Background: Cervical cancer (CxCa) is mainly a locally invading disease that metastasizes to loco-regional lymph node basins before involving distant organs in more advanced stages. Local immune potentiation of tumor-draining lymph nodes (TDLN) may thus protect against tumor progression. Methods: To identify therapeutic targets for local immune modulation, multi-parameter flow cytometric T-cell profiling of primary cervical tumors (PT) and TDLN (n = 37) was performed. The in-vitro effect of PD-1 blockade on T-cell reactivity to HPV16 E6 oncoproteins was determined in cultures of TDLN and PT single cell suspensions (n = 19). Also, intracellular cytokine staining (ICS) upon anti-CD3 stimulation was performed in metastatic TDLN (LN+) and PT (n = 7), as well as multiplexed immunofluorescence histochemistry staining (n = 8). Results: Our data revealed elevated rates of activated regulatory T cells (aTregs) and of central or effector memory CD8+ T cells in metastatic TDLN (LN+) as compared to tumor-free TDLN (LN-), and equally high or even higher rates of these subsets in PT. Both memory subsets co-expressed multiple immune checkpoints. PD-1 blockade significantly enhanced detectable E6-specific T-cell responses in 4/5 HPV16+ LN+ and in 1/5 HPV16+ PT. Whereas aTreg rates were higher in anti-PD-1 non-responders, in responders elevated levels of CD8+FoxP3+CD25+ T cells were observed, which correlated with the efficacy of PD-1 blockade (P = 0.018). This subset was characterized by an early effector memory phenotype with particularly high levels of co-expressed PD-1, CTLA-4, TIM-3 and LAG-3 checkpoints, but, rather than exhausted, was shown upon polyclonal activation to produce higher levels of Granzyme-B and effector cytokines as compared to its CD8+FoxP3- counterparts. Conclusion: These observations support local PD-(L)1 blockade to interrupt loco-regional immune suppression in CxCa and control metastatic spread to TDLN. Furthermore, our data identify CD8+FoxP3+CD25+ T cells as therapeutic targets, which may also serve as predictive biomarker for PD-(L)1 checkpoint blockade. [ABSTRACT FROM AUTHOR]

- Abstract
RNA sequencing (RNA-seq) has become an exemplary technology in modern biology and clinical science. Its immense popularity is due in large part to the continuous efforts of the bioinformatics community to develop accurate and scalable computational tools to analyze the enormous amounts of transcriptomic data that it produces. RNA-seq analysis enables genes and their corresponding transcripts to be probed for a variety of purposes, such as detecting novel exons or whole transcripts, assessing expression of genes and alternative transcripts, and studying alternative splicing structure. It can be a challenge, however, to obtain meaningful biological signals from raw RNA-seq data because of the enormous scale of the data as well as the inherent limitations of different sequencing technologies, such as amplification bias or biases of library preparation . The need to overcome these technical challenges has pushed the rapid development of novel computational tools, which have evolved and diversified in accordance with technological advancements, leading to the current myriad of RNA-seq tools. These tools, combined with the diverse computational skill sets of biomedical researchers, help to unlock the full potential of RNA-seq. The purpose of this review is to explain basic concepts in the computational analysis of RNA-seq data and define discipline-specific jargon., Competing Interests: ET was employed by the company Pacific Biosciences (United States). The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Deshpande, Chhugani, Chang, Karlsberg, Loeffler, Zhang, Muszyńska, Munteanu, Yang, Rotman, Tao, Balliu, Tseng, Eskin, Zhao, Mohammadi, P.

