Multicentric data analysis of the learning curve for laparoscopic Shull's repair of pelvic floor defects.

Introduction: Pelvic organs prolapse remains a significant health concern affecting millions of women worldwide. The use of native tissues to suspend the apex has acquired relevance in urogynecologic surgery. One of the most commonly used procedures performed without mesh is the technique described by Shull, consisting of suturing the vaginal apex to the uterosacral ligaments. The objective of the study is to evaluate the learning curve of laparoscopic Shull's repair for the correction of pelvic floor defects, including the surgery time and surgical outcomes. Materials and methods: This is a retrospective study conducted at the Policlinico G. Martino, University of Messina, Messina, Italy, and Policlinico Vanvitelli, Vanvitelli University, Naples, Italy. All patients affected by grade I-IV POP, consisting of apical prolapse with or without cystocele, and who underwent laparoscopic Shull's technique for prolapse correction were enrolled. The endpoints to estimate the learning curve for the procedure were the percentage of laparoscopic procedures completed, operative time, and the early complication rate. Results: A total of 31 laparoscopic Shull repairs were collected for the study. To evaluate the learning curve of the technique, we divided the 31 cases into three different groups: Procedures 0-10; 11-20; 21-31. The parameter for evaluating technique learning was the operative time. Group 21-31 demonstrated an operative time of 97 min (SD 20), compared with 121 min (SD 23) in group 0-10 and 120 min (SD 13) in group 11-20. A comparison of these means through ANOVA showed a p-value of 0.01 for the entire system, and 0.95 for the comparison between 0 and 10 and 11-20, 0.04 for 0-10 vs. 21-31, and 0.02 between 11 and 20 and 21-31. Conclusions: The rate of surgical improvement in terms of time became effective after an average of 20 procedures. However, the improvement seems to be effective case by case for surgeons skilled in basic endoscopy.

Effects of a similar amount of regular non-structured or competitive physical activity across late adulthood: a cross-sectional study.

Introduction: Master athletes are examples of successful aging. It is not clear whether it is the competitive-oriented training or just the amount of total regular exercise that reduces the age-related decline in physiological functions. We aimed to compare health-related parameters in competitive (C) and physically active older adults (A) that performed the same weekly physical activity (PA) amount. Methods: Seventeen C and 17 A were matched for age (8 and 9 male participants under and over 70 years old respectively, for both groups) and weekly PA amount (GPAQ). Body composition, leg and arm maximal strength, balance and reaction time were measured; moreover, leg and arm exercise efficiency, estimated VO2max, and VO2/HR relationships were evaluated. Perception of life and sleep quality was also assessed through specific questionnaires (SF-36 and PSQI). The effect of group (C vs. A), age (U70 vs. O70) and their interaction was examined through a Two-Way ANOVA test. Results: C dedicated more time to vigorous PA compared to A (p = 0.03), while less to moderate daily work (p < 0.01) and active commuting (p = 0.06). C exhibited better body composition (all p < 0.05), higher leg maximal strength (p < 0.05) and a trend for elevated arm strength (p = 0.06). Reaction time, leg and arm cycling efficiency were similar in the two groups (all p > 0.05), while balance reduced in A O70. Estimated VO2max was higher for C in leg cycling (p = 0.05) and remained constant across ages (all p > 0.05). VO2/HR relationship, life and sleep quality did not differ for groups and ages. Conclusions: Regular physical exercise of about 6,000 METs/week seems to have a beneficial effect on health-related parameters, both in non-structured and competitive PA, when compared to sedentary behaviour. However, the older adults engaged in competitive training exhibit further advantages: better body composition, higher arm and leg muscle strength, and higher leg VO2max. This study highlights the importance of encouraging active lifestyles for maintaining long-term health, high levels of life quality perception and reducing age-related decline. However, vigorous training suitability needs to be verified by a team of PA specialists.

A case of severe allergic eosinophilic asthma with nasal polyposis in a patient affected by Birt-Hogg-Dubé syndrome successfully treated with benralizumab.

