Etiological aspects of intragastric bezoars and its associations to the gastric function implications

Rationale: Intragastric bezoar is a stony mass found trapped in the stomach, though it can occur in other locations of the gastro-intestinal tract. The etiology of intragastric bezoar is multifactorial, includes certain risk factors and predisposing factors such as coexisting medical disorders, anatomic abnormalities, and gastric motility disorders, which contribute to the development of intragastric bezoar. Patient concerns: In this report, we present a rare case of intragastric bezoar with epigastric pain after prolonged consumption of jujubes. To our knowledge, this is the first case of intragastric bezoar to be reported after jujubes ingestion. Diagnoses: An upper gastrointestinal (GI) endoscopy performed which revealed an 8 × 5-cm intragastric diospyrobezoar with an adjacent necrotic pressure ulcer of size 0.8 × 0.5-cm without signs of bleeding. Interventions: For therapeutic intervention, Coca-Cola ingestion and lithotripsy were applied. Outcomes: The therapeutic course was uneventful. There was no recurrence during 1-year follow-up. Lessons: In our literature, jujube emerged as a new player. A bezoar composed of unripened fruit content in the stomach, could be the cause of chronic abdominal pain, dyspepsia, gastric reflux or heartburn. Moreover, this study provides a detailed overview of recently published literature regarding intragastric manifestations of bezoar, etiological factors, diagnostic and therapeutic approaches.
Validation of the Mental Health Continuum‐Short Form and the dual continua model of well‐being and psychopathology in an adult mental health setting

Abstract Objective The growing evidence for the dual continua model of psychopathology and well‐being has important implications for measuring outcomes in mental health care. The aim of the current study is to validate a measure of well‐being as well as the dual continua model in adults with mood, anxiety, personality, and developmental disorders. Methods 472 adult psychiatric outpatients filled out the Mental Health Continuum‐Short Form (MHC‐SF) and the Outcome Questionnaire before start of treatment. Results Confirmatory factor analyses (CFA) confirmed the three‐factor structure of emotional, psychological, and social well‐being of the MHC‐SF. The dual continua model had the best fit in the complete sample and the different diagnostic groups. Conclusion The MHC‐SF is a reliable and valid instrument to measure well‐being in the psychiatric population. Although relatively high correlations between psychopathology and well‐being exist, the results underline the importance to measure well‐being in addition to psychopathology in mental health care.
Effects of urban stormwater and iron‐enhanced sand filtration on Daphnia magna and Pimephales promelas

Urban stormwater is an important but incompletely characterized contributor to surface‐water toxicity. The present study used 5 bioassays of 2 model organisms (Daphnia magna and fathead minnow, Pimephales promelas) to investigate stormwater toxicity and mitigation by full‐scale iron‐enhanced sand filters (IESFs). Stormwater samples were collected from major stormwater conveyances and full‐scale IESFs during 4 seasonal events (winter snowmelt and spring, early summer, and late summer rainfalls) and analyzed for a diverse range of contaminants of emerging concern including pharmaceuticals, personal care products, industrial chemicals, and pesticides. Concurrently, stormwater samples were collected for toxicity testing. Seasonality appeared more influential and consistent than site type for most bioassays. Typically, biological consequences were least in early summer and greatest in late summer and winter. In contrast with the unimproved and occasionally reduced biological outcomes in IESF‐treated and late summer samples, water chemistry indicated that numbers and total concentrations of detected organic chemicals, metals, and nutrients were reduced in late summer and in IESF‐treated stormwater samples. Some potent toxicants showed more specific seasonality (e.g., high concentrations of polycyclic aromatic hydrocarbons and industrial compounds in winter, pesticides in early summer and spring, flame retardants in late summer), which may have influenced outcomes. Potential explanations for insignificant or unexpected stormwater treatment outcomes include confounding effects of complex stormwater matrices, IESF nutrient removal, and, less likely, unmonitored toxicants.

