Characteristics of unplanned hospitalisations among cancer patients in Singapore

Introduction: Cancer is a pervasive global problem with significant healthcare utilisation and cost. Emergency departments (EDs) see large numbers of patients with oncologic emergencies and act as “gate-keepers” to subsequent hospital admissions. A proportion of such hospital admissions are rapidly discharged within 2 days and may be potentially avoidable. Methods: Over a 6-month period, we conducted a retrospective audit of active cancer patients presenting to the ED with subsequent admission to the Department of Medical Oncology. Our aims were to identify independent factors associated with a length of stay ≤2 days; and characterise the clinical and resource needs of these short admissions. Results: Among all medical oncology admissions, 24.4% were discharged within 2 days. Compared to longer stayers, patients with short admissions were significantly younger (P=0.010), had lower National Early Warning Scores (NEWS) (P=0.006), and had a lower proportion of gastrointestinal and hepatobiliary cancers (P=0.005). Among short admissions, common presenting medical problems were infections (n=144, 36.3%), pain (n=116, 29.2%), gastrointestinal complaints (n=85, 21.4%) and respiratory complaints (n=76, 19.1%). These admissions required investigations and treatments already available at the ED. Conclusion: Short admissions have low resource needs and may be managed in the ED. This may help save valuable inpatient bed-days and reduce overall healthcare costs. Keywords: Emergency medicine, healthcare use, oncology, palliative care, unplanned cancer admission

Association between Dietary Factors and Constipation in Adults Living in Luxembourg and Taking Part in the ORISCAV-LUX 2 Survey

Constipation, a disorder of bowel movements, is among the most frequent gastrointestinal complaints in Western countries. Dietary constituents such as inadequate fiber intake have been related to constipation, but discrepancies exist in the findings regarding dietary factors. This study investigated the association between dietary patterns and bowel movements in adults living in Luxembourg. Data from 1431 participants from ORISCAV-LUX 2 (a cross-sectional survey) who completed a 174-item food frequency questionnaire (FFQ) were analyzed. A questionnaire-based constipation score was assessed by a validated scoring system. Confounders such as physical activity and serum/urine indicators were assessed. Women had higher constipation scores than men (p < 0.001). In food group-based regression models, a negative association was found between higher constipation score and intake of grains (Beta = −0.62, 95%CI: −1.18, −0.05) and lipid-rich foods (Beta = −0.84, 95%CI: −1.55, −0.13), while a positive association was found for sugary products (Beta = 0.54, 95%CI: 0.11, 0.97) (p < 0.05). In a nutrient-based regression model, a positive association was found between constipation score and total energy (Beta = 5.24, 95%CI: 0.37, 10.11) as well as sodium intake (Beta = 2.04, 95%CI: 0.21, 3.87), and a negative one was found for total fats (Beta = −4.17, 95%CI: −7.46, −0.89) and starch (Beta = −2.91, 95%CI: −4.47, −1.36) (p < 0.05). Interestingly, neither fruits and vegetables or dietary fiber were significantly associated with constipation. Thus, grains, lipid-rich foods, total fats and starch were associated with a lower constipation score, while sugary products, sodium, and higher energy intake were correlated with higher constipation.

Helicobacter pylori infection and eradication outcomes among Vietnamese patients in the same households: Findings from a non-randomized study

Objective Familial transmission can possibly influence the infection and treatment of Helicobacter pylori. This study aimed to describe the prevalence of H. pylori infection and outcomes of eradication treatment among Vietnamese patients who live in the same households. Methods We conducted a prospective cohort study of Vietnamese household members with upper gastrointestinal complaints. Participants received esophagogastroduodenoscopy and H. pylori testing. The H. pylori-positive patients were treated and asked to return for follow-up within 4 months. To explore factors associated with H. pylori infection at baseline, we performed multilevel logistic regression to account for the clustering effect of living in the same households. To explore factors associated with eradication failure, we used Poisson regression with robust variance estimation to estimate the risk ratio. Results The prevalence of H. pylori infection was 83.5% and highest among children <12 years old (92.2%) in 1,272 patients from 482 households. There were variations in H. pylori infection across households (intraclass correlation = 0.14, 95% confidence interval (CI) 0.05, 0.33). Children aged <12 years had higher odds of H. pylori infection (odds ratio = 3.41, 95%CI 2.11, 5.50). At follow-up, H. pylori was eradicated in 264 of 341 patients (77.4%). The risk of eradication failure was lower for the sequential regimen with tetracycline. Conclusion H. pylori infection was common among people living in the same households. Eradication success for H. pylori was higher for the tetracycline sequential regimen. More research should be focused on how family factors influence H. pylori infection and on eradication treatment.

