COVID-19 Pandemic: A Serious Threat for Public Mental Health Globally.

Deep emotion traumas in societies around the globe are overcome by extreme human catastrophes such as natural disasters, social crises, war conflicts and infectious virus induced pandemic diseases, etc., can lead to enormous stress-related disorders. The current ongoing pandemic known as COVID-19 caused by novel Corona virus first appeared in Wuhan, city of China and then rapidly spread in the whole world. It has affected various frontiers of lives and caused numerous psychiatric problems like nervousness, post-traumatic stress disorder (PTSD), fear and uncertainty, panic attacks, depression, obsessive compulsory disorder, xenophobia and racism, etc. Globally COVID-19 has persuaded public mental health crisis. Furthermore, inadequate resources of public mental health services in several countries are discussed in this review, which will be further straighten by the upcoming increase in demand for mental health services due to the COVID-19 pandemic. All mental health sciences including Psychiatry can play a very important role in the comfort of COVID-19 infected individuals and their relatives, healthcare providers and society. We need to learn more about psychological and psychiatric features of COVID-19 from the perceptions of public and global mental health in order to cope up the present deteriorating situation caused by the SARS-CoV-2 pandemic.

Presence of T3SS (exoS, exoT, exoU and exoY), susceptibility pattern and MIC of MDR-Pseudomonas aeruginosa from burn wounds.

INTRODUCTION: The emergence of resistance is a major public health and clinical issue, particularly in pathogens causing nosocomial infections. Recently, there is the emergence of Pseudomonas aeruginosa resistance to different broad-spectrum antibiotics. METHODOLOGY: The current study was designed to find out the prevalence of multi-drug resistant (MDR) P. aeruginosa in burn patients, the antibiotic susceptibility pattern of MDR Pseudomonas, and to determine the Minimum Inhibitory Concentration (MIC) of the effective antimicrobials. The assessment of virulence genes (exoT, exoS, exoY and exoU) was also achieved through PCR. In the current study wound swabs were collected from 160 burn patients from two burn units (MTI-Govt. Lady Reading Hospital and MTI-Khyber Teaching Hospital). RESULTS: Out of these 160 samples, 26 samples (16.25%) were positive for P. aeruginosa. Per patients, one isolate was included in the current study. Antibiotic susceptibility pattern showed all P. aeruginosa isolates were 100% resistant to amoxicillin-clavulanic acid, 84.62% resistance to Cefepime, and Ceftazidime, and 76.92% resistance to Amikacin, Aztreonam, and Ciprofloxacin. Whereas the lowest resistance was observed to Imipenem and Piperacillin-Tazobactam (53.85%), Colistin Sulfate (23.08%), and Polymyxin-B (15.38%). Regarding the prevalence of MDR, 22 (84.61%) isolates out of 26 were found to be MDR-P. aeruginosa. For MDR-P. aeruginosa, the MIC range was 1-2 µg/mL against Polymyxin-B, 2-8 µg/mL against Colistin sulfate, 16-1024 µg/mL against Imipenem and 128-1024 µg/mL against Piperacillin-Tazobactam. 100% of the isolates carried exoT, 88.46% carried exoY, and 57.69% and 38.46% carried exoU and exoS, respectively. CONCLUSIONS: These findings further emphasize the need for antibiotic discipline and to follow the recommended hospital antibiotic policy to prevent the proliferation of MDR strains of P. aeruginosa in the community.

Dysbiosis in salivary bacterial diversity of postpartum females and its association with oral health problems and APOs.

The present study investigates the dysbiosis in salivary bacterial diversity by culture-dependent and independent methods. Culturable aerobic and facultative anaerobic bacterial diversity was studied in saliva collected from 267 postpartum and 54 nonpregnant females by using standard microbiological methods. For unculturable bacterial diversity, DNA from saliva samples of four selected females was sequenced by targeting V4 region of 16S rRNA. In postpartum females, S. mutans was significantly more prevalent. Its colonization was also seen significant among females having gingivitis (P < 0.01), dental caries (P < 0.01), and in those giving birth to low weight baby. In postpartum group, 65.16% females were culture positive for Staphylococcus, 12.73% Gram positive rods, 10.48% N. meningitides, 6.36% K. pneumoniae, 5.61% Enterobacter species and 2.62% E. coli. Isolates showed high biofilm forming ability and antibiotic resistance. Upon analysis of unculturable bacterial diversity, a total of 16 phyla and 156 genera were observed. Alpha diversity was decrease in postpartum female having oral health issues with pre-term low weight birth, compared to females with full term birth. Bray-Curtis dissimilarity was highest between female with dental issues and different pregnancy outcomes. Bacterial diversity and abundance altered among females with different oral health conditions and pregnancy outcomes, and also have pathogenic potential.
