It has been considered that viral infections predispose patients to bacterial infections due to immunosuppression.3 However, it is still unclear what exact roles co-infections play in patients with COVID-19 infection1. Centers for Disease Control and Prevention defines co -infection as an infection concurrent with the initial infection. This report discusses a case of meningoencephalitis presenting with seizures. Notable in this case was the detection of SARS-CoV-2 RNA and Salmonella in the CSF.

Objectives. The ongoing Coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare systems worldwide. This study aimed to document the effect of COVID-19 on osteosarcoma treatment pathways in the Philippine General Hospital (PGH) and determine if there were any delays. Method. A retrospective review of osteosarcoma patients treated at the PGH from January 1, 2019 – January 1, 2020 (pre-COVID-19) was compared to those treated during the COVID-19 pandemic from March 1, 2020 – September 1, 2020. Rates of diagnosed osteosarcoma, admission for chemotherapy, admission for surgery, treatment abandonment, metastatic disease on presentation, 1-year mortality, and amputation were calculated and compared between the two groups. Results. From March to September 2020, 11 newly diagnosed osteosarcoma patients sought consult at the PGH. Only one patient sought consult during the initial 3-4 months of the study, suggesting that patients delayed seeking healthcare during the period of enhanced community quarantine. Patients seen during the pandemic had a higher rate of metastatic disease on presentation, reflecting the delay in diagnosis. Due to COVID-19 restrictions early in the pandemic, osteosarcoma patients were coordinated and referred to outside hospitals for intravenous chemotherapy and surgery. Normalization of services (hospital admissions, limb salvage surgeries) were seen at the later stages of the study, corresponding to the loosening of the quarantine. Conclusions. Osteosarcoma patients experienced delays in seeking consult, diagnosis, and treatment at the PGH due to the COVID-19 pandemic. Early indicators suggest worse outcomes for these patients due to the delays. Strategies employed during the pandemic, such as networking of care and telemedicine, may help in future outbreaks.

One of the consequences of the COVID-19 pandemic is an avalanche of information that is unprecedented in magnitude. In the past 2 months, healthcare providers, policy-makers and the general public have been overwhelmed by this phenomenon. Aside from usual news from TV, radio, newspapers and medical journals, people from all walks of life have had to process kilometric threads on viber, facebook and twitter, as well as hundreds of issuances from all government agencies - from the Office of the President down to the barangays. The information from these various sources are often inconsistent or conflicting, and are always rapidly evolving. New information emerges as outdated information is just beginning to circulate. To aggravate the situation, the chaos is taken advantage of by perpetrators of false information. Clearly, this “informageddon” has led to “information overload” – the inability to process facts because of volume or pace. The manifestation is the widespread panic we are witnessing from all sectors of society. The consequence is impaired decision making – by individuals, families, communities and policy makers. Ultimately, this may lead to a prolonged, uncontrolled pandemic characterized by avoidable deaths, disability, and huge social and economic costs. Even healthcare providers are affected. Because of fear, many feel pressured to do tests and give treatments for COVID-19, that are poorly tested for effectiveness and safety. To help manage the information for policy-makers, healthcare workers and the general public, a group of 70 clinical epidemiologists and health professionals gathered together from the Institute of Clinical Epidemiology, National Institutes of Health-UP Manila and the Asia-Pacific Center for Evidence Based Healthcare Inc. The group conducted voluntary rapid evidence reviews and referred to themselves as “The Rappers”. The reviews were graciously shared by Philippine Society of Microbiology and Infectious Diseases through their website (PSMID.org). The online version allowed regular and rapid updates as evidence accrued.

KEY FINDINGS Based on laboratory-based studies, ultraviolet germicidal irradiation (UVGI), microwave generated steam, warm moist heat, and hydrogen peroxide vapor (HPV) were able to reduce the load of influenza viruses (A/H5N1, H1N1) or G. stearothermophilus and at the same time maintain the integrity of N95 respirators. • Considering the current pandemic, there is a potential for shortage of N95 facepiece filtering respirator (FFR) for healthcare workers. • No studies in humans were found comparing effectiveness of N95 post-decontamination. • Laboratory based studies done on influenza virus (A/H5N1, H1N1) have shown that ultraviolet germicidal irradiation, microwave generated steam, or warm moist heat was able to reduce the viral load by as much as 4 log and at the same time maintain respirator performance by keeping the percent penetration below 5% and the pressure drop within standards. • While UVGI was able to maintain integrity of FFRs up to 3 cycles, microwave generated steam may melt the metallic components of certain N95 masks. • Hydrogen peroxide vapor (HPV) had minimal effect on respirator performance and structural integrity up to 20 cycles and was also effective in eradicating G. stearothermophilus and aerosolized bacteriophages. • Bleach, ethanol and isopropanol all affected the mean penetration of the mask beyond the 5% limit. • The Centers for Disease Control (CDC) does not recommend decontamination then reuse of FFRs as standard care but decontamination with UVGI, HPV or moist heat may be considered as an option in FFR shortages.