KBG Syndrome: Prospective Videoconferencing and Use of AI-driven Facial Phenotyping in 25 New Patients

Genetic variants in the gene Ankyrin Repeat Domain 11 (ANKRD11) and deletions in 16q24.3 are known to cause KBG syndrome, a rare syndrome associated with craniofacial, intellectual, and neurobehavioral anomalies. We report 25 unpublished individuals from 22 families, all with molecularly confirmed diagnoses of KBG syndrome. Twenty-one individuals have de novo variants, three have inherited variants, and one is inherited from a mother exhibiting low-level mosaicism. Of these variants, 20 are truncating (frameshift or nonsense), and five are missense. We created a novel protocol for collection and reporting of data, including prospectively interviewing these individuals and their families throughout eight countries via videoconferencing by a single clinician. Participants' medical records, including imaging, were reviewed, and data was uploaded to the Human Disease Gene website using Human Phenotype Ontology (HPO) terms. Photos of the participants were submitted to GestaltMatcher and Face2Gene (FDNA Inc, USA) for facial analysis, and we found similar facial phenotypes among the participants. Within our cohort, common traits included short stature, macrodontia, anteverted nares, wide nasal bridge, wide nasal base, thick eyebrows, synophrys and hypertelorism. Seventy-two percent of participants had gastrointestinal complaints and 80% had hearing loss. Three participants were started on growth hormone with positive results. Behavioral issues and global developmental delays were found in most participants. Neurologic abnormalities including seizures and/or EEG abnormalities were also very common (44%), suggesting that early detection and seizure prophylaxis could be an important point of intervention. Twenty-four percent were diagnosed with attention deficit hyperactivity disorder (ADHD) and 28% were diagnosed with autism spectrum disorder (ASD). Additionally, we have identified minimally reported symptoms, including recurrent sinus infections (16%) and previously unreported migraines (20%). Based on the videoconferencing and these data, we provide a set of recommendations regarding diagnostic and treatment approaches for KBG syndrome.

Ambuláns rehabilitációs programok COVID–19-betegek számára

Összefoglaló. A COVID–19-fertőzésen átesett betegek közül többen elhúzódó panaszokról számolnak be a felépülést követően, sokaknál tartósan fennáll a köhögés, a nehézlégzés, a mellkasi fájdalom, a légszomj attól függetlenül, hogy enyhe vagy súlyosabb tüneteket okozott a koronavírus. A betegek erőtlennek érzik magukat, erős fáradtságérzetre panaszkodnak, míg mások gyomor-bél rendszeri panaszokra, fejfájásra, depresszióra, a szaglás- és ízérzékelés elvesztésére. Számtalan kutatás leírja, hogy a fertőzés még akár hónapokkal később is hatással lehet a tüdő működésére, és korábban egészséges tüdőn is látható a koronavírus-fertőzés a gyógyulás után három hónappal készült kontroll-mellkas-CT-leleten. Éppen ezért szükség van a fertőzés lezajlását követően tüdőgyógyászati kivizsgálásra, ha a betegnek elhúzódó panaszai vannak, vagy ha a betegség tüdőgyulladást okozott. Szükség van a jelenleg működő fekvőbeteg-légzőszervi rehabilitáció mellett a kezelés ambuláns kiterjesztésére is, melynek célja újabb kórházi ápolás nélkül a teljes gyógyulás elérése a betegeknél. A COVID–19-fertőzésen átesett betegeknél a komplex rehabilitáció hatására javul a terhelhetőség, az életminőség, javulnak a légzésfunkciós értékek, csökkennek a panaszok, javul a betegek fizikai és pszichikai állapota. Összefoglaló kutatásunk célja áttekinteni, hogy milyen COVID–19 ambuláns rehabilitációs programok indultak el a koronavírus-fertőzésen átesett betegek esetében nemzetközi és hazai színtereken. Orv Hetil. 22021; 162(42): 1671–1677. Summary. Several patients with COVID-19 infection report prolonged complaints after recovery and many of them suffer from persistent cough, dyspnea, chest pain and shortness of breath regardless of whether the coronavirus caused mild or more severe symptoms. They complain of severe fatigue and weakness while others grizzle about gastrointestinal complaints, headache, depression, loss of sense of smell and taste. Numerous studies describe that the infection can affect lung function even in months and coronavirus infection can be detectable in previously healthy lungs by taking a control chest CT scan three months after recovery. Therefore, chest follow-up is required after the infection if the patient has prolonged complaints or if the disease has caused pneumonia. In addition to the currently operating inpatient respiratory rehabilitation, there is also a need for an outpatient extension of treatment to achieve complete recovery in patients without further hospitalization. For those patients who have had the COVID-19 infection complex rehabilitation can improve their workload, quality of life, improves their respiratory function values, reduces their complaints and also improves their physical and mental condition. The aim of our summary research is to review what COVID-19 outpatient rehabilitation programs have been initiated for patients who went through coronavirus infection on international and domestic scenes.

