Tertiary cytoreductive surgery in recurrent epithelial ovarian cancer: A multicentre MITO retrospective study.

OBJECTIVES: To evaluate the impact of tertiary cytoreductive surgery (TCS) on survival in recurrent epithelial ovarian cancer (EOC), and to determine predictors of complete cytoreduction. METHODS: A multi-institutional retrospective study was conducted within the MITO Group on a 5-year observation period. RESULTS: A total of 103 EOC patients with a ≥6month treatment-free interval (TFI) undergoing TCS were included. Complete cytoreduction was achieved in 71 patients (68.9%), with severe post-operative complications in 9.7%, and no cases of mortality within 60days from surgery. Multivariate analysis identified the complete tertiary cytoreduction as the most potent predictor of survival followed by FIGO stage I-II at initial diagnosis, exclusive retroperitoneal recurrence, and TCS performed ≥3years after primary diagnosis. Patients with complete tertiary cytoreduction had a significantly longer overall survival (median OS: 43months, 95% CI 31-58) compared to those with residual tumor (median OS: 33months, 95% CI 28-46; p<0.001). After multivariate adjustment the presence of a single lesion and good (ECOG 0) performance status were the only significant predictors of complete surgical cytoreduction. CONCLUSIONS: This is the only large multicentre study published so far on TCS in EOC with ≥6month TFI. The achievement of postoperative no residual disease is confirmed as the primary objective also in a TCS setting, with significant survival benefit and acceptable morbidity. Accurate patient selection is of utmost importance to have the best chance of complete cytoreduction.

Changes in insulin sensitivity and secretion after sleeve gastrectomy.

BACKGROUND: Sleeve gastrectomy is indicated for the treatment of obesity and related co-morbidity including diabetes. The dynamic changes in insulin secretion and sensitivity after sleeve gastrectomy are unknown. METHODS: Whole-body insulin sensitivity was measured by the euglycaemic hyperinsulinaemic clamp technique, and insulin secretion by C-peptide deconvolution after an oral glucose tolerance test (OGTT), before and 3, 6 and 12 months after sleeve gastrectomy in morbidly obese subjects. The time course of glucagon-like peptide (GLP) 1, as a marker of insulin secretion following OGTT, was also assessed. RESULTS: Ten patients were included in the study. Median (range) baseline insulin sensitivity (M-value) increased from 84.0 (20.2-131.4) mmol per kg per min at baseline to 122.8 (99.0-179.3) mmol per kg per min at 12 months after surgery (P = 0.015). Fasting insulin sensitivity, measured by homeostatic model assessment of insulin resistance, which represents a surrogate index of hepatic insulin resistance, decreased from 3.3 (1.9-5.5) to 0.7 (0.5-1.1) mg/dl · µunits/ml (P < 0.001). Total insulin secretion, measured as incremental area under the curve (AUC), after OGTT decreased from 360.4 (347.9-548.0) to 190.1 (10.1-252.0) mmol/l · 180 min at 12 months (P = 0.011). The AUC for GLP-1 increased from 258.5 (97.5-552.6) to 5531.8 (4143.0-7540.9) pmol/l · 180 min at 12 months after sleeve gastrectomy (P < 0.001). In multiple regression analysis, 51 per cent of the M-value variability was explained by GLP-1 secretion. CONCLUSION: Sleeve gastrectomy improved insulin sensitivity and reduced insulin secretion within 6 months after surgery. Although there was a correlation between insulin sensitivity and bodyweight, the major driver of the improvement in insulin sensitivity was GLP-1 secretion.

Adenovirus 36 DNA in human adipose tissue.

Recent studies have suggested a possible correlation between obesity and adenovirus 36 (Adv36) infection in humans. As information on adenoviral DNA presence in human adipose tissue are limited, we evaluated the presence of Adv36 DNA in adipose tissue of 21 adult overweight or obese patients. Total DNA was extracted from adipose tissue biopsies. Virus detection was performed using PCR protocols with primers against specific Adv36 fiber protein and the viral oncogenic E4orf1 protein nucleotide sequences. Sequences were aligned with the NCBI database and phylogenetic analyses were carried out with MEGA6 software. Adv36 DNA was found in four samples (19%). This study indicates that some individuals carry Adv36 in the visceral adipose tissue. Further studies are needed to determine the specific effect of Adv36 infection on adipocytes, the prevalence of Adv36 infection and its relationship with obesity in the perspective of developing a vaccine that could potentially prevent or mitigate infection.

