Abstract
INTRODUCTION Flexible nasendoscopy (FNE) is the principal assessment method for vocal cord movement. Because the procedure is inherently subjective it may not be possible for clinicians to grade the degree of vocal cord movement reliably. The aim of this study was to assess the accuracy and consistency of grading vocal cord movement as viewed via FNE. METHODS Thirty FNE videos, without sound or clinical information, were assessed by six consultant head and neck surgeons. The surgeons were asked to assess and grade right and left vocal cord movement independently, based on a five-category scale. This process was repeated three times on separate occasions. Agreement and reliability were assessed. RESULTS Mean overall observed inter-rater agreement was 67.7% (sd 1.9) with the five-category scale, increasing to 91.4% (sd 1.9) when a three-category scale was derived. Mean overall observed intra-rater agreement was 78.3% (sd 9.7) for five categories, increasing to 93.1% (sd 3.3) for three categories. Discriminating vocal cord motion was less reliable using the five-category scale (k = 0.52) than with the three-category scale (k = 0.68). CONCLUSIONS This study demonstrates quantitatively that it is challenging to accurately and consistently grade subtle differences in vocal cord movement, as proven by the reduced agreement and reliability when using a five-point scale instead of a three-point scale. The study highlights the need for an objective measure to help in the assessment of vocal cord movement.

Abstract
BACKGROUND Persons with Multiple Sclerosis (PwMS) have a higher rate of anxiety and depression than the general population. Depression has been associated with clinical relapses; temporal lesions were shown to predict depression severity. Anxiety is considerably understudied. The role of MS lesions in the limbic system is also understudied, partly due to difficulties identifying limbic lesions on standard 1.5 and 3 Tesla MRI. METHODS This is a retrospective study of 23 PwMS who underwent 7T MRI on the same day as completing the Hospital Anxiety and Depression Scale (HADS). MRI was performed on a Siemens 7T MRI Plus and an 8-channel transmit coil with 32 receiver channels operating in pTx mode. MP2RAGE and DIR-SPACE sequences were analyzed to determine the number of lesions within the limbic system. RESULTS The median number of lesions in the limbic system was 2.0 (range 0-7). When comparing the presence or absence of lesions in the limbic system, there was a significant relationship with anxiety (X2 (1, N = 23)=4.44, p = 0.035), but not for depression. CONCLUSION Although only a small sample size, this study provides preliminary evidence that lesions in the limbic system are associated with the presence of anxiety in PwMS. This relationship warrants further investigation.

Abstract
The sarcoglycanopathies are autosomal recessive limb-girdle muscular dystrophies (LGMDs) caused by the mutations in genes encoding the α, β, γ, and δ proteins which stabilizes the sarcolemma of muscle cells. The clinical phenotype is characterized by progressive proximal muscle weakness with childhood onset. Muscle biopsy findings are diagnostic in confirming dystrophic changes and deficiency of one or more sarcoglycan proteins. In this study, we summarized 1,046 LGMD patients for which a precise diagnosis was identified using targeted sequencing. The most frequent phenotypes identified in the patients are LGMDR1 (19.7%), LGMDR4 (19.0%), LGMDR2 (17.5%), and MMD1 (14.5%). Among the reported genes, each of CAPN3, SGCB, and DYSF variants was reported in more than 10% of our study cohort. The most common variant SGCB p.Thr182Pro was identified in 146 (12.5%) of the LGMD patients, and in 97.9% of these patients, the variant was found to be homozygous. To understand the genetic structure of the patients carrying SGCB p.Thr182Pro, we genotyped 68 LGMD patients using a whole genome microarray. Analysis of the array data identified a large ~1 Mb region of homozygosity (ROH) (chr4:51817441-528499552) suggestive of a shared genomic region overlapping the recurrent missense variant and shared across all 68 patients. Haplotype analysis identified 133 marker haplotypes that were present in ~85.3% of the probands as a double allele and absent in all random controls. We also identified 5 markers (rs1910739, rs6852236, rs13122418, rs13353646, and rs6554360) which were present in a significantly higher proportion in the patients compared to random control set (
) and the population database. Of note, admixture analysis was suggestive of greater proportion of West Eurasian/European ancestry as compared to random controls. Haplotype analysis and frequency in the population database indicate a probable event of founder effect. Further systematic study is needed to identify the communities and regions where the SGCB p.Thr182Pro variant is observed in higher proportions. After identifying these communities and//or region, a screening program is needed to identify carriers and provide them counselling.

