RESUMO
BACKGROUND: Much increasing evidence has suggested that long-term complications post vaccination of SARS-CoV-2 experience a wide range of complication including diabetes. The risk and burden of type 1 diabetes is extensively reported, but type 2 diabetes mellitus (T2D) has yet to be characterized. To address this gap, we aimed to examine trends of long-term complications post SARS-CoV-2 infection and vaccination in diabetes incidence among the Saudi population. METHODS: In this cross-sectional hospital-based study, we analyzed the blood profile of first-time blood donors from the University Hospital of King Abdulaziz University, Jeddah. Saudi Arabia. Various blood parameters, HbA1c was measured in the month of May 2023. All the donors were non-diabetic and were never diagnosed with T2D before the current blood donation. 203 healthy subjects donated their blood, out of which 104 had abnormally high HbA1c tending towards diagnosis of T2D and 99 had with blood profiles. The study followed the STROBE reporting guidelines. RESULTS: Out of 203 donors 104 (male 50(48.1%), female 54(51.9%)) were diagnosed with increased HbA1c (8.24 in males) compared to 7.61 of HbA1c in females. 35.6% were above Ë65 years, with 52.9% with O+ from the ABO blood group. Liver functions indicated significant pË0.05, 0.04, increased amount of GGT (46.47 U/L), Alkaline phosphatase (99.93 ±64.26 uL) respectively in HbA1c elevated donors KFT represented significant pË0.05, 0.02 elevated levels of urea (6.73 ±5.51 mmol/L), creatinine (129.97 ±195.17 umol/L) respectively along with elevated values of Lactate dehydrogenase (LDH) (263.72± 196.70 uL) and triglycerides (1.66 ±0.74mmol/L) when compared to normal value of HbA1c donors. DISCUSSION: In the present cross-sectional study, significant increase in HbA1c, trending towards increased cases of T2D post SARS-CoV-2 infection and vaccination. Males are much affected compared to females. Further maximum number of cases were from donors above the age of 65 years with altered partial LFT (GGT, Alkaline phosphatase), KFT (urea, creatinine), lipid profile (TG) and LDH in post SARS-CoV-2 and vaccination blood donors. CONCLUSION: Increase in HbA1c in 50% of donors, irrespective of gender, is an alarming figure for health authorities, with altered LFT, KFT and LDH tests and, in the near future, may increase the incidence of T2D. Large-scale population-based studies are required to prevent future incidences of T2D in young children who will be vaccinated.

Prunus amygdalus Batsch (almond) is a classical nutritive traditional Indian medicine. Along with nutritive with anti-oxidant properties, it is, clinically, used in the treatment of various diseases with underlying anti-oxidant mechanism. This study is an effort to scrutinise the renal protective effect of P. amygdalus Batsch or green almond (GA) seed coat extract and its underlying mechanism in animal model of Ferric nitrilotriacetate (Fe-NTA) induced renal cell carcinoma (RCC). RCC was induced in Swiss Albino Wistar rats by intraperitoneal injection of Fe-NTA. The rats were then treated with ethanolic extract of GA (25, 50 and 100 mg/kg per oral) for 22 weeks. Efficacy of GA administration was evaluated by change in biochemical, renal, macroscopical and histopathological parameters and alterations. Additionally, interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß) and inflammatory mediator including prostaglandin E2 (PGE2), nuclear factor-kappa B (NF-κB) were also observed to explore the possible mechanisms. The oral administration of GA significantly (p < .001) altered the Fe-NTA induced RCC in rats by inhibition of renal nodules, decolourisation of tissues, tumour promoter marker including thymidine 3[H] incorporation, ornithine decarboxylase, renal parameters and anti-oxidant parameters in serum. Additionally, GA treatment significantly (p < .001) down-regulated the IL-6, IL-1ß, TNF-α, inflammatory mediators PGE2 and NF-κB in a dose-dependent manner. Histopathology observation supported the renal protective effect of GA by alteration in necrosis, size of Bowman capsules and inflammatory cells. Hence, it can be concluded that GA possesses observable chemo-protective action and effect on Fe-NTA induced RCC via dual inhibition mechanism one by inhibiting free radical generation and second by inhibiting inflammation.

Almost half of the human genome is composed of transposable elements. The genomic structures and life cycles of some of these elements suggest they are a result of waves of retroviral infection and transposition over millions of years. The reduction of retrotransposition activity in primates compared to that in nonprimates, such as mice, has been attributed to the positive selection of several antiretroviral factors, such as apolipoprotein B mRNA editing enzymes. Among these, APOBEC3G is known to mutate G to A within the context of GG in the genome of endogenous as well as several exogenous retroelements (the underlining marks the G that is mutated). On the other hand, APOBEC3F and to a lesser extent other APOBEC3 members induce G-to-A changes within the nucleotide GA. It is known that these enzymes can induce deleterious mutations in the genome of retroviral sequences, but the evolution and/or inactivation of retroelements as a result of mutation by these proteins is not clear. Here, we analyze the mutation signatures of these proteins on large populations of long interspersed nuclear element (LINE), short interspersed nuclear element (SINE), and endogenous retrovirus (ERV) families in the human genome to infer possible evolutionary pressure and/or hypermutation events. Sequence context dependency of mutation by APOBEC3 allows investigation of the changes in the genome of retroelements by inspecting the depletion of G and enrichment of A within the APOBEC3 target and product motifs, respectively. Analysis of approximately 22,000 LINE-1 (L1), 24,000 SINE Alu, and 3,000 ERV sequences showed a footprint of GGâAG mutation by APOBEC3G and GAâAA mutation by other members of the APOBEC3 family (e.g., APOBEC3F) on the genome of ERV-K and ERV-1 elements but not on those of ERV-L, LINE, or SINE.