- Abstract
Purpose: To determine the incidence and clinical predictors of intrathoracic complications in COVID-19 patients, and the association with outcomes., Methods: In this retrospective cross-sectional study, we included 976 patients (age 61 ± 17 years, 62% male) who tested positive for SARS-CoV-2 between March 3-April 4, 2020 and underwent chest imaging. 3836 radiographs from 976 patients and 105 CTs from 88 patients were reviewed for intrathoracic complications, including pneumothorax, pneumomediastinum, pneumopericardium, lobar collapse, pleural effusion, and pneumatocele formation., Results: There was a high rate of intrathoracic complications (197/976, 20%). Pleural effusion was the most common complication (168/976, 17%). Pneumothorax (30/976, 3%) and pneumatoceles (9/88, 10%) were also frequent. History of hypertension and high initial CXR severity score were independent risk factors for complications. Patients with any intrathoracic complication during admission had an over 11-fold risk of ICU admission (adjusted odds ratio [aOR] 11.2, p < 0.0001) and intubation (aOR 12.4, p < 0.0001), over 50% reduction in successful extubation (aOR 0.49, p = 0.02) and longer length of stay (median 13 versus 5 days, p < 0.0001). There was no difference in overall survival between patients with and without any complication (log-rank p = 0.94)., Conclusion: In COVID-19 patients who underwent chest imaging, 1 in 5 patients have an intrathoracic complication, which are associated with higher level of care and prolonged hospital stay. Hypertension history and high CXR severity score confer an increased risk of complication., Summary: Intrathoracic complications in COVID-19 are common and are predictive of ICU admission, need for intubation, less successful extubation, and longer length of stay but are not predictive of mortality., (Copyright © 2022 Elsevier Inc.

- Abstract
Human papillomavirus (HPV) infection drives tumorigenesis in almost all cervical cancers and a fraction of vulvar and penile cancers. Due to increasing incidence and low vaccination rates, many will still have to face HPV-related morbidity and mortality in the upcoming years. Current treatment options (i.e., surgery and/or chemoradiation) for urogenital (pre-)malignancies can have profound psychosocial and psychosexual effects on patients. Moreover, in the setting of advanced disease, responses to current therapies remain poor and nondurable, highlighting the unmet need for novel therapies that prevent recurrent disease and improve clinical outcome. Immunotherapy can be a useful addition to the current therapeutic strategies in various settings of disease, offering relatively fewer adverse effects and potential improvement in survival. This review discusses immune evasion mechanisms accompanying HPV infection and HPV-related tumorigenesis and summarizes current immunotherapeutic approaches for the treatment of HPV-related (pre-)malignant lesions of the uterine cervix, vulva, and penis.

- Abstract
Background: Therapeutic immune intervention is highly dependent on the T-cell priming and boosting capacity of tumor-draining lymph nodes (TDLN). In vulvar cancer, in-depth studies on the immune status of (pre)metastatic TDLN is lacking., Methods: We have phenotyped and enumerated various T-cell and myeloid subsets in tumor-free (LN-, n=27) and metastatic TDLN (LN+, n=11) using flow cytometry. Additionally, we studied chemokine and cytokine release profiles and assessed expression of indoleamine 2,3-dioxygenase (IDO) in relation to plasmacytoid dendritic cell (pDC) or myeloid subsets., Results: Metastatic involvement of TDLN was accompanied by an inflamed microenvironment with immune suppressive features, marked by hampered activation of migratory DC, increased cytokine/chemokine release, and closely correlated elevations of pDC and LN-resident conventional DC (LNR-cDC) activation state and frequencies, as well as of terminal CD8
+ effector-memory T-cell (TemRA) differentiation, regulatory T-cell (Treg) rates, T-cell activation, and expression of cytotoxic T-lymphocyte protein-4 (CTLA-4) and programmed cell death protein-1 (PD-1) immune checkpoints. In addition, high indoleamine 2,3-dioxygenase (IDO) expression and increased frequencies of monocytic myeloid-derived suppressor cells (mMDSC) were observed. Correlation analyses with primary and metastatic tumor burden suggested respective roles for Tregs and suppression of inducible T cell costimulator (ICOS)+ T helper cells in early metastatic niche formation and for CD14+ LNR-cDC and terminal T-cell differentiation in later stages of metastatic growth., Conclusions: Metastatic spread in vulvar TDLN is marked by an inflamed microenvironment with activated effector T cells, which are likely kept in check by an interplay of suppressive feedback mechanisms. Our data support (neoadjuvant) TDLN-targeted therapeutic interventions based on CTLA-4 and PD-1 blockade, to reinvigorate memory T cells and curb early metastatic spread and growth., Competing Interests: Competing interests: No, there are no competing interests., (© Author(s) (or their employer(s)) 2021.