Abstract
This paper observes the increasing influence of godmen in India and the socio-economic division among devotees that influences their decision to follow them. The study navigates through various social spheres and predominantly focuses on lower-income groups, middle-income groups, and upper-income groups to piece together the research paper. It focuses on in-depth interviews as a primary source of understanding these differences and is followed by possible deductions of the same, keeping in mind the hypothesis that there is a socio-economic divide in this seemingly secular framework of spirituality and religion, as defined by the devotees. These interviews are narrative analyzed to detect any recurring patterns within the economic groups and the following groups. Constructivism as a theory is used to understand how the arguments put forward by the interviewees are influenced by their social position in society and how they are inclined towards understanding reality on individual terms. The study’s findings prove that a possible correlation can be derived between an individual’s economic standing and expectations while following a certain godmen.

Abstract
A comparative study of existing junction-primer-designing software revealed many limitations among them. Hence, we developed a new computational program, Ex-Ex Primer, which offers many improved, user-friendly features, and reliably creates junction primers and probes. This online suite can also be used to design primers/probes from other sites of nucleic acid recombination, insertion, deletion, or splicing, and regular probes/primers. The threshold for Tm difference between the complete junctional primer vs its partial sequence, which maps to one of the junctional regions, was changed based on an important observation made during the initial experimental validations. The tool is now thoroughly checked with RT-PCR and RT-qPCR experiments with more than 250 primer pairs over a few years. The junction-primer-designing features of the software are also better than other equivalent tools. Visualizing the exons and introns across transcripts, and enabling primer designing based on information from Ensembl, are some of the unique features of this tool. The primers suggested by the tool can be used to detect the expression of known transcripts, to test the existence of predicted DNA or RNA joints via hybridization-based techniques, or for validation and in silico analysis of RNA-Seq.

Abstract
Abstract
Objectives
Health outcomes in previous fiber intervention studies have been variable, potentially due to differences in gut microbiome composition. This study aimed to determine if the effect of fiber intervention on the microbiome differs by initial microbiome or the quantity of fiber provided.
Methods
This study was designed as a randomized, un-blinded, cross-over trial of fiber cereal dosage. The cross-over design tested the effect of two 2-week long interventions with a High (28g) and Low (14g) level of daily supplemental fiber from whole wheat and bran cereal. Analysis was also completed on the overall study as a single arm, non-randomized, intervention of fiber cereal. The study enrolled 31 healthy adults. The microbiome was assessed at baseline and after intervention for changes in diversity, composition, and stability.
Results
Across all individuals, fiber intervention increased microbiome alpha-diversity (paired t-test, P = 0.047), but the microbiome was otherwise resistant to the effects of the intervention. Increasing fiber dose (High v. Low) was not associated with consistent changes in beta-diversity (linear mixed models). Approximately 20% of subjects were identified as responders based on beta diversity effect size. At baseline, responders had higher Prevotella copri and lower Bacteroides abundance than non-responders (Wilcoxon rank sum, qval < 0.05). In responders, fiber intake caused increased abundance of Bacteroides and Alistipes and reduced Prevotella (paired Wilcoxon, q < 0.2). In all subjects, fiber intervention decreased microbiome stability (paired Wilcoxon signed rank test, P = 0.006). In responders, there was a significant effect of the fiber level on stability, with higher fiber further lowering stability (linear mixed model, P = 0.05).
Conclusions
Our data suggest a responder/non-responder microbiome signature for this whole wheat and bran fiber cereal. We find that many effects were not additive by dosage level. Overall, microbiome diversity was increased and stability was decreased during the fiber cereal intervention and in responders this was dose dependent; the clinical implications of the impact of changes in stability remain unknown, and it is possible that the microbiome would stabilize in a longer intervention study.