Key Findings Current evidence does NOT support use of IgM/IgG rapid test kits for the definitive diagnosis of COVID-19 in currently symptomatic patients. • The present standard for diagnosis of COVID-19 is through qualitative detection of COVID-19 virus nucleic acid via reverse transcription polymerase chain reaction (RT-PCR). • Due to long turnaround times and complicated logistical operations, a rapid and simple field test alternative is needed to diagnose and screen patients. • An alternative to the direct detection and measurement of viral load (RT-PCR) is the qualitative detection of specific antibodies to COVID-19. ELISA (discussed in a separate rapid review) and lateral flow immunoassay (LFIA) IgM/IgG rapid test kits are two currently available, qualitative, antibody tests for COVID-19. • Two low quality clinical trials showed that there is insufficient evidence to support the use of IgM/IgG rapid test kits for the definitive diagnosis of COVID-19. Diagnostic accuracy varies greatly depending on the timing of the test. The test performed very poorly during the early phase of the disease (i.e., less than eight days from onset of symptoms). • Existing guidelines do not recommend serologic antibody tests for the diagnosis of COVID-19 in currently symptomatic patients.

Key Findings Several laboratory tests are found to be associated with disease severity and mortality in COVID-19, and may be used to prognosticate patients and guide management. • Around 20% of COVID-19 patients develop severe illness that may require intensive care and lead to fatal complications. This necessitates prioritization of patients requiring urgent medical care before disease progression. • Certain laboratory markers (biomarkers) may reflect the processes involved in the clinical deterioration of infected patients. Hence, their use in the identification of patients at high risk of progression to severe disease or death has been investigated. • Current available evidence shows that the following laboratory abnormalities in a person with COVID-19, especially when found early during hospitalization, are associated with severe or critical disease or mortality: 1. Markers of organ dysfunction a. Reduced oxygen saturation b. Elevated lactic dehydrogenase (LDH) c. Elevated blood urea nitrogen (BUN) or serum creatinine d. Elevated cardiac troponin (cTnI) e. Elevated direct bilirubin, reduced albumin f. High radiographic score or CT severity score, or consolidation on CT scan 2. Marker of abnormal coagulation – D-dimer 3. Markers of immune dysfunction a. Elevated IL-6 b. Elevated C-reactive protein (CRP) c. Elevated neutrophils d. Reduced lymphocyte percentage e. Reduced CD4+ T lymphocytes 4. Secondary bacterial infection – Elevated procalcitonin • Proposed prediction models utilizing these markers, however, need further validation before they can be recommended for routine clinical use.

Key Findings There is no direct evidence available as of this point for efficacy of intravenous vitamin C as an adjunctive treatment in preventing mortality or shortening disease course among adults suspected of, or positive for COVID-19. • Vitamin C is currently not mentioned in the treatment guidelines for COVID. • Currently, there are 3 ongoing trials registered in clinicaltrials.gov studying intravenous vitamin C in COVID-19. No other ongoing or planned trials were registered in the other trial registries. • Most of the available data are from studies on disease populations which may be considered as COVID-19 suspects:  Conflicting results on mortality from indirect evidence among patients with sepsis with or without ARDS with significant reduction in mortality found in only a small subset of patients (n-40) with severe sepsis given high dose Vitamin C infusion.  Strong evidence supporting no mortality benefit from 5 meta-analyses on critically ill patients due to conditions other than or in combination with sepsis who were given Vit C infusion alone or in combinations with other medications. One meta-analysis showed benefit in decreasing duration of ICU stay and mechanical ventilation but sample size is small. Most showed no benefit on and other key endpoints such as acute kidney injury, duration of hospital stay/ ICU stay/ duration of vasopressor use or duration of mechanical ventilation. • The use of Vit C infusion is not mentioned in the treatment guidelines for COVID-19 or ARDS. • The risks or adverse events with short term use of Vitamin C infusion in the general population is negligible or minimal. It should be avoided in patients with G6PD insufficiency. The dose should be carefully adjusted for patients with renal insufficiency.