- Abstract
Aligning sequencing reads onto a reference is an essential step of the majority of genomic analysis pipelines. Computational algorithms for read alignment have evolved in accordance with technological advances, leading to today's diverse array of alignment methods. We provide a systematic survey of algorithmic foundations and methodologies across 107 alignment methods, for both short and long reads. We provide a rigorous experimental evaluation of 11 read aligners to demonstrate the effect of these underlying algorithms on speed and efficiency of read alignment. We discuss how general alignment algorithms have been tailored to the specific needs of various domains in biology., (© 2021. The Author(s).)

- Abstract
Background: Usual vulvar intraepithelial neoplasia (uVIN) is a premalignancy caused by persistent infection with high-risk types of human papillomavirus (HPV), mainly type 16. Even though different treatment modalities are available (eg, surgical excision, laser evaporation or topical application of imiquimod), these treatments can be mutilating, patients often have recurrences and 2%-8% of patients develop vulvar carcinoma. Therefore, immunotherapeutic strategies targeting the pivotal oncogenic HPV proteins E6 and E7 are being explored to repress carcinogenesis., Method: In this phase I/II clinical trial, 14 patients with HPV16+ uVIN were treated with a genetically enhanced DNA vaccine targeting E6 and E7. Safety, clinical responses and immunogenicity were assessed. Patients received four intradermal HPV-16 E6/E7 DNA tattoo vaccinations, with a 2-week interval, alternating between both upper legs. Biopsies of the uVIN lesions were taken at screening and +3 months after last vaccination. Digital photography of the vulva was performed at every check-up until 12 months of follow-up for measurement of the lesions. HPV16-specific T-cell responses were measured in blood over time in ex vivo reactivity assays., Results: Vaccinations were well tolerated, although one grade 3 suspected unexpected serious adverse reaction was observed. Clinical responses were observed in 6/14 (43%) patients, with 2 complete responses and 4 partial responses (PR). 5/14 patients showed HPV-specific T-cell responses in blood, measured in ex vivo reactivity assays. Notably, all five patients with HPV-specific T-cell responses had a clinical response., Conclusions: Our results indicate that HPV-16 E6/E7 DNA tattoo vaccination is a biologically active and safe treatment strategy in patients with uVIN, and suggest that T-cell reactivity against the HPV oncogenes is associated with clinical benefit., Trial Registration Number: NTR4607., Competing Interests: Competing interests: JB is (part time) employee of Modra Pharmaceuticals and stockholder in Modra Pharmaceuticals.

- Abstract
Human papillomavirus (HPV) drives high-grade intraepithelial neoplasia and cancer; for unknown reasons, this occurs most often in the cervical transformation zone. Either mutation or HPV E6-driven inhibition of Notch1 can drive neoplastic development in stratified squamous epithelia. However, the contribution of Notch1 and its Delta-like ligands (DLL) to site susceptibility remains poorly understood. Here, we map DLL1/DLL4 expression in cell populations present in normal cervical biopsies by immunofluorescence. In vitro keratinocyte 2D monolayer models, growth assays, and organotypic raft cultures were used to assess the functional role of DLL-Notch signaling in uninfected cells and its modulation by HPV16 in neoplasia. An RNA sequencing-based gene signature was used to suggest the cell of origin of 279 HPV-positive cervical carcinomas from The Cancer Genome Atlas and to relate this to disease prognosis. Finally, the prognostic impact of DLL4 expression was investigated in three independent cervical cancer patient cohorts. Three molecular cervical carcinoma subtypes were identified, with reserve cell tumors the most common and linked to relatively good prognosis. Reserve cells were characterized as DLL1
- /DLL4+ , a proliferative phenotype that is temporarily observed during squamous metaplasia and wound healing but appears to be sustained by HPV16 E6 in raft models of low-grade and, more prominently, high-grade neoplasia. High expression of DLL4 was associated with an increased likelihood of cervical cancer-associated death and recurrence. Taken together, DLL4-Notch1 signaling reflects a proliferative cellular state transiently present during physiologic processes but inherent to cervical reserve cells, making them strongly resemble neoplastic tissue even before HPV infection has occurred. SIGNIFICANCE: This study investigates cervical cancer cell-of-origin populations and describes a DLL-Notch1 phenotype that is associated with disease prognosis and that might help identify cells that are susceptible to HPV-induced carcinogenesis., (©2021 American Association for Cancer Research.)- Published

