Abstract
Proteasome inhibitors, immunomodulatory agents and monoclonal antibodies have dramatically changed the natural history of multiple myeloma (MM). However, most patients eventually suffer a relapse and succumb to the disease. Chimeric antigen receptor (CAR) engineered T cells targeting B cell maturation antigen (BCMA), CD138, CS1 glycoprotein antigen (SLAMF7) and light chains are in active development for therapy of refractory /relapsed (RR) MM. CD19- targeted CAR T cells in conjunction with autologous stem cell transplantation also showed activity in RRMM. Dual- target CAR T cells are in clinical trials for RRMM. This review summarized the recent updates of ongoing CAR T clinical trials for multiple myeloma.

Abstract

Background
Breast cancer is the second most prevalent malignancy in Ethiopia and severely affects patients’ health-related quality of life (HRQOL). We aimed to assess HRQoL, factors influencing HRQoL, and utilities among breast cancer patients at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.

Methods
A hospital-based cross-sectional study was conducted in Tikur Anbessa Specialized Hospital from December 2017 to February, 2018. A total of 404 breast cancer patients were interviewed using the validated Amharic version of the European Organization for Research and Treatment of Cancer module (EORTC QLQ-C30), EORTC QLQ-BR23, and Euro Quality of Life Group’s 5-Domain Questionnaires 5 Levels (EQ-5D-5 L) instruments. Mean scores and mean differences of EORTC- QLQ-C30 and EORTC- QLQ-BR23 were calculated. One-way ANOVA test was employed to determine the significance of mean differences among dependent and independent variables while stepwise multivariate logistic regression was used to identify factors associated with the global quality of life (GQOL). Coefficients and level specific utility values obtained from a hybrid regression model for the Ethiopian population were used to compute utility values of each health state. Data was analyzed using SPSS version 23.

Results
The mean age of patients was 43.94 ± 11.72 years. The mean score for GQoL and visual analog scale was 59.32 ± 22.94 and 69.94 ± 20.36, respectively while the mean utility score was 0.8 ± 0.25. Predictors of GQoL were stage of cancer (AOR = 7.94; 95% CI: 1.83–34.54), cognitive functioning (AOR = 2.38; 95% CI: 1.32–4.31), pain (AOR = 7.99; 95% CI: 4.62–13.83), financial difficulties (AOR = 2.60; 95% CI: 1.56–4.35), and future perspective (AOR = 2.08; 95% CI: 1.24–3.49).

Conclusions
The overall GQoL of breast cancer patients was moderate. Targeted approaches to improve patients’ HRQoL should consider stage of cancer, cognitive functioning, pain, financial status and worries about the patient’s future health. This study also provides estimates of EQ-5D utility scores that can be used in economic evaluations.

Authors: Yeşil Yeter , Çelik Mahmut , Yılmaz Bahattin 
Published: November 2019

Abstract

Background
The Yeşilli district (Mardin) is located in the southeastern of Turkey and hosts different cultures. The objective of this study was to record the traditional knowledge of wild edible plants used by indigenous people in Yeşilli, where no ethnobotanical studies have been conducted previously.

Methods
An ethnobotanical study was carried out in Yeşilli district in March 2017–March 2019 to document the traditional knowledge of wild edible plants. The data were collected by interviewing 62 informants. Additionally, the data were analysed based on the cultural importance index (CI) and factor informant consensus (FİC) to determine the cultural significance of wild edible plants and knowledge of wild edible plants among the informants.

Results
We documented 74 wild edible taxa belonging to 31 families and 57 genera in the present study. The richness of the wild edible taxa was highest for vegetables (46 taxa), followed by medicinal plants (17 taxa) and fruit (14 taxa). The most important families were Asteraceae (ten taxa), Rosaceae (seven taxa) and Fabaceae (six taxa). The most culturally important taxa (based on the CI index) were Ficus carica subsp. carica, Lepidium draba, Anchusa strigosa, Rhus coriaria, Glycyrrhiza glabra, Sinapis alba, Gundelia tournefortii, Notobasis syriaca, Onopordum carduchorum, Malva neglecta, Mentha longifolia, Juglans regia and Urtica dioica. The maximum number of use reports was recorded for vegetables (1011). The factor informant consensus index (Fic) varied between 0.95 and 0.98 for preserved vegetables, beverages and spices and processed fruits have the highest Fic (0.99). We reported for the first time the ethnobotanical usage of 12 taxa as food. We also recorded the use of Allium wendelboanum, an endemic species in the study area.

Conclusion
The obtained data were compared with data from other wild edible and ethnobotanical studies conducted in Turkey and particularly those conducted in eastern Turkey. Furthermore, the data were compared with data from studies conducted in the bordering countries of Iraq and Armenia. The present study reflects the cultural diversity of the region, and it is necessary to conduct more studies since it is thought that this diversity will contribute to the economy. This study will enable the traditional use of wild plants as food sources to be passed on to future generations.

