67, 95% CI = 0.36, 2.98), but no genotype by treatment effect (P = .80). Among EAs, the placebo group also showed higher rates of opioid-positive UDS than the BUP-XR group (log odds ratio = 1.97, 95% CI = 1.14, 2.79) but a significant genotype by treatment interaction (χ 2(1) = 4.33, P = .04).

We found a moderating effect of rs678849 on the response to buprenorphine treatment of OUD in EAs, but not AAs. These findings require replication in well-powered, prospective studies of both AA and EA OUD patients treated with BUP-XR and stratified on rs678849 genotype.

We reviewed our institutional experience with intravenous thrombolysis (TL) as first-line therapy in patients with Medtronic/HeartWare HVAD left ventricular assist device pump thrombosis (PT).

From March 2006 to November 2018, 30 Medtronic/HeartWare HVAD left ventricular assist device patients had 48 PT events. We analysed outcomes with intravenous Alteplase as a first-line therapy for PT. Pump exchange or urgent heart transplantation was only considered after the failure of TL or existing contraindications to TL.

TL was used as the first-line therapy in 44 PT events in 28 patients without a contraindication to TL. TL was successful in 61.4% of PT events. More than 1 cycle of TL was necessary in 55.6% of events. The combined success of TL and heart transplantation or device exchange was 81.8%. In 15.9% of events, PT was fatal. Causes of death were severe complications (9.1%) related to TL or discontinuation of therapy for multi-organ failure (6.8%). Intracranial bleeding and arterial thromboembolism were observed in 4.5% and 11.5% of the PT events after TL.

Intravenous TL as a first-line therapy for PT in Medtronic/HeartWare HVAD patients can be a reasonable treatment option and does not preclude subsequent heart transplantation or device exchange. However, thromboembolic and bleeding complications are common. The decision to perform TL or device exchange should, therefore, be made on an individual basis after balancing the risks and benefits of different treatment approaches.

There is an ongoing controversy about harms and benefits of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) in hypertensive patients with coronavirus disease 2019 (COVID-19). Given the unresolved debate, we investigated the association of ARBs with in-hospital outcomes of these patients.

In this retrospective observational study, we studied patients with COVID-19 who referred to Sina Hospital in Tehran, Iran, from 20 February to 29 May 2020. Patients with either positive real-time reverse-transcriptase polymerase-chain-reaction test of swab specimens, or high clinical suspicion according to the World Health Organization's interim guidance were included. We followed-up patients for incurring death, severe COVID-19, and in-hospital complications.

We evaluated 681 patients with COVID-19 of whom 37 patients were excluded due to incomplete medical records and 8 patients who used ACEIs which left 636 patients in the analysis. In this cohort, 108 (17.0%) patients expired and 407 (64.0%) patients incurred severe COVID-19. Of 254 (39.9%) patients with hypertension, 122 (48.0%) patients were receiving an ARB. After adjustment for possible confounders, we found no independent association between taking ARBs and in-hospital outcomes except for acute kidney injury (AKI), in patients with confirmed or clinically suspected COVID-19, either hypertensive or not-hypertensive. We found that discontinuation of ARBs during hospitalization was associated with a greater risk of mortality, invasive ventilation, and AKI (all P ˂ 0.002).

We found that taking ARBs by patients with hypertension and confirmed or clinically suspected COVID-19 is not associated with poorer in-hospital outcomes after adjustment for possible confounders.

Ulcerative colitis (UC) patients have a greater risk of developing colorectal cancer through inflammation-dysplasia-carcinoma sequence of transformation. The histopathological diagnosis of dysplasia is therefore of critical clinical relevance, but dysplasia may be difficult to distinguish from inflammatory changes.

A proteomic pilot study on 5 UC colorectal dysplastic patients highlighted proteins differentially distributed between paired dysplastic, inflammatory and normal tissues. The best candidate marker was selected and immunohistochemistry confirmation was performed on AOM/DSS mouse model lesions, 37 UC dysplasia, 14 UC cancers, 23 longstanding UC, 35 sporadic conventional adenomas, 57 sporadic serrated lesions and 82 sporadic colorectal cancers.

Differential proteomics found 11 proteins significantly more abundant in dysplasia compared to inflammation, including Solute carrier family 12 member 2 (SLC12A2) which was confidently identified with 8 specific peptides and was below the limit of quantitation in both inflammatory and normal colon. SLC12A2 immunohistochemical analysis confirmed the discrimination of preneoplastic and neoplastic lesions from inflammatory lesions in mice, UC and in sporadic contexts. A specific SLC12A2 staining pattern termed "loss of gradient" reached 89% sensitivity, 95% specificity and 92% accuracy for UC-dysplasia diagnosis together with an inter-observer agreement of 95.24% (multirater κfree of 0.90; IC95% 0.78 - 1.00). Such discrimination could not be obtained by Ki67 staining. This specific pattern was also associated with sporadic colorectal adenomas and cancers.