CHD8-associated gastrointestinal complaints are caused by impaired vagal neural crest development and homeostatic imbalance

SummaryGastrointestinal complaints in autism are common and impact the quality of life of affected individuals, yet the underlying mechanisms are understudied. We have found that individuals with mutations in CHD8 present with gastrointestinal disturbances. We have shown that loss of chd8, the sole ortholog of CHD8 in zebrafish, leads to reduced number of enteric neurons and decreased intestinal mobility. However, it remains unclear how chd8 acts during the development of the enteric nervous system and whether CHD8-associated gastrointestinal complaints are solely due to impaired neuronal function in the intestine. Here, utilizing a stable chd8 mutant zebrafish model, we found that the loss of chd8 leads to reduced number of vagal neural crest cells (NCCs), enteric neural progenitors, emigrating from the neural tube and their early migration capability was altered. At later stages, although the intestinal colonization by the NCCs was complete, we found decreased numbers of both NCC-derived serotonergic neurons and serotonin-producing enterochromaffin cells, suggesting an intestinal hyposerotonemia in absence of chd8. Moreover, transcriptomic analyses revealed altered expression of key receptors and enzymes in serotonin and acetylcholine signaling pathways. Next, tissue examination of chd8 mutants revealed thinner intestinal epithelium accompanied by accumulation of neutrophils and decreased numbers of goblet cells and eosinophils. Last, single-cell sequencing of whole mid- and posterior intestines showed a global disruption of the immune balance with perturbed expression of inflammatory interleukins and changes in immune cell clusters. Our findings propose a causal developmental link between chd8, NCC development, intestinal homeostasis, and autism-associated gastrointestinal complaints.

THE MANAGEMENT OF DERMATITIS HERPETIFORMIS BY THE GASTROENTEROLOGIST. A SERIES OF CASES

ABSTRACT BACKGROUND: Dermatitis herpetiformis (DH) is considered a skin celiac disease (CD). The individuals can be seen by primary care professionals or by dermatologists that could refer the patient to a gastroenterologist. OBJECTIVE: The study aimed to investigate the clinical profile of patients diagnosed with DH and referred to a gastroenterologist and evaluate the treatment response. METHODS: We retrospectively studied patients with DH referred to the same gastroenterologist at a private office in Curitiba, Brazil, between January 2010 to December 2019. We included adult patients with a confirmed DH diagnosis. Symptoms, clinical signs, laboratory and histological data, as well as treatment response, were collected. RESULTS: Thirty-three patients were studied (60.6% women, mean age at diagnosis 40.8±12.61 years). The median delay for DH diagnosis was four years. Skin involvement was mild in 33.3%, moderate in 18.2%, and severe in 48.5%. The more frequent gastrointestinal complaints were abdominal distension (78.8%), flatulence (75.7%), and gastroesophageal reflux (51.5%). Depression and anxiety were observed in 81.8% and anemia in 51.1%. A higher prevalence of bone disorders was associated with higher age at DH diagnosis (P=0.035). Duodenal biopsy showed changes in all patients. Improvement after treatment only with a gluten-free diet (GFD) plus dapsone was verified in 81.2%. CONCLUSION: Patients with DH referred to a gastroenterologist showed a high frequency of gluten intolerance and systemic complaints. Duodenal histological alterations were found in all the cases. The treatment based on GFD plus dapsone was effective in most patients.