Abstract
We have previously reported long-term changes in the brains of non-concussed varsity rugby players using magnetic resonance spectroscopy (MRS), diffusion tensor imaging (DTI) and functional magnetic imaging (fMRI). Others have reported cognitive deficits in contact sport athletes that have not met the diagnostic criteria for concussion. These results suggest that repetitive mild traumatic brain injuries (rmTBIs) that are not severe enough to meet the diagnostic threshold for concussion, produce long-term consequences. We sought to characterize the neuroimaging, cognitive, pathological and metabolomic changes in a mouse model of rmTBI. Using a closed-skull model of mTBI that when scaled to human leads to rotational and linear accelerations far below what has been reported for sports concussion athletes, we found that 5 daily mTBIs triggered two temporally distinct types of pathological changes. First, during the first days and weeks after injury, the rmTBI produced diffuse axonal injury, a transient inflammatory response and changes in diffusion tensor imaging (DTI) that resolved with time. Second, the rmTBI led to pathological changes that were evident months after the injury including: changes in magnetic resonance spectroscopy (MRS), altered levels of synaptic proteins, behavioural deficits in attention and spatial memory, accumulations of pathologically phosphorylated tau, altered blood metabolomic profiles and white matter ultrastructural abnormalities. These results indicate that exceedingly mild rmTBI, in mice, triggers processes with pathological consequences observable months after the initial injury.

Abstract
The developmental trajectory of the primate brain varies substantially with aging across subjects. However, this ubiquitous variability between individuals in brain structure is difficult to quantify and has thus essentially been ignored. Based on a large-scale structural magnetic resonance imaging dataset acquired from 162 cynomolgus macaques, we create a species-specific 3D template atlas of the macaque brain, and deploy normative modeling to characterize individual variations of cortical thickness (CT) and regional gray matter volume (GMV). We observed an overall decrease in total GMV and mean CT, and an increase in white matter volume from juvenile to early adult. Specifically, CT and regional GMV were greater in prefrontal and temporal cortices relative to early unimodal areas. Age-dependent trajectories of thickness and volume for each cortical region revealed an increase in the medial temporal lobe, and decreases in all other regions. A low percentage of highly individualized deviations of CT and GMV were identified (0.0021%, 0.0043%, respectively, P < 0.05, false discovery rate [FDR]-corrected). Our approach provides a natural framework to parse individual neuroanatomical differences for use as a reference standard in macaque brain research, potentially enabling inferences regarding the degree to which behavioral or symptomatic variables map onto brain structure in future disease studies.