Authors: Perez Rivera C. J. , Figueroa-Casanova R. , Ochoa Bonet C. E. , González-Orozco A. 
Published: November 2019

Abstract

Background
Cardiac hemangiomas are rare cardiac neoplasia usually diagnosed in autopsies, from being asymptomatic to debuting with sudden death. The largest hemangioma published in the literature is of 130 mm size, we present the following case of a successful cardiac hemangioma excision of 280 × 35 mm in size, diagnosed due to recurrent cardiac symptoms.

Case presentation
A 48-year-old female patient, Jehovah’s Witness, with no previous diagnoses, is admitted due to recurrent syncopal episodes in the previous months. A transthoracic echocardiogram diagnosed a tumor in the right atrium and inferior vena cava producing a diastolic right ventricular, with preservation of the left ventricular ejection fraction at 55%. Given the high mortality risk, a surgical intervention was performed immediately. Successful excision was completed confirming a 280 × 35 mm mass without any complications, consistent with hemangioma on histopathology. Postoperative recovery showed no recurrence or complications.

Conclusions
Cardiac hemangiomas are rare and its clinical course can be varied from patient to patient. We present excision of a large cardiac mass with a high mortality risk due to its size and the patient’s spiritual beliefs.

Abstract

Background
Insecticides formulated into products that target Anopheles mosquitos have had an immense impact on reducing malaria cases in Africa. However, resistance to currently used insecticides is spreading rapidly and there is an urgent need for alternative public health insecticides. Potential new insecticides must be screened against a range of characterized mosquito strains to identify potential resistance liabilities. The Liverpool School of Tropical Medicine maintains three susceptible and four resistant Anopheles strains that are widely used for screening for new insecticides. The properties of these strains are described in this paper.

Methods
WHO tube susceptibility bioassays were used for colony selection and to screen for resistance to the major classes of public health insecticides. Topical and tarsal contact bioassays were used to produce dose response curves to assess resistance intensity. Bioassays with the synergist piperonyl butoxide were also performed. Taqman™ assays were used to screen for known target site resistance alleles (kdr and ace-1). RT-qPCR was used to quantify expression of genes associated with pyrethroid resistance.

Results
Pyrethroid selection pressure has maintained resistance to this class in all four resistant strains. Some carbamate and organophosphate resistance has been lost through lack of exposure to these insecticide classes. The Anopheles gambiae (sensu lato) strains, VK7 2014, Banfora M and Tiassalé 13 have higher levels of pyrethroid resistance than the An. funestus FUMOZ-R strain. Elevated expression of P450s is found in all four strains and the 1014F kdr mutation is present in all three An. gambiae strains at varying frequencies. Tarsal contact data and overexpression of CYP4G16 and SAP2 suggest penetration barriers and/or sequestration also confer resistance in Banfora M.

Conclusions
Continual selection with deltamethrin has maintained a stable pyrethroid-resistant phenotype over many generations. In conjunction with a standardized rearing regime, this ensures quality control of strains over time allowing for robust product comparison and selection of optimal products for further development. The identification of multiple mechanisms underpinning insecticide resistance highlights the importance of screening new compounds against a range of mosquito strains.

AbstractBackgroundRetinal inflammation affecting the neurovascular unit may play a role in the development of visual deficits following mild traumatic brain injury (mTBI). We have shown that concentrated conditioned media from adipose tissue-derived mesenchymal stem cells (ASC-CCM) can limit retinal damage from blast injury and improve visual function. In this study, we addressed the hypothesis that TNFα-stimulated gene-6 (TSG-6), an anti-inflammatory protein released by mesenchymal cells, mediates the observed therapeutic potential of ASCs via neurovascular modulation.MethodsAbout 12-week-old C57Bl/6 mice were subjected to 50-psi air pulse on the left side of the head overlying the forebrain resulting in an mTBI. Age-matched sham blast mice served as control. About 1 μl of ASC-CCM (siControl-ASC-CCM) or TSG-6 knockdown ASC-CCM (siTSG-6-ASC-CCM) was delivered intravitreally into both eyes. One month following injection, the ocular function was assessed followed by molecular and immunohistological analysis. In vitro, mouse microglial cells were used to evaluate the anti-inflammatory effect of ASC-CCM. Efficacy of ASC-CCM in normalizing retinal vascular permeability was assessed using trans-endothelial resistance (TER) and VE-cadherin expression in the presence of TNFα (1 ng/ml).ResultsWe show that intravitreal injection of ASC-CCM (siControl-ASC-CCM) but not the TSG-6 knockdown ASC-CCM (siTSG-6-ASC-CCM) mitigates the loss of visual acuity and contrast sensitivity, retinal expression of genes associated with microglial and endothelial activation, and retinal GFAP immunoreactivity at 4 weeks after blast injury. In vitro, siControl-ASC-CCM but not the siTSG-6-ASC-CCM not only suppressed microglial activation and STAT3 phosphorylation but also protected against TNFα-induced endothelial permeability as measured by transendothelial electrical resistance and decreased STAT3 phosphorylation.ConclusionsOur findings suggest that ASCs respond to an inflammatory milieu by secreting higher levels of TSG-6 that mediates the resolution of the inflammatory cascade on multiple cell types and correlates with the therapeutic potency of the ASC-CCM. These results expand our understanding of innate mesenchymal cell function and confirm the importance of considering methods to increase the production of key analytes such as TSG-6 if mesenchymal stem cell secretome-derived biologics are to be developed as a treatment solution against the traumatic effects of blast injuries and other neurovascular inflammatory conditions of the retina.
Increased effort during partial ventilatory support is not associated with lung damage in experimental acute lung injury
Authors: Henzler Dietrich , Schmidt Alf , Xu Zhaolin , Ismaiel Nada , Zhang Haibo , Slutsky Arthur S. , Pelosi Paolo 
Published: November 2019