Symptomatic sensorineural hearing loss in patients with ulcerative colitis.

BACKGROUND: Sensorineural hearing loss has been reported as an extraintestinal manifestation of inflammatory bowel disease, especially in adult patients with ulcerative colitis. However, to date only a few series have been reported in the literature, and none from Italy. The aim of the present investigation was to assess the prevalence of symptomatic sensorineural hearing loss in Italian patients with ulcerative colitis. METHODS: We retrospectively assessed the charts of all patients with ulcerative colitis who underwent otolaryngologic investigation in a 10-year period. RESULTS: Complete charts of 57 patients were available for the observation period. Reasons for head and neck investigation were transient, mild hearing loss and sporadic vertigo. Clinical and instrumental head and neck examination was unremarkable in all but one woman who complained of mild hearing loss without vertigo or tinnitus, in whom sensorineural hearing loss was diagnosed. CONCLUSIONS: In our series, sensorineural hearing loss was found in less than 2 % of adult patients with ulcerative colitis evaluated in a department of otolaryngology. Systematic evaluation for this extraintestinal manifestation should not be carried out unless hearing loss is present.

Allelic imbalance in Drosophila hybrid heads: exons, isoforms, and evolution.

Unraveling how regulatory divergence contributes to species differences and adaptation requires identifying functional variants from among millions of genetic differences. Analysis of allelic imbalance (AI) reveals functional genetic differences in cis regulation and has demonstrated differences in cis regulation within and between species. Regulatory mechanisms are often highly conserved, yet differences between species in gene expression are extensive. What evolutionary forces explain widespread divergence in cis regulation? AI was assessed in Drosophila melanogaster-Drosophila simulans hybrid female heads using RNA-seq technology. Mapping bias was virtually eliminated by using genotype-specific references. Allele representation in DNA sequencing was used as a prior in a novel Bayesian model for the estimation of AI in RNA. Cis regulatory divergence was common in the organs and tissues of the head with 41% of genes analyzed showing significant AI. Using existing population genomic data, the relationship between AI and patterns of sequence evolution was examined. Evidence of positive selection was found in 30% of cis regulatory divergent genes. Genes involved in defense, RNAi/RISC complex genes, and those that are sex regulated are enriched among adaptively evolving cis regulatory divergent genes. For genes in these groups, adaptive evolution may play a role in regulatory divergence between species. However, there is no evidence that adaptive evolution drives most of the cis regulatory divergence that is observed. The majority of genes showed patterns consistent with stabilizing selection and neutral evolutionary processes.

Intermittent treatment with mesalazine in the prevention of diverticulitis recurrence: a randomised multicentre pilot double-blind placebo-controlled study of 24-month duration.

BACKGROUND AND AIM: Recurrence of diverticulitis is frequent within 5 years from the uncomplicated first attack, and its prophylaxis is still unclear. We have undertaken a multicentre, randomised, double-blind, placebo-controlled pilot study in order to evaluate the role of mesalazine in preventing diverticulitis recurrence as well as its effects on symptoms associated to diverticular disease. METHODS: Ninety-six patients with the recent first episode of uncomplicated diverticulitis were randomised to receive mesalazine 800 mg twice daily for 10 days every month or placebo for 24 months. The primary efficacy end point was the diverticulitis recurrence at intention to treat analysis. Clinical evaluations were performed using the Therapy Impact Questionnaire (TIQ) for physical condition and quality of life at admission and at 3-month intervals. Treatment tolerability and routine biochemistry parameters as well as the use of additional drugs were also evaluated. RESULTS: Ninety-two patients (mean age, 61.5) completed the study, 45 of whom received mesalazine, and 47, placebo. Diverticulitis relapse incidence in mesalazine-treated group was 5/45 (11%) at the 12th month and 6/45 (13%) at the 24th month; in the placebo-treated group, the correspondent rates were 13% (6/47) and 28% (13/47), respectively. Mean values of TIQ at 24 months were significantly better in mesalazine-treated group than in placebo-treated group (p = 0.02); in addition, average additional drug consumption was significantly lower (-20.4%, p < 0.03) in mesalazine than in placebo. CONCLUSIONS: Diverticulitis recurrence occurred in as many as 28% of patients under placebo within 24 months from the initial episode. Intermittent prophylaxis with mesalazine did not significantly reduce the risk of relapse but induced a significant improvement of patients' physical conditions and significantly lowered the additional consumption of other gastrointestinal drugs.