Abstract
BACKGROUND The low intake of dietary fiber compared to recommended amounts has been referred to as the dietary fiber gap. The addition of fiber to snack foods could favorably alter gut microbiota and help individuals meet intake recommendations. OBJECTIVES Our objective was to examine the effect of low- and moderate-dose fiber-containing snack bars, comprising mainly chicory root inulin-type fructans (ITF), on gut microbiota in healthy adults with habitual low dietary fiber intake using 16S ribosomal RNA-based approaches. METHODS In 2 separate 4-wk, placebo-controlled, double-blind, crossover trials, 50 healthy adults with low dietary fiber intake were randomly assigned to receive isocaloric snack bars of either moderate-dose fiber (7 g/d) or control in Trial 1 (n = 25) or low-dose fiber (3 g/d) or control in Trial 2 (n = 25), with 4-wk washout periods. Fecal microbiota composition and inferred function, fecal SCFA concentration, gastrointestinal (GI) symptoms, dietary intake, and quality of life were measured. RESULTS Compared with the control group, the moderate-dose group showed significant differences across multiple microbial taxa, most notably an increased relative abundance of the Bifidobacterium genus from (mean ± SEM) 5.3% ± 5.9% to 18.7% ± 15.0%. With low-dose ITF, significant increases in Bifidobacterium were no longer present after correction for multiple comparisons but targeted analysis with qPCR showed a significant increase in Bifidobacterium. Predictive functional profiling identified changes in predicted function after intake of the moderate- but not the low-dose bar. Fecal SCFAs were affected by time but not treatment. There were no between-group differences in GI symptoms. Importantly, fiber intake increased significantly with the moderate- and low-dose bars. CONCLUSIONS In healthy adults, adding 3 or 7 g ITF to snack bars increased Bifidobacterium, a beneficial member of the gut microbial community. The addition of ITF to food products could help reduce the dietary fiber gap prevalent in modern life.This trial was registered at clinicaltrials.gov as NCT03042494.

Abstract
INTRODUCTION Globally, preterm birth has replaced congenital malformation as the major cause of perinatal mortality and morbidity. The reduced rate of congenital malformation was not achieved through a single biophysical or biochemical marker at a specific gestational age, but rather through a combination of clinical, biophysical and biochemical markers at different gestational ages. Since the aetiology of spontaneous preterm birth is also multifactorial, it is unlikely that a single biomarker test, at a specific gestational age will emerge as the definitive predictive test. METHODS The Biomarkers Group of PREBIC, comprising clinicians, basic scientists and other experts in the field, with a particular interest in preterm birth have produced this commentary with short, medium and long-term aims: i) to alert clinicians to the advances that are being made in the prediction of spontaneous preterm birth; ii) to encourage clinicians and scientists to continue their efforts in this field, and not to be disheartened or nihilistic because of a perceived lack of progress and iii) to enable development of novel interventions that can reduce the mortality and morbidity associated with preterm birth. RESULTS Using language that we hope is clear to practising clinicians, we have identified 11 Sections in which there exists the potential, feasibility and capability of technologies for candidate biomarkers in the prediction of spontaneous preterm birth and how current limitations to this research might be circumvented. DISCUSSION The combination of biophysical, biochemical, immunological, microbiological, fetal cell, exosomal, or cell free RNA at different gestational ages, integrated as part of a multivariable predictor model may be necessary to advance our attempts to predict sPTL and PTB. This will require systems biological data using "omics" data and artificial intelligence/machine learning to manage the data appropriately. The ultimate goal is to reduce the mortality and morbidity associated with preterm birth.

Abstract
Introduction Endoscopic strip craniectomy with helmeting (ESCH) has been shown to be a safe and efficacious alternative to fronto-orbital remodeling (FOR) for selected children with craniosynostosis. In addition to clinical factors, there may be economic benefits from the use of ESCH instead of FOR. Methods A retrospective review of 23 patients with nonsyndromic unicoronal craniosynostosis (UCS) treated with FOR was carried out at Great Ormond Street Hospital (GOSH) for Children in London, UK. Secondary data were used for the ESCH cohort from a paper published by Jimenez and Barone (2013). Data were collected on surgical time, transfusion rates, length of hospital stay, adverse event rates, reintervention rates, and overall costs. Costs were categorized and then assigned to the appropriate data sets. Results The mean age of patients undergoing FOR (vs. ESCH) was 17.4 mo (vs. 3.1 mo) with a mean surgical time of 234 min (vs. 55 min), mean transfusion volume of 221.6 mL (vs. 80.0 mL), mean transfusion rate of 14/23 (vs. 2/115), and a total immediate overnight stay of 3.13 days (vs. 97% next-day discharge). The FOR group had a higher adverse event rate (5/23 vs. 4/115, p=<0.005) and a higher number requiring extraocular muscle surgery (4/23 vs. 7/109, p=0.16). There was a substantial difference in overall costs between the two groups. Total variance cost for the FOR group was £7436.5 vs. £4951.35, representing a cost difference of £2485.15 over the 24-month study period. Conclusion ESCH, in comparison to FOR, appears as a more economical method in the management of USC patients, as well as having clinical benefits including reduced adverse event rate and improved ophthalmic outcomes.