Ogilvie's syndrome: management and outcomes

Abstract Ogilvie's syndrome, also known as acute colonic pseudo-obstruction, refers to pathologic dilation of the colon without underlying mechanical obstruction, occurring primarily in patients with serious comorbidities. Diagnosis of Ogilvie's syndrome is based on clinical and radiologic grounds, and can be treated conservatively or with interventions such as acetylcholinesterase inhibitors (such as neostigmine), decompressive procedures including colonoscopy, and even surgery. Based on our clinical experience we hypothesized that conservative management yields similar, if not superior, results to interventional management. Therefore, we retrospectively examined all patients over the age of 18 with Ogilvie's syndrome who presented to the Medical University of South Carolina (MUSC). The diagnosis of Ogilvie's syndrome was confirmed by clinical criteria, including imaging evidence of colonic dilation ≥9 cm. Patients were divided and analyzed in 2 groups based on management: conservative (observation, rectal tube, nasogastric tube, fluid resuscitation, and correction of electrolytes) and interventional (neostigmine, colonoscopy, and surgery). Use of narcotics in relation to maximal bowel size was also analyzed. Over the 11-year study period (2005–2015), 37 patients with Ogilvie's syndrome were identified. The average age was 67 years and the average maximal bowel diameter was 12.5 cm. Overall, 19 patients (51%) were managed conservatively and 18 (49%) underwent interventional management. There was no significant difference in bowel dilation (12.0 cm vs 13.0 cm; P = .21), comorbidities (based on the Charlson Comorbidity Index (CCI), 3.2 vs 3.4; P = . 74), or narcotic use (P = .79) between the conservative and interventional management groups, respectively. Of the 18 patients undergoing interventional management, 11 (61%) had Ogilvie's-syndrome-related complications compared to 4 (21%) of the 19 patients in the conservative management group (P < .01). There was no difference in overall length of stay in the 2 groups. Two patients, one in each group, died from complications unrelated to their Ogilvie's syndrome. We conclude that Ogilvie's syndrome, although uncommon, and typically associated with severe underlying disease, is currently associated with a low inpatient mortality. While interventional management is often alluded to in the literature, we found no evidence that aggressive measures lead to improved outcomes.
The role of mitochondria in anchoring dynein to the cell cortex extends beyond clustering the anchor protein

ABSTRACT Organelle distribution is regulated over the course of the cell cycle to ensure that each of the cells produced at the completion of division inherits a full complement of organelles. In yeast, the protein Num1 functions in the positioning and inheritance of two essential organelles, mitochondria and the nucleus. Specifically, Num1 anchors mitochondria as well as dynein to the cell cortex, and this anchoring activity is required for proper mitochondrial distribution and dynein-mediated nuclear inheritance. The assembly of Num1 into clusters at the plasma membrane is critical for both of its anchoring functions. We have previously shown that mitochondria drive the assembly of Num1 clusters and that these mitochondria-assembled Num1 clusters serve as cortical attachment sites for dynein. Here we further examine the role for mitochondria in dynein anchoring. Using a GFP-αGFP nanobody targeting system, we synthetically clustered Num1 on eisosomes to bypass the requirement for mitochondria in Num1 cluster formation. Utilizing this system, we found that mitochondria positively impact the ability of synthetically clustered Num1 to anchor dynein and support dynein function even when mitochondria are no longer required for cluster formation. Thus, the role of mitochondria in regulating dynein function extends beyond simply concentrating Num1; mitochondria likely promote an arrangement of Num1 within a cluster that is competent for dynein anchoring. This functional dependency between mitochondrial and nuclear positioning pathways likely serves as a mechanism to order and integrate major cellular organization systems over the course of the cell cycle.
What's in a tide pool? Just as much food web network complexity as in large open ecosystems

