7% and the risk for severe DKA increased by 45.3% compared to the years 2018/2019. Children <6years had the highest risk with an 141.6% increase for DKA and 97.0% for severe DKA compared to the previous years. Migration background was a risk factor independent of COVID-19. Of the patients 31% had either adelayed presentation or amissed diagnosis.
 
  During the COVID-19 lockdown the frequency of DKA and severe DKA at DM1 onset was significantly increased for children and adolescents in Germany. Age <6years, migration background and delayed diagnosis were the main risk factors.

The sensor based on hydrothermal synthesis of vanadium disulfide quantum dots (VS2 QDs) and insertion within 3D N, S graphene aerogel (3D N, S @ GNA) and carbon nanotubes nanaostructure as a new and widely group of carbon nanomaterials. The nanocomposites were characterized morphologically using different techniques. In addition, the nanomaterials were characterized electrochemically using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). The proposed electrochemical sensor showed wide dynamic linear ranges of 0.28-30 × 10-8 M and 0.84-22.5 × 10-8 M for analysis of AZM and HCQ, respectively. The limits of detection (LODs) based on signal to noise (S/N) 31 were found to be 0.091 × 10-8 M and 0.277 × 10-8 M for AZM and HCQ, respectively. Briefly, the electrochemical sensor had good stability, selectivity, reproducibility and feasibility for simultaneous detection of AZM and HCQ in presence of different interfering species.Voltage-gated potassium channels are integral membrane proteins selectively permeable for potassium ions and activated upon change of membrane potential. Voltage-gated potassium channels of the Kv1.3 type were discovered both in plasma membrane and in inner mitochondrial membrane (mito Kv1.3 channels). For some time Kv1.3 channels located both in plasma membrane and in mitochondria are considered as a potentially new molecular target in several pathologies including some cancer disorders. Lipophilic nontoxic organic inhibitors of Kv1.3 channels may potentially find a clinical application to support therapy of some cancer diseases such as breast, pancreas and lung cancer, melanoma or chronic lymphocytic leukaemia (B-CLL). Inhibition of T lymphocyte Kv1.3 channels may be also important in treatment of chronic and acute respiratory diseases including severe pulmonary complication in corona virus disease Covid 19, however further studies are needed to confirm this supposition. Statins are small-molecule organic cvated state of the channels.
  The best analgesic technique after hip surgeries is a matter of debate. This clinical trial aimed to assess the effect of transmuscular ultrasound-guided quadratus lumborum (QL) block on post-operative analgesic consumption after hip arthroplasty in elderly patients.
 
  This prospective randomised double-blind study was carried out on 60 patients aged 60-80 years presented for total hip replacement under unilateral spinal anaesthesia. Patients were randomly allocated to one of two groups A control group, receiving sham transmuscular QL block (QLB) (1 ml of normal saline), and a QL group, receiving real transmuscular QLB (30 ml of plain bupivacaine 0.25%). Post-operative morphine consumption (primary outcome), post-operative pain score (secondary outcome), time to the first request of rescue analgesia, patient's satisfaction and the occurrence of post-operative complications were measured.
 
  Compared to the control group, the use of QLB in the second group significantly decreased intravenous morphine consumption postoperatively from 8.50 ± 3.06 mg to 5.60 ± 3.22 mg (
  = 0.0007) with a significant prolongation of the time to the first call for analgesia (
  < 0.0001). It also decreased the post-operative visual analogue score 4 h, 6 h and 8 h postoperatively (
  < 0.05). However, there was no difference between both the groups regarding patient's satisfaction and the occurrence of complications (
  > 0.05).
 
  The use of transmuscular QLB in patients undergoing total hip replacement decreased post-operative analgesic consumption and post-operative pain score and prolonged post-operative analgesia. It did not affect patients' satisfaction and occurrence of post-operative complications.

  Post-operative cognitive dysfunction (POCD) is a poorly understood complication particularly observed in elderly patients, with long-term poor outcome. The randomised study was to compare the incidence of POCD in elderly with bispectral index (BIS)-guided intra-operative use of either dexmedetomidine or propofol with sevoflurane.
 
  Eighty-seven patients, planned for non-cardiac surgery under general anaesthesia, were included between June 2017 and March 2018. After exclusion of 7 patients, remaining 80 patients were randomised into dexmedetomidine group and propofol group with 40 patients each. In both the groups, BIS-guided anaesthesia was provided. Cognitive function was assessed by an anaesthesiologist using a battery of neuropsychological tests at baseline pre-operatively, third and seventh day after surgery. The data were entered into a Microsoft Excel spreadsheet and analysis was performed using Statistical Package for Social Sciences (SPSS) version 21.
 
  Propofol group had a non-significant lower incidence of POCD on third day and dexmedetomidine group showed decreased incidence of POCD on seventh day, accompanied by lower anaesthetic requirement (inhalational as well as intravenous) concomitant with delayed emergence with an acceptable BIS value.
 
  Dexmedetomidine appeared to be anaesthetic sparing as compared to propofol. BIS monitoring for titrating depth of anaesthesia and hence the anaesthetic exposure is an invaluable tool as compared to routine care anaesthesia for reducing POCD. The patients in both groups did not develop significant POCD until the seventh post-operative day.
