Published: October 2019

Objectives: First, this research was instituted to identify common allergens, and second, to test the association between IL16 gene promoter polymorphism rs4778889 T/C and allergic contact dermatitis (ACD). Methods: A case control study was conducted in dermatology outpatients’ clinic. Study subjects received interview-based semi-structured questionnaire, complete skin examination, IL16 gene promoter was investigated by PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis, and IQ Ultra™ patch test units (Chemotechnique Diagnostics AB, Sweden) with 10 substances were used. Results: Most of the prevalent cases had positive patch test (93.3%). The most common clinical presentation of ACD in our patients was itching (96.7%), followed by dryness (86.75%), erythema (76.7%), and fissuring (76.7%). There was higher CC gene distribution among cases, but there was no statistically significant difference. IL16 gene distribution was nearly similar among different clinical presentations. Formaldehyde showed statistically significant higher frequency for CC. The most common allergen found was mercury chloride (76.6%), followed by potassium dichromate (26.6%) and cobalt chloride (20%). Conclusions: The current study found prominent metal sensitization (mercury chloride) over the previously known potassium dichromate. There was no statistically significant IL16 gene distribution among cases compared with control. However, C allele was more frequently encountered in cases. Further studies are required to test the association with IL16 genotype and ACD and highlight the new trends in metal sensitization among cement-exposed workers.
Lung transplantation: a review of the optimal strategies for referral and patient selection
Authors: Mitchell Alicia B. , Glanville Allan R. 
Published: October 2019

One of the great challenges of lung transplantation is to bridge the dichotomy between supply and demand of donor organs so that the maximum number of potential recipients achieve a meaningful benefit in improvements in survival and quality of life. To achieve this laudable goal is predicated on choosing candidates who are sufficiently unwell, in fact possessing a terminal respiratory illness, but otherwise fit and able to undergo major surgery and a prolonged recuperation and rehabilitation stage combined with ongoing adherence to complex medical therapies. The choice of potential candidate and the timing of that referral is at times perhaps more art than science, but there are a number of solid guidelines for specific illnesses to assist the interested clinician. In this regard, the relationship between the referring clinician and the lung transplant unit is a critical one. It is an ongoing and dynamic process of education and two way communication, which is a marker of the professionalism of a highly performing unit. Lung transplantation is ultimately a team effort where the recipient is the key player. That principle has been enshrined in the three consensus position statements regarding selection criteria for lung and heart-lung transplantation promulgated by the International Society for Heart and Lung Transplantation over the last two decades. During this period, the number of indications for lung transplantation have broadened and the number of contraindications reduced. Risk management is paramount in the pre- and perioperative period to effect early successful outcomes. While it is not the province of this review to reiterate the detailed listing of those factors, an overview position will be developed that describes the rationale and evidence for selected criteria where that exists. Importantly, the authors will attempt to provide an historical and experiential basis for making these important and life-determining decisions.

Published: October 2019

Abstract
Cancer and cardiovascular diseases are the leading causes of death in high-income countries. Cardiovascular complications can be found in cancer patients, being the result of so-called ‘cardio-toxicity’. Therefore, it becomes essential to thoroughly investigate the origin of cardiac damage and the strategy to prevent it or to reverse the negative remodelling associated with cardiotoxicity. In this review the beneficial effects of physical exercise in cancer patients were analysed, particularly to prevent cardio-toxicity before its clinical manifestation. According to the relevance of exercise, we suggest strategies for exercise prescription with a tailored approach in these patients. In conclusion, physical exercise seems to be a promising and effective treatment for cancer patients during and after therapy and seems to counteract the negative effects induced by drugs on the cardiovascular system. Exercise prescription should be tailored according to patient’s individual characteristics, to the drugs administered, to the personal history, and to his/her response to exercise, taking into account that different types of training can be prescribed according also to the patient’s choice. A cardiological evaluation including exercise testing is essential for an appropriate prescription of exercise in these patients.
Surgical Technique and Clinical Outcomes of Osteochondral Autograft Transplantation for Large Osteonecrotic Lesions of the Femoral Condyle With Residual Normal Cartilage: The Eyeglass Technique
Authors: Yabumoto Hiromitsu , Nakagawa Yasuaki , Mukai Shogo 
Published: October 2019