Understanding the fundamental laws that govern complex food web networks over large ecosystems presents high costs and oftentimes unsurmountable logistical challenges. This way, it is crucial to find smaller systems that can be used as proxy food webs. Intertidal rock pool environments harbour particularly high biodiversity over small areas. This study aimed to analyse their food web networks to investigate their potential as proxies of larger ecosystems for food web networks research. Highly resolved food webs were compiled for 116 intertidal rock pools from cold, temperate, subtropical and tropical regions, to ensure a wide representation of environmental variability. The network properties of these food webs were compared to that of estuaries, lakes and rivers, as well as marine and terrestrial ecosystems (46 previously published complex food webs). The intertidal rock pool food webs analysed presented properties that were in the same range as the previously published food webs. The niche model predictive success was remarkably high (73–88%) and similar to that previously found for much larger marine and terrestrial food webs. By using a large-scale sampling effort covering 116 intertidal rock pools in several biogeographic regions, this study showed, for the first time, that intertidal rock pools encompass food webs that share fundamental organizational characteristics with food webs from markedly different, larger, open and abiotically stable ecosystems. As small, self-contained habitats, intertidal rock pools are particularly tractable systems and therefore a large number of food webs can be examined with relatively low sampling effort. This study shows, for the first time that they can be useful models for the understanding of universal processes that regulate the complex network organization of food webs, which are harder or impossible to investigate in larger, open ecosystems, due to high costs and logistical difficulties.
Circulating PIWI-Interacting RNAs piR-5937 and piR-28876 Are Promising Diagnostic Biomarkers of Colon Cancer

Background: The early detection of colon cancer is one of the main prerequisites for successful treatment and mortality reduction. Circulating PIWI-interacting RNAs (piRNA) were recently identified as novel promising biomarkers. The purpose of the study was to assess the profiles of piRNAs in blood serum of colon cancer patients with the aim to identify those with high diagnostic potential. Methods: Blood serum samples from 403 colon cancer patients and 276 healthy donors were included in this 3-phase biomarker study. Large-scale piRNA expression profiling was performed using Illumina small RNA sequencing. The diagnostic potential of selected piRNAs was further validated on independent training and validation sets of samples using RT-qPCR. Results: In total, 31 piRNAs were found to be significantly deregulated in serum of cancer patients compared with healthy donors. Based on the levels of piR-5937 and piR-28876, it was possible to differentiate between cancer patients and healthy donors with high sensitivity and specificity. Moreover, both piRNAs exhibited satisfactory diagnostic performance also in patients with stage I disease and enabled detection of colon cancer with higher sensitivity than currently used biomarkers CEA and CA19-9. Finally, the expression of analyzed piRNAs in blood restored significantly 1 month after the surgical resection. Conclusions: Based on our findings, piRNAs are abundant in human blood serum. Furthermore, their levels in colon cancer have been observed to be significantly deregulated. However, their involvement in carcinogenesis must be further established. Impact: piRNAs could serve as promising noninvasive biomarkers for early detection of colon cancer. Cancer Epidemiol Biomarkers Prev; 27(9); 1019–28. ©2018 AACR.
Synaptopathy in the Aging Cochlea: Characterizing Early-Neural Deficits in Auditory Temporal Envelope Processing

Aging listeners, even in the absence of overt hearing loss measured as changes in hearing thresholds, often experience impairments processing temporally complex sounds such as speech in noise. Recent evidence has shown that normal aging is accompanied by a progressive loss of synapses between inner hair cells and auditory nerve fibers. The role of this cochlear synaptopathy in degraded temporal processing with age is not yet understood. Here, we used population envelope following responses, along with other hair cell- and neural-based measures from an age-graded series of male and female CBA/CaJ mice to study changes in encoding stimulus envelopes. By comparing responses obtained before and after the application of the neurotoxin ouabain to the inner ear, we demonstrate that we can study changes in temporal processing on either side of the cochlear synapse. Results show that deficits in neural coding with age emerge at the earliest neural stages of auditory processing and are correlated with the degree of cochlear synaptopathy. These changes are seen before losses in neural thresholds and particularly affect the suprathreshold processing of sound. Responses obtained from more central sources show smaller differences with age, suggesting compensatory gain. These results show that progressive cochlear synaptopathy is accompanied by deficits in temporal coding at the earliest neural generators and contribute to the suprathreshold sound processing deficits observed with age. SIGNIFICANCE STATEMENT Aging listeners often experience difficulty hearing and understanding speech in noisy conditions. The results described here suggest that age-related loss of cochlear synapses may be a significant contributor to those performance declines. We observed aberrant neural coding of sounds in the early auditory pathway, which was accompanied by and correlated with an age-progressive loss of synapses between the inner hair cells and the auditory nerve. Deficits first appeared before changes in hearing thresholds and were largest at higher sound levels relevant to real world communication. The noninvasive tests described here may be adapted to detect cochlear synaptopathy in the clinical setting.
The long-term prognostic significance of high-sensitive C-reactive protein to in-stent restenosis