- Abstract
PD-1/PD-L1 immune checkpoint inhibitors show potential for cervical cancer treatment. However, low response rates suggest that patient selection based on PD-L1 protein expression is not optimal. Here, we evaluated different PD-L1 detection methods and studied transcriptional regulation of PD-L1/PD-L2 expression by The Cancer Genome Atlas (TCGA) mRNAseq analysis. First, we determined the copy number of the PD-L1/PD-L2 locus by fluorescence in situ hybridization (FISH), PD-L1 mRNA expression by RNA in situ hybridization (RNAish), and PD-L1/PD-L2 protein expression by immunohistochemistry (IHC) on tissue microarrays containing a cohort of 60 patients. Additionally, distribution of PD-L1/PD-L2 was visualized based on flow cytometry analysis of single-cell suspensions (n = 10). PD-L1/PD-L2 locus amplification was rare (2%). PD-L1 mRNA expression in tumor cells was detected in 56% of cases, while 41% expressed PD-L1 protein. Discordant scores for PD-L1 protein expression on tumor cells between cores from one patient were observed in 27% of cases. Interestingly, with RNAish, PD-L1 heterogeneity was observed in only 11% of the cases. PD-L2 protein expression was found in 53%. PD-L1 mRNA and protein expression on tumor cells were strongly correlated (p < 0.001). PD-L1 and PD-L2 protein expression showed no correlation on tumor cells (p = 0.837), but a strong correlation on cells in stromal fields (p < 0.001). Co-expression of PD-L1 and PD-L2 on macrophage-like populations was also observed with flow cytometry analysis. Both PD-L1 and PD-L2 TCGA transcript levels strongly correlated in the TCGA data, and both PD-L1 and PD-L2 strongly correlated with interferon gamma (IFNG) expression/transcript levels (p < 0.0001). Importantly, patients with high PD-L1/PD-L2/IFNG transcript levels had a survival advantage over patients with high PD-L1/PD-L2 and low IFNG expression. Based on these findings, we conclude that PD-L1/PD-L2 expression in cervical cancer is mainly associated with interferon induction and not gene amplification, which makes FISH unsuitable as biomarker. The heterogeneous PD-L1 and PD-L2 expression patterns suggest IHC unreliable for patient selection. RNAish, in conjunction with interferon signaling evaluation, seems a promising technique for immune checkpoint detection. These results warrant further investigation into their prognostic and predictive potential., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 Rotman, Otter, Bleeker, Samuels, Heeren, Roemer, Kenter, Zijlmans, van Trommel, de Gruijl and Jordanova.)

