AbstractRecent advances in society have resulted in the emergence of both hyperlipidemia and obesity as life-threatening conditions in people with implications for various types of diseases, such as cardiovascular diseases and cancer. This is further complicated by a global rise in the aging population, especially menopausal women, who mostly suffer from overweight and bone loss simultaneously. Interestingly, clinical observations in these women suggest that osteoarthritis may be linked to a higher body mass index (BMI), which has led many to believe that there may be some degree of bone dysfunction associated with conditions such as obesity. It is also common practice in many outpatient settings to encourage patients to control their BMI and lose weight in an attempt to mitigate mechanical stress and thus reduce bone pain and joint dysfunction. Together, studies show that bone is not only a mechanical organ but also a critical component of metabolism, and various endocrine functions, such as calcium metabolism. Numerous studies have demonstrated a relationship between metabolic dysfunction in bone and abnormal lipid metabolism. Previous studies have also regarded obesity as a metabolic disorder. However, the relationship between lipid metabolism and bone metabolism has not been fully elucidated. In this narrative review, the data describing the close relationship between bone and lipid metabolism was summarized and the impact on both the normal physiology and pathophysiology of these tissues was discussed at both the molecular and cellular levels.

Background; Hyperglycemia as a medical condition due to diabetes or other underlying conditions like Stress-Induced Hyperglycemia and sepsis as a life-threatening medical condition are two of the challenges faced during burn treatment. The purpose of this study was to evaluate the risk for sepsis and mortality for the patients with critical hyperglycemic values during the disease. Material and Methods; This is an observational retrospective cohort study conducted in the Service of Burns of the University Hospital Centre “Mother Teresa” in Tirana (UHCT), Albania from 1st January 2010 to 31st December 2014. Patients were categorized as having euglycemia (mean BG values ranging from 80-120 mg/dl), moderate hyper Sepsis was defined according to the ABA Consensus Panel Publication for Infection and Sepsis glycemia (mean BG values <180 mg/dl) or critical hyperglycemia (mean BG values ≥180 mg/dl). to evaluate the impact of the presence of critical hyperglycemia during the disease in sepsis and mortality, we performed Relative risk, Odds ratio Results; Those who had overall hyperglycemia (Moderate and Critical) had 2.6 times the risk for sepsis compared to those who were in the euglycemia group. Analyzing the risk of mortality in patients with overall hyperglycemia during the disease, we observed that the chance of a bad outcome was 2.7 times more likely to occur if the patient had hyperglycemia (RR=2.7). Conclusions: Glucose values on admission, as one of the derangement features of burn shock, are prognostic factors in critical hyperglycemia during burn disease and have a close relationship with other outcomes (sepsis and mortality).

The Impact

Silage is fed to horses in China and other areas in the world, however, knowledge about the impact of feeding silage on horse health is still limited. In the current study, 12 horses were assigned into two groups and fed ryegrass silage and ryegrass hay, respectively, for 8 weeks. High-throughput sequencing was applied to analyze fecal microbiota, while liquid chromatography–tandem mass spectrometry (LC–MS/MS) based metabolomics technique was used for blood metabolite profile to investigate the influence of feeding ryegrass silage (group S) compared to feeding ryegrass hay (group H) on equine intestinal and systemic health. Horses in group S had significantly different fecal microbiota and blood metabolomes from horses in group H. The results showed that Verrucomicrobia was significantly less abundant which plays important role in maintaining the mucus layer of the hindgut. Rikenellaceae and Christensenellaceae were markedly more abundant in group S and Rikenellaceae may be associated with some gut diseases and obesity. The metabolomics analysis demonstrated that ryegrass silage feeding significantly affected lipid metabolism and insulin resistance in horses, which might be associated with metabolic dysfunction. Furthermore, Pearson’s correlation analysis revealed some correlations between bacterial taxa and blood metabolites, which added more evidence to diet-fecal microbiota-health relationship. Overall, ryegrass silage feeding impacted systemic metabolic pathways in horses, especially lipid metabolism. This study provides evidence of effects of feeding ryegrass silage on horses, which may affect fat metabolism and potentially increase risk of insulin resistance. Further investigation will be promoted to provide insight into the relationship of a silage-based diet and equine health.

The Impact

Besides the well-known loss of motor and sensory capabilities, people with spinal cord injury (SCI) experience a broad range of systemic and metabolic abnormalities including, among others, dysfunction of cardiovascular, respiratory, gastrointestinal, urinary, and endocrine systems. These alterations are a significant challenge for patients with SCI because such disorders severely interfere with their daily living and can be potentially life-threatening. Most of these disorders are associated with impairment of regulation of the autonomic nervous system, arising from disruption of connections between higher brain centers and the spinal cord caudal to the injured zone. Thus, the higher and more complete the lesion, the greater the autonomic dysfunction and the severity of complications.This article summarizes the medical scientific literature on key systemic and metabolic alterations derived of SCI. It provides information primarily focused on the pathophysiology and clinical presentation of these disorders, as well as some guides to prevent and alleviate such complications. Due to the impact of these alterations, this topic must be a priority and diffuse to those involved with the care of people with SCI, including the patient himself/herself. We consider that any collaborative effort should be supported, like the development of international standards, to evaluate autonomic function after SCI, as well as the development of novel therapeutic approaches.

This paper supports the hypothesis that corruption and non-delivery of services in key sectors such as health have gender-specific poverty consequences. The study utilized qualitative micro-level information about the structures of corruption and its impact on poor women. Respondents expressed their perceptions on the occurrence of corrupt practices in public health care system and its wider impact on society. The findings revealed that the impact of corruption is felt disproportionately by women and the poor, who are most dependent on public services, and have no alternative even when facing corrupt practices in a life threatening situation, such as complicated birth delivery. Pregnant women denied access to doctors tended to deliver at home, which increased the likelihood of complications and maternal and child mortality. Medical supplies meant for public hospitals are sold to private clinics who charge more for drugs and supplies. There is need to strengthen sectoral oversight mechanisms and transparency as well as increase women’s voices in service delivery.