SUMMARY: Birt-Hogg-Dubé (BHD) syndrome is a rare genetic pathology characterized by cutaneous fibrofolliculomas, pulmonary cysts and kidney tumours. Severe asthma is the most serious form of asthma that does not respond to standard treatments. We present the case of a 68 years-old male patient who had frequent respiratory tract infections, shortness of breath and decline in lung function, nasal polyposis and hypertrophy of the nasal turbinates, for this reason was treated as a severe asthmatic patient for several years with ICS + LABA and high doses of OCS. When we tried to reduce OCS the patient had worsening of the symptoms, we requested a HRTC scan that showed presence of several cysts spread ubiquitously. The patient had a family history of pneumothorax, for this reason we requested a genetic test that resulted in a heterozygous point mutation on exon 12 (c.1429 C > T) of FLCN gene. Despite the diagnosis of BHD syndrome, the patient's clinical condition kept on suggesting an underlying severe asthma and the blood tests we requested pointed out a high percentage of eosinophils, for this reason we opted for the administration of benralizumab that resulted in an excellent asthma control and increased quality of life.

A Mycobacterial Systems Resource for the Research Community.

Functional characterization of bacterial proteins lags far behind the identification of new protein families. This is especially true for bacterial species that are more difficult to grow and genetically manipulate than model systems such as Escherichia coli and Bacillus subtilis To facilitate functional characterization of mycobacterial proteins, we have established a Mycobacterial Systems Resource (MSR) using the model organism Mycobacterium smegmatis This resource focuses specifically on 1,153 highly conserved core genes that are common to many mycobacterial species, including Mycobacterium tuberculosis, in order to provide the most relevant information and resources for the mycobacterial research community. The MSR includes both biological and bioinformatic resources. The biological resource includes (i) an expression plasmid library of 1,116 genes fused to a fluorescent protein for determining protein localization; (ii) a library of 569 precise deletions of nonessential genes; and (iii) a set of 843 CRISPR-interference (CRISPRi) plasmids specifically targeted to silence expression of essential core genes and genes for which a precise deletion was not obtained. The bioinformatic resource includes information about individual genes and a detailed assessment of protein localization. We anticipate that integration of these initial functional analyses and the availability of the biological resource will facilitate studies of these core proteins in many Mycobacterium species, including the less experimentally tractable pathogens M. abscessus, M. avium, M. kansasii, M. leprae, M. marinum, M. tuberculosis, and M. ulceransIMPORTANCE Diseases caused by mycobacterial species result in millions of deaths per year globally, and present a substantial health and economic burden, especially in immunocompromised patients. Difficulties inherent in working with mycobacterial pathogens have hampered the development and application of high-throughput genetics that can inform genome annotations and subsequent functional assays. To facilitate mycobacterial research, we have created a biological and bioinformatic resource (https://msrdb.org/) using Mycobacterium smegmatis as a model organism. The resource focuses specifically on 1,153 proteins that are highly conserved across the mycobacterial genus and, therefore, likely perform conserved mycobacterial core functions. Thus, functional insights from the MSR will apply to all mycobacterial species. We believe that the availability of this mycobacterial systems resource will accelerate research throughout the mycobacterial research community.

Effect of red thyme oil (Thymus vulgaris L.) vapours on fungal decay, quality parameters and shelf-life of oranges during cold storage.

This work has been aimed at studying the effect of red thyme oil (RTO, Thymus vulgaris L.) on the shelf-life and Penicillium decay of oranges during cold storage. RTO vapours significantly reduced (P ≤ 0.05) the percentage of infected wounds, the external growth area and the production of spores in inoculated orange fruit stored for 12 days at 7 °C in a polypropylene film selected for its appropriate permeability. Among the RTO compounds, p-cymene and thymol were the most abundant in packed boxes at the end of cold storage. The RTO vapours did not affect the main quality parameters of the oranges, or the taste and odour of the juice. The results have shown that an active packaging, using RTO vapours, could be employed, by the citrus industry, to extend the shelf-life of oranges for fresh market use and juice processing.

Minilaparotomic incision for haemorrhagic corpus luteum: a case report.

Corpus luteum cyst rupture with consequent hemoperitoneum is a common cause of admission to the emergency room. This condition is frequently misdiagnosed because of overlapping of clinical findings in acute gynecologic diseases. However, an incorrect identification may lead to delay in surgical treatment, which can Romabe a life-threatening condition. Ultrasound (US) is the first technique used for diagnosis that can confirm or dismiss the presence of intraperitoneal fluid. Secondly, the contrast-enhanced computed tomography (CT) is the quickest way to identify the site of active bleeding and to establish the correct management of the clinical condition. Herein, we report a case of a 19-years-old girl with acute abdominal pain correctly identified by diagnostic images and treated with mini-invasive surgery techniques in order to quickly act without clinic and aesthetic sequelae.