Transmesenteric hernia after right nephrectomy: diagnostic and therapeutic management.

Internal abdominal hernias are a rare cause of intestinal obstruction (0.2-0.9%). Transmesenteric hernia is a rare type of internal hernia and usually in adult people is acquired. We report the case of a 44 year-old caucasian female with a small bowel occlusion after right nephrectomy for clear cell renal carcinoma caused by an acquired transmesenteric hernia. We emphasize the role of CT scanning for a prompt diagnosis and a quick surgical treatment in order to avoid intestinal gangrene.

Double ileo-ceco-colic invagination due to right colon carcinoma: clinical presentation and management.

Intestinal intussusceptions represent a rare cause of intestinal obstruction in adults (about 1% of intestinal obstructions). The principle causes are benign or malignant tumors. In adults, the most frequent localizations of intestinal invaginations are the ileo-cecal segment, ileum and colon as exclusive localization. We report the case of a 56 year-old Caucasian male admitted in our Department complaining with diffuse abdominal pain and severe anemia. The colonoscopy revealed a vegetant, stenosing and ulcerated mass in the hepatic flexure. The computed tomography suggested the additional diagnosis of intestinal intussusception with no evidence of intestinal obstruction. In our experience, surgery is always indicated for the treatment of intussusceptions in adults, especially for the almost constant underlying neoplasm.

Hyperhomocysteinemia in patients with Crohn's disease.

BACKGROUND: Thromboembolic complications have been reported in patients with Crohn's disease. Among the contributing factors, hyperhomocysteinemia has been described, although controversial data exist. The aim of our study was to assess the incidence of hyperhomocysteinemia in a nonselected group of patients with Crohn's disease and to determine whether it might represent a risk marker for thrombosis in such patients. METHODS: Fifty consecutive patients were recruited, and clinical and laboratory variables were compared between those without and those with hyperhomocysteinemia. In the latter, gene mutations in N5-N10-methyltetrahydrofolate reductase were searched for, and clinical and laboratory variables were related to hyperhomocysteinemia. The presence/absence of thrombotic episodes in both groups was determined. RESULTS: Both groups had similar clinically active disease, with higher C-reactive protein values found in those with hyperhomocysteinemia. Hyperhomocysteinemia was found in 46 % of patients. Of these, 74 % had moderate, 13 % intermediate, and 13 % severe increase in serum homocysteine levels. No relationship was found between homocysteine levels, and age, vitamin B12 levels, folic acid levels, Crohn's Disease Activity Index score, and CRP values. Gene mutations were found in 5 (22 %) patients, 2 homozygotes and 3 heterozygotes. None of the patients with or without hyperhomocysteinemia had episodes of venous or arterial thrombosis, or stroke. CONCLUSIONS: Hyperhomocysteinemia is frequent in patients with Crohn's disease, and it could be a cofactor for the pathogenesis of thrombotic episodes.

The human relevant potency threshold: reducing uncertainty by human calibration of cumulative risk assessments.

The 2008 National Research Council report "Phthalates and Cumulative Risk Assessment: Tasks Ahead," rejected the underlying premises of TEQ-like approaches - e.g., chemicals are true congeners; are metabolized and detoxified similarly; produce the same biological effects by the same mode of action; exhibit parallel dose response curves - instead asserting that cumulative risk assessment should apply dose addition (DA) to all chemicals that produce "common adverse outcomes" (CAOS). Published mixtures data and a human health risk assessment for phthalates and anti-androgens were evaluated to determine how firmly the DA-CAOS concept is supported and with what level of statistical certainty the results may be extrapolated to lower doses in humans. Underlying assumptions of the DA-CAOS concept were tested for accuracy and consistency against data for two human pharmaceuticals and its logical predictions were compared to human clinical and epidemiological experience. Those analyses revealed that DA-CAOS is scientifically untenable. Therefore, an alternative approach was developed - the Human-Relevant Potency-Threshold (HRPT) - that appears to fit the data better and avoids the contradictions inherent in the DA-CAOS concept. The proposed approach recommends application of independent action for phthalates and other chemicals with potential anti-androgenic properties at current human exposure levels.

Laparoscopic sleeve gastrectomy as first stage or definitive intent in 300 consecutive cases.