Background: In the current meta-analysis, we aim to assess the effect of high-sensitive C-reactive protein (hs-CRP) on in-stent restenosis (ISR) outcome in patients receiving stent implantation. Methods: Embase, PubMed, and Cochrane databases were searched through October 2016 using the keywords “high-sensitive C-reactive protein,” “in-stent restenosis. ” An odds ratio (OR) of on ISR endpoints among patients receiving stent implantation was calculated using random-effects models. Results: In the meta-analysis of 6 prospective observational studies, there are 1156 coronary heart disease (CHD) patients, a total of 885 stents were implanted and 194 ISR events had been followed up for 6 to 12 months; high-sensitive C-reactive protein levels are associated with the prediction of in-stent restenosis among patients receiving stent implantation. The OR of hs-CRP for ISR was 1.16 [95% confidence interval (CI), 1.01–1.30, P < . 05]. Conclusions: This meta-analysis shows that higher levels of hs-CRP are associated with an increased risk of ISR and indicate a poorer prognosis in CHD patients after stent implantation.
The clinical outcomes and surgical strategy for cervical spine tuberculosis

Abstract Literature on the treatment of cervical spinal tuberculosis (CSTB) is uncommon, the surgical approaches to cervical spinal tuberculosis were controversial. The aim of the study was to evaluate the clinical outcomes of 3 surgical techniques in CSTB patients, and to determine the most appropriate approach for CSTB patients. Between April 2006 and June 2012, we performed a retrospective review of clinical and radiographic data that were collected from 850 consecutive spinal tubercular patients, including 87 patients who were diagnosed and treated for CSTB in our hospital. Apart from 9 patients being treated conservatively, the remainder (78 cases) underwent surgery by anterior debridement, interbody fusion and instrumentation (A group), posterior instrumentation and anterior debridement, fusion and instrumentation in a single or two-stage operation (AP group), or posterior debridement, fusion and posterior instrumentation (P group). The patients were evaluated preoperatively and postoperatively on the basis of hematologic, radiographic examinations, and neurologic function. The 78 patients were followed up for a mean duration of 41.2 ± 7.2 months (range, 24–65 months). Postoperatively, the preoperative erythrocyte sedimentation rate (ESR) value returned to normal within 3 to 6 months in all patients, and solid bone fusion was achieved in 3 to 8 months. The patients exhibited significant improvement in deformity and neurological deficit postoperatively, while the visual analog scale for pain showed significant improvement in all patients at the last follow up visit. The follow-up outcomes demonstrated that all 3 surgical methods were viable management options for CSTB. Individualized therapeutic strategies should be selected according to the patient's general condition, focal characteristics, and the surgeon's experience.
Dog Ecology and Rabies Knowledge of Owners and Non-Owners in Sanur, A Sub-District of the Indonesian Island Province of Bali

