Alluring optical and electronic properties have made organometallic halide perovskites attractive candidates for optoelectronics. Among all perovskite materials, inorganic CsPbX3 (X is halide) in black cubic phase has triggered enormous attention recently owing to its comparable photovoltaic performance and high stability as compared to organic and hybrid perovskites. However, cubic phase stabilization at room temperature for CsPbI3 still survives as a challenge. Herein we report all inorganic three-dimensional vertical CsPbI3 perovskite nanowires (NWs) synthesized inside anodic alumina membrane (AAM) by chemical vapor deposition (CVD) method...

Zika virus (ZIKV) is a mosquito-borne flavivirus that is the focus of an ongoing pandemic. ZIKV is notable for its severe neurologic sequelae in babies born to infected mothers. High rates of subclinical infection, as evidenced by the finding of ZIKV RNA in asymptomatic donors, raise concerns of risk to the blood supply. To date, a total of four suspected cases of transfusion-transmitted ZIKV have been reported (all in Brazil), none of which were associated with clinical infection in the transfusion recipients...

Sodium-glucose co-transporter 2 (SGLT2) inhibitors are an attractive novel therapeutic option for the treatment of type 2 diabetes. They block the reabsorption of filtered glucose in kidneys, mainly in proximal renal tubules, resulting in increased urinary glucose excretion and correction of the diabetes-related hyperglycemia. Beyond improving glucose control, SGLT2 inhibitors offer potential benefits by reducing body weight and blood pressure. On the basis of the efficacy demonstrated in clinical trials, SGLT2 inhibitors are recommended as second- or third-line agents for the management of patients with type 2 diabetes...

The lack of aroma and natural taste is a critical problem in production and consumption of instant green teas. A method to prepare instant green teas high in-natural-aroma and low-caffeine by the novel column chromatographic extraction with gradient elution is reported. This method simultaneously extracted aroma (or volatile) and non-aroma compounds from green tea. Green tea was loaded into columns with 2.0-fold of petroleum ether (PE): ethanol (8:2). After standing for 3 h until the aroma compounds dissolved, the column was sequentially eluted with 3...

In up to 10% of patients who experience abdominal trauma, renal and urogenital systems will be involved. In polytrauma patients with other potentially life-threatening injuries, renal and genitourinary trauma may be overlooked initially, but a delayed or missed diagnosis of these injuries may result in preventable complications. This review provides a best-practice approach to the diagnosis and management of renal and genitourinary injuries, with an emphasis on the systematic approach needed to identify subtle injuries and avoid long-term urinary sequelae such as hypertension, incontinence, erectile dysfunction, chronic kidney disease, and nephrectomy...

PURPOSE OF REVIEW: Patients with acute life-threatening neuromuscular disease require close cooperation between neuromuscular and intensive care specialists to achieve the best possible outcomes. The problems encountered by these patients are different from those in traditional neuromuscular practice, and neurologists consulting in the ICU need a specific skill set to provide useful guidance. However, outcomes can be very good if treatment is instituted effectively. This review aims to provide an overview of the most important neuromuscular conditions encountered in the ICU and enable a practical approach to patient management...

Men who inherit pathogenic germline mutations in BRCA2 and BRCA1 are at increased risk of developing aggressive prostate cancer, and those with germline mutations in other DNA repair genes such as ATM, CHEK2, and MSH2/MSH6 may also have increased risks. Although clinically important, there is lack of specific guidance regarding management strategies for men at increased risk owing to germline mutation status or family history of aggressive prostate cancer. We review prostate cancer genetic risk factors and the ongoing IMPACT (Identification of Men with a genetic predisposition to ProstAte Cancer: Targeted screening in BRCA1/2 mutation carriers and controls) screening study...

Although non-invasive ventilation (NIV) has been used since the 1960's in the polio epidemic, the development of modern bilevel PAP devices did not become a reality until the 1990's. Over the last 25 years bilevel PAP technology options have exponentially increased. The number of patients receiving this treatment both in the acute setting as well as at home is steadily growing. However, a knowledge gap exists in the way these device settings are adjusted to achieve synchrony and match patient's unique respiratory failure physiology...

BACKGROUND: Health and care technologies often succeed on a small scale but fail to achieve widespread use (scale-up) or become routine practice in other settings (spread). One reason for this is under-theorization of the process of scale-up and spread, for which a potentially fruitful theoretical approach is to consider the adoption and use of technologies as social practices. OBJECTIVE: This study aimed to use an in-depth case study of assisted living to explore the feasibility and usefulness of a social practice approach to explaining the scale-up of an assisted-living technology across a local system of health and social care...