Abstract
Diet is a key determinant of human gut microbiome variation. However, the fine-scale relationships between daily food choices and human gut microbiome composition remain unexplored. Here, we used multivariate methods to integrate 24-h food records and fecal shotgun metagenomes from 34 healthy human subjects collected daily over 17 days. Microbiome composition depended on multiple days of dietary history and was more strongly associated with food choices than with conventional nutrient profiles, and daily microbial responses to diet were highly personalized. Data from two subjects consuming only meal replacement beverages suggest that a monotonous diet does not induce microbiome stability in humans, and instead, overall dietary diversity associates with microbiome stability. Our work provides key methodological insights for future diet-microbiome studies and suggests that food-based interventions seeking to modulate the gut microbiota may need to be tailored to the individual microbiome.

Abstract
AIMS The concept of using specific dietary components to selectively modulate the gut microbiota to confer a health benefit, defined as prebiotics, originated in 1995. In 2018, a group of scientists met at the International Scientific Association for Probiotics and Prebiotics annual meeting in Singapore to discuss advances in the prebiotic field, focussing on issues affecting functionality, research methodology and geographical differences. METHODS AND RESULTS The discussion ranged from examining scientific literature supporting the efficacy of established prebiotics, to the prospects for establishing health benefits associated with novel compounds, isolated from different sources. CONCLUSIONS While many promising candidate prebiotics from across the globe have been highlighted in preliminary research, there are a limited number with both demonstrated mechanism of action and defined health benefits as required to meet the prebiotic definition. Prebiotics are part of a food industry with increasing market sales, yet there are great disparities in regulations in different countries. Identification and commercialization of new prebiotics with unique health benefits means that regulation must improve and remain up-to-date so as not to risk stifling research with potential health benefits for humans and other animals. SIGNIFICANCE AND IMPACT OF STUDY This summary of the workshop discussions indicates potential avenues for expanding the range of prebiotic substrates, delivery methods to enhance health benefits for the end consumer and guidance to better elucidate their activities in human studies.

Abstract
Adolescence is a critical period characterized by physical, social, and developmental changes that impact on health and eating behaviour. Indonesia is experiencing dramatic economic and infrastructural changes, causing greater access to the global food industry and media. This transition is influencing food intake trends, leading to new nutritional challenges in adolescent girls. Qualitative research was conducted between November 2016 and January 2017 in five urban sites in Java, Indonesia, to examine individual, social, environmental, and macrosystem factors affecting snacking behaviours in unmarried adolescent girls 16–19 years of age. Methods entailed 30 freelisting exercises, nine key informant interviews, and 16 in‐depth interviews. Freelisting results identified over 200 snack foods, with the most salient processed convenience foods such as chips and cookies. Respondents typically snacked multiple times daily. Widespread availability of affordable and “tasty” snacks makes snack foods appealing meal substitutes. Snacks provide a distraction to boredom and loneliness and an enhancement to social gatherings. Girls exhibited limited understanding or concern about potential negative effects of snacking. Parents facilitate acquisition of nutrient‐poor snacks, whereas friends exert pressure for routine consumption of snack foods. Social media infiltrated with promotions of eateries and snack foods is likely contributing to the preponderance of snack food consumption. Routine consumption of snack foods high in sugar, salt, and fat and skipping meals will likely have long‐term consequences on the nutritional status and health of Indonesian adolescent girls. Findings underline the urgent need to develop contextually relevant, targeted behavioural change strategies to modify the potentially harmful eating and activity patterns of adolescent girls identified in this study and to curb the trajectory of overweight in urban Indonesia.

