Summary: Whole-genome sequencing analysis of three COVID-19-confirmed patients revealed that the haplotype diversity of SARS-CoV-2 may lead to viral adaptation for persistent shedding in multiple recurrences, impacting the clinical management of COVID-19 patients with long-term hospitalization or cases of recurrence.

Summary: The evolving nature of SARS-CoV-2 requires periodic revisions of COVID-19 patient treatment and discharge guidelines. The WHO plays a crucial role in handling country-level pandemic preparedness and patient management protocols. Patients can be released from isolation centers on the 10th day following clinical symptom manifestation, with at least 72 additional hours following the resolution of symptoms.

Summary: Insufficient vaccine production remains a major obstacle to achieving herd immunity, leading to frequent re-positive cases and controversy about their infectivity. A study in China found that patients who tested re-positive for COVID-19 displayed different blood indicators, with lower levels of serum creatinine and albumin at the time of initial diagnosis, and significantly different eosinophil counts during two positive phases and the middle negative phase. Eosinophil levels in peripheral blood can potentially serve as a marker to predict re-positive cases in individuals with a history of COVID-19 infection.

Summary: Early in the COVID-19 pandemic, hydroxychloroquine was considered as a potential early treatment to prevent clinical worsening. However, this study found that hydroxychloroquine did not significantly alter the natural history of early COVID-19 disease.

Summary: Remdesivir is the first approved treatment for COVID-19, showing therapeutic and prophylactic effects in animal models of various viruses. However, it failed in a clinical trial on ebolavirus disease but showed beneficial effects for patients with COVID-19 in a placebo-controlled trial.

Summary: The study found that asymptomatic COVID-19 patients have a similar viral load to symptomatic patients during the early stages of the disease, but their infectivity rapidly decreases with the loss of symptoms.

Summary: COVID-19 patients are discharged based on two consecutive negative viral RNA tests, improved respiratory symptoms, and obvious absorption of inflammation in pulmonary imaging. Differences in various blood cell counts and infection-related parameters were found between severe and non-severe groups. Higher counts of certain immune cells were associated with faster clearance of the virus and better outcomes.

Summary: This study found that asymptomatic carriers of SARS-CoV-2 have a higher antiviral immunity compared to symptomatic COVID-19 patients, with quicker conversion of IgM antibodies and a higher proportion of seropositivity for IgG against SARS-CoV-2. The severity of COVID-19 is associated with older age and comorbidities in familial clustering cases.

Summary: This study found that re-positive COVID-19 cases have very low viral loads, making the patients non-infectious with extremely low risk of human-to-human transmission. Re-positive patients should undergo home health management.

Summary: The COVID-19 pandemic has had a significant impact on organ donation and transplantation globally. Based on current experience, transplantation of non-lung organs from deceased donors with active SARS-CoV-2 infection has been considered possible and safe. With the evolving outbreak and the availability of vaccines and treatments, organs from deceased donors with active SARS-CoV-2 infection may be considered for transplantation in recipients with limited opportunities and specific immunity. Expert opinions are provided in the absence of definitive data and standardized acceptance patterns.

Summary: The COVID-19 epidemic of 2019-20 is caused by the novel coronavirus SARS-CoV-2, which has infected millions worldwide. This study aimed to determine if SARS-CoV-2 sequence variants are linked to different outcomes among COVID-19 patients in a single medical system. The virus has shown rapid mutation with two major clades of sequence variants identified.

Summary: This study presents results from a multiplex serology test for assessing COVID-19 antibody responses, showing distinct dynamics of IgG, IgM, and IgA responses in patients with different disease severity. It suggests that antibody responses to SARS-CoV-2 may serve as important biomarkers for assessing the risk of viral transmission.

Summary: This study comprehensively characterized the immune responses of asymptomatic COVID-19 patients, finding that they exhibit stronger protective mechanisms, lower levels of pro-inflammatory responses, and more effective immune responses compared to symptomatic patients. Additionally, asymptomatic patients had higher levels of growth factors associated with cellular repair in their bodies.

Summary: The study in Brunei revealed that around one-third of TB patients also had diabetes mellitus, with the majority being diagnosed with diabetes at least six months before TB diagnosis. Factors such as age, smear-positive pulmonary TB, hypertension/heart disease, renal disease, and chronic obstructive pulmonary disease/asthma were significantly associated with the comorbidity of TB and diabetes. Early detection and treatment of both diseases through bi-directional screening could be an effective strategy.

Summary: Research has shown that emerging market and developing economies that performed relatively well during the global recession typically have strong economic fundamentals, including large foreign exchange reserves, sound fiscal positions, and low inflation rates. Conversely, countries heavily reliant on short-term capital flows tend to be more vulnerable to economic shocks, especially those located in Europe and Central Asia.
