Spontaneously reported persistent symptoms related to coronavirus disease 2019 one year after hospital discharge : A retrospective cohort single-center study.

BACKGROUND: There are no outcome studies for coronavirus disease 2019 (COVID-19) survivors one year after hospital discharge in Germany. METHODS: This retrospective cohort study included all patients with polymerase chain reaction (PCR)-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) hospitalized in the departments of internal medicine of the Klinikum Saarbrücken, a tertiary care hospital, between March 15 and December 31, 2020. A telephone interview with survivors was conducted at least 12 months after discharge. The interview was initiated with an open-ended question whether the patient had fully recovered from the disease. In the event of a subjective incomplete recovery, the patient was prompted to report any continuous or frequent symptoms that had not occurred prior to COVID-19. Finally, independent of the open-ended question response, all patients were asked closed questions which addressed new symptom onset of persistent fatigue, cognitive dysfunction, headache, muscle and joint pain following COVID-19. RESULTS: In all, 235 survivors were contacted and 162 could be included in the analysis. In 55 of 162 interviews (34.0%) at least one persistent COVID-19 symptom (PCS) was spontaneously reported. Four of 55 survivors with PCS reported five additional symptoms on the closed questions. One survivor, who responded positively to the open-ended question, reported new onset PCS in response to the closed questions. Physical fatigue (24.7%), cognitive dysfunction (14.8%), shortness of breath (8.6%), muscle and joint pain (6.8%) and headache (6.2%) were the most frequently reported PCS. CONCLUSIONS: Despite an interview technique aimed to reduce attribution bias by patients, one third of COVID-19 inpatient survivors report PCS one year after hospitalization.

The gagging patient in ORL examinations: predictors, evaluation and treatment.

PURPOSE: Gagging may be a challenge in daily otorhinolaryngology (ORL) routine. This cross-sectional study aimed to examine conditions of gagging as limitation to ORL examination and the efficacy of acupressure as tool to reduce exaggerated gagging. METHODS: The study was conducted on a total of 360 study subjects. There was a survey part and a routine ORL examination with observation of gagging behaviour. Through binomial univariate logistic regression, predictors of clinically relevant exaggerated gagging were identified. Wilcoxon signed rank test was used to evaluate efficacy of acupressure point CV-24 to reduce gagging while examination. RESULTS: First gagging's relevance was indicated by over 40% of study subjects showing clinically relevant exaggerated gagging. Furthermore, we found that more psychogenic than somatogenic features proved to be predictors of exaggerated gagging. Third acupressure point CV-24 showed statistical significant reduction of gagging intensity and improved examination feasibility. CONCLUSION: Awareness of exaggerated gagging's predictors are the first step to deal with gagging in daily practice. Acupressure might be an effective tool to overcome gagging in the affected patients. LEVEL OF EVIDENCE: We suggest at least Level IV according to Oxford (UK) CEBM Levels of Evidence.

Vitamin D deficiency in head and neck cancer patients - prevalence, prognostic value and impact on immune function.

Vitamin D deficiency is frequently observed in human cancer patients and a prognostic relevance could be shown for some entities. Additionally, it is known that vitamin D can stimulate the patients' antitumor immunity. However, valid epidemiological data for head and neck squamous cell carcinoma (HNSCC) patients are sparse and functional studies on a possible connection between vitamin D and the patients' immune system are missing. 25-OH vitamin D serum levels were analyzed in 231 HNSCC patients and 232 healthy controls and correlated with clinical data and patient survival. Intra- and peritumoral infiltration with T-cell, NK-cell and macrophage populations was analyzed in 102 HNSCC patients by immunohistochemistry. In 11 HNSCC patients, NK-cells were isolated before and after vitamin D substitution and analyzed for their cytotoxic activity directed against a HNSCC cell line. Vitamin D serum levels were significantly lower in HNSCC patients compared with healthy controls. Low vitamin D levels were associated with lymphatic metastasis and a negative HPV status and were a significant predictor of poor overall survival. HNSCC patients with severe vitamin D deficiency showed significantly altered intra- and peritumoral immune cell infiltrate levels. After vitamin D substitution, the patients' NK cells showed a significant rise in cytotoxic activity. Taken together, we could show that Vitamin D deficiency is highly prevalent in HNSCC patients and is a predictor of poor survival. Vitamin D substitution used as an adjuvant in immune therapies such as cetuximab and nivolumab treatment could support antitumorigenic immune responses, thus contributing to the improvement of the patients' prognosis in the context of a multimodal therapy.