Abstract
Takotsubo (stress) cardiomyopathy, is defined by transient left ventricular systolic dysfunction without epicardial coronary disease. Case report A 50-year-old man presented with headache and visual disturbance with no past medical history of note. He had recently separated from his wife and children had moved out of the family home. He was very depressed and stressed due to this. His blood pressure was 180/110 mmHg and bloods showed creatinine of 442 umol/L; potassium 3.6 mmol/L; eGFR 13 mL/min/1.73m2. Renal Ultrasound and virology/immunology screen were normal. Echocardiogram showed severe left ventricular (LV) dysfunction with an ejection fraction (EF) of 35% with LV hypertrophy. Plasma normetanephrine and metanephrine levels were elevated at 4805 pmol/L (120-1180) and 819 (80 - 510) respectively. Urine 24 hour metanephrines showed elevated urine normetanephrine output of 7.62 umol/24 h (0-3.3) and mildly elevated urine metanephrine output of 1.31 umol/24 h (0-1.2). CT Adrenals showed a low density 1 cm left adenoma with benign washout characteristics. He was started on alphablocker and amlodipine with good effect. 2 months later, repeat Echo normalised with LVEF of 55-60%. Repeat urine metanephrines were normal. Plasma normetanephrine dropped to 1253 pmol/L and plasma metanephrine to 338 pmol/L. I123 MIBG (meta-iodo-benzyl guanidine) SPECT-CT normal uptake. Overnight dexamethasone suppression test and aldosterone renin ratio were normal. Discussion: This 50-year-old gentleman under considerable emotional stress, presented with severe hypertension and severely impaired LV function. On follow-up, the LV impairment returned to normal and the initially elevated plasma and urine metanephrines normalised. The adrenal tumour was an incidental benign non-secretory tumour. There are several reports of phaeochromocytomas presenting with stress cardiomyopathy, however stress cardiomyopathy mimicking phaeochromocytoma is not well reported. A study by Wittstein et al reported significant elevations of metanephrines in patients with stress cardiomyopathy. However this has not been universally accepted and subsequent studies have not fully replicated this. As per a 2017 metanalysis by Darr et al the sensitivity and specificity of plasma metanephrines for phaeochromocytoma/paraganglioma is 94% and 93% and for urinary metanephrines, 91% and 93%. Critical illness can elevate plasma and urinary metanephrines. In this case, the patient did have severe hypertension, but was not critically ill. The current case report provides a cautionary example that the specificity of plasma and urinary metanephrines in the diagnosis of phaeochromocytoma and paraganglioma may be impaired in people presenting with stress related cardiomyopathy. This is especially true in this case given that this patient also had an incidental adrenal tumour.