Background: Osteochondral autograft transplantation (OAT) is usually performed for a defect that is <400 mm2 because of the limitations of autografts. Purpose: To present the surgical technique and clinical outcomes of OAT using the eyeglass technique for large osteonecrotic lesions of the femoral condyle (LOFs) (>400 mm2) with residual normal cartilage. Study Design: Cohort study; Level of evidence, 3. Methods: Cases (group 1) included 15 patients (18 knees) who underwent OAT using the eyeglass technique for LOFs with residual normal cartilage, while controls (group 2) included 11 patients (11 knees) who underwent OAT using the standard technique for small osteonecrotic lesions of the femoral condyle (≤400 mm2). Clinical outcomes were evaluated preoperatively and at the final follow-up (group 1, 56 months; group 2, 48 months) according to the International Knee Documentation Committee (IKDC) objective grade, the IKDC subjective score, and the Japanese Orthopaedic Association (JOA) score. Results: The mean lesion size was 685 mm2 in group 1 and 230 mm2 in group 2. Patients in group 1 had postoperative scores equivalent to those in group 2. The postoperative IKDC subjective scores in group 1 (mean, 86.9) and group 2 (mean, 87.0) showed no significant difference at the final follow-up ( P = .653). For postoperative IKDC objective grades, 83.3% of group 1 and 81.8% of group 2 were graded as “nearly normal” or better, and no significant intergroup difference was found for the IKDC objective grade ( P = .989). Also, no significant intergroup difference was found for the postoperative JOA score (group 1, 93.9; group 2, 81.4; P = .480). Nine second-look arthroscopic procedures were performed in group 1 compared with 4 in group 2, and all patients had plugs that were graded as “nearly normal” or better by the International Cartilage Repair Society classification system. Conclusion: The postoperative results of patients who underwent OAT using the eyeglass technique for large osteonecrotic lesions (>400 mm2) were equivalent to the results of patients who underwent OAT using the standard technique for small osteonecrotic lesions (≤400 mm2).

AbstractBackgroundMouse NOTCH1 carries a highly conserved O-fucose glycan at Thr466 in epidermal growth factor-like repeat 12 (EGF12) of the extracellular domain. O-Fucose at this site has been shown by X-ray crystallography to be recognized by both DLL4 and JAG1 Notch ligands. We previously showed that aNotch1Thr466Ala mutant exhibits very little ligand-induced NOTCH1 signaling in a reporter assay, whereas a Thr466Ser mutation enables the transfer of O-fucose and reverts the NOTCH1 signaling defect. We subsequently generated a mutant mouse with the Thr466Ala mutation termedNotch1[12f](Notch1tm2Pst). Surprisingly, homozygousNotch1[12f/12f] mutants on a mixed background were viable and fertile.ResultsWe now report that after backcrossing to C57BL/6 J mice for 11–15 generations, few homozygousNotch1[12f/12f] embryos were born. Timed mating showed that embryonic lethality occurred by embryonic day (E) ~E11.5, somewhat delayed compared to mice lackingNotch1orPofut1(the O-fucosyltransferase that adds O-fucose to Notch receptors), which die at ~E9.5. The phenotype of C57BL/6 JNotch1[12f/12f] embryos was milder than mutants affected by loss of a canonical Notch pathway member, but disorganized vasculogenesis in the yolk sac, delayed somitogenesis and development were characteristic. In situ hybridization of Notch target genesUncx4.1andDll3or western blot analysis of NOTCH1 cleavage did not reveal significant differences at E9.5. However, qRT-PCR of head cDNA showed increased expression ofDll3,Uncx4.1andNotch1in E9.5Notch1[12f/12f] embryos. Sequencing of cDNA fromNotch1[12f/12f] embryo heads and Southern analysis showed that theNotch1[12f] locus was intact following backcrossing. We therefore looked for evidence of modifying gene(s) by crossing C57BL/6 JNotch1[12f/+] mice to 129S2/SvPasCrl mice. Intercrosses of the F1 progeny gave viable F2Notch1[12f/12f] mice.ConclusionWe conclude that the 129S2/SvPasCrl genome contains a dominant modifying gene that rescues the functions of NOTCH1[12f] in signaling. Identification of the modifying gene has the potential to illuminate novel factor(s) that promote Notch signaling when an O-fucose glycan is absent from EGF12 of NOTCH1.
Measurement of leaf lamina moisture with a low-cost electrical humidity sensor: case study on a wheat water-mutant

Published: October 2019

Abstract

Background
The presence and persistence of water on the leaf can affect crop performance and thus might be a relevant trait to select for or against in breeding programmes. Low-cost, rapid and relatively simple methods are of significant importance for screening of large populations of plants for moisture analysis of detached leaves. Leaf moisture can be detected using an electric circuit, where the resistance changes are proportional to the moisture of the measured surface. In this study, we present a protocol to analyse genotypic differences through the electrical properties of living or stored tissues, performed using a commercial device. Expanded and non-expanded leaves were compared to determine the effects of leaf maturity on these data. Two wheat genotypes that differ in tissue affinity for bound water were used to define the influence of water status.

