Immune correlates of protection by vaccine against SARS-CoV-2 in patients with chronic lymphocytic leukaemia.

In chronic lymphocytic leukaemia (CLL) the efficacy of SARS-CoV-2 vaccination remains unclear as most studies have focused on humoral responses. Here we comprehensively examined humoral and cellular responses to vaccine in CLL patients. Seroconversion was observed in 55.2% of CLL with lower rate and antibody titres in treated patients. T-cell responses were detected in a significant fraction of patients. CD4+ and CD8+ frequencies were significantly increased independent of serology with higher levels of CD4+ cells in patients under a Bruton tyrosine kinase (BTK) or a B-cell lymphoma 2 (BCL-2) inhibitor. Vaccination skewed CD8+ cells towards a highly cytotoxic phenotype, more pronounced in seroconverted patients. A high proportion of patients showed spike-specific CD4+ and CD8+ cells producing interferon gamma (IFNγ) and tumour necrosis factor alpha (TNFα). Patients under a BTK inhibitor showed increased production of IFNγ and TNFα by CD4+ cells. Vaccination induced a Th1 polarization reverting the Th2 CLL T-cell profile in the majority of patients with lower IL-4 production in untreated and BTK-inhibitor-treated patients. Such robust T-cell responses may have contributed to remarkable protection against hospitalization and death in a cohort of 540 patients. Combining T-cell metrics with seroprevalence may yield a more accurate measure of population immunity in CLL, providing consequential insights for public health.

Digital Health Care, Telemedicine, and Medicolegal Issues in Orthopedics: A Review.

The use of technologies in medicine has great potential to reduce the costs of health care services by making appropriate decisions that provide timely patient care. The evolution of telemedicine poses a series of clinical and medicolegal considerations. However, only a few articles have dealt with telemedicine and orthopedics. This review assesses the ethical and medicolegal issues related to tele-orthopedics. A systematic review was performed including papers published between 2017 and 2021 focusing on the main medicolegal and clinical-governance aspects of tele-orthopedics. Most of the articles were published during the COVID-19 pandemic, confirming the impetus that the pandemic has also given to the spread of telemedicine in the orthopedic field. The areas of interest dealt with in the scientific evidence, almost exclusively produced in the USA, Europe, the UK, and Canada, are quality, patient satisfaction, and safety. The impact of telemedicine in orthopedics has not yet been fully evaluated and studied in terms of the potential medicolegal concerns. Most of the authors performed qualitative studies with poor consistency. Authorizations and accreditations, protection of patient confidentiality, and professional responsibility are issues that will certainly soon emerge.

The epidemiology of proximal femur fractures during COVID-19 emergency in Italy: a multicentric study.

BACKGROUND AND AIM: After the first Italian case of Covid-19, the Government imposed the complete closure of all areas involved by the spread of the virus to contain transmissions. There was a massive reorganization of Hospitals, a stop of all elective activities and a convertion of many hospitals in "Covid Centers''. AITOG (Associazione Italiana Traumatologia e Ortopedia Geriatrica) conducted a retrospective study on all proximal femur fractures surgeries that occurred in this period, to find out whether the pandemic and the correlated lockdown somehow changed the incidence of these events.  Methods: 10 Italian orthopedic centers were involved in the study. Considering the geographic location, three groups were created (North, Centre and South). The considered period is the Italian "Phase 1" (February 23rd - May 3rd 2020). RESULTS: the cohort is composed of 412 patients, 116 male and 296 female (mean age 81.1 ± 9.1 years). The same period of 2019 has been used as control group, with 558 patients, 156 male and 402 female (mean age 84.2 ± 8.0 years). In 2020 we counted 323 (78.4%) fractures occurred at home, 61 (14.8%) in retirement houses and 28 (6.8%) in different locations. We mainly treated fractures with intramedullary nails (n.237 57.5%). Among all patients we had 46 (11.1%) Covid-19 positive. The mortality rate within 30 days was of 51 patients (12.4%); 23 of these died because of complications related to Covid-19 while 31 of  these were in treatment with anticoagulant/antiaggregant. CONCLUSIONS: AITOG analysis demonstrates a decrease in surgical interventions for proximal femur fractures from 2019 to 2020, a reduction in patients mean age and an increase in trauma occurred in domestic environment. We also registered a consistent difference between the North, Center and South of the Country.