Abstract
BACKGROUND There are complex interactions between aging, frailty, diet, and the gut microbiota; modulation of the gut microbiota by diet could lead to healthier aging. The purpose of this study was to test the effect of diets differing in sugar, fat, and fiber content upon the gut microbiota of mice humanized with microbiota from healthy or frail older people. We also performed a 6-month dietary fiber supplementation in three human cohorts representing three distinct life-stages. METHODS Mice were colonized with human microbiota and then underwent an 8-week dietary intervention with either a high-fiber/low-fat diet typical of elderly community dwellers or a low-fiber/high-fat diet typical of long-stay residential care subjects. A cross-over design was used where the diets were switched after 4 weeks to the other diet type to identify responsive taxa and innate immunity changes. In the human intervention, the subjects supplemented their normal diet with a mix of five prebiotics (wheat dextrin, resistant starch, polydextrose, soluble corn fiber, and galactooligo-saccharide) at 10 g/day combined total, for healthy subjects and 20 g/day for frail subjects, or placebo (10 g/day maltodextrin) for 26 weeks. The gut microbiota was profiled and immune responses were assayed by T cell markers in mice, and serum cytokines in humans. RESULTS Humanized mice maintained gut microbiota types reflecting the respective healthy or frail human donor. Changes in abundance of specific taxa occurred with the diet switch. In mice with the community type microbiota, the observed differences reflected compositions previously associated with higher frailty. The dominance of Prevotella present initially in community inoculated mice was replaced by Bacteroides, Alistipes, and Oscillibacter. Frail type microbiota showed a differential effect on innate immune markers in both conventional and germ-free mice, but a moderate number of taxonomic changes occurring upon diet switch with an increase in abundance of Parabacteroides, Blautia, Clostridium cluster IV, and Phascolarctobacterium. In the human intervention, prebiotic supplementation did not drive any global changes in alpha- or beta-diversity, but the abundance of certain bacterial taxa, particularly Ruminococcaceae (Clostridium cluster IV), Parabacteroides, Phascolarctobacterium, increased, and levels of the chemokine CXCL11 were significantly lower in the frail elderly group, but increased during the wash-out period. CONCLUSIONS Switching to a nutritionally poorer diet has a profound effect on the microbiota in mouse models, with changes in the gut microbiota from healthy donors reflecting previously observed differences between elderly frail and non-frail individuals. However, the frailty-associated gut microbiota did not reciprocally switch to a younger healthy-subject like state, and supplementation with prebiotics was associated with fewer detected effects in humans than diet adjustment in animal models.

Abstract
The objective of this study was to examine the influence of improved information and educational messages on outer packaging of a micronutrient powder (MNP), locally known as “Taburia”, on knowledge and adherence to recommended use. A community-based cluster randomized controlled trial was conducted among 1149 caregivers and their children aged 6⁻36 months. Caregiver⁻child dyads were randomized by their villages to receive 30 sachets of Taburia with the: (i) original outer packaging; (ii) improved outer packaging; or (iii) improved outer packaging combined with cooking demonstrations. Adherence to Taburia use was assessed through caregiver interviews and observation of unused sachets during home visits; “high” adherence was defined as consuming 13⁻17 sachets in the previous month. Data collection included surveys and focus groups discussions. The majority of caregivers (>80%) preferred the improved packaging because it was more attractive and contained more comprehensive information. Caregivers who received the improved packaging had better knowledge regarding the recommended use of Taburia (p < 0.001) and higher adherence with the prescribed use of Taburia (43% with “high” adherence) (p < 0.001) than those who received the original packaging (29% with “high” adherence). Caregivers who participated in cooking demonstrations generally had better knowledge regarding the benefits of Taburia and recommended use, but this did not lead to higher adherence to recommended use. “Underconsumption” of Taburia (≤7 sachets) was much less prevalent than “overconsumption” (≥23 sachets), and original packaging users were more likely to consume Taburia daily instead of every two days as recommended. We conclude that the design of the outer packaging and comprehensiveness of information provided are important influencers of recommended MNP use by caregivers.

Abstract
Concomitant cerebral infarction developing soon after a parenchymal intracerebral hemorrhage is a rare occurrence. Usually, these remote site changes follow tumor decompression and are associated with hemorrhagic changes rather than infarcts. We report a case of a fatal malignant internal carotid territory infarct in a hospitalized patient being conservatively managed for a vermian hematoma and discuss the probable pathophysiology. Stroke physicians need to be aware that spontaneous intracerebral hematoma patients have a potential threat of developing large vessel occlusion with malignant cerebral infarcts, especially after surgical decompression. Although the exact pathogenesis is unknown, size of the clot, intraventricular hemorrhage, hydrocephalus, and aggressive reduction of blood pressure appear to be predictive factors.