Results
The device indirectly estimates leaf moisture content using two electrodes applied to the leaf lamina of fresh and stored samples. Single moisture readings using this moisture meter had mean execution time of ~ 1.0 min. Exponential associations provided good fits for relationships between the moisture meter reading (MMR) and the electrical resistance applied to the electrodes. MMR normalised for the water/ dry matter ratio (MMRnorm) was lower for mature leaves of the water-mutant than those of wild-type, for the fully hydrated fresh leaves. MMR of fully mature leaves when partially dehydrated and measured after 10 min at 27 °C and 40% relative humidity was greater for the water-mutant than the wild-type.

Conclusions
This case study provides a low-cost tool to compare electrical-resistance estimates of leaf moisture content, together with a promising and rapid phenotyping protocol for genotypic screening of wheat under standard environmental conditions. Measurement of changes in MMR with time, of fresh and partially dehydrated leaves, or of MMR normalised to tissue water content allowed for differentiation between the genotypes. Furthermore, the differences observed between genotypes that here relate particular to tissue affinity for bound water suggest that not only the free-water fraction, but also other water fractions, can affect these electrically estimated leaf moisture measures.
Melatonin alleviates heat-induced damage of tomato seedlings by balancing redox homeostasis and modulating polyamine and nitric oxide biosynthesis

Published: October 2019

Abstract

Background
Melatonin is a pleiotropic signaling molecule that plays multifarious roles in plants stress tolerance. The polyamine (PAs) metabolic pathway has been suggested to eliminate the effects of environmental stresses. However, the underlying mechanism of how melatonin and PAs function together under heat stress largely remains unknown. In this study, we investigated the potential role of melatonin in regulating PAs and nitric oxide (NO) biosynthesis, and counterbalancing oxidative damage induced by heat stress in tomato seedlings.

Results
Heat stress enhanced the overproduction of reactive oxygen species (ROS) and damaged inherent defense system, thus reduced plant growth. However, pretreatment with 100 μM melatonin (7 days) followed by exposure to heat stress (24 h) effectively reduced the oxidative stress by controlling the overaccumulation of superoxide (O2•−) and hydrogen peroxide (H2O2), lowering the lipid peroxidation content (as inferred based on malondialdehyde content) and less membrane injury index (MII). This was associated with increased the enzymatic and non-enzymatic antioxidants activities by regulating their related gene expression and modulating the ascorbate–glutathione cycle. The presence of melatonin induced respiratory burst oxidase (RBOH), heat shock transcription factors A2 (HsfA2), heat shock protein 90 (HSP90), and delta 1-pyrroline-5-carboxylate synthetase (P5CS) gene expression, which helped detoxify excess ROS via the hydrogen peroxide-mediated signaling pathway. In addition, heat stress boosted the endogenous levels of putrescine, spermidine and spermine, and increased the PAs contents, indicating higher metabolic gene expression. Moreover, melatonin-pretreated seedlings had further increased PAs levels and upregulated transcript abundance, which coincided with suppression of catabolic-related genes expression. Under heat stress, exogenous melatonin increased endogenous NO content along with nitrate reductase- and NO synthase-related activities, and expression of their related genes were also elevated.

Conclusions
Melatonin pretreatment positively increased the heat tolerance of tomato seedlings by improving their antioxidant defense mechanism, inducing ascorbate–glutathione cycle, and reprogramming the PAs metabolic and NO biosynthesis pathways. These attributes facilitated the scavenging of excess ROS and increased stability of the cellular membrane, which mitigated heat-induced oxidative stress.

Abstract

Background
Patients receiving maintenance hemodialysis (HD) and peritoneal dialysis (PD) are frequently hospitalized. Reducing unplanned 30-day hospital readmissions is a key priority for improving the quality of health care. The purpose of this study was to assess the association between the Charlson Comorbidity Index (CCI), which has been used to evaluate multi-comorbidities status, and 30-day readmission in patients on HD and PD therapy.