Two clinical cases of meconium peritonitis in the fetuses are presented. The diagnosis was made prenatally at 30+5 and 20+1 weeks of gestation. The main ultrasound signs were ascites, loop expansion and thickening of the intestinal wall, peritoneal calcifications, meconium pseudocysts. In one case, pregnancy was complicated by polyhydramnios. In both cases, the pregnancy ended in premature birth, followed by surgical treatment during the first days of life. A review of the literature on the topic are discussed the etiology, the spectrum and frequency of ultrasound signs suggesting this condition in the fetus, the effectiveness of prenatal diagnosis, the prognosis for the life and health of the newborn, as well as the impact of the quality and timeliness of the prenatal diagnosis on the management of pregnancy and timeliness of surgical care for the newborn.

The Impact

: Several minimally invasive surgical procedures have been recently developed to treat hemorrhoids without any excision. About 25 years ago, a non-excisional procedure providing doppler-guided ligation of the hemorrhoidal arteries has been proposed - named “hemorrhoidal dearterialization”. The original technique has been modified over the years, and indications were expanded. In particular, a plication of the redundant and prolapsing mucosa/submucosa of the rectum (named “mucopexy”) has been introduced to treat hemorrhoidal prolapse, without excision of the hemorrhoidal piles. At present, the THD® Doppler procedure is one of the most used techniques to treat hemorrhoids. Aim of this technique is to realize a target dearterialization, using a Doppler probe with the final purpose to reduce the arterial overflow to the hemorrhoidal piles. In case of associated hemorrhoidal prolapse, a mucopexy is performed together with Doppler-guided dearterialization. The entity and circumferential extension of the hemorrhoidal prolapse guides the mucopexy, which can be considered tailored to a single patient; the dearterialization should be considered mandatory. Advantages of this surgical technique are the absence of serious and life-threatening postoperative events, chronic complications, and limited recurrence risks. The impact of the procedure on the anorectal physiology is negligible. However, a careful postoperative management is mandatory to avoid complications and to guarantee an improved long-term outcome. Therefore, regular physiologic bowel movements, excessive strain at the defecation and strong physical activity are advisable.

AbstractShort CommunicationsEXIT (ex-utero intrapartum treatment) procedure is a fetal survival-increasing modification of cesarean section. Previously we found an increase incidence of fetal vascular malperfusion (FVM) in placentas from EXIT procedures which indicates the underlying stasis of fetal blood flow in such cases. This retrospective analysis analyzes the impact of the recently introduced CD34 immunostain for the FVM diagnosis in placentas from EXIT procedures.Objectives and MethodsA total of 105 placentas from EXIT procedures (48 to airway, 43 to ECMO and 14 to resection) were studied. In 73 older cases, the placental histological diagnosis of segmental FVM was made on H&E stained placental sections only (segmental villous avascularity) (Group 1), while in 32 most recent cases, the CD34 component of a double E-cadherin/CD34 immunostain slides was also routinely used to detect the early FVM (endothelial fragmentation, villous hypovascularity) (Group 2). 23 clinical and 47 independent placental phenotypes were compared by χ2 or ANOVA, where appropriate.ResultsThere was no statistical significance between the groups in rates of segmental villous avascularity (29 vs. 34%), but performing CD34 immunostain resulted in adding and/or upgrading 12 more cases of segmental FVM in Group 2, thus increasing the sensitivity of placental examination for FVM by 37%. There were no other statistically significantly differences in clinical (except for congenital diaphragmatic hernias statistically significantly more common in Group 2, 34 vs 56%, p=0.03) and placental phenotypes, proving the otherwise comparability of the groups.ConclusionsThe use of CD34 immunostain increases the sensitivity of placental examination for FVM by 1/3, which may improve the neonatal management by revealing the increased likelihood of the potentially life-threatening neonatal complications.

AbstractThe aberrant classical miRNAs are considered to play significant roles in tumor progression. However, it remains unclear for nonclassical miRNAs, a set of Drosha-independent miRNAs in the process of various biology. Here, we reveal that a nonclassical miR-4646-5p plays a pivotal role in gastric cancer (GC) metastasis. MiR-4646-5p, one of Drosha-independent mirtronic miRNA, is aberrant up-regulated in Drosha-low expressed GC and Drosha-knockdown gastric cancer cells. Mirtronic miR-4646-5p is a specific transcription splicing product of intron 3 of the host gene Abhd16a with the aid of SRSF2. The enhanced miR-4646-5p can stabilize HIF1A by targeting PHD3 to positive feedback regulate Abhd16a and miR-4646-5p itself expressions. ABHD16A, as an emerging phosphatidylserine-specific lipase, involves in lipid metabolism leading to lysophosphatidylserines (lyso-PSs) accumulation, which stimulates RhoA and downstream LIMK/cofilin cascade activity through GPR34/Gi subunit, thus causes metastasis of gastric cancer. In addition, miR-4646-5p/PHD3/HIF1A signaling can also up-regulate RhoA expression and synergistically promote gastric cancer cell invasion and metastasis. Our study provides new insights of nonclassical mirtronic miRNA on tumor progress and may serve as a new diagnostic biomarker for gastric cancer. MiR-4646-5p and its host gene Abhd16a mediated abnormal lipid metabolism may be a new target for clinical treatment of gastric cancer.