The psychological and clinical impact of the COVID-19 pandemic on orthopaedic patients: An Italian gender-specific analysis.

This observational study aims to assess the impact of the COVID-19 pandemic on orthopaedic patients' psychology and clinical management, focusing on gender differences in the following items: (1) pain perception and therapeutic compliance during the pandemic, compared with the pre-pandemic period; (2) relationship doctorpatient (considering both general practitioners and orthopaedic surgeons); (3) patient referral to Orthopaedic emergency room. An Ad Hoc online questionnaire was developed and administered to patients referring to Orthopaedic emergency departments and Orthopaedic outpatient departments throughout Italy, between March and April 2020. The patients' psychological status during the pandemic was evaluated, mainly focusing on the following aspects, i.e., the fear of contracting the COVID-19 infection, the perceived risk of COVID-19 contagion and the compliance with the COVID-19 restrictions. Differences between genders were also assessed. 782 patients finally took part in the present study. A significant decrease of general practitioner and Orthopaedic surgeon clinical referral was recorded during the lockdown period, compared with pre-COVID period (p<0.001; p=0.031). Nonetheless, the number of phone calls to the general practitioner did not undergo substantial differences (p=0.093), compared to patients' the phone consult with orthopaedic surgeons (p=0.042). A significant correlation was found between the fear of COVID-19 contagion the perceived risk of contracting the infection (p<0.001). The COVID pandemic significantly impacted on orthopaedic patients' psychology and perception of the disease. During the lockdown, patients gave a higher priority to the pandemic event and significantly reduced the treatment of their orthopaedic disease.

The orthopaedic and traumatology scenario during Covid-19 outbreak in Italy: chronicles of a silent war.

BACKGROUND: From February 21, the day of hospitalisation in ICU of the first diagnosed case of Covid-19, the social situation and the hospitals' organisation throughout Italy dramatically changed. METHODS: The CIO (Club Italiano dell'Osteosintesi) is an Italian society devoted to the study of traumatology that counts members spread in public and private hospitals throughout the country. Fifteen members of the CIO, Chairmen of 15 Orthopaedic and Trauma Units of level 1 or 2 trauma centres in Italy, have been involved in the study. They were asked to record data about surgical, outpatients clinics and ER activity from the 23rd of February to the 4th of April 2020. The data collected were compared with the data of the same timeframe of the previous year (2019). RESULTS: Comparing with last year, overall outpatient activity reduced up to 75%, overall Emergency Room (ER) trauma consultations up to 71%, elective surgical activity reduced up to 100% within two weeks and trauma surgery excluding femoral neck fractures up to 50%. The surgical treatment of femoral neck fractures showed a stable reduction from 15 to 20% without a significant variation during the timeframe. CONCLUSIONS: Covid-19 outbreak showed a tremendous impact on all orthopaedic trauma activities throughout the country except for the surgical treatment of femoral neck fractures, which, although reduced, did not change in percentage within the analysed timeframe.

Mental Health Conditions of Italian Healthcare Professionals during the COVID-19 Disease Outbreak.

BACKGROUND: The COVID-19 pandemic in Italy represents a unique threat in terms of psychological distress. This cross-sectional study aims to investigate the psychological health of Italian healthcare professionals during the COVID-19 outbreak. We assessed participants' current psychological distress and coping strategies in the midst of the COVID outbreak (March-April 2020), and also asked them to retrospectively report how they remember feeling before the COVID-19 outbreak (December 2019). We examined associations between psychological distress and coping strategies with mental health and infection perceptions. METHODS: Self-administered questionnaires were distributed online to healthcare professionals (N = 580) residing in different Italian regions from 26 March to 9 April 2020. The questionnaire measured changes in psychological states, coping strategies, and demographic variables testing variations in mental health and infection risk perception among Italian healthcare workers. RESULTS: Overall, approximately 33.5 per cent of healthcare professionals in our sample meet the threshold for psychiatric morbidity. Participants perceive their current psychological health to be worse during the COVID-19 emergency outbreak as compared to before the outbreak, and this was especially true among women. CONCLUSIONS: Both immediate and long-term monitoring psychological assistance services for healthcare workers should be implemented by national institutions to re-establish the psychological well-being and enhance the self-confidence and resilience of hospital personnel.