Clomipramina no tratamento da perseguição compulsiva da cauda em Bull Terrier - relato de caso / Clomipramine in the treatment of compulsive tail pursuit in bull terrier - case report

A perseguição compulsiva da cauda consiste em um distúrbio caracterizado por movimentos giratórios em círculos, lentos a rápidos com ou sem foco na cauda. É uma desordem comportamental comumente observada em cães da raça Bull Terrier, sendo mais frequente em machos, com início entre três e seis meses de idade. O diagnóstico é realizado com base no histórico do paciente junto com exames físico, neurológico e laboratoriais. O tratamento pode ser feito por meio do manejo ambiental e da retirada de fatores estressantes aliados a medicamentos antidepressivos. O objetivo deste artigo é relatar o caso de um Bull Terrier que apresentava perseguição compulsiva da cauda e teve evidente melhora clínica 75 dias após início do tratamento com clomipramina. A melhora foi ainda maior após a orquiectomia. A clomipramina consiste em um antidepressivo tricíclico promissor no tratamento de perseguição compulsiva da cauda em cães, devendo-se associar alteração no manejo ambiental e evitar gatilhos que induzam frustração, ansiedade e conflito.(AU)

The compulsive pursuit of the tail is characterized by a rotating movement in circles, slow to fast with or without focus on the tail. It is a disorder commonly observed in bull terrier dogs, being more frequent in males, beginning between 3 and 6 months of age. Diagnosis can be made based on patient history along with physical, neurological, and laboratory tests. Treatment can be done through environmental management and withdrawal of stressors allied with antidepressant drugs. The objective of this article is to report the case of a Bull Terrier that had compulsive pursuit of the tail and had evident clinical improvement 75 days after starting treatment with clomipramine. The improvement was even greater after orchiectomy. Clomipramine is the promising tricyclic antidepressant in the treatment of compulsive tail chasing in dogs. It should be associated with changes in environmental management and avoid triggers that induce frustration, anxiety and conflict.(AU)

Alternativas diagnósticas de escabiose felina / Diagnostic alternatives of feline scabies

A sarna notoédrica é uma doença altamente pruriginosa, causada pelo ácaro Notoedres cati. O diagnóstico consiste na observação do ácaro no material analisado, sendo o raspado cutâneo o método mais utilizado. Outras técnicas têm surgido como alternativas menos invasivas no diagnóstico de sarnas, sobretudo para demodicose em cães, como a de fita de acetato e o arrancamento de pelos, que vêm se mostrando tão sensíveis quanto o raspado cutâneo no diagnóstico de tal dermatopatia. Desse modo, o objetivo deste estudo foi comparar o raspado cutâneo com dois métodos alternativos para diagnóstico de sarna notoédrica em gatos: fita de acetato e arrancamento de pelo, sendo possível concluir que o método da fita é tão sensível quanto o raspado cutâneo, ambos apresentando 100% de sensibilidade. A técnica de arrancamento de pelo apresentou sensibilidade significativamente menor para o diagnóstico de Notoedres cati, resultado esperado, uma vez que esse parasita habita principalmente porções superficiais da derme. Assim, o método da fita de acetato pode ser utilizado de forma eficaz e segura para o diagnóstico de sarna notoédrica em gatos, além de ser menos estressante aos animais, mais rápido e simples do que o raspado cutâneo.(AU)

Notoedric mange is a highly pruritic disease caused by the Notoedres cati mite. The diagnosis consists of the observation of the mite in the material analyzed, skin scrapings is the most used method. Other techniques have emerged as less invasive alternatives in the diagnosis of mange, especially for demodicosis in dogs, such as acetate tape and hair removal, which have shown to be as sensitive as skin scrapings in the diagnosis of such dermatopathy. Thus, the objective of this study was to compare skin scaling with two alternative methods for the diagnosis of notohedral scabies in cats: acetate tape and hair collection, and it is possible to conclude that the acetate tape method is as sensitive as skin scraping, both presenting 100% sensitivity. The hair pulling technique showed significantly lower sensitivity for the diagnosis of Notoedres cati, an expected result, since this parasite inhabits mainly superficial portions of the dermis. Thus, the tape method can be used effectively and safely for the diagnosis of notodroid mange in cats, as well as being less stressful to animals, faster and simpler than skin scraping.(AU)

Production of Hydronium Ion (H3O)+ and Protonated Water Clusters (H2O)nH+ after Energetic Ion Bombardment of Water Ice in Astrophysical Environments.

