REVIEW
Maria A Sortino, Salvatore Salomone, Michele O Carruba, Filippo Drago
Polycystic ovary syndrome (PCOS) is characterized by hormonal abnormalities that cause menstrual irregularity and reduce ovulation rate and fertility, associated to insulin resistance. Myo-inositol (cis-1,2,3,5-trans-4,6-cyclohexanehexol, MI) and D-chiro-inositol (cis-1,2,4-trans-3,5,6-cyclohexanehexol, DCI) represent promising treatments for PCOS, having shown some therapeutic benefits without substantial side effects. Because the use of inositols for treating PCOS is widespread, a deep understanding of this treatment option is needed, both in terms of potential mechanisms and efficacy...

INTRODUCTION: Owing to the scarcity of randomized controlled trials to guide treatment for decompression illness (DCI), there are many unanswered questions about its management. Apart from reviews and expert opinion, surveys that report practice patterns provide information about useful management strategies. Hence, this study aimed to identify current treatment preferences for DCI amongst diving physicians in Singapore. METHODS: An anonymous web-based questionnaire was sent to known diving physicians in Singapore...

BACKGROUND: Delayed cerebral ischemia (DCI) after subarachnoid hemorrhage (SAH) has been linked to focal reductions in cerebral blood flow (CBF) and microvascular impairments in oxygen delivery. Effective therapies that restore flow and oxygen transport to vulnerable brain regions are currently lacking. SANGUINATE is a dual-action carbon monoxide-releasing and hemoglobin-based oxygen transfer agent with efficacy in animal models of focal brain ischemia and tolerability in patients with sickle cell disease...

A novel ultra-stable metal-organic framework, MCIF-1, [Cu2(DCI)2](MeCN), based on dicyanoimidazole and Cu(i), has been synthesized at room temperature successfully. MCIF-1 shows excellent water stability and can retain crystallinity after soaking in water for about one week. In addition, MCIF-1 also shows exceptional resistance under both acidic and basic conditions within a large pH range from 0 to 13.5. What is more, after modifying the synthesis procedure slightly, we can produce this material in a large scale during a very short time...

OBJECTIVE: Genetic variations of the SERPINE1 gene, which encodes plasminogen activator inhibitor 1 (PAI-1), correlate with serum levels of its product and are associated with thrombophilia and coronary atherosclerosis. Various SERPINE1 gene polymorphisms have been identified. Only the functional 5G/4G polymorphism, however, has been assessed in the context of aneurysmal subarachnoid hemorrhage (aSAH). Here, we assessed associations of 6 SERPINE1 polymorphisms with the clinical sequelae of aSAH...

BACKGROUND: Cerebral vasospasm leading to delayed cerebral infarction (DCI) is a central source of poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Current treatments of cerebral vasospasm are insufficient. Cisternal blood clearance is a promising treatment option. However, a generally applicable, safe, and effective method to access the cisterns of the brain is lacking. OBJECTIVE: To report on stereotactic catheter ventriculocisternostomy (STX-VCS) as a method to access the cisterns of the brain for clearance of subarachnoid hemorrhage in patients with aSAH and coiled aneurysms...

OBJECTIVE Delayed cerebral ischemia (DCI) following subarachnoid hemorrhage (SAH) is one of the major contributors to poor outcome. It is crucial to be able to detect early signs of DCI to prevent its occurrence. The objective of this study was to determine if low cerebral blood flow (CBF) measurements and pathological microdialysis parameters measured at the bedside can be observed early in patients with SAH who later developed DCI. METHODS The authors included 30 patients with severe SAH. The CBF measurements were performed at Day 0-3 after disease onset, using bedside xenon-CT...

The present study aimed to examine whether bereaved parents "meaning-made"-defined as results of attempts to reduce discrepancies between the meaning assigned to the death of the child and self and world-views-was influenced by their own and their partner's coping orientations. Coping orientations were conceptualized within the Dual Process Model, which entails loss coping orientation (LO; focus on the loss itself), restoration coping orientations (RO; focus on stressors that come about as an indirect consequence of the bereavement), and a flexible oscillation between both coping orientations...

BACKGROUND: Although major manometric abnormalities, the significance of esophagogastric junction outflow obstruction (EGJOO) and hypercontractile esophagus (HE) is poorly understood. We sought to determine long term outcomes for EGJOO and HE. METHODS: High-resolution impedance manometry (HRIM) studies conducted from 5/30/2012 to 8/1/2014 consistent with EGJOO and HE and normal studies from 5/30/12 to 11/1/12 were identified. Standardized follow up was conducted with a phone survey utilizing the impact dysphagia questionnaire (IDQ-10)...

BACKGROUND: The current paradigm of measuring esophageal contractile vigor assesses the entirety of a pressure wave using a single measurement, the distal contractile integral (DCI). We hypothesize that an assessment identifying separate phases of the contractile pressure wave before and after the pressure peak may help distinguish abnormalities in patients presenting with chest pain and dysphagia. The aim of the present study was to develop a technique to assess the individual phases and report on the values in healthy controls...

BACKGROUND: Delayed cerebral ischemia (DCI) after subarachnoid hemorrhage (SAH) is one of the main causes of neurological deterioration. However, it frequently evades timely detection. Early identification and effective reversal may improve the clinical outcome. In this prospective study, we evaluate several serum inflammatory markers after aSAH with regard to the occurrence of DCI. METHODS: On days 1, 4, 7, 10 and 14 after SAH leucocyte count, C-reactive protein, interleukin-6, E-selectin, matrix metallopeptidase 9, intercellular adhesion molecule 1 and leukemia inhibitory factor were assessed in patients´ serum samples...

The etiology and clinical impact of ineffective esophageal motility (IEM) remain poorly understood. Unless gastroesophageal acid reflux (GERD) is identified, symptomatic patients with IEM are challenging to treat. We sought to determine whether any clinical or functional characteristics could distinguish those patients with IEM and either normal or abnormal esophageal acid exposure.In this retrospective cohort study, we identified 46 consecutive patients presenting with heartburn, and other GER symptoms who underwent clinical, endoscopic, and functional evaluation that included high-resolution manometry (HRM) and ambulatory pH monitoring...

BACKGROUND: Delayed cerebral infarction (DCI) is a major cause of morbidities after aneurysmal subarachnoid hemorrhage (SAH) and typically starts at day 4 to 7 after initial hemorrhage. MicroRNAs (miRNAs) play an important role in posttranscriptional gene expression control, and distinctive patterns of circulating miRNA changes have been identified for some diseases. We aimed to investigate miRNAs that characterize SAH patients with DCI compared with those without DCI. METHODS AND RESULTS: Circulating miRNAs were collected on day 7 after SAH in healthy, SAH-free controls (n=20), SAH patients with DCI (n=20), and SAH patients without DCI (n=20)...

Patent foramen ovale (PFO) is thought to be a risk factor for decompression illness (DCI). Catheter-based closure procedure reduces the risk of DCI in selected scuba divers with PFO. Major complication of invasive approach are rare, minor, especially heart rhythm disturbances are reported relatively often. We describe a case of 41-year-old diver, who underwent PFO closure due to recurrent DCI events. Afterward, he experienced no DCI symptoms; however, he complained about feeling of the heart beating during a submersion...