Background: Coronavirus disease 2019 (COVID-19) affects vulnerable populations (VP) adversely., Purpose: To evaluate overall imaging utilization in vulnerable subgroups (elderly, racial/ethnic minorities, socioeconomic status [SES] disadvantage) and determine if a particular subgroup has worse outcomes from COVID-19., Materials/methods: Of 4110 patients who underwent COVID-19 testing from March 3-April 4, 2020 at NewYork-Presbyterian Hospital (NYP) health system, we included 1121 COVID-19 positive adults (mean age 59±18 years, 59% male) from two academic hospitals and evaluated imaging utilization rates and outcomes, including mortality., Results: Of 897 (80%) VP, there were 465 (41%) elderly, 380 (34%) racial/ethnic minorities, and 479 (43%) SES disadvantage patients. Imaging was performed in 88% of patients and mostly portable/bedside studies, with 87% of patients receiving chest radiographs. There were 83% hospital admissions, 25% ICU admissions, 23% intubations, and 13% deaths. Elderly patients had greater imaging utilization, hospitalizations, ICU/intubation requirement, longer hospital stays, and >4-fold increase in mortality compared to non-elderlies (adjusted hazard ratio[aHR] 4.79, p<0.001). Self-reported minorities had fewer ICU admissions (p=0.03) and reduced hazard for mortality (aHR 0.53, p=0.004; complete case analysis: aHR 0.39, p<0.001 excluding "not reported"; sensitivity analysis: aHR 0.61, p=0.005 "not reported" classified as minorities) with similar imaging utilization, compared to non-minorities. SES disadvantage patients had similar imaging utilization and outcomes as compared to their counterparts., Conclusions: In a predominantly hospitalized New York City cohort, elderly patients are at highest mortality risk. Racial/ethnic minorities and SES disadvantage patients fare better or similarly to their counterparts, highlighting the critical role of access to inpatient medical care during the COVID-19 pandemic., Competing Interests: Disclosures: All authors have no disclosures., (2020 by the Radiological Society of North America, Inc.)

- Abstract
Purpose: Adenocarcinoma of the uterine cervix is the second most common type of cervical cancer after squamous cell carcinoma (SCC). Although both subtypes are treated similarly, patients with adenocarcinoma have a worse prognosis. In this study, immunologic features of the tumor microenvironment in these two subsets were pursued with potential therapeutic implications., Experimental Design: The immune microenvironment of primary tumors and nonmetastatic tumor-draining lymph nodes (TDLN) was compared between patients with cervical adenocarcinoma ( n = 16) and SCC ( n = 20) by polychromatic flow cytometry and by transcriptional profiling of the primary tumors ( n = 299) using publicly available data from The Cancer Genome Atlas (TCGA)., Results: Flow cytometric analyses revealed intact T-cell differentiation in TDLNs, but hampered effector T-cell trafficking to the primary tumors in adenocarcinoma, as compared with SCC. TCGA analysis demonstrated higher expression of chemokines involved in effector T-cell homing (CXCL9/10/11) in SCC primary tumors as compared with adenocarcinoma primary tumors, which was highly correlated to a transcriptional signature for type I conventional dendritic cells (cDC1). This was consistent with elevated frequencies of CD141/BDCA3
+ cDC1 in primary tumor SCC samples relative to adenocarcinoma and correspondingly elevated levels of CXCL9 and CXCL10 in 24-hour ex vivo cultures. Hampered cDC1 recruitment in adenocarcinoma was in turn related to lower transcript levels of cDC1-recruiting chemokines and an elevated β-catenin activation score and was associated with poor overall survival., Conclusions: Our data have identified an opportunity for the investigation of potentially novel therapeutic interventions in adenocarcinoma of the cervix, that is, β-catenin inhibition and cDC1 mobilization., (©2020 American Association for Cancer Research.)- Published

- Abstract
Profiling immunoglobulin (Ig) receptor repertoires with specialized assays can be cost-ineffective and time-consuming. Here we report ImReP, a computational method for rapid and accurate profiling of the Ig repertoire, including the complementary-determining region 3 (CDR3), using regular RNA sequencing data such as those from 8,555 samples across 53 tissues types from 544 individuals in the Genotype-Tissue Expression (GTEx v6) project. Using ImReP and GTEx v6 data, we generate a collection of 3.6 million Ig sequences, termed the atlas of immunoglobulin repertoires (TAIR), across a broad range of tissue types that often do not have reported Ig repertoires information. Moreover, the flow of Ig clonotypes and inter-tissue repertoire similarities across immune-related tissues are also evaluated. In summary, TAIR is one of the largest collections of CDR3 sequences and tissue types, and should serve as an important resource for studying immunological diseases.

