[Multidisciplinary regenerative treatment and mechanisms for rescuing a severe calciphylaxis patient with human amnion-derived mesenchymal stem cells].

Calciphylaxis is a rare disease with severe pain and high-mortality due to cutaneous ischemic necrosis and infection that currently lacks proved effective therapies. The occurrence of calciphylaxis in end stage kidney disease (ESKD) patients is known as calcific uremic arteriolopathy (CUA), which is characterized histologically by dermal microvessel calcification, intimal fibroplasia and microthrombosis. Here we innovatively treated a severe CUA patient with human amnion-derived mesenchymal stem cells (hAMSCs). A 34-year-old uremic woman was presented with progressive, painful malodorous ulcers in buttocks and mummified lower limbs. Skin pathological features supported the diagnosis of calciphylaxis. The patient was refractory to conventional multidisciplinary symptomatic therapies. With the approval of our hospital ethics committee, she was treated with hAMSCs including intravenous and local intramuscular injection, and external application of hAMSC culture supernatant to the wound area. During 15-month follow-up, the patient had regeneration of skin and soft tissues, with improved blood biochemical, inflammatory, mineral and bone metabolic indices and immunoregulation effects. After 15-month hAMSC treatment, the score of pain visual analog scale (VAS) decreased from 10 to 0, Bates-Jensen wound assessment tool (BWAT) score decreased from 65 to 13, and wound-quality of life (Wound-QoL) questionnaire score decreased from 68 to 0. We propose that hAMSC treatment is promising for CUA patients. The therapy is potentially involved in the multiple beneficial effects of inhibiting vascular calcification, stimulating angiogenesis and myogenesis, modulating adverse inflammatory and immunologic responses, promoting re-epithelialization and restoring skin integrity.

Treating strangeness: Medicine and human dignity at the time of COVID-19.

The concomitance of a migratory wave and the hospital crisis once again raises the question of the care that the French healthcare system is able to provide to migrants. On the occasion of SFFEM's 19th annual day, we present a synthesis of the research work that has been communicated at that time. Firstly, we will discuss how doctors have been able to overcome strangeness to revive the notion of hospitality according to Levinas; secondly, we will discuss how the hospital is departing from its mission of institutional hospitality because of administrative injunctions; thirdly, we will discuss how ethnomedicine gives us keys to open up to other cultural norms; fourthly, we will see the inadequacy that exists between rights of access to medical care and their effectiveness; finally, the conclusion of Xavier Emmanuelli, founder of the social ambulance service, will remind us how much the values of the French Republic call us to the notion of care and openness to otherness.

The complete chloroplast genome of 'Yulinglong' (Narcissus tazetta var. chinensis) with double-petaled in southeast of China.

In this study, the complete chloroplast (cp) genome of Narcissus tazetta var. chinensis cv 'Yulinglong' was sequenced and assembled by next-generation sequencing. The complete cp genome is 159,376 in length and contained 137 genes, consisting of 91 protein-coding genes, eight ribosomal RNA genes, and 38 transfer RNA genes. Phylogenetic analyses based on chloroplast genomes highly supported that 'Yulinglong' was evolutionarily close to Narcissus tazetta subsp.chinensis, which may provide more desirable information for the phylogenetic relationship between Narcissus tazetta var. chinensis and its relative species.

MiR-532-5p acts as a tumor suppressor and inhibits glioma cell proliferation by targeting CSF1.