We found a specific SLC12A2 immunohistochemical staining pattern in precancerous and cancerous colonic UC-lesions which could be helpful for diagnosing dysplasia and cancer in UC and non-UC patients.

Although instances of negative or hostile ageism have been identified, critical attention to the nuances of ageism throughout the pandemic, such as the prevalence and implications of positive or compassionate ageism, has lagged in comparison. This commentary uses stereotype content theory to extend the conversation regarding COVID-19 and ageism to include compassionate ageism. We offer the "caremongering" movement, a social movement driven by social media to help individuals affected by COVID-19, as a case study example that illustrates how compassionate ageism has manifested during the pandemic. The implications of compassionate ageism that have and continue to occur during the pandemic are discussed using stereotype embodiment theory. Future actions that focus on shifting attention from the intent of ageist actions and beliefs to the outcomes for those experiencing them are needed. Further, seeking older individuals' consent when help is offered, recognizing the diversity of aging experiences, and thinking critically about ageism in its multiple and varied forms are all required.

A live-attenuated Plasmodium falciparum (Pf) sporozoite (SPZ) vaccine (PfSPZ Vaccine) has shown up to 100% protection against controlled human malaria infection (CHMI) using homologous parasites (same Pf strain as in the vaccine). Using a more stringent CHMI, with heterologous parasites (different Pf strain), we assessed the impact of higher PfSPZ doses, a novel multi-dose prime regimen, and a delayed vaccine boost upon vaccine efficacy.

Four groups of 15 healthy, malaria-naïve adults were immunized. Group (Grp) 1 received five doses of 4.5x10 5 PfSPZ (days 1, 3, 5, 7; week 16). Grps 2, 3 and 4 received three doses (weeks 0, 8, 16) with Gp 2 receiving 9.0×10 5/dose, Grp 3 receiving 18.0×10 5/dose, and Grp 4 receiving 27.0×10 5 for dose 1 and 9.0×10 5 for doses 2 and 3. VE was assessed by heterologous CHMI after 12 or 24 weeks. Volunteers not protected at 12 weeks were boosted prior to repeat CHMI at 24 weeks.

At 12-week CHMI, 6/15 (40%) Group 1 (P=0.04), 3/15 (20%) Group 2 vs. 0/8 controls remained aparasitemic. At 24-week CHMI, 3/13 (23%) Group 3, 3/14 (21%) Group 4 vs. 0/8 controls remained aparasitemic (Groups 2-4, VE not significant). Post-boost, 9/14 (64%) vs. 0/8 controls remained aparasitemic (3/6 Group 1, P=0.025; 6/8 Group 2, P=0.002).

Four stacked, priming injections (multi-dose priming) showed 40% VE against heterologous CHMI, while dose escalation of PfSPZ using single dose priming was not significantly protective. Boosting unprotected subjects improved VE at 24 weeks to 64%.

An increasing number of mitral valve operations are performed using minimally invasive procedures. The initiation of a minimally invasive mitral valve surgery programme constitutes a unique opportunity to study outcome differences in patients with similar characteristics operated on through a sternotomy versus a minimally invasive procedure. The goal of this study was to compare short-term outcomes of patients undergoing mitral valve surgery before versus those having surgery after the introduction of a minimally invasive programme.

The single-centre study included mitral valve procedures performed through a sternotomy or with a minimally invasive approach between January 2012 and May 2019. Propensity score matching was performed to reduce selection bias.

A total of 605 patients (294 sternotomy, 311 minimally invasive) who underwent mitral valve surgery were included in the analysis. Propensity score matching resulted in 251 matched pairs. In the propensity score-matched analysis, minimally invasive proalve programme with a limited number of surgeons and a well-executed institutional selection strategy did not confer an increased risk for adverse events.

For patients with locally advanced oesophageal cancer, improved complete pathological response after neoadjuvant chemoradiation (nCRT) and the detrimental effects on the quality of life related to oesophagectomy have led to the need for a reliable method to select patients who have achieved complete pathological response and do not need surgery. The reliability of 18F-fluorodeoxyglucose positron emission-computed tomography (PET-CT) for predicting the pathological response after nCRT was evaluated.

Patients with locally advanced oesophageal cancer who were treated with nCRT and oesophagectomy from July 2010 to February 2017 were analysed. On the post-nCRT PET-CT, a complete metabolic response was defined as all tumourous lesions demonstrating maximum standardized uptake value (SUVmax) ≤2.5. To minimize the effect of radiation-induced oesophagitis, complete metabolic response was also defined as no viable lesion distinguishable from the background with diffuse uptake. The sensitivity, specificity, positive predictive value and negative predictive value were analysed for SUVmax, [X]ΔSUVmax and %ΔSUVmax.