Norovirus Epidemiology and Genetic Diversity in Leipzig, Germany during 2013–2017

Globally and in all age groups, noroviruses are a main cause of gastroenteritis. To assess their local epidemiology and genetic diversity, stool samples of 7509 inpatients with gastrointestinal complaints from all age groups were analyzed. After detection of norovirus genogroup I and II RNA by real-time RT-PCR, viral capsids were genotyped by partial nucleic acid sequencing. In the case of GII.2 strains, polymerase genotypes were also assessed. Between October 2013 and September 2017, presence of norovirus RNA was shown in 611 samples (8.1%), of which 610 (99.8%) were typed successfully. Norovirus positivity rate was higher in patients aged below five years (14.8%) than in older patients (5.7%). Among the 611 norovirus positive samples, GII.4 (56.6%) strains prevailed, followed by GII.6 (11.3%), GII.3 (11.0%) and GII.2 (9.5%). The most common genogroup I (GGI) genotype was GI.3 (3.6%). In addition, rare genotypes such as GII.13, GII.14 and GII.26 were detected. Interestingly, GII.3 infections were most common in children under the age of five years. Assessment of polymerase genotypes in GII.2 viruses showed a shift from P2 to P16, with higher diversity in P2 sequences. The varying distribution of norovirus genotypes depending on season, age and setting of infection highlights the importance of frequent genotyping as a basis for vaccine development and needful adjustments.

1557 Readmission Rates Are Not A Surrogate for Poor Practice – An Audit of Readmissions to An Emergency Surgical Unit [Emsu]- The Devil Lies in The Detail!

Aim Readmission rates are considered an indicator of poor performance resulting in financial penalty to healthcare trusts. The national peer review figure for monthly readmission varies considerably (1.71%-7.53%). This metric can be misleading and requires detailed analysis. The aim of this audit was to critically review the readmissions to the EMSU. Method A 1-month review of all patients presenting to the EMSU via a prospectively maintained electronic database was interrogated. (October 2020). The primary outcome was “true” readmission rate (i.e., inclusion criteria - readmission within 30 days of discharge). Secondary outcomes were to assess the appropriateness of readmission and consequent morbidity. Results 331 patients were admitted with 39 readmissions (11.8%). 22 patients failed to meet the inclusion criteria. The true readmission rate was 17 (5.1%). 7/17 had a post-operative complication. The remainder had a miscellaneous minor upper and lower gastrointestinal complaints. 6/10 required cross-sectional imaging and blood work. There were no mortalities. Conclusions The readmission rate reported by Trust coding was erroneously high due to inaccurate recording of data. The accurate readmission rate was 5.1%. The majority of those readmitted could have been managed successfully in a Surgical Ambulatory Service [SAmS]. These data support the hypothesis that readmission rates can be misleading, and efforts should be directed not just in data recording and analysis but also in the utilization of SAmS.

The Ethnobotany and Chemistry of South African Meliaceae: A Review

Meliaceae are widely distributed across the world in tropical or subtropical climates and are of considerable ethnobotanical importance as sources of traditional medicine and cosmetics. This comprehensive review summarizes the ethnobotanical uses and chemistry of 12 South African species, belonging to six genera: Ekebergia, Nymania, Entandrophragma, Pseudobersama, Trichilia, and Turraea. Eight of the species have ethnomedicinal records, classified into 17 major disease categories. The ethnomedicinal uses comprise 85 ailments dominated by gastrointestinal complaints, followed by gynaecological and obstetrics related problems. Chemical records were found for 10 species, which describe nine classes of compounds. In nearly all South African Meliaceae, limonoids are the predominant constituents while triterpenes, sterols, and coumarins are also common. The widest range of use-records and medicinal applications are found with the two most chemically diverse species, Ekebergiacapensis and Trichiliaemetica. Of the chemical compounds identified in the various plant organs of the 10 species of South African Meliaceae for which data are available, 42% was found in bark and 17% in seeds. Roots represent 35% and bark 33% of the organs that are used medicinally, and they are typically prepared as decoctions or infusions. Root and bark harvesting are destructive so that it may be important to examine the chemistry of plant parts such as wild-crafted leaves and fruits.