OBJECTIVE: Recent studies have discovered a class of micro-RNAs (miRNAs), which are dysregulated in various tumors and associated with carcinogenesis. In our research, we aim to uncover the molecular functions of miR-532-5p in glioma development. PATIENTS AND METHODS: Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) was performed to detect miR-532-5p expression in 48 glioma samples and 4 glioma cell lines. The Pearson's Chi-square test was used to determine the association of miR-532-5p expression with several clinicopathological indexes in glioma patients. Besides, cell proliferation assay, colony formation assay, and Ethynyl deoxyuridine (EdU) incorporation assay were performed to explore in vitro effects of miR-532-5p on glioma cells. Furthermore, the interaction between miR-532-5p and CSF1 in glioma was studied by performing Western blot assay and Dual-Luciferase Reporter Gene Assay. RESULTS: Downregulated miR-532-5p expression was observed in glioma tissues compared with adjacent normal samples. MiR-532-5p expression was associated with the KPS score and tumor grading in glioma patients. Moreover, cell proliferation of glioma was inhibited after overexpression of miR-532-5p in vitro. Furthermore, CSF1 was a target of miR-532-5p in glioma. After overexpression of miR-532-5p, CSF1 was downregulated at mRNA and protein levels in vitro Besides, the expression of CSF1 in glioma tissues was negatively related to that of miR-532-5p. CONCLUSIONS: Malignant phenotypes of glioma cells were remarkably suppressed through the overexpression of miR-532-5p. MiR-532-5p/CSF1 axis was identified as a new therapeutic intervention for the treatment of glioma.

Angiotensin receptor blocker vs ACE inhibitor effects on HDL functionality in patients on maintenance hemodialysis.

BACKGROUND AND AIMS: Angiotensin receptor blockers (ARB) and angiotensin converting enzyme inhibitors (ACEI) reduce cardiovascular events in the general population. Maintenance hemodialysis (MHD) patients are at high cardiovascular risk but few studies have directly addressed the comparative efficacy of these drugs. MHD disrupts the normally atheroprotective actions of high density lipoprotein (HDL), therefore, we compared ACEI or ARB treatment on HDL functions in MHD. METHODS AND RESULTS: HDL was isolated at the starting point (pre) and 3-6 months later (post) in 30 MHD randomly assigned to placebo, ramipril or valsartan. Outcomes included cholesterol efflux, inflammatory cytokine response, effects on Toll-like receptors (TLR), superoxide production, methylarginine and serum amyloid A (SAA) levels. HDL from ARB- or ACEI-treated subjects was more effective in maintaining efflux than HDL of placebo. HDL from ARB- or ACEI-treated subjects but not placebo lessened cellular superoxide production. In contrast, neither ARB nor ACEI improved HDL anti-inflammatory effect. Indeed, HDL of ACEI-treated subjects potentiated the cytokine responses in association with activation of TLR but did not alter the HDL content of methylarginines or SAA. CONCLUSION: Both ACEI and ARB stabilized HDL cholesterol acceptor function and sustained cellular anti-oxidative effects but not anti-inflammatory effects, and ACEI-treatment instead amplified the HDL inflammatory response. The findings reveal possible utility of antagonizing angiotensin actions in MDH and suggest a possible mechanism for superiority of ARB vs ACEI in the setting of advanced kidney disease.

The effect of metabolic syndrome on postoperative outcomes following laparoscopic colectomy.

BACKGROUND: Among the criteria used to diagnose metabolic syndrome (MS), obesity and diabetes mellitus (DM) are associated with poor postoperative outcomes following colectomy. MS is also associated with colorectal cancer (CRC) and diverticulosis, both of which may be treated with colectomy. However, the effect of MS on postoperative outcomes following laparoscopic colectomy has yet to be clarified. METHODS: In an academic tertiary hospital, data from all consecutive patients undergoing laparoscopic colectomy from 2005 to 2014 were prospectively recorded and analysed. Patients presenting with MS [defined by the presence of three or more of the following criteria: elevated blood pressure, body mass index > 28 kg/m2, dyslipidemia (decreased serum HDL cholesterol, increased serum triglycerides) and increased fasting glucose/DM] were compared with patients without MS regarding peri-operative outcome [mainly anastomotic leaks, severe postoperative complications (Clavien-Dindo III and IV)] and mortality. RESULTS: Overall, 1236 patients were included: 508 (41.1%) right colectomies and 728 (58.9%) left colectomies. Seven hundred seventy-two (62.4%) of these procedures were performed for CRC. MS was diagnosed in 85 (6.9%) patients, who were significantly older than the others (70 vs. 64.2 years, p < 0.001), and presented with more cardiac comorbidities (p < 0.001). MS was associated with increased blood loss (122.5 vs. 79.9 mL p = 0.001) and blood transfusion requirement (5.9 vs. 1.7%, p = 0.021). The anastomotic leak rate was 6.6% (with 2.2% of anastomotic leaks requiring surgical treatment), and the overall reoperation rate was 6.9%. The incidence of severe postoperative complications was 11.5%, and the overall mortality rate 0.6%. No differences were found between the groups in overall postoperative morbidity and mortality. Median length of stay was similar in both groups (7 days). CONCLUSIONS: MS does not jeopardize postoperative outcomes following laparoscopic colectomy.