Water ice exists on many objects in space. The most abundant icy species, among them water, are present in the icy satellites of the outer Solar System giant planets. The nuclei of comets, which are mainly composed of water ice, give another example of its abundance. In the interstellar medium (ISM), ice mantles, formed by molecular species sticking on dust grains, consist mainly of water ice. All these objects are exposed to ionizing radiation like ions, UV photons, and electrons. Sputtering of atoms, molecules, ions, and radicals from icy surfaces may populate and maintain exospheres of icy objects in the Solar System. In other respects, ionized hydrides such as OH+, H2O+, and H3O+ have been detected in the gas phase in star-forming regions. Interactions with cosmic rays could be an additional explanation to the current models for the formation of those species. In fact, laboratory simulations showed that the main components of the sputtered ionic species from water ice are oxygen hydrides. In this work, water ice targets were irradiated at several temperatures (10-200 K) by 90 keV O6+ ions, yielding an electronic stopping power of about 12 eV/Å, when the nuclear stopping power is comparable to the electronic stopping power. Sputtering of secondary ions after bombardment of the ice target was analyzed by time-of-flight mass spectrometry (TOF-SIMS). Besides hydrogen ions (H+, H2+, H3+), also O+, O2+, OH+, (H2O)+, and clusters of (H2O)nH+ with n = 1-8 are emitted. Our results show a progressive yield decrease with increasing temperature of all of the detected species. This is related to the structure of the ice: the ionic sputtering yield for crystalline ice is much lower than for an amorphous ice. For instance, amorphous ice at 10 K exhibits a yield of the order of 2 × 10-6 secondary (H2O)nH+ hydride ions/projectile (with n = 1-8). As the temperature is increasing toward the phase transition to crystalline ice, the yields decrease by about one order of magnitude.

Hipoparatireoidismo secundário ao uso prolongado de omeprazol em um cão: relato de caso / Secondary hypoparathyroidism to omeprazole prolonged use in a dog: case report

O hipoparatireoidismo, quer seja primário ou secundário, é uma doença rara em cães, causada pela diminuição da secreção de paratormônio pelas paratireoides, que leva a sinais clínicos resultantes da hipocalcemia. O omeprazol vem sendo cada vez mais utilizado na medicina veterinária visando à diminuição na produção de líquor, mas existem poucos estudos sobre os efeitos colaterais relacionados ao uso crônico dessa medicação. Relata-se o caso de um cão macho da raça Yorkshire Terrier, com quatro anos de idade, com sinais clínicos de dor, sendo verificada calcificação em pelve e divertículo renal. Segundo o proprietário, o cão fazia uso de omeprazol há mais de dois anos devido ao histórico de hidrocefalia. Os exames laboratoriais evidenciaram anemia microcítica hipocrômica, hipocalemia, hiperfosfatemia, hipocalcemia, hipomagnesemia e hipercalciúria. A dosagem do paratormônio sérico confirmou o hipoparatireoidismo. Após a suspensão do omeprazol, as alterações encontradas nos exames se normalizaram, confirmando que a causa do hipoparatireoidismo era o uso crônico da medicação.(AU)

Primary or secondary hypoparathyroidism is a rare disease in dogs caused by the decreased secretion of parathormone from the parathyroid glands, leading to clinical signs of hypocalcemia. Omeprazole has been increasingly used in veterinary medicine in order to reduce the production of cerebrospinal fluid, but there are few reports of side effects related to its chronic use. We report a case of a four-year-old male Yorkshire terrier with clinical signs of pain, calcification in the pelvis and renal diverticulum. According to the owner, the dog had been receiving omeprazole for over 2 years because of the history of hydrocephalus. Hematological exams revealed hypochromic microcytic anemia, hypokalemia, hyperphosphatemia, hypocalcemia, hypomagnesemia besides hypercalciuria. The determination of serum parathyroid hormone concentrations confirmed hypoparathyroidism. After interrupting omeprazole, the altered features on the exams returned to normal values, confirming that the cause of hypoparathyroidism was the chronic use of the drug.(AU)

Mid-IR band strength, density, refractive index, and thermal evolution study for solid CH2DOH pure and in astrophysical relevant mixtures.