- Abstract
Aim: To test whether alerting clinicians to severe weight loss in older patients leads to higher dietitian visit rates, to higher body mass index (BMI) levels and, mainly, to lower annual death risk., Methods: The randomized controlled trial included patients aged ≥75 years, with BMI ≤23 kg/m
2 that decreased ≥2 kg/m2 during the previous 2 years. All participants received usual care. Additionally, an email alert was sent only to clinicians of participants assigned to the email alert group. The follow-up period was 12 months., Results: Among 706 participants (mean age 83 ± 6 years; mean baseline BMI 20.5 kg/m2 ), the BMI record was updated in 541 (77%) participants, and 123 participants died. Dietitian visits were reported for 22 patients (6%) in the email group (n = 362) and 14 patients (4%) in the control group (n = 344; OR 1.5, 95% CI 0.8-2.9; P = 0.24). Measured BMI were raised by a mean of 0.69 (95% CI 0.43-0.95) kg/m2 versus 0.79 (95% CI 0.48-1.1) kg/m2 (P = 0.63). A total of 77 patients (21%) died in the intervention group versus 47 (14%) in the control group (P = 0.008; number needed to harm = 13; 95% CI 7-43)., Conclusions: In this trial, alerting clinical staff to severe weight loss in patients aged ≥75 years was not associated with higher visit rates to a dietitian or change in BMI, but was associated with a significantly higher death rate than usual clinical care.

- Abstract
Objectives: The benefit of alerting clinical staff to drug-induced hypocholesterolemia in patients aged 75 years and older remains uncertain., Design, Setting, and Participants: The study included 1791 patients with serum cholesterol <160 mg/dL and on cholesterol-lowering drugs who were assigned to have an e-mail alert sent to their physician, and 1804 patients who were assigned to receive usual clinical care (control group). The primary outcome of the trial was annual death rate. Secondary outcomes included cholesterol-lowering drug dose reduction and emergency department (ED) visits., Results: At 1 year, 58 patients (3.2%) in the intervention group and 61 (3.4%) in the control group had died [relative risk 0.94, 95% confidence interval (CI) 0.66-1.34; P = .74]. Quarter-averaged cholesterol-lowering drug defined daily doses were reduced by -13.5 ± 47.0 (-17% ± 60%) in the intervention group and by -5.1 ± 42.2 (-6%±54%) in the control group (difference -8.5 ± 1.5, 95% CI -5.5 to -11.4; P < .0001). Annual ED visit rates per 1000 patients were 291 in the intervention group and 336 in the control group (45 fewer visits per 1000 patients in the intervention group, 95% CI -1 to -89; P = .04)., Conclusions and Implications: In this trial, alerting clinical staff to hypocholesterolemia in patients aged 75 years and older being treated with cholesterol-lowering drugs was associated with mildly reduced cholesterol-lowering drugs doses and marginally reduced ED visit rates. This e-mail alert intervention was not associated with a significant difference in 1-year survival rate compared with usual clinical care., (Copyright © 2019 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

- Abstract
Objectives: The benefit of alerting clinical staff to low plasma glycated hemoglobin (HbA1c) in patients aged 75 years and older who receive antidiabetic drugs remains uncertain., Design, Setting, and Participants: In a randomized controlled trial, 1684 patients with HbA1c ≤ 6.5% who received antidiabetic drugs were assigned to have an e-mail alert sent to their physician, and 1643 were assigned to have no such alert (control group). The primary outcome of the trial was annual death. Secondary outcomes included antidiabetic drug dose reduction and HbA1c change., Results: In the first quarter, antidiabetic drug-defined daily doses were reduced on average by 10.4 ± 35.8 (16% ± 55%) in the intervention group and by 6.4 ± 36.1 (10% ± 56%) in the control group (difference -4.1 ± 1.2, 95% confidence interval [CI] -6.5 to -1.6; P = .001). Measured HbA1c levels were raised by a mean (± standard deviation) of 0.28 ± 0.77 in the intervention group and by 0.18 ± 0.57 in the control group (difference 0.10 ± 0.02, 95% CI -0.15 to -0.059, P < .001). One year after the alerts, 121 patients (7.2%) died in the intervention group and 107 patients (6.5%) died in the control group (relative risk 1.1, 95% CI 0.86-1.42; P = .44)., Conclusions and Implications: In this trial, alerting clinical staff to low HbA1c in patients aged 75 years and older treated with antidiabetic medicines was associated with mildly reduced antidiabetic doses and increased HbA1c but was not associated with a significant difference in survival rate compared with usual clinical care., (Copyright © 2019 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

