<p>The notion of Fourth Industrial Revulution(4IR) and Sustainable Development Goals (SDGs) are concurrent. Both are global issue which are equally important to each and evry country and interconnected in many ways. This study is qualitative and performed both content and contextual analysis (Silverman, 1993) to address how the 4IR could contribute and/or restrain to achieve the SDGs, particularly in Bangladesh. The papers were first sorted and further scrutinized to identify the links between 4IR and the SDGs. That Paper revealed that 4IR is a great enabler to achieve SDGs, outweighing the negatives of 4IR. Further research could quantitatively address the nexus between SDGs and 4IR further to draw specific research implications. It is also suggested to consider a particular country and/or industry for looking closely. Hopefully, the study will be proven useful for decision-makers of businesses and governments to understand and adopt the right strategies to attain SDGs and exploit 4IR.</p>

Background This study aimed to examine the differences in epidemiologic and disease aspects among patients with COVID 19 Methods: We reviewed the hospital records between April 2020 and September 2021 and followed up on the patients for post COVID complications. Findings: Older adult patients were predominantly affected during the first and second waves, followed by middle-aged patients. Men were predominantly admitted, considering the three waves; although more women were admitted in the second wave. Cough was more common in the second and third waves than in the first wave 522 (59.7%). Respiratory distress was the most common in the third wave, 251(67.1%), and least common in the first wave 403 (46.1%). Anosmia was more common in the third wave 116 (31.2%). In the third wave, patients presenting in a critical state 23 (6.2%) and severe disease 152 (40.8%) were more common. The hospital admission median (IQR) was longer in the first wave, 12 (8–20), than in other waves. More patients were admitted in the first wave (52%) than in the other waves, and patients received more oxygen in the third wave (75%) than in the other waves. Death occurred more commonly in the first wave (51%) than in the other waves. Patients were investigated more commonly in the first and third waves than in the second wave. The positivity rate was high in the third wave (22.8%) than in other waves. In the third wave, the positivity rate was higher in women (24.3%) than in men. Post COVID cough increased in the second wave and fatigue was higher in the third wave than in other waves. Tiredness and memory loss was greater during the second wave than in other waves. Conclusion: This study revealed that the presenting symptoms, outcomes, and epidemiologic trends differed during the COVID 19 waves.