Abstract

Background
An on-going debate exists as to whether partial ventilatory support is lung protective in an acute phase of ARDS. So far, the effects of different respiratory efforts on the development of ventilator-associated lung injury (VALI) have been poorly understood.
To test the hypothesis whether respiratory effort itself promotes VALI, acute lung injury (ALI) was induced in 48 Sprague Dawley rats by hydrochloric acid aspiration model. Hemodynamics, gas-exchange, and respiratory mechanics were measured after 4 h of ventilation in pressure control (PC), assist-control (AC), or pressure support with 100% (PS100), 60% (PS60), or 20% (PS20) of the driving pressure during PC. VALI was assessed by histological analysis and biological markers.

Results
ALI was characterized by a decrease in PaO2/FiO2 from 447 ± 75 to 235 ± 90 mmHg (p < 0.001) and dynamic respiratory compliance from 0.53 ± 0.2 to 0.28 ± 0.1 ml/cmH2O (p < 0.001). There were no differences in hemodynamics or respiratory function among groups at baseline or after 4 h of ventilation. The reduction of mechanical pressure support was associated with a compensatory increase in an inspiratory effort such that peak inspiratory transpulmonary pressures were equal in all groups. The diffuse alveolar damage score showed significant lung injury but was similar among groups. Pro- and anti-inflammatory proteins in the bronchial fluid were comparable among groups.

Conclusions
In experimental ALI in rodents, the respiratory effort was increased by reducing the pressure support during partial ventilatory support. In the presence of a constant peak inspiratory transpulmonary pressure, an increased respiratory effort was not associated with worsening ventilator-associated lung injury measured by histologic score and biologic markers.
Two cases of a perforated duodenal diverticulum after gastrectomy with Roux-en-Y reconstruction

Published: November 2019

Abstract

Background
What type of reconstruction procedure should be applied is one of the important issues in surgery for gastric cancer. We have several options for reconstruction procedure after distal gastrectomy. The Billroth II and Roux-en-Y reconstruction have a duodenal stump while the Billroth I does not have it, which is the biggest structural difference in these procedures. An increase in intraduodenal pressure due to the formation of duodenum stump occasionally causes severe complication such as duodenal stump leakage; however, a duodenal diverticulum perforation after the Roux-en-Y reconstruction has not yet been reported. Herein, we report two cases of a perforated duodenal diverticulum after gastrectomy with the Roux-en-Y reconstruction.

Case presentation
The first case was a 66-year-old man who presented to our hospital with an acute onset right-upper-quadrant abdominal pain. He had undergone laparoscopic distal gastrectomy with the Roux-en-Y reconstruction for the early gastric cancer 15 months before. A large periampullary diverticulum had been detected during the checkup before the gastrectomy. Abdominal contrast-enhanced CT showed a retroperitoneal fluid collection with gas present at the second part of the duodenum. Therefore, a perforated duodenal diverticulum with abdominal abscess was diagnosed, and an emergency laparotomy was performed. Pancreaticoduodenectomy was performed because of severe duodenal inflammation and surrounding tissue damage. The second case was a 52-year-old man who had undergone open distal gastrectomy for locally advanced gastric cancer. Multiple non-ampullary duodenal diverticula had also been identified during the preoperative checkup. On the 2nd postoperative day, he presented with a sudden-onset abdominal pain with peritoneal irritation signs, and intestinal fluid was identified through the intraperitoneal drainage tube placed in a suprapancreatic site during his previous gastrectomy. Therefore, an emergency laparotomy was performed. During laparotomy, a perforated diverticulum at the second part of the duodenum was detected. The perforated duodenum diverticulum was directly sutured with drainage of the retroperitoneal space.