We present a novel experimental study on solid CH2DOH pure and in astrophysical relevant mixtures. Solid samples were accreted under ultra high vacuum conditions at 17 K and were analyzed by mid-infrared transmission spectroscopy. Refractive index, density, and mid-IR band strength values were measured for pure solid CH2DOH. The refractive index was also measured for CH2DOH:H2O, CH2DOH:CO, and CH2DOH:CH3OH mixtures. For all samples, the thermal evolution of the main band profile was studied. We used the interference laser technique (HeNe laser, λ = 543.5 nm) to measure the samples thickness and a numerical method to measure the refractive index starting from the amplitude of the interference curve. We obtained the ice density through the Lorentz-Lorenz relation. To calculate the band strength values we used the linear fit of the integrated band intensities with respect to the column densities. Samples deposited at 17 K were warmed up to their sublimation temperature. Spectra were taken at selected temperatures to study their thermal evolution. The results are discussed in view of their relevance for the interpretation of astronomical IR spectra.

Modeling the Effect of High Calorie Diet on the Interplay between Adipose Tissue, Inflammation, and Diabetes.

BACKGROUND: Type 2 diabetes (T2D) is a chronic metabolic disease potentially leading to serious widespread tissue damage. Human organism develops T2D when the glucose-insulin control is broken for reasons that are not fully understood but have been demonstrated to be linked to the emergence of a chronic inflammation. Indeed such low-level chronic inflammation affects the pancreatic production of insulin and triggers the development of insulin resistance, eventually leading to an impaired control of the blood glucose concentration. On the contrary, it is well-known that obesity and inflammation are strongly correlated. AIM: In this study, we investigate in silico the effect of overfeeding on the adipose tissue and the consequent set up of an inflammatory state. We model the emergence of the inflammation as the result of adipose mass increase which, in turn, is a direct consequence of a prolonged excess of high calorie intake. RESULTS: The model reproduces the fat accumulation due to excessive caloric intake observed in two clinical studies. Moreover, while showing consistent weight gains over long periods of time, it reveals a drift of the macrophage population toward the proinflammatory phenotype, thus confirming its association with fatness.

Photolysis of Cometary Organic Dust Analogs on the EXPOSE-R2 Mission at the International Space Station.

We describe the results obtained on a set of organic samples that have been part of the experiment "Photochemistry on the Space Station (PSS)" on the EXPOSE-R2 mission conducted on the EXPOSE-R facility situated outside the International Space Station (ISS). The organic samples were prepared in the Catania laboratory by 200 keV He+ irradiation of N2:CH4:CO icy mixtures deposited at 17 K, on vacuum UV (VUV) transparent MgF2 windows. This organic material contains different chemical groups, including triple CN bonds, that are thought to be of interest for astrobiology. It is widely accepted that materials similar to that produced in the laboratory by ion irradiation of frozen ices could be present in some astrophysical environments such as comets. Once expelled from comets, these materials are exposed to solar radiation during their interplanetary journey. In the young Solar System, some of these processed materials could have reached early Earth and contributed to its chemical and prebiotic evolution. The samples were exposed for 16 months to the unshielded solar UV photons. It was found that, if an interplanetary dust particle (IDP) containing organic material (50% vol) is large enough (>20-30 µm), relevant chemical groups, such as those containing the CN triple bond, can survive for many years (>104 years) in the interplanetary medium.

Intracesarean removal of two huge fibroids occupying the whole uterine fundus: a case report.

Uterine fibroid is an estrogen-dependent mass growing during pregnancy. Caesarean myomectomy (CM) is a controversial procedure. A 35-year-old obese (106 Kg) patient gravida 2 para1 (caesarean section), undergoing caesarean section, had two myomas occupying the whole uterine fundus (104.2 mm and 50 mm respectively). Intracesarean myomectomy was carried out after extraction foetus (Apgar score: 9/10). Postoperative course was uneventful and patient was discharged after four days.