- Abstract
Background: In today's world of big data, computational analysis has become a key driver of biomedical research. High-performance computational facilities are capable of processing considerable volumes of data, yet often lack an easy-to-use interface to guide the user in supervising and adjusting bioinformatics analysis via a tablet or smartphone., Results: To address this gap we proposed Telescope, a novel tool that interfaces with high-performance computational clusters to deliver an intuitive user interface for controlling and monitoring bioinformatics analyses in real-time. By leveraging last generation technology now ubiquitous to most researchers (such as smartphones), Telescope delivers a friendly user experience and manages conectivity and encryption under the hood., Conclusions: Telescope helps to mitigate the digital divide between wet and computational laboratories in contemporary biology. By delivering convenience and ease of use through a user experience not relying on expertise with computational clusters, Telescope can help researchers close the feedback loop between bioinformatics and experimental work with minimal impact on the performance of computational tools.

- Abstract
Lymph nodes draining the primary tumor are essential for the initiation of an effective anti-tumor T-cell immune response. However, cancer-derived immune suppressive factors render the tumor-draining lymph nodes (TDLN) immune compromised, enabling tumors to invade and metastasize. Unraveling the different mechanisms underlying this immune escape will inform therapeutic intervention strategies to halt tumor spread in early clinical stages. Here, we review our findings from translational studies in melanoma, breast, and cervical cancer and discuss clinical opportunities for local immune modulation of TDLN in each of these indications.

- Abstract
Juvenile granulosa cell tumor (JGCT) is an extremely rare ovarian tumor that has been associated with Maffucci syndrome. It both secretes hormone and has been postulated to grow in response to hormone. We present a case of a 33-year-old G1P0 asymptomatic woman with a history of Maffucci syndrome found to have a left adnexal mass on routine ultrasonography at 13 weeks gestation. This case demonstrates the sonographic and magnetic resonance imaging (MRI) features of JGCT, as well as the natural progression of the tumor during pregnancy. A follow-up ultrasound 3 weeks after initial diagnosis demonstrated marked growth in size and vascularity of the tumor, prompting unilateral salpingo-oophorectomy. Histopathological findings confirmed the diagnosis of JGCT., (Copyright © 2019 Elsevier Inc. All rights reserved.)

- Abstract
Background: Too-low body mass index (BMI), HbA1c% or cholesterol levels predicts poor survival. This study investigates whether e-mails about these low values, improve health of people older than 75 years., Methods: LIMIT - an open label randomized trial - compares usual care to the addition of an e-mail which alerts the family physicians and nurses to low metabolic indexes of a specific patient and advises on nutritional and medical changes., Participants: Clalit Health Services (CHS) patients in the Northern and Southern Districts, aged ≥75 years with any of the following inclusion criteria: a. Significant weight loss: BMI < 23 kg/m
2 with BMI drop of ≥2 kg/m2 during previous two years and without dietitian counseling during previous year. b. Tight diabetic control: HbA1c% ≤ 6.5% and received anti-diabetic medicines during previous 2 months. c. Drug associated hypocholesterolemia: total cholesterol <160 mg/dL and received cholesterol-lowering medicines during previous 2 months. Excluded from criterion c, were patients diagnosed with either ischemic heart disease, transient ischemic attack or stroke. The primary outcome was death from any cause, within one year. In a population of 48,623 people over the age of 75 years, 8584 (17.7%) patients were identified with low metabolic indices and were randomized to intervention or control groups. E-mails were sent on November 2015 to physicians and nurses at 383 clinics., Discussion: Low metabolic reserve is common in people in Israel's peripheral districts aged ≥75 years.