Dolastatin 10, an antineoplastic agent for cancer chemotherapy, is a linear peptide possessing N,N-dimethyl Val-OH, l-valine, (3R,4S,5S)-dolaisoleucine, (2R,3R,4S)-dolaproine and (S)-dolaphenine. Our efficient synthesis includes the following three key features: (1) SmI2-induced cross-coupling was employed to couple aldehyde 11 with (S)-N-tert-butanesulfinyl imine 12 to generate the required stereocenters of Dap (7); (2) asymmetric addition of chiral N-sulfinyl imine 10 provided a straightforward approach to the synthesis of the protected Doe ((S,S)-8); (3) a practical method to the key subunit Val-Dil (24a) has been established as an alternative synthetic route for the synthesis of this challenging chemical structure...

Psychiatric comorbidities are common in movement disorders. This review provides a practical approach to help clinicians to recognize psychiatric disorders in the most frequent movement disorders. However, the extent of neurodegeneration, as well as the impact of medications with considerable CNS effects, influences the diverse psychiatric presentations that, in turn, are influenced by the stress of living with a movement disorder. Depression, anxiety, and psychosis are the most common psychiatric comorbidities in movement disorders and of the medications used to treat the motor disturbances...

For years, hospitals have responded to inefficiencies by adding more resources, whereas research suggests that it is a flow problem. King Faisal Specialist Hospital and Research Center decided to improve efficiency and enhance patient flow through improving patient discharge and reducing length of stay. Eight interventions were implemented; dedicating slots in diagnostic services for discharges, improving communication, eliminating pending exams, identifying discharges the day before, prioritizing laboratory tests, coordinating discharge medication processing and utilizing case management...

IEEE 802.11ah, marketed as Wi-Fi HaLow, extends Wi-Fi to the sub-1 GHz spectrum. Through a number of physical layer (PHY) and media access control (MAC) optimizations, it aims to bring greatly increased range, energy-efficiency, and scalability. This makes 802.11ah the perfect candidate for providing connectivity to Internet of Things (IoT) devices. One of these new features, referred to as the Restricted Access Window (RAW), focuses on improving scalability in highly dense deployments. RAW divides stations into groups and reduces contention and collisions by only allowing channel access to one group at a time...

Alexina J Mason, Manuel Gomes, Richard Grieve, Pinar Ulug, Janet T Powell, James Carpenter
BACKGROUND/AIMS: The analyses of randomised controlled trials with missing data typically assume that, after conditioning on the observed data, the probability of missing data does not depend on the patient's outcome, and so the data are 'missing at random' . This assumption is usually implausible, for example, because patients in relatively poor health may be more likely to drop out. Methodological guidelines recommend that trials require sensitivity analysis, which is best informed by elicited expert opinion, to assess whether conclusions are robust to alternative assumptions about the missing data...

George R Aronoff
Dialysis treatment time, the frequency of dialysis treatments, and the rate of fluid ultrafiltration-each impacts the incidence of intradialytic hypotension. These factors influence blood pressure independently and together. The strongest evidence supports that rapid ultrafiltration increases the likelihood of intradialytic hypotension and that combined strategies leading to a reduction in ultrafiltration rate have the greatest impact on reducing intradialytic hypotension. A practical approach to avoiding the effects of ultrafiltration on systemic hemodynamics would be to set a maximum ultrafiltration rate needed to achieve the desired fluid removal and vary the duration of the treatment to achieve that target volume...

Synthetic photonic lattices provide unique capabilities to realize theoretical concepts emerging in different fields of wave physics via the utilization of powerful photonic technologies. Here we observe experimentally Anderson localization for optical pulses in time domain, using a photonic mesh lattice composed of coupled fiber loops. We introduce a random potential through programmed electro-optic pulse phase modulation, and identify the localization features associated with varying degree of disorder. Furthermore, we present a practical approach to control the band-gap width in photonic lattices by varying the coupling between the fiber loops, and reveal that the strongest degree of localization is limited and increases in lattices with wider band-gaps...

Sleep-disordered breathing (SDB) in adults is a common condition that is associated with a range of medical problems including hypertension, cardiovascular complications, and increase of seizure frequency in susceptible individuals. Polysomnography (PSG) is considered the gold standard measure in the diagnosis of SDB. This is an observational study on the frequency of SDB in adult patients referred for routine EEG. We found that routine EEG was capable of detecting moderate to severe symptoms of SDB in 14% of adult patients (95% confidence interval = 8...