A rare case of trichilemmal ovarian carcinoma. Case report and review of the literature.

Trichilemmal ovarian carcinoma is very rare. A 52-years-old woman was admitted to University Hospital Department suffering from pain in the left iliaca fossa lasting for three months. Uterus was normal in size, painless as well as right adnexum. On the left site ovary was increased in volume and slightly sore. Transvaginal ultrasounds showed a 97x65x86 mm mixed vascularized unilocular mass. CT scan detected a pelvic expansion with a heterogeneous density due to the presence of different structures varying from fat to bone tissue. A proper informed consent was obtained and a suprapubic transversal laparotomy according to Pfannenstiel was carried out. Ovarian mass and ipsilateral tube were removed with no rupture. The anatomical extemporaneous result was of benign dermoid cyst. The postoperative course was uneventful and after three days the patient was discharged in regular conditions and was recommended to come for final anatomical result. Following a month, the final histological answer was of 15 mm trichilemmal malignant tumor in a context of a large benign dermoid cyst. The neoplastic lesion appears to be entirely contained within the limits of the swollen mass. The outer surface was with no lesions. A case of trichilemmal malignant tumor involving ovary has not been published so far.

CT-guided drainage with percutaneous approach as treatment of E. Faecalis post caesarean section severe abscess: case report and literature review.

We report a case of a 32-year old woman with severe pelvic abscess formation who was readmitted to the hospital after ten days of postoperative caesarean course. The patient had undergone emergency caesarean section (CS) for acute foetal sufferance during expulsive period and following three days had been discharged regularly. Enterococcus Faecalis was isolated from purulent material. A prompt antibiotic therapy was carried out, therefore clinic condition did not improve. A percutaneous Computed Tomography (CT)-guided drainage of the abscess was planned. Under local anesthesia abscess was drained. The hospitalization stay allowed monitoring the patient's clinical condition and laboratory blood panel until normalization of all parameters.

Alpha-lipoic acid, but not di-hydrolipoic acid, activates Nrf2 response in primary human umbilical-vein endothelial cells and protects against TNF-α induced endothelium dysfunction.

The antioxidants role in cell response regulation attracted great interest in the last decades and it is undergoing to a profound reconsideration. The mere concept of "biological antioxidant" has been frequently misconceived or misused, possibly leading to the misinterpretation of some experimental observation. Organosulfur compounds in general and α-lipoic acid, a dithiol molecule, can be considered a typical example of the kind. Reduced α-lipoic acid, dehydrolipoic acid has been in fact originally considered a bona fide, reducing, electron donor molecule. A more recent approach, according to stoichiometric and thermodynamic evidences, lead to a reinterpretation of the biochemical role of "antioxidants". The electrophilic nature of oxidized nucleophilic molecules, including α-lipoic acid, renders more plausible a mechanism based on the ability to activate Nrf2/EpRE mediated hormetic response. In this study, we demonstrate that nmolar concentrations of oxidized α-lipoic acid, but not dehydrolipoic acid, protect human umbilical primary endothelial cells (HUVEC) from TNF-α induced dysfunction, inhibit NF-κB activation and block apoptosis following the activation of Nrf2 transcription factor. Our observations corroborate the concept that the major, if not the unique, mechanism by which α-lipoic acid can non-enzymatically exert its reducing activity is related to the electrophilic nature of the oxidized form.

Placenta accreta and balloon catheterization: the experience of a single center and an update of latest evidence of literature.

PURPOSE: We studied the efficacy of using pre-cesarean delivery (CD) temporary occlusion of internal iliac arteries with balloon catheters in case of placenta previa-accreta in terms of maternal and neonatal outcomes and to test accuracy of ultrasound (US) and magnetic resonance imaging (MRI) for prenatal diagnosis. METHODS: From March 2014 to January 2018, women with an US and/or MRI diagnosis of placenta previa-accreta and a planned delivery were enrolled and divided into two groups: balloon catheterization group (women treated with preoperative catheters and CD) and control group (women candidates to elective CD). RESULTS: 37 patients were enrolled: 16 in balloon catheterization group and 21 in control group. Significant differences were detected in estimated blood loss. Prophylactic balloon catheterization could reduce intraoperative red blood cell transfusion. The incidence of hysterectomy was lower in balloon group. No statistical difference was found for neonatal outcomes. Both US and MRI have showed to be useful and complementary to diagnose placenta previa-accreta. CONCLUSIONS: Temporal, perioperative, and prophylactic positioning of balloon vascular catheters is an effective method for managing severe hemorrhage caused by placenta previa-accreta as it reduced intraoperative blood loss, lessened perioperative hemostatic measures and intraoperative red cell transfusions, and reduced hysterectomies.