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) was originally used as a bridge to definitive surgery in high-risk patients. Recently it has been considered as a stand-alone procedure due to its effectiveness on weight loss and comorbidities resolution. This study was designed to evaluate the results of SG on complications, body mass index (BMI), and comorbidities resolution in 300 consecutive obese patients and to analyze the lesson learned from this experience. METHODS: From October 2002 to November 2009, 300 patients underwent SG. In the first 100 cases (group 1: mean BMI, 54.4±9.3), SG was intended as a first stage of biliopancreatic diversion with duodenal switch in high risk super-obese patients. In the last 200 cases (group 2: mean BMI, 45.5±7.3), SG was intended as a definitive procedure. No routine reinforcement was performed in group 1. In group 2, oversewn reinforcement was performed routinely. SG was redo surgery in 21 patients (7%). RESULTS: Mean operative time was 119±48.6 min in group 1 and 72±33.8 in group 2. Conversion rate was 0.6% (massive hepatomegaly). Mortality was 0.6%. Major postoperative complications were registered in 15 patients in group 1 and 11 in group 2. In 3 cases, a reoperation was needed. The mean BMI in group 1 was 46, 43, 39, and 31 at 6, 12, 24, and 36 months, respectively. In group 2, the mean BMI was 32.9, 30.6, and 31.7 at 6, 12, and 18 months. At 12 months, the diabetes, hypertension, and OSAS were cured on 69%, 62%, and 50% in group 1 and 88%, 57%, and 58% in group 2. In group 2, no patient required second stage. CONCLUSIONS: SG is a safe and effective treatment for morbid obesity at mid-term follow-up. SG is effective for comorbidities resolution, especially for the treatment of diabetes. Suture line reinforcement allows a significant reduction of bleeding.

First-phase insulin secretion, insulin sensitivity, ghrelin, GLP-1, and PYY changes 72 h after sleeve gastrectomy in obese diabetic patients: the gastric hypothesis.

BACKGROUND: The aim of this study was to evaluate the possible role of sleeve gastrectomy (SG) per se in the reversibility of diabetes. METHODS: Insulin secretion and peripheral insulin sensitivity using the intravenous glucose tolerance test (IVGTT) were assessed in 18 obese type 2 diabetic patients and in 10 nondiabetic obese patients before and 3 days after SG, before any food intake and any weight change occurrence. At the same time, ghrelin, GLP-1, and PYY levels were determined. RESULTS: In diabetic patients who had the disease less than 10.5 years, the first phase of insulin secretion promptly improved after SG. The early insulin area under the curve (AUC) significantly increased at the postoperative IVGTT, indicating an increased glucose-induced insulin secretion. The second phase of insulin secretion (late AUC) significantly decreased after SG in all groups, indicating an improved insulin peripheral sensitivity. In all groups, pre- and postoperatively, intravenous glucose stimulation determined a decrease in ghrelin values and an increase in GLP-1 and PYY values. However, in the group of patients with disease duration >10.5 years, the differences were not significant except for the late insulin AUC. Postoperative basal and intravenous glucose-stimulated ghrelin levels were lower than preoperative levels in all groups of patients. Basal and intravenous stimulated GLP-1 and PYY postoperative values were higher than preoperative levels in all groups. CONCLUSIONS: Restoration of the first phase of insulin secretion and improved insulin sensitivity in diabetic obese patients immediately after SG, before any food passage through the gastrointestinal tract and before any weight loss, seem to be related to ghrelin, GLP-1, and PYY hormonal changes of possible gastric origin and was neither meal- nor weight-change-related. Duration of the disease up to 10.5 years seems to be a major cut off in the pathophysiological changes induced by SG. A "gastric" hypothesis may be put forward to explain the antidiabetes effect of SG.

Intensified Total Neoadjuvant Therapy in Patients With Locally Advanced Rectal Cancer: A Phase II Trial.