Adrenal ectopy of adult groin region: a systematic review of an unexpected anatomopathologic diagnosis.

PURPOSE: Adrenal ectopy is a rare condition, caused by abnormal embryological development of the adrenal glands and testis. This anomaly is asymptomatic and is generally diagnosed in childhood. Most cases of adrenal ectopy of the groin region have been found incidentally during surgery. This review aims to evaluate the incidence of adrenal ectopy of the adult groin region, as well as its short- and long-term significance. METHODS: A systematic literature search was performed using the EMBASE, MEDLINE, PubMed and Cochrane Central databases to identify all studies published until December 2015. Articles written in English containing the keywords: ''ectopic adrenal tissue'' or ''aberrant adrenal tissue'' or ''adrenal heterotopy'' combined with ''groin region'' or ''inguinal'' or ''testicular" or "scrotum" and "adult" were selected. RESULTS: Fifteen articles matched the review criteria. A total of 21 cases (100 % male) were included. No cases of bilateral nodules have been reported. The mean age at diagnosis was 43.5 years old (range 19-78 years). A predominance of right-sided lesions was observed (71.4 %). The mean size reached 7.6 mm (range 2-40 mm) and hernia sacs were the most common location (47.6 %). All histological analyses of harvested tissues consisted of adrenal cortex without medulla. CONCLUSIONS: Our results suggest that routine pathological examination of any groin tissue excised during inguinal hernia repairs is required for the diagnosis of adrenal ectopy in the groin. Although there is no current evidence that endocrine or oncologic complications can occur from excision of ectopic adrenal tissue, further confirmatory studies may be required.

[Analysis of morphologic changes of lamina cribrosa in primary open angle glaucoma using enhanced depth imaging optical coherence tomography].

OBJECTIVE: To analyze the morphologic changes of the lamina cribrosa (LC) in primary open angle glaucoma (POAG) patients using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS: This was a case-control study. Serial horizontal and vertical B-scans of the optic nerve head were obtained from one eye of 52 POAG patients and 50 age- and sex-matched healthy subjects by EDI-OCT. The number and location of focal LC defects as well as their relationship with retinal nerve fiber layer(RNFL) defects were investigated in glaucomatous eyes and compared with healthy controls. The LC thickness was measured at the center of mid-superior, central, and mid-inferior horizontal B-scans. The intra- and interobserver reproducibility were evaluated by intraclass correlation coefficient (ICC). A repeated measure ANOVA was used to analyze regional differences of the LC thickness. Independent t-test was conducted to compare LC thickness between POAG and healthy controls. A Pearson correlation was calculated for variation in LC thickness relative to global mean RNFL thickness. Spearman rank correlation was calculated to test the strength of the relationship between LC thickness and visual field mean deviation (MD). RESULTS: Twenty-six focal LC defects were found in 20 eyes (38.5%) with glaucoma versus none in the healthy controls. There were 13 (50.0%) focal LC defects in the inferotemporal sector, 6 (23.1%) defects in the inferior sector, 4 (15.4%) in the superotemporal sector, and 3 (11.5%) in the superior sector. Twenty-five of 26 focal LC defects (96.2%) corresponded to the RNFL defects. The intra- and interobserver ICCs of LC thickness measurement ranged from 0.90 to 0.95 and 0.84 to 0.90, respectively. The thicknesses of the superior midperipheral, central, and inferior midperipheral LC in POAG eyes were 180.7±26.3, 196.7±24.0, and 184.1±23.5 µm, respectively. In healthy controls, the laminar thicknesses were 203.2±21.0, 225.2±22.7, and 202.6±16.5 µm, respectively. In both groups, the midperipheral LC was significantly thinner than the central LC (P<0.01). The mean LC thickness was (187.2±19.4) µm in POAG eyes. It was significantly thinner than that in healthy controls (210.3±17.4 µm) (t=5.06, P<0.01). The superior midperipheral, central, and inferior midperipheral regions of the LC were also significantly thinner in POAG than in controls (t=3.52 to 4.96, P<0.01). In POAG patients, mean LC thickness was found to significantly correlate with both global mean RNFL thickness (r=0.45, P<0.01) and visual field MD (rs=-0.58, P<0.01). CONCLUSIONS: The LC thickness was thinner in POAG than in healthy eyes, and correlated with the severity of POAG. Focal LC defects occurred frequently in POAG eyes, and might be associated with RNFL defect. EDI-OCT is a useful tool for the evaluation of LC deformation in glaucoma.(Chin J Ophthalmol, 2016, 52: 422-428).