OAS Gene Family Expression Is Associated with HIV-Related Neurocognitive Disorders.

HIV-associated neurocognitive disorders are common in HIV-infected individuals, even in the combination antiretroviral therapy (c-ART) era. Several mechanisms are involved in neuronal damage, including chronic inflammation immune activation. Mammalian 2'-5'-oligoadenylate synthetase (OAS) genes are produced in response to interferon (IFN), mainly by monocytes, and exert their antiviral functions by activation of RNase L that degrades viral and cellular RNAs. In this study, we aimed at exploring OAS gene family RNA expression in simian immunodeficiency virus encephalitis (SIVE), in HIV-associated neurocognitive disorders (HAND), and in HIV-associate dementia (HAD). We analyzed three microarray datasets obtained from the NCBI in order to assess the expression levels of OAS gene family network in brain biopsies of macaques with SIVE vs uninfected animals, as well as post-mortem brain of individuals with HAND (on or off ART) vs uninfected controls and three brain regions of HIV-infected individuals with both neurocognitive impairment (HAD) and encephalitis (HIVE). All OAS genes were upregulated both in SIVE and in HAND. OAS expression was significantly higher in high-viremic individuals; increased expression levels persisted in cART subjects when compared to healthy controls. OAS gene network analysis showed that several genes belonging to the type I IFN pathway, especially CXCL10 and IFIT3, were similarly upregulated in SIVE/HAND. Furthermore, we identified a significant upregulation of OAS gene family RNA expression in basal ganglia, white matter, and frontal cortex of HIV-1, HAD, and HAD/HIVE patients compared to healthy subjects. OAS gene family expression is increased in brain sections from individuals with HAND, HAD, and HIVE as well as macaques with SIVE. OAS family expression is likely to be induced by IFN as a consequence of viral replication in the CNS. Its long-term upregulation may contribute to the chronic inflammatory status and neurocognitive impairment we still observe in virologically suppressed individuals on c-ART.

Effects of myo-inositol, gymnemic acid, and L-methylfolate in polycystic ovary syndrome patients.

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine and metabolic disorder, characterized by chronic anovulation/oligomenorrhea, hyperandrogenism, and insulin-resistance. Moreover, some studies propose a possible association between insulin resistance and hyperhomocysteinemia, which is a significant long-term risk for factor for atherogenesis and chronic vascular damage, especially in situations where insulin levels are increased. Insulin-sensitizing agents are used in the treatment of PCOS: in fact, inositols were shown to have insulin-mimetic properties. Synergic action to myo-inositol is that of gymnemic acids that have antidiabetic, anti-sweetener, and anti-inflammatory activities. Gymnemic acid formulations have also been found useful against obesity due to their ability to delay the glucose absorption in the blood. L-methyl-folate increases peripheral sensitivity to insulin, maintaining folatemia stable, and thus restoring normal homocysteine levels. Unlike folic acid, L-methyl folate has a higher bioavailability, no drug/food interferences, high absorption, and it is stable to UV-A exposure. The aim of our study is to compare the clinical, endocrine, and metabolic parameters in 100 PCOS women treated with myo-inositol, gymnemic acid, and l-methylfolate (Group A) or myo inositol and folic acid only (Group B), continuously for 6 months. From a clinical point of view, it was noticed a more significant improvement of the menstrual cycle regularity and a more significant reduction of BMI in Group A. Moreover, a more significant decrease of total testosterone and increase of SHBG serum levels were noticed in Group A. The metabolic assessment found a more significant decrease of total cholesterol and homocysteine levels; OGTT glycemia and insulinemia values were significantly more improved after treatment with myo-inositol + gymnemic acid. In conclusion, we can state that a good option for the treatment of PCOS is the combined administration of myo-inositol + gymnemic acid + l-methyl-folate, especially for overweight/obese patients with marked insulin resistance and with associated hyperhomocysteinemia.