AIMS: We assessed the efficacy and safety of total neoadjuvant therapy, including targeted agent plus FOLFOXIRI (5-fluorouracil, leucovorin, oxaliplatin and irinotecan) induction chemotherapy followed by intensified chemoradiotherapy (CRT) and surgical resection, in patients with locally advanced rectal cancer. MATERIALS AND METHODS: This was a single-arm, single-centre phase II trial. Eligible patients had non-metastatic locally advanced rectal adenocarcinoma. Based on Ras-BRAF status, patients were treated with bevacizumab (mutated Ras-BRAF) or panitumumab/cetuximab (wild-type Ras-BRAF) plus FOLFOXIRI regimen followed by oxaliplatin-5-fluorouracil-based CRT and surgery. The primary end point was pathological complete response rate. Secondary end points were toxicity, compliance, tumour downstaging, complete resection, surgical complications, local and distant failures and overall survival. The sample size was planned to expect an absolute 20% improvement in pathological complete response rate over historical literature data with an α error of 0.05 and a power of 80%. RESULTS: Between October 2015 and September 2019, 28 patients (median age 66 years) were enrolled. All patients had regional lymph node involvement at diagnosis. FOLFOXIRI plus bevacizumab was administered in 11 mutated Ras-BRAF patients, whereas the 17 wild-type Ras-BRAF patients received FOLFOXIRI plus panitumumab/cetuximab. Overall, total neoadjuvant therapy was well tolerated and 26 patients (92.9%) completed the programmed strategy. A complete response was achieved in nine cases (32.1%) and a nearly pathological complete response (ypT1 ypN0) in two patients (7.2%). There was no evidence of febrile neutropenia and no grade 4 adverse events were recorded. Radical resection was achieved in all cases. CONCLUSION: FOLFOXIRI plus targeted agent-based induction chemotherapy and intensified CRT before surgery showed promising clinical activity and was well tolerated in locally advanced rectal cancer patients. This phase II trial provides a strong rationale for phase III studies.

General practitioners' management of symptomatic uncomplicated diverticular disease of the colon by using rifaximin, a non-adsorbable antibiotic.

OBJECTIVE: Symptomatic uncomplicated diverticular disease of the colon (SUDD) is generally managed by gastroenterologists rather than General Practitioners (GPs). The aim of this study was to assess the efficacy of the treatment of SUDD with rifaximin, a non-absorbable antibiotic, in a primary care setting by GPs. PATIENTS AND METHODS: This retrospective, observational study investigated the use of rifaximin at a dose of 400 mg b.i.d. for 5, 7 or 10 days monthly, up to 3 months. The symptoms were reported by the patients using a visual analogic scale (VAS) of 0-10. RESULTS: 286 SUDD patients were enrolled (44.4% of men, average age 70.92±10.98). Respectively, 15 (5.2%) patients received the treatment for 5 days, 205 (71.7%) for 7 days and 66 (23.1%) for 10 days. After three months, a significant reduction of VAS score was observed in almost all symptoms assessed: 135 (47.2%) patients reported no abdominal pain (p<0.001) and 23 (8.1%) reported no symptom. Adverse events related to the treatment were recorded in 3 (1.04%) patients, all of them mild and not requiring interruption of the treatment. Acute diverticulitis occurred in 9 (3.1%) patients, but only 2 of them [0.7% (n=2)] underwent surgery due to complicated diverticulitis. Analysis within the different treatment groups (5, 7 and 10 days) shows that rifaximin treatment is effective in reducing the severity of symptoms in almost all groups except for the constipation in the 5-day group. CONCLUSIONS: Rifaximin can be effectively used by GPs in real-life for the management of SUDD.

Long-term effects of laparoscopic sleeve gastrectomy, gastric bypass, and adjustable gastric banding on type 2 diabetes.

BACKGROUND: This study aimed to compare the efficacy of laparoscopic sleeve gastrectomy (SG) with that of laparoscopic gastric bypass (GBP) and laparoscopic adjustable gastric banding (AGB) for glucose homeostasis in morbidly obese subjects with type 2 diabetes mellitus (T2DM) at a 3-year follow-up assessment and to elucidate the role of weight loss in the T2DM resolution after SG. METHODS: For this study, 60 morbidly obese T2DM patients (44 females and 16 males) who underwent AGB (24 patients), GBP (16 patients), or SG (20 patients) between 1996 and 2008 were retrospectively analyzed. Age, sex, body mass index (BMI), estimated weight loss (EWL), fasting glycemia, HbA1c, euglycemic hyperinsulinemic clamp, discontinuation of diabetes treatment, and time until interruption of therapy were evaluated. RESULTS: In the study, 54 patients received oral hypoglycemic agents for at least 12 months before surgery, and 6 patients received insulin. The mean follow-up period was 36 months. The resolution rate was 60.8% for the AGB patients, 81.2% for the GBP patients, and 80.9% for the SG patients. The postoperative time until interruption of therapy was 12.6 months for the AGB patients, 3.2 months for the GBP patients, and 3.3 months for the SG patients. The hyperinsulinemic euglycemic clamp test was performed 12 months after surgery for the cured patients. Insulin resistance was restored to normal values in all the patients. The greatest improvement from preoperative values occurred in the SG group. For the not-cured GBP and SG patients, an improvement of 120 mg/dl in fasting plasma glucose was observed 3 months after the surgery, suggesting an enhancement in insulin sensitivity, which determines better medical control. The resolution rate remained constant at the 36-month follow-up evaluation in both the GBP and SG groups. CONCLUSIONS: All three bariatric procedures are effective in treating diabetes, with a 3-year follow-up evaluation showing an effect that lasts. The AGB procedure was the least effective. The antidiabetic effect was similarly precocious after GBP and SG compared with AGB. This difference may indicate that a hormonal mechanism may be involved, independent of weight loss.

