Safe Blood

Blood is considered a scarce resource in the world. Many patients requiring transfusion do not have timely access to safe blood and many lives are lost because of this reason. According to the WHO Information Sheets, 2005 80% of the worldwide population has access to only 20% of safe blood. Aim- To analyse the donor profile and the need for voluntary blood donation drives. Methodology: A descriptive cross-sectional study conducted among blood donors attending the blood bank of a Tertiary care centre in South India from 2015 to 2019. Results: Out of 7979 blood donations, voluntary donors were only 8.5 % with most (97.8%) of the donors being males. The donors arriving at the blood bank were between 18 and 64 years of age. Of the voluntary donors, about 37% were first-time blood donors. The commonest available blood group was O positive (34.1%) and the least available was AB negative (0.8%). Among the reasons for donor rejection, mismatch between the donor’s blood group and that of the requested unit was the commonest (25.8%) followed by hypertension (22.9%) on examination. HBsAg seropositivity was the majority (0.5%) among the transfusion transmitted infections screened. Conclusion: Efforts should be made to direct all the donations towards voluntary non remunerated ones. Awareness among the general population about the need of blood donation, educating them about the criteria of acceptable donors and discussing the general myths and facts about donation process is also important.

ObjectiveTo assess the SARS-CoV-2 transmission in healthcare workers (HCWs) using seroprevalence as a surrogate marker of infection in our tertiary care centre according to exposure.DesignSeroprevalence cross-sectional study.SettingSingle centre at the end of the first COVID-19 wave in Lausanne, Switzerland.Participants1874 of 4074 responders randomly selected (46% response rate), stratified by work category among the 13 474 (13.9%) HCWs.Main outcome measuresEvaluation of SARS-CoV-2 serostatus paired with a questionnaire of SARS-CoV-2 acquisition risk factors internal and external to the workplace.ResultsThe overall SARS-CoV-2 seroprevalence rate among HCWs was 10.0% (95% CI 8.7% to 11.5%). HCWs with daily patient contact did not experience increased rates of seropositivity relative to those without (10.3% vs 9.6%, respectively, p=0.64). HCWs with direct contact with patients with COVID-19 or working in COVID-19 units did not experience increased seropositivity rates relative to their counterparts (10.4% vs 9.8%, p=0.69 and 10.6% vs 9.9%, p=0.69, respectively). However, specific locations of contact with patients irrespective of COVID-19 status—in patient rooms or reception areas—did correlate with increased rates of seropositivity (11.9% vs 7.5%, p=0.019 and 14.3% vs 9.2%, p=0.025, respectively). In contrast, HCWs with a suspected or proven SARS-CoV-2-infected household contact had significantly higher seropositivity rates than those without such contacts (19.0% vs 8.7%, p<0.001 and 42.1% vs 9.4%, p<0.001, respectively). Finally, consistent use of a mask on public transportation correlated with decreased seroprevalence (5.3% for mask users vs 11.2% for intermittent or no mask use, p=0.030).ConclusionsThe overall seroprevalence was 10% without significant differences in seroprevalence between HCWs exposed to patients with COVID-19 and HCWs not exposed. This suggests that, once fully in place, protective measures limited SARS-CoV-2 occupational acquisition within the hospital environment. SARS-CoV-2 seroconversion among HCWs was associated primarily with community risk factors, particularly household transmission.

Abstract Objective: To determine the nasal carriage of staphylococcus aureus and methicillin-resistant staphylococcus aureus among healthcare workers in a tertiary care setting. Methods: The cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from April to July 2018, and comprised healthcare workers at the institution. Nasal swabs were collected and cultured on Mannitol salt agar. Mannitol fermenting colonies which were gram-positive cocci, catalase-positive and coagulase-positive were identified as staphylococcus aureus. Antibiotic susceptibility test was performed by modified Kirby-Bauer disc diffusion method. Methicillin resistance was detected using cefoxitin disc diffusion method. Data was analysed using SPSS 23. Results: Of the 210 nasal swabs, 52(24.76%) had a staphylococcus aureus growth, and, of them, 15(7.1%) were methicillin-resistant. No association could be established with either any single category of healthcare worker or an inter-department variation (p>0.05). Likewise, there was no association with age, gender, duration of service, smoking, co-morbidities, use of antibiotics in the preceding six months, treating a patient with methicillin-resistant staphylococcus aureus in the preceding six months and hospitalisation in the preceding year (p>0.05). Conclusion: The frequency of nasal carriage of methicillin resistant staphylococcus aureus amongst healthcare workers was regardless of the nature of their professional engagement.