Meta-analysis of drain amylase content on postoperative day 1 as a predictor of pancreatic fistula following pancreatic resection.

BACKGROUND: Drain amylase content in the days immediately after major pancreatic resection has been investigated previously as a predictor of postoperative pancreatic fistula (POPF). Its accuracy, however, has not been determined conclusively. The purpose of this study was to evaluate the accuracy of drain amylase content on the first day after major pancreatic resection in predicting the occurrence of POPF. METHODS: A literature search of the MEDLINE, Embase and Scopus(®) databases to 13 May 2015 was performed to identify studies evaluating the accuracy of drain amylase values on day 1 after surgery in predicting the occurrence of POPF. The area under the hierarchical summary receiver operating characteristic (ROC) curve (AUChSROC ) was calculated as an index of accuracy, and pooled estimates of accuracy indices (sensitivity and specificity) were calculated at different cut-off levels. Subgroup and meta-regression analyses were performed to test the robustness of the results. RESULTS: Thirteen studies involving 4416 patients were included. The AUChSROC was 0·89 (95 per cent c.i. 0·86 to 0·92) for clinically significant POPF and 0·88 (0·85 to 0·90) for POPF of any grade. Pooled estimates of sensitivity and specificity were calculated for the different cut-offs: 90-100 units/l (0·96 and 0·54 respectively), 350 units/l (0·91 and 0·84) and 5000 units/l (0·59 and 0·91). Accuracy was independent of the type of operation, type of anastomosis performed and octreotide administration. CONCLUSION: Evaluation of drain amylase content on the first day after surgery is highly accurate in predicting POPF following major pancreatic resection. It may allow early drain removal and institution of an enhanced recovery pathway.

Food insecurity is associated with diabetes self-care behaviours and glycaemic control.

AIMS: Food insecurity is the 'limited or uncertain availability of nutritionally adequate and safe foods'. Our objective was to examine the association between food insecurity, diabetes self-care and glycaemic control. METHODS: We conducted a cross-sectional analysis of baseline data from adult patients with Type 2 diabetes who were enrolled in a randomized trial evaluating a health literacy-focused diabetes intervention in safety net primary care clinics in middle Tennessee. Food insecurity was assessed with three items from the U.S. Household Food Security Survey. Diabetes self-care behaviours were assessed with the Summary of Diabetes Self-Care Activities Scale, Personal Diabetes Questionnaire and Adherence to Refills and Medication Scale. Glycaemic control was assessed with HbA1c . RESULTS: The sample consisted of 401 participants, 73% of whom reported some level of food insecurity. Food insecurity was significantly associated with self-care behaviours including less adherence to a general diet [Adjusted Odds Ratio (AOR) 0.9, P = 0.02], less physical activity (AOR 0.9, P = 0.04) and with a greater occurrence of medication non-adherence (AOR 1.2, P = 0.002) and calorie restriction (AOR 1.1, P = 0.02). Food insecurity was also associated with worse glycaemic control (adjusted ß = 0.1, P = 0.03). None of the self-care behaviours were significantly associated with HbA1c , limiting the ability to test for self-care as a mechanism linking food insecurity to glycaemic control. CONCLUSIONS: There was a high rate of food insecurity in a sample of patients with Type 2 diabetes who were of low socio-economic status. Food insecurity was associated with less adherence to recommended self-care behaviours and worse glycaemic control.