Methods
The Hospital Quality Monitoring System (HQMS), a national administrative database for hospitalized patients in China was used to extract dialysis patients admitted from January 2013 to December 2015. The outcome was the unplanned readmission following the hospital discharge within 30 days. For patients with multiple hospitalizations, a single hospitalization was randomly selected as the index hospitalization. A cause-specific Cox proportional hazard model was utilized to assess the association of CCI with readmission within 30 days.

Results
Of the 124,721 patients included in the study, 19,893 patients (16.0%) were identified as experiencing unplanned readmissions within 30 days. Compared with patients without comorbidity (CCI = 2, scored for dialysis), the risk of 30-day readmission increased with elevated CCI score. The hazards ratio (HR) for those with CCI 3–4, 5–6 and > 6 was 1.01 (95% confidence interval [CI] 0.98–1.05), 1.09 (95% CI 1.05–1.14), and 1.14 (95% CI 1.09–1.20), respectively.

Conclusions
Our study indicated that CCI was independently associated with the risk of 30-day readmission for patients receiving dialysis including HD and PD, and could be used for risk-stratification.

Abstract

Background
Preeclampsia (PE) is a major cause of short and long-term morbidity for affected infants, including consequences of fetal growth restriction and iatrogenic prematurity. In Brazil, this is a special problem as PE accounts for 18% of preterm births (PTB). In the PREPARE (Prematurity REduction by Pre-eclampsia cARE) study, we will test a novel system of integrated care based on risk stratification and knowledge transfer, to safely reduce PTB.

Methods
This is a stepped wedge cluster randomised trial that will include women with suspected or confirmed PE between 20 + 0 and 36 + 6 gestational weeks. All pregnant women presenting with these findings at seven tertiary centres in geographically dispersed sites, throughout Brazil, will be considered eligible and evaluated in terms of risk stratification at admission. At randomly allocated time points, sites will transition to risk stratification performed according to sFlt-1/PlGF (Roche Diagnostics) measurement and fullPIERS score with both results will be revealed to care providers. The healthcare providers of women stratified as low risk for adverse outcomes (sFlt-1/PlGF ≤38 AND fullPIERS< 10% risk) will receive the recommendation to defer delivery. sFlt-1/PlGF will be repeated once and fullPIERS score twice a week. Rates of prematurity due to preeclampsia before and after the intervention will be compared. Additionally, providers will receive an active program of knowledge transfer about WHO recommendations for preeclampsia, including recommendations regarding antenatal corticosteroids for foetal benefits, antihypertensive therapy and magnesium sulphate for seizure prophylaxis. This study will have 90% power to detect a reduction in PTB associated with PE from a population estimate of 1.5 to 1.0%, representing a 33% risk reduction, and 80% power to detect a reduction from 2.0 to 1.5% (25% risk reduction). The necessary number of patients recruited to achieve these results is 750. Adverse events, serious adverse events, both anticipated and unanticipated will be recorded.

Discussion
The PREPARE intervention expects to reduce PTB and improve care of women with PE without significant adverse side effects. If successful, this novel pathway of care is designed for rapid translation to healthcare throughout Brazil and may be transferrable to other low and middle income countries.

Authors: Hesse Michaela , Forstmeier Simon , Cuhls Henning , Radbruch Lukas 
Published: October 2019

Abstract

Background
Increasing the quality of life with short interventions for vulnerable patients is one of the objectives of palliative care. Biographical approaches are used in a range of different interventions which may require considerable resources of staff time and energy. This study evaluated the feasibility of training hospice volunteers in biographical interviews of patients confronted with a life-limiting disease. For the purpose of this study, we evaluated resources such as time needed for training, coordination and supervision, outcome such as completion of the intervention in appropriate time and risks such as causing distress in patients or volunteers as major determinants of feasibility.

Methods
Nine volunteers from a hospice service attended an advanced training with an introduction to palliative care, biography work, interview techniques, transcribing and writing. Volunteers interviewed a patient and developed a written narrative from the interview. Volunteers completed a questionnaire before training and were interviewed at the end of the project. The interviews were audiotaped, transcribed, and evaluated using descriptive and qualitative content analysis.

Results
Patients provided positive feedback from the intervention. Volunteers felt that their involvement was personally rewarding and were moved by the courage and confidence of the patients. There were no systematic problems or negative experiences reported neither by volunteers nor by patients.

Conclusions
We found the use of volunteers for biography work with patients in palliative care feasible and effective in this study. Volunteers needed supervision and ongoing support in providing this intervention.
