7% [95% confidence interval 84.7-100] versus 88.4% [82.5-94.3], P=.056; 2-year overall survival 92.7% [84.7-100] versus 93.7% [89.2-98.2], P=.176), but this was restricted to patients below the age of 60years (2-year progression-free survival 100% versus 92.2% [84.8-99.6], P=.031; 2-year overall survival 100% versus 95.9% [90.2-100], P=.075). In peripheral T-cell lymphoma, eight of 11 patients had completely resected disease. In contrast to DLBCL, complete resection was not associated with improved outcome compared to the control.

Young patients with early stage DLBCL may benefit from complete lymphoma resection prior to immunochemotherapy.

IC breaks the analytical process down into stages, separating basic 'description' from more advanced 'interpretation'. This paper focuses on the interpretive analytical stage that is shown to comprise three core processes (i) conceptualising (undertaken inductively, deductively or abductively); (ii) differentiating; and (iii) externalising. Each process is described, followed by published examples to support what has been explained. As qualitative analyses tend to be recursive rather than linear, the three processes often need to be repeated to account for all the data. Following the stages of IC will ensure that qualitative research generates improved understanding of the phenomena being studied, study findings contribute to and enhance the existing literature, the audience for any qualitative output is broad and international, and any practical implications or study recommendations are relevant to other contexts and settings.
To assess whether free PSA ratio (FPSAR) at biochemical recurrence (BCR) can predict metastasis, castrate-resistant prostate cancer (CRPC), and cancer-specific survival (CSS), following therapy for localised disease.

A single-centre retrospective cohort study (NCT03927287) including a discovery cohort composed of patients with an FPSAR after radical prostatectomy (RP) or radiotherapy (RT) between 2000 and 2017. For validation, an independent Biobank cohort of patients with BCR after RP was tested. Using a defined FPSAR cut-off, the metastasis-free-survival (MFS), CRPC-free survival, and CSS were compared. Multivariable Cox models determined the association between post-treatment FPSAR, metastases, and CRPC.

Overall, 822 patients (305 RP- and 363 RT-treated patients and 154 Biobank patients) were analysed. In the RP cohort, a total of 272/305 (89.1%) and 33/305 (10.9%) had a FPSAR test incidentally and reflexively, respectively. In the RT cohort, 155/363 (42.7%) and 208/263 (57.3%) had a FPSAR test incide disease, suggesting a potentially novel role for this biomarker.
Prior literature has suggested synergy between immune checkpoint therapy (ICT) and radiotherapy (RT) for the treatment of brain metastases (BrM), but to the authors' knowledge the optimal timing of therapy to maximize this synergy is unclear.

A total of 199 patients with melanoma and non-small cell lung cancer with BrM received ICT and RT between 2007 and 2016 at the study institution. To reduce selection biases, individual metastases were included only if they were treated with RT within 90 days of ICT. Concurrent treatment was defined as RT delivered on the same day as or in between doses of an ICT course; all other treatment was considered to be nonconcurrent. Multivariable Cox proportional hazards models were used to assess time to response and local disease recurrence on a per-metastasis basis, using a sandwich estimator to account for intrapatient correlation.

The final cohort included 110 patients with 340 BrM, with 102 BrM treated concurrently and 238 BrM treated nonconcurrently. Response rates nconcurrent but delivered within 90 days. Further study of this combination in prospective, randomized trials is warranted.
Tungiasis is a neglected neotropical disease caused by penetration of Tunga spp. into the skin of the host.

Two primates were rescued from nearby different indigenous villages, and the clinical, pathological, and parasitological features of tungiasis were described. Flea identification occurred through their morphometry and was confirmed with the use of a dichotomous key.

Monkey 1 was parasitized by 23 sand fleas and, after treatment, was assigned to the animal rehabilitation center. see more Monkey 2 was in poor body condition and died shortly after clinical examination. At necropsy, this primate was parasitized by 26 specimens of sand fleas.

Both animals altered their tree behavior by staying on the ground for long periods. This parasitic relationship implies the possibility of enlargement of the sand flea dispersion. Thus, this is the first record of Tunga penetrans occurrence in wild Alouatta guariba clamitans.

The treatment of advanced cutaneous head and neck cutaneous squamous cell carcinomas (HNcSCC) results in significant morbidity. Recently, immune checkpoint inhibitor treatment has been approved for DNA mismatch repair (MMR) deficient patients in a histology-agnostic manner. This study aims to evaluate the incidence of MMR deficiency in advanced HNcSCC and its association with clinicopathologic factors.

The cohort included 176 consecutive HNcSCC cases treated with curative intent. Immunohistochemistry for MMR proteins (hMLH1, hMSH2, hMSH6, and hPMS2) was performed. Clinicopathological and survival data was collected prospectively.

The incidence of MMR protein deficiency was 9.1%. There was no association between age, incidence of metachronous malignancies, clinicopathological factors, or survival outcomes.

A higher incidence of MMR deficiency was observed in this cohort of advanced HNcSCC. The lack of association with young age at onset or increased incidence of metachronous malignancies suggests that MMR deficiency is likely to be sporadic in HNcSCC.
