Evaluation of the early adverse effects of radiotherapy in breast cancer patients with COVID-19: Prospective single institutional study

The COVID-19 caused by the SARS-CoV-2 coronavirus is at the origin of a global pandemic. This pandemic has prompted the current health system to reorganize and rethink the care offered by health establishments. We report the early toxicity in patients infected with COVID-19 treated at the same time for early-stage breast cancer (BC). This is a monocentric prospective study of patients treated in our hospital between March 2020 and June 2020 and were diagnosed with COVID-19 infection. The inclusion criteria were to be irradiated for early-stage BC and to have a positive COVID-19 diagnosis on a PCR test and/or a lung computed tomography (CT) scan and/or suggestive clinical symptoms. Radiotherapy (RT) consisted of breast or chest wall irradiation with or without lymph node irradiation, with protocols adapted to pandemic situation. The treatment-related toxicity was graded according to the CTCAE (version 4.03). All 350 patients treated for early-stage BC were studied. Of them, 16 were presented with clinical symptoms of COVID-19 infection and of them, 12 had clinical, CT scan, and PCR confirmation. This entire cohort of 12 pts with median age of 56 (42–72) underwent their RT. During the radiotherapy, there were 9 pts presented radiation dermatitis, 8 (66%) were grade 1 and one was (8%) grade 2. Two patients with lymph nodes irradiation presented esophagitis grade 2. This prospective COVID-19 cohort, treated for early-stage BC demonstrated an acceptable toxicity profile with few low-grade adverse events. Longer follow-up is needed to confirm these findings.     

Safety and immunogenicity of adjuvanted recombinant subunit herpes zoster vaccine in lung transplant recipients

Lung transplant recipients are at high risk for herpes zoster and preventive measures are a significant unmet need. We investigated the safety and immunogenicity of two doses of a recombinant zoster vaccine (RZV) in lung transplant recipients (≥50 years). We enrolled 50 patients of which 49 received at least one vaccine dose. Anti-glycoprotein E (gE) antibody levels (n = 43) increased significantly compared to baseline (median optical density [OD] 1.96; interquartile range [IQR]: 1.17–2.89) after the first (median OD 3.41, IQR 2.54–3.81, p < .0001) and second vaccine dose (median OD 3.63, IQR 3.39–3.86, p < .0001). gE-specific polyfunctional CD4+ T cell frequencies (n = 38) also increased from baseline (median 85 per 10⁶ CD4+ T cells; IQR: 46–180) to the first (median 128 per 10⁶ CD4+ T cells; IQR: 82–353; p = .023) and after the second dose (median 361 per 10⁶ CD4+ T cells; IQR: 146–848; p < .0001). Tenderness (83.0%; 95%CI: 69.2–92.4%) and redness (31.9%; 95%CI: 19.1–47.1%) at injection site were common. One rejection episode within 3 weeks of vaccination was observed. This is the first study demonstrating that RZV was safe and elicited significant humoral and cell-mediated immunity in lung transplant recipients. RZV is a new option for the prevention of shingles in this population.     

Assessing and planning home-based care for persons with AIDS

The HIV/AIDS pandemic continues to gather momentum in many developing countries, increasing the already heavy burden on health care facilities. As a result, donors, implementing partners and communities are beginning to create home-based care programmes to provide care for persons with HIV/AIDS. This paper recommends reorienting this home care provision as a service founded in, and coming from, the community rather than the health system. A methodology, in the form of an assessment matrix, is provided to facilitate the assessment of a community's capacity to provide care for people with AIDS. The focus is on rapid assessment methods using, where possible, readily available information to clearly and systematically define current circumstances. The matrix created for a specific community is then used in the development of an action plan with interventions prioritized and tailored to local needs. A case study from a hypothetical developing country, where HIV/AIDS is a significant problem, is used to illustrate the process.     

Surgical repair of abdominal wall]

Surgical repair of abdominal wall defects following tumour resection only raises real problems when the nature of the tumour required wide, or even transfixing excision, as in the case of sarcomas or very advanced carcinomas. Superficial repair is performed according to the algorithm of the simplest technique: secondary healing, partial suture, total suture, transplant, or flap (pedicled or free). In the case of transfixing resection, the combination of a biomaterial for reconstruction of the deep plane and a superficial flap is necessary. For very large transfixing defects of the abdomen, a free flap may be required and, in this case, delayed insertion after initial transfer may further reduce the operative risk ("apple turnover" technique). The complications observed in a detailed series of 9 cases operated at Saint-Louis Hospital consisted of one intraoperative cardio-circulatory arrest during second-stage surgery and one late infection at three years. The authors believe that the indications for delayed insertion of a free flap are still very topical in cases in which a very large grafted free flap is necessary in conjunction with a prosthesis. Large abdominal defects after cancer resection can be reconstructed by modern reconstructive surgery.     

Headache and family history

In two headache questionnaire surveys we inquired about the occurrence of headache in the mothers, fathers, siblings and children of the respondents. In total, 633 people completed valid questionnaires, 260 in the first survey and 373 in the second. The hypothesis was that familial headache occurrence would be positively associated with headache frequency. In each survey, the regression of headache frequency on the number of parents having headache was highly significant. Neither sex nor the sibling and children variables were significant predictors. In the cross-tabulations of the parental occurrence of headache with headache frequency we saw a clear "break-point" between the "no headache" and the headache frequency categories studied. For the final analyses the dichotomy "headache/no headache" was related in fourfold tables to headache occurrence in the father and the mother separately, and to the number of headache parents. The positive associations were not simply due to the large number of migraine cases since they remained after removing the migraineurs.