Colonoscopic findings in coeliac disease on a gluten-free diet.

BACKGROUND: to date, there are few data on colonoscopic findings in patients with celiac disease, and most of these obtained in patients with iron deficiency anaemia. AIMS: we assessed colonoscopic findings in unselected patients with coeliac disease, since there are no studies available also considering morphological aspects, and there is literature suggestion of increased prevalence of colorectal tumours. MATERIAL AND METHODS: colonoscopies with multiple biopsies were retrospectively analyzed in 42 coeliac disease patients on gluten-free diet above age 40; 16 had clinical or laboratory features of iron deficiency anaemia. Mucosal biopsies were evaluated for the presence of intraepithelial lymphocytes and of mucosal eosinophils, in addition to conventional histologic assessment, and compared with those obtained in 15 controls. RESULTS: macroscopic abnormalities (polyps, diverticula, inflammatory changes) were found in 26% of patients. Microscopic abnormalities (lymphocytic colitis, melanosis coli, rectal histiocytosis) were found in 36% of patients. None of these findings was found in controls. Coeliac disease patients had significantly higher eosinophil score than controls in the right colon, whereas this was not significantly different between groups in the left colon. CONCLUSIONS: colonoscopic findings in coeliac disease on gluten-free diet may reveal significant findings, even in patients without iron deficiency anaemia. There is the need of further studies in larger cohorts of patients to establish whether colonoscopy in these patients may be clinically useful.

Bayesian model-based tight clustering for time course data.

Cluster analysis has been widely used to explore thousands of gene expressions from microarray analysis and identify a small number of similar genes (objects) for further detailed biological investigation. However, most clustering algorithms tend to identify loose clusters with too many genes. In this paper, we propose a Bayesian tight clustering method for time course gene expression data, which selects a small number of closely-related genes and constructs tight clusters only with these closely-related genes.

Organization of intensive cardiac care units in Europe: Results of a multinational survey.

BACKGROUND: The present survey aims to describe the intensive cardiac care unit organization and admission policies in Europe. METHODS: A total of 228 hospitals (61% academic) from 27 countries participated in this survey. In addition to the organizational aspects of the intensive cardiac care units, including classification of the intensive cardiac care unit levels, data on the admission diagnoses were gathered from consecutive patients who were admitted during a two-day period. Admission policies were evaluated by comparing illness severity with the intensive cardiac care unit level. Gross national income was used to differentiate high-income countries (n=13) from middle-income countries (n=14). RESULTS: A total of 98% of the hospitals had an intensive cardiac care unit: 70% had a level 1 intensive cardiac care unit, 76% had a level 2 intensive cardiac care unit, 51% had a level 3 intensive cardiac care unit, and 60% of the hospitals had more than one intensive cardiac care unit level. High-income countries tended to have more level 3 intensive cardiac care units than middle-income countries (55% versus 41%, p=0.07). A total of 5159 admissions were scored on illness severity: 63% were low severity, 24% were intermediate severity, and 12% were high severity. Patients with low illness severity were predominantly admitted to level 1 intensive cardiac care units, whereas patients with high illness severity were predominantly admitted to level 2 and 3 intensive cardiac care units. A policy mismatch was observed in 12% of the patients; some patients with high illness severity were admitted to level 1 intensive cardiac care units, which occurred more often in middle-income countries, whereas some patients with low illness severity were admitted to level 3 intensive cardiac care units, which occurred more frequently in high-income countries. CONCLUSION: More than one-third of the admitted patients were considered intermediate or high risk. Although patients with higher illness severity were mostly admitted to high-level intensive cardiac care units, an admission policy mismatch was observed in 12% of the patients; this mismatch was partly related to insufficient logistic intensive cardiac care unit capacity.
