Advances in cancer immunotherapy have offered new hope for patients with metastatic disease. This unfolding success story has been exemplified by a growing arsenal of novel immunotherapeutics, including blocking antibodies targeting immune checkpoint pathways, cancer vaccines, and adoptive cell therapy (ACT). Nonetheless, clinical benefit remains highly variable and patient-specific, in part, because all immunotherapeutic regimens vitally hinge on the capacity of endogenous and/or adoptively transferred T-effector (Teff) cells, including chimeric antigen receptor (CAR) T cells, to home efficiently into tumor target tissue...

While many pharmacologic therapies for the treatment of idiopathic pulmonary fibrosis (IPF) have been evaluated via randomized, placebo-controlled clinical trials (RCTs) conducted over the past two decades, most therapies have been shown to be ineffective or even potentially harmful. However, a number of recently completed RCTs have shown significant efficacy for pirfenidone and nintedanib for the treatment of IPF. Areas Covered: This manuscript reviews recent advances in the management of IPF and other forms of fibrosing interstitial lung disease (ILD) with an emphasis on IPF...

BACKGROUND: Despite considerable efforts made in recent years, the industrial accident rate and the fatality rate in the Republic of Korea are much higher than those in most developed countries in Europe and North America. Industrial safety policies and safety regulations are also known to be ineffective and inefficient in some cases. METHODS: This study focuses on the quantitative evaluation of the effectiveness of direct safety regulations such as safety certification, self-declaration of conformity, and safety inspection of industrial machines in the Republic of Korea...

As the obesity epidemic worsens, the prevalence of maternal obesity is expected to rise. Both high-fat and high-sucrose diets are known to promote maternal obesity and several studies have elucidated the molecular influence of high-fat feeding on female reproduction. However, to date, the molecular impact of a high-sucrose diet on maternal obesity remains to be investigated. Using our previously reported Drosophila high-sucrose maternal obesity model, we sought to determine how excess dietary sucrose impacted the ovary...

Purpose: Lapatinib is a candidate drug for treatment of trastuzumab-resistant, HER2-positive gastric cancer (GC). Unfortunately, lapatinib resistance renders this drug ineffective. The present study investigated the implication of forkhead box protein O1 (FOXO1) signaling in the acquired lapatinib resistance in HER2-positive GC cells. Materials and Methods: Lapatinib-resistant GC cell lines (SNU-216 LR2-8) were generated in vitro by chronic exposure of lapatinib-sensitive, HER2-positive SNU-216 cells to lapatinib...

BACKGROUND/AIMS: Ineffective esophageal motility (IEM) is the most common gastrointestinal motility disorder. Studies have reported that IEM is related to gastroesophageal reflux disease (GERD). However, the relationship between IEM and GERD remains uncertain. This study aims to clarify this relationship retrospectively. METHODS: We analyzed 195 subjects who underwent high-resolution manometry between January 2011 and September 2016. Of these subjects, 72 had normal esophageal motility (NEM) and 26 had IEM...

The odd-even car trial scheme, which reduced car traffic between 08.00 and 20.00 h daily, was applied from 1 to 15 January 2016 (winter scheme, WS) and 15-30 April 2016 (summer scheme, SS). The daily average PM2.5 and PM10 exceeded national standards, with highest concentrations (313 μg m(-3) and 639 μg m(-3), respectively) during winter and lowest (53 μg m(-3) and 130 μg m(-3)) during the monsoon (June-August). PM concentrations during the trials can be interpreted either as reduced or increased, depending on the periods used for comparison purposes...

AIM: Valproic acid (VPA) is used in epilepsy treatment and as a stabilizer in bipolar affective disorder for over 40 years. Although, the pharmacokinetic properties of valproic acid are well known, it is often forgotten that the formulation of the drug significantly influences its gastrointestinal absorption. CASE: We are describing the case of 30 year-old female patient, diagnosed at the age of 13 with juvenile myoclonic epilepsy. Complete ineffectiveness of the treatment was caused by malabsorption of sodium valproate and valproic acid in the patient...

Muscle weakness is a hallmark of severe vitamin D deficiency, but the effect of milder vitamin D deficiency or insufficiency on muscle mass and performance and risk of falling is uncertain. In this presentation, I review the evidence that vitamin D influences muscle mass and performance, balance, and risk of falling in older adults. Special consideration is given to the impact of both the starting 25-hydroxyvitamin D [25(OH)D] level and the dose administered on the clinical response to supplemental vitamin D in older men and women...