Simple Summary That rabies can be managed humanely using vaccination is well accepted. However, making sure enough dogs in the population are vaccinated and therefore able to fight off the virus can be challenging. Getting owners to be more responsible for their dogs should help keep the proportion of vaccinated dogs high. This study looked at dogs and people living in three villages in Sanur, Bali; the total population of dogs was 6009, of which only 200 dogs appeared to have no owner. There were some differences between these 6009 dogs in terms of their welfare, the likelihood of them being unvaccinated, the method owners used to confine them, whether they were sterilised, and where owners got them from. Most people were well informed about rabies and had positive attitudes towards dogs and vaccination. This information could then be used to plan a project to improve responsible dog ownership. Abstract This study gained an understanding of dog demographics, owner behaviour, and knowledge, attitudes and practices relating to rabies in three villages in Sanur, Bali, providing insights for an intervention to improve responsible dog ownership. A combination of a census of all dogs, street surveys of roaming dogs, and a Knowledge, Attitude and Practices (KAP) survey was used to study both dogs and people. A total of 6009 dogs were recorded, of which only 3.3% appeared to be unowned; unowned dogs had poorer welfare and were more likely to be wary of attempted approaches by people. The source of dogs, method of confinement used by owners, and whether dogs were sterilised differed between three breed types; purebred dogs, mixed breed, and Bali dogs (native breed). Three variables were found to have significant effects on the chances of not being vaccinated: age, dog type, and confinement. A mean of 3.81 roaming dogs per km of street surveyed was recorded along 28 sub-village routes. Responses to attitude statements showed that most people had a positive attitude towards dogs and vaccination and did not agree with culling. Knowledge of appropriate bite treatment and symptoms of rabies in dogs was good.
Association of infant formula composition and anthropometry at 4 years: Follow-up of a randomized controlled trial (BeMIM study)

The relationships between nutrition, metabolic response, early growth and later body weight have been investigated in human studies. The aim of this follow-up study was to assess the long-term effect of infant feeding on growth and to study whether the infant metabolome at the age of 4 months might predict anthropometry at 4 years of age. The Belgrade-Munich infant milk trial (BeMIM) was a randomized controlled trial in which healthy term infants received either a protein-reduced infant formula (1.89 g protein/100 kcal) containing alpha-lactalbumin enriched whey and long-chain polyunsaturated fatty acids (LC-PUFA), or a standard formula (2.2 g protein/100 kcal) without LC-PUFA, focusing on safety and suitability. Non-randomized breastfed infants were used as a reference group. Of the 259 infants that completed the BeMIM study at the age of 4 months (anthropometry assessment and blood sampling), 187 children participated in a follow-up visit at 4 years of age. Anthropometry including weight, standing height, head circumference, and percent body fat was determined using skinfolds (triceps, subscapular) and bioelectrical impedance analysis. Plasma metabolite concentration, collected in samples at the age of 4 months, was measured using flow-injection tandem mass spectrometry. A linear regression model was applied to estimate the associations between each metabolite and growth with metabolites as an independent variable. At 4 years of age, there were no significant group differences in anthropometry and body composition between formula groups. Six metabolites (Asn, Lys, Met, Phe, Trp, Tyr) measured at 4 months of age were significantly associated with changes in weight-for-age z-score between 1 to 4 months of age and BMI-for-age z-score (Tyr only), after adjustment for feeding group. No correlation was found between measured metabolites and long-term growth (up to 4 years of age). No long-term effects of early growth patterns were shown on anthropometry at 4 years of age. The composition of infant formula influences the metabolic profile and early growth, while long-term programming effects were not observed in this study.
Time, memory, and the legacy of Howard Eichenbaum

Over the past 15 years, there has been an explosion of new research on the role of the hippocampus in the representation of information about time in memory. Much of this work was inspired by the ideas and research of Howard Eichenbaum, who made major contributions to our understanding of the neurobiology of episodic memory and the neural representation of time. In this article, I will review evidence regarding the role of time in understanding hippocampal function. This review will cover a broad range of evidence from studies of humans and nonhuman animals with a narrative arc that follows Howard's major discoveries. These studies demonstrate that the hippocampus encodes information in relation to an episodic context, and that time, as well as space, serves to define these contexts. Moreover, the research has shown that the hippocampus can encode temporal, spatial, and situational information in parallel. Building on this work, I present a new framework for understanding temporal structure in human episodic memory. I conclude by outlining current controversies and new questions that must be addressed by the field in the years to come.
