King Charles spaniel showed significantly higher UAldo:C than other breeds, as well as intact females than other genders. In stage C dogs, UAldo:C appeared to be increased by spironolactone and was positively associated with furosemide dose (P = 0.024). Aldosterone breakthrough (ABT) appeared to occur in 36% (8/22) of stage C dogs not receiving spironolactone. A significant positive association between UAldo:C and left atrium-to-aortic root ratio (LA/Ao) was found.ConclusionsIndividual factors such as breed, sex and age appeared to influence UAldo:C, and therapy seemed to add further variability. In the light of these results, comparing the UAldo:C of a single patient with a population-based reference value might lead to wrong interpretations and an individual monitoring should be considered. The prevalence of ABT in the present study (36%) was in line with those previously reported. However, due to the high individual variability of UAldo:C found in the study, even this result should be re-evaluated in the setting of an individual longitudinal approach. The positive association between UAldo:C and LA/Ao supports the mutual relationship between RAAS and cardiac remodeling.

AbstractBackgroundHibernation is a physiological and behavioural adaptation that permits survival during periods of reduced food availability and extreme environmental temperatures. This is achieved through cycles of metabolic depression and reduced body temperature (torpor) and rewarming (arousal). Rewarming from torpor is achieved through the activation of brown adipose tissue (BAT) associated with a rapid increase in ventilation frequency. Here, we studied the rate of rewarming in the European hamster (Cricetus cricetus) by measuring both BAT temperature, core body temperature and ventilation frequency.ResultsTemperature was monitored in parallel in the BAT (IPTT tags) and peritoneal cavity (iButtons) during hibernation torpor-arousal cycling. We found that increases in brown fat temperature preceded core body temperature rises by approximately 48 min, with a maximum re-warming rate of 20.9℃*h-1. Re-warming was accompanied by a significant increase in ventilation frequency. The rate of rewarming was slowed by the presence of a spontaneous thoracic mass in one of our animals. Core body temperature re-warming was reduced by 6.2℃*h-1and BAT rewarming by 12℃*h-1. Ventilation frequency was increased by 77% during re-warming in the affected animal compared to a healthy animal. Inspection of the position and size of the mass indicated it was obstructing the lungs and heart.ConclusionsWe have used a minimally invasive method to monitor BAT temperature during arousal from hibernation illustrating BAT re-warming significantly precedes core body temperature re-warming, informing future study design on arousal from hibernation. We also showed compromised re-warming from hibernation in an animal with a mass obstructing the lungs and heart, likely leading to inefficient ventilation and circulation.

Abstract
Background
Consistent use of insecticide-treated nets (ITNs) and intermittent preventive treatment in pregnancy (IPTp) have been recommended as cost-effective interventions for malaria prevention during pregnancy in endemic areas. However, the coverage and utilization of these interventions during pregnancy in sub-Saharan Africa is still suboptimal. This study aimed to determine the uptake of IPTp and ITNs and associated factors among women during their recent pregnancy in Eastern Uganda.

Methods
This was a cross-sectional study conducted among 2062 women who had delivered within the last 12 months prior to the start of the study in three districts of Eastern Uganda. The primary outcomes were consistent ITN use and optimal uptake (at least 3 doses) of IPTp. A modified Poisson regression was used to examine the association between consistent ITN use and the uptake of optimal doses of IPTp with independent variables. Data were analysed using Stata 14 software.

Results
The level of uptake of IPTp3 (at least three doses) was 14.7%, while IPTp2 (at least two doses) was 60.0%. The majority (86.4%) of mothers reported regularly sleeping under mosquito nets for the full duration of pregnancy. Uptake of IPTp3 was associated with engaging in farming (adjusted PR = 1.71, 95% CI [1.28–2.28]) or business (adjusted PR = 1.60, 95% CI [1.05–2.44]), and attending at least 4 antenatal care (ANC) visits (adjusted PR = 1.72, 95% CI [1.34–2.22]). On the other hand, consistent ITN use was associated with belonging to the fourth wealth quintile (adjusted PR = 1.08, 95% CI [1.02–1.14]) or fifth wealth quintile (adjusted PR = 1.08, 95% CI [1.02–1.15]), and attending at least 4 ANC visits (adjusted PR = 1.07, 95% CI [1.03–1.11]).

Conclusion
Uptake of IPTp3 and consistent ITN use during pregnancy were lower and higher than the current Ugandan national targets, respectively. Study findings highlight the need for more efforts to enhance utilization of ANC services, which is likely to increase the uptake of these two key malaria preventive measures during pregnancy.

Abstract
Background
Research has demonstrated that therapeutic interventions based on the self-efficacy theory produce positive outcomes for people who exhibit addictive behaviors, such as alcohol and drug use. Several questionnaires based on self-efficacy theory have been developed to evaluate the extent to which intervention programs can modify behavior. The present study describes the psychometric properties of the Farsi version of the Drug Abstinence Self-Efficacy Scale (DASES).

Design and methods
The forward–backward approach was employed to translate the DASES from English into Farsi. A cross-sectional study was conducted, and the psychometric properties of the Farsi version of the DASES were measured. Using a cluster sampling method, 400 male people who use drugs aged 20 years or older were selected from 10 addiction treatment clinics in Mazandaran, Iran. The internal consistency and test–retest methods were used to measure the reliability of the DASES. Face and content validity were measured, and the construct validity of the DASES was assessed through both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The data were analyzed using SPSS and AMOS.