Musa Al-Zahrani, Kerry J Savage
Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), corresponds with a heterogeneous group of mature T-cell lymphomas. Recent gene expression profiling studies have identified at least two molecular subgroups (GATA3 and TBX2). Standard treatment and outcomes remain poor. High-dose chemotherapy with autologous stem cell transplantation is incorporated into primary therapy for young fit patients but remains ineffective for most and has not been tested in a randomized study. Several novel agents have been approved for use in relapsed/refractory PTCLs, and although response rates are modest for most, durable remissions have been reported...

Many countries use health warnings in an attempt to regulate alcohol consumption. However, there is a lack of conclusive evidence in the research on alcohol warnings to support decision-making on effective health policies. This study explores the effectiveness of two mandatory warnings introduced in France in 1991 and 2007: the first (Alcohol abuse is harmful) is displayed on alcohol advertisements; the second (a pictogram) on bottles. Given that advertising content regulations have been implemented in some countries to reduce the attractiveness of alcohol marketing (e...

Cardiac disease is the leading cause of death in the developed world. Ventricular arrhythmias associated with myocardial ischaemia and/or infarction are a major contributor to cardiovascular mortality, and require improved prevention and treatment. Drugs, devices, and radiofrequency catheter ablation have made important inroads, but have significant limitations ranging from incomplete success to undesired toxicities and major side effects. These limitations derive from the nature of the intervention. Drugs are frequently ineffective, target the entire heart, and often do not deal with the specific arrhythmia trigger or substrate...

Introduction.:  Laxatives are commonly used to treat opioid-induced constipation, the commonest and most bothersome complication of opioids. However, laxatives have a nonspecific action and do not target underlying mechanisms of opioid-induced constipation; their use is associated with abdominal symptoms that negatively impact quality of life. Objective.:  To assess the effects of laxatives in patients taking opioids for chronic pain. Methods...

Intracranial hypotension syndrome (IHS) is generally caused by cerebrospinal fluid (CSF) leakage. Complications include bilateral subdural hygroma or haematoma and herniation of the cerebellar tonsils. Epidural blood patch (EBP) therapy is indicated if conservative treatment is ineffective. We reported the case of a 46-year-old man with a history of postural headache and dizziness. The patient was treated with bed rest and daily hydration with 2000 mL of fluid for 2 weeks. However, dizziness and headache did not resolve, and he became drowsy and disoriented with incomprehensible speech...

AIM: The challenge in treating neurological diseases is not lack of drug potency, but ineffective targeting techniques. We propose a technique called intrathecal magnetic drug targeting (IT-MDT), in which intrathecally injected magnetic nanoparticles (MNPs) are targeted to specific sites using external magnets. MATERIALS & METHODS: MRI and histology confirmed localization of MNPs via IT-MDT at target sites along the spine of Sprague-Dawley rats. RESULTS: MRI results confirmed greater MNP localization when the duration of magnet application was extended...

Spine procedures are associated with high rates of blood loss which can result in a greater need for transfusions. Repeated exposure to blood products is associated with risks and adverse reactions such as transfusion-related acute lung injury, fluid shifting, and infections. With the higher number of spine procedures and the increasing open surgery times associated with difficult procedures, excessive blood loss has become more prevalent. Perioperative methods have been established to combat the excessive blood loss and decrease the need for blood products...

Clinical applications of current photodynamic therapy (PDT) photosensitizers (PSs) are often limited by their absorption in the UV-vis range that possesses limited tissue penetration ability, leading to ineffective therapeutic response for deep-seated tumors. Alternatively, two-photon excited PS (TPE-PS) using NIR light triggered is one the most promising candidates for PDT improvement. Herein, multimodal polymer nanoparticles (PNPs) from polythiophene derivative as two-photon fluorescence imaging as well as two-photon-excited PDT agent are developed...

Treatment options for gestational diabetes (GDM) are limited. In order to better understand mechanisms and improve treatments, appropriate animal models of GDM are crucial. Heterozygous db mice (db/+) present with glucose intolerance, insulin resistance, and increased weight gain during, but not prior to, pregnancy. This makes them an ideal model for GDM. However, several recent studies have reported an absence of GDM phenotype in their colony. We investigated several hypotheses for why the phenotype may be absent, with the aim of re-establishing it and preventing further resources being wasted on an ineffective model...

REVIEW
Darren M Brenner, Emily Stern, Brooks D Cash
PURPOSE OF REVIEW: Opioids are a mainstay in the treatment of chronic non-cancer pain syndromes, but their analgesic benefits come at a cost as opioid-related constipation occurs in 40-80% of individuals taking chronic opioids. Furthermore, as 10-20% of the population suffers from constipation at baseline, it should be expected that while a proportion of individuals will develop constipation as a direct consequence of opioids (OIC), others will experience it as an exacerbation of their baseline constipation (OEC)...