Conclusions
It is necessary to recognize that the Roux-en-Y reconstruction after gastrectomy for gastric cancer patients with duodenal diverticulum might cause a perforation of the diverticulum.

Published: November 2019

AbstractBackgroundVitamin D is a multi-functional fat-soluble metabolite essential for a vast number of physiological processes. Non-classical functions are gaining attention because of the close association of vitamin D deficiency with diabetes, and its complications. The present study was undertaken to evaluate the role of vitamin D as a biomarker for proliferative diabetic retinopathy.MethodsA tertiary care center based cross-sectional study was undertaken. Seventy-two consecutive cases of type 2 diabetes mellitus were included. Diagnosis of diabetes mellitus was made using American Diabetes Association guidelines. Study subjects included: diabetes mellitus with no retinopathy (No DR) (n = 24); non-proliferative diabetic retinopathy (n = 24); and proliferative diabetic retinopathy (n = 24) and healthy controls (n = 24). All of the study subjects underwent complete ophthalmological evaluation. Best Corrected Visual Acuity (BCVA) was measured on the logarithm of the minimum angle of resolution (logMAR) scale. Serum 25-OH Vitamin D assay was done using chemiluminescent microparticle immunoassay technology. Diagnostic accuracy of vitamin D was assessed using receiver operating characteristics curve analysis and area under curve (AUC) was determined for the first time.ResultsANOVA revealed a significant decrease in serum vitamin D levels with severity of diabetic retinopathy (F = 8.95, p < 0.001). LogMAR BCVA was found to increase significantly with the severity of DR (F = 112.64, p < 0.001). On AUC analysis, a cut off value of 18.6 ng/mL for Vitamin D was found to be significantly associated with proliferative diabetic retinopathy [sensitivity = 86.36% (95% CI 65.1–96.9); specificity = 81.82% (95% CI 59.7–94.7); AUC = 0.91 (excellent); and Z value = 8.17].ConclusionsSerum vitamin D levels of ≤ 18.6 ng/mL serve as sensitive and specific indicator for proliferative disease, among patients of DR.

Authors: Lubowiecki-Vikuk Adrian , Król-Zielińska Magdalena , Kantanista Adam 
Published: November 2019

Abstract

Background
The aim of this study was to analyse the use of dietary supplements to support weight reduction (DSSWR) in adults according to sociodemographic background, body mass index (BMI), waist-hip ratio (WHR), body fat percentage (%BF) and level of physical activity (PA).

Method
Participants (n = 1130) were recruited from a region of Poland with a high rate of adult overweight and obesity. Based on anthropometric data, BMI and WHR were calculated. %BF was assessed using a bioimpedance method. To examine the association between DSSWR use and sociodemographic factors, BMI, WHR, %BF and PA multiple logistic regression were conducted.

Results
The rate of DSSWR use in the group studied was high (69.5%). A higher proportion of women, individuals aged 18–35 years, those who had completed higher education, those who did not report financial status as “poor”, with a BMI < 18.5, normal %BF and individuals with a high level of PA used DSSWR. In complete case analysis (n = 1108), primarily financial status reported as “good” (OR = 2.18, 95% CI: 1.69, 2.81) or “hard to say” (OR = 2.41, 95% CI: 1.86, 3.12) (vs. “poor”) and female sex (OR = 2.59, 95% CI: 2.17, 3.08) were associated with DSSWR intake.

Conclusion
It seems that primarily financial status and sex, but also age, education, and level of PA, have significance in DSSWR use in adults and may be considered when developing appropriate strategies for body weight management and health promotion.

Published: November 2019

AbstractBackgroundHeat shock proteins (Hsps) are widely reported in normal cellular dynamics under stress and non-stress conditions, and parallelly, the studies regarding its role in disease condition are also progressing steadily. The function of Hsps in neurodegenerative disorders is puzzling and not fully understood. This review aims to focus on the role of Hsp27 in normal and diseased conditions and emphasize its therapeutic potential.Hsp27Hsp27, in particular, has shown to be involved in cell viability and actin cytoskeleton remodeling and also shown to improve many disease conditions. Phosphorylated Hsp27 modulates the p53 pathway by downregulating cellular senescence and also lowers reactive oxygen species to protect TNFα-mediated apoptosis. Hsp27 is also known to interfere with mitochondria-dependent and mitochondria-independent cell apoptotic stimulation.ConclusionThis article will highlight the various functions of Hsp27 especially as an anti-apoptotic factor and stress response factor and its therapeutic potential in preventing neuronal apoptosis in neurological diseases. This review also includes a comparison of the therapeutic potential of Hsp27 with regard to other small Hsps.