Abstract
Sarcoma-180 tumour (S-180) exhibits natural resistance to bouvardin (NSC 259968), a protein synthesis inhibitor that also inhibits RNA and DNA synthesis when administered over a range of non-toxic doses using 0.9 % NaCl as a vehicle. However, using Tween-80 as a vehicle, there is a substantial enhancement of cytotoxicity and a subsequent increase in the life span of animals bearing the S-180 tumour. This observation was substantiated in vitro by exposing S-180 cells to 10−6 M bouvardin in the presence and absence of Tween-80. Bouvardin, 10−6 M, in the absence of Tween-80, inhibited the incorporation of [3H]uridine by 46 %, whereas the presence of Tween-80 resulted in a 66 % inhibition of uridine incorporation.

Abstract
Bouvardin, a new antineoplastic plant product, inhibits macromolecular synthesis in P388 cells in a dose-dependent manner. At the same concentration of bouvardin, protein synthesis was inhibited to a greater extent than the synthesis of DNA and RNA. There was a reversal of inhibition of both DNA and RNA synthesis after the cells were washed free of bouvardin. However, there was partial reversal of inhibition of protein synthesis when the cells were washed free of the drug.

Abstract
Global recognition that the complex and multicausal problems of malnutrition require all players to collaborate and to invest towards the same objective has led to increased private sector engagement as exemplified through the Scaling Up Nutrition Business Network and mechanisms for blended financing and matched funding, such as the Global Nutrition for Growth Compact. The careful steps made over the past 5 to 10 years have however not taken away or reduced the hesitation and scepticism of the public sector actors towards commercial or even social businesses. Evidence of impact or even a positive contribution of a private sector approach to intermediate nutrition outcomes is still lacking. This commentary aims to discuss the multiple ways in which private sector can leverage its expertise to improve nutrition in general, and complementary feeding in particular. It draws on specific lessons learned in Bangladesh, Côte d'Ivoire, India, Indonesia, and Madagascar on how private sector expertise has contributed, within the boundaries of a regulatory framework, to improve availability, accessibility, affordability, and adequate use of nutritious foods. It concludes that a solid evidence base regarding the contribution of private sector to complementary feeding is still lacking and that the development of a systematic learning agenda is essential to make progress in the area of private sector engagement in nutrition.

Abstract
BACKGROUND The study aims to evaluate the methodological quality of publications relating to predicting the need of conversion from laparoscopic to open cholecystectomy and to describe identified prognostic factors. METHOD Only English full-text articles with their own unique observations from more than 300 patients were included. Only data using multivariate analysis of risk factors were selected. Quality assessment criteria stratifying the risk of bias were constructed and applied. RESULTS The methodological quality of the studies were mostly heterogeneous. Most studies performed well in half of the quality criteria and considered similar risk factors, such as male gender and old age, as significant. Several studies developed prediction models for risk of conversion. Independent risk factors appeared to have additive effects. CONCLUSION A detailed critical review of studies of prediction models and risk stratification for conversion from laparoscopic to open cholecystectomy is presented. One study is identified of high quality with a potential to be used in clinical practice, and external validation of this model is recommended.

Abstract
We report a case of crizotinib effectiveness in a heavily pretreated patient with a metastatic NSCLC initially considered IHC-positive and FISH-negative for ALK rearrangement. After repeated analyses of tumor samples, borderline ALK FISH-positivity (18.5% positive cells) was demonstrated.

Abstract
Oats have a long history of use as human food and animal feed. From its origins in the Fertile Crescent, the oat has adapted to a wide range of climatic conditions and geographic regions. Its unique macro-, micro-, and phytonutrient composition, high nutritional value, and relatively low agricultural input requirements makes oats unique among cereal crops. The health benefits of the oats are becoming well established. While the connection between oat β-glucan fiber in reducing the risk of cardiovascular disease and controlling glycemia have been unequivocally established, other potential benefits including modulation of intestinal microbiota and inflammation continue to be explored. Advances in food technology are continuing to expand the diversity of oat-based foods, creating opportunities to deliver the health benefits of oats to a larger segment of the population.