Results
The results of the EFA indicated a four-factor solution for the DASES that accounted for 64.72% of the observed variance. The results obtained from the CFA demonstrated that the data fitted the model: the relative chi square (× 2/df) equaled 1.99 (p < 0.001), and the root mean square error of approximation equaled 0.071 (90% CI = 0.059–0.082). All the comparative indices of the model were equal to or greater than 0.90 (0.91, 0.93, 0.94, 0.93, and 0.90, respectively). The Cronbach’s alpha ranged from 0.90 to 0.93, proving a satisfactory reliability. Additionally, the intraclass correlation coefficient ranged from 0.75 to 0.98, which is an acceptable result.

Conclusions
This study’s results show that the Iranian version of the DASES has good psychometric properties and is appropriate for assessing substance use behaviors among Iranian addicted persons.

AbstractThis manuscript reports the Brazilian Diabetes Society Position Statement for insulin adjustments based on trend arrows observed in continuous glucose monitoring systems. The Brazilian Diabetes Society supports the utilization of trend arrows for insulin dose adjustments in patients with diabetes on basal-bolus insulin therapy, both with multiple daily insulin doses or insulin pumps without closed-loop features. For those on insulin pumps with predictive low-glucose suspend feature, we suggest that only upward trend arrows should be used for adjustments. In this paper, tables for insulin adjustment based on sensitivity factors are provided and strategies to optimize the use of trend arrows in clinical practice are discussed.

AbstractBackgroundThe global increase in the utilization of non - prescribed antibiotics (NPA), is concerning, with high persistence within the low and middle-income countries (LMICs). With a negative impact on the health of individuals and communities the use of NPA paves the way to the propagation of superbugs that potentially predisposes to changes in bacterial resistance patterns, antibiotic resistance (AR) and antimicrobial resistance (AMR). This study aimed at estimating through a systematic review and meta-analysis, the prevalence of NPA utilisation and describe its primary sources in LMICs.MethodsThe study is a systematic review and meta-analysis which study protocol was registered in PROSPERO (CRD42017072954). The review used The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The studies searched in databases were deemed eligible if reported evidence of practices of self-medication with antibiotics (SMA) and the prevalence of NPA utilisation within adult participants from LMICs, published between 2007 to 2017. The pooled analyses were carried out using Meta XL statistical software. The pooled prevalence was calculated with a 95% confidence interval (CI). The risk of bias of the included studies was assessed using the Quality in Prognosis Studies (QUIPS) tool.ResultsThe review included a total of 11 cross-sectional studies, involving 5080 participants and conducted in LMICs from Asia (India, Laos, Nepal, Pakistan, Sri Lanka and Yemen), Latin America (Guatemala), Africa (Nigeria). All studies reported existing practices of SMA, with reported prevalence ranging from 50% to 93,8%. The pooled prevalence of SMA was 78% (95% CI: 65–89%). The main sources of NPA were; pharmacies, family and friends, old prescriptions, home cabinet and leftover antibiotics.ConclusionThis study revealed a high prevalence of utilisation of NPA in the studied LMICs, these were found to be twice as high in women than men and those participants aged between 18 and 40 years old. The review suggests f considering broader qualitative and comprehensive contextuallized research to better understand the nuances of NPA use. These would be benefitial to uncover uncover gray areas, inform decisions, support the (re) design and implementation of multifaceted interventions towards antibiotic stewardship and conservancy in LMICs.

AbstractBackgroundDespite the significant reductions in under-five mortality, campylobacteriosis has emerged as one of the most common causative agents of bacterial foodborne gastroenteritis in humans. We performed this systematic review and meta-analysis to estimate the pooled prevalence of Campylobacter species and associated risk factors among children less than 5 years of age in Ethiopia.MethodsA systematic search was conducted on PubMed, Web of Science, EMBASE, Google Scholar and the Cochrane Library. All identified observational studies reporting the prevalence and determinants of diarrhea among children under 5 years of age in Ethiopia were included. Two authors independently extracted data and analyzed them using STATA Version 13 statistical software. A random-effects model was computed to estimate the pooled prevalence and the associations between determinant factors and campylobacteriosis.ResultsOut of 166 papers reviewed, 8 studies fulfilled the inclusion criteria and were included in the meta-analysis. The pooled prevalence of Campylobacter species among children under 5 years of age in Ethiopia was 10% (95% CI: 7, 13). Contact with domestic animals (OR: 3.2, 95% CI: 2.0, 5.1), illiterate mothers (OR: 2.1, 95% CI: 1.1, 3.8), consumption of animal products (OR: 1.7, 95% CI: 0.7, 4.5), and status of mothers’ personal hygiene (OR: 1.1, 95% CI: 0.7, 1.8) were significantly associated with the prevalence of Campylobacter species.ConclusionIn our study, Campylobacter species among children under 5 years of age in Ethiopia were significantly high. Contact with domestic animals, illiterate mothers and consumption of animal products were significantly associated with prevalence of Campylobacter species