- Abstract
Background: With the zebrafish increasingly being used in immunology and infectious disease research, there is a need for efficient molecular tools to evaluate immune gene expression in this model species. RT-MLPA (reverse transcription - multiplex ligation-dependent probe amplification) provides a sensitive and reproducible method, in which fluorescently labelled amplification products of unique lengths are produced for a defined set of target transcripts. The method employs oligonucleotide probes that anneal to adjacent sites on a target sequence and are then joined by a heat-stable ligase. Subsequently, multiplex PCR with universal primers gives rise to amplicons that can be analyzed with standard sequencing equipment and relative quantification software. Allowing the simultaneous quantification of around 40 selected markers in a one-tube assay, RT-MLPA is highly useful for high-throughput screening applications., Findings: We employed a dual-colour RT-MLPA probe design for chemical synthesis of probe pairs for 34 genes involved in Toll-like receptor signalling, transcriptional activation of the immune response, cytokine and chemokine production, and antimicrobial defence. In addition, six probe pairs were included for reference genes unaffected by infections in zebrafish. First, we established assay conditions for adult zebrafish infected with different strains of Mycobacterium marinum causing acute and chronic disease. Addition of competitor oligonucleotides was required to achieve peak heights in a similar range for genes with different expression levels. For subsequent analysis of embryonic samples it was necessary to adjust the amounts of competitor oligonucleotides, as the expression levels of several genes differed to a large extent between adult and embryonic tissues. Assay conditions established for one-day-old Salmonella typhimurium-infected embryos could be transferred without further adjustment to five-day-old M. marinum-infected larvae. RT-MLPA results were compared with results of previous transcriptome analyses and with real-time PCR data, demonstrating a good correlation between all expression analysis methods., Conclusions: The RT-MLPA assay developed in this study provides a rapid, cheap, and robust analysis tool for simultaneous quantification of a set of 34 innate immune response genes. With adjustment of conditions, the assay is suitable for infection studies in both adult and embryonic zebrafish. Application of RT-MLPA will facilitate high-throughput screening of immune responses in the zebrafish model.

After they had analysed 50 cases of varicocoele the authors decided to put in writing some of their ideas. They conclude that varicocoele is often sub-clinical, localised to the right side, bilateral only in a number of cases. Although neither the sperm count nor the histology of the testes show specific pathological features, treatment of the condition brings worthwhile rewards. About 40% of patients father pregnancies.

- Abstract
Fourteen tubo-uterin implantations for endometriosis of the horn and infertility have been carried out. They have been made with microsugery with a reversed transcornual T access. The setting of a retractor pushing off the edges of the uterin muscle allows the removing of the pathological zone, allows also not to hurt the vascularisation during the dissection of the nodule, and allows also to suture edge to edge the tube to the uterus under microsurgical control. This original process allows a new setting up of the continuity (Ten permeabilities cheked with hysterography 2 pregnancies and 2 obstructions among 14 cases after a passing of less than 1 year).

- Abstract
The most typical disorder encountered during the menopause is the sudden flush, but the etiopathogenicity of these disorders is still a matter of hypotheses only. Increased levels of FSH and LH have been evoked ; recent cutaneous temperature studies have demonstrated a significant increase in LH but not of FSH, E1, and E2, during sudden flushes. The degree and rapidity of estradiol level variations have also been suggested as relevant factors. Current opinion conduces to be favoured with the involvement of gonadotropins, catecholamines, and indolamines, and perhaps prostaglandins at the hypothalamic level. Whatever the cause may be, vasomotor flushes are present in 55 to 75 % of menopausal women, and may be accompanied with sudoral crises, palpitations, or lipothymia. Women with a harmonious family life are better able to endure these disorders, treatment being most necessary when they result from a greatest disorder. Therapy is essentially estrogen therapy (after exclusion of cancer), progestogens, or veralipride, a non hormonal agent which produces 80 % of positive results, without apparently the disadvantage of estrogen therapy.

- Abstract
We report a histological study of a microsurgical tubo-tubal anastomosis undertaken to restore patency after ligation. It confirms the good level of tissue tolerance of the suture material employed. It emphasizes the difficulty of anastomosis in the ampulloisthmial region because of the discrepancy in size of the parts that have to be brought together. From this we can emphasize the need for carrying out sterilizations only on a limited lenght of the isthmus.
