Abstract
ABSTRACT Objective : Numerous epidemiological studies have identified a potential link between sepsis and a variety of autoimmune disorders. The primary objective of this study is to delve deeper into this connection, investigating the potential causal relationship between sepsis and autoimmune disorders through the application of Mendelian randomization (MR). Methods : To assess the potential genetic impact on sepsis risk relating to susceptibility toward immune-related outcomes, we used summary data from the largest European genome-wide association studies (GWAS) on these conditions using a two-sample MR framework. Single nucleotide polymorphisms-which had strong associations with the nine traits-were extracted from the GWAS and examined their effects in an extensive European sepsis GWAS (486,484 cases and 474,841 controls). We used inverse-variance weighted MR, weighted median, and MR Egger for analyses, supplementing these with sensitivity analyses and assessing level pleiotropy using MR methodologies. We also executed a reverse MR analysis to test sepsis' causal effects on the designated autoimmune traits. Results : With primary sclerosing cholangitis being the exception, our MR analysis suggests that susceptibility toward most autoimmune diseases does not affect sepsis risks. The reverse MR analysis did not validate any influence of sepsis susceptibility over other autoimmune diseases. Our primary inverse-variance weighted MR analysis outcomes found general confirmation through our sensitivity MR examinations. Variance in the exposures, as dictated by the single nucleotide polymorphism sets used as MR instruments, ranged between 4.88 × 10 -5 to 0.005. Conclusion : Our MR research, centered on a European population, does not validate a correlation between susceptibility to the majority of autoimmune disorders and sepsis risk. Associations discerned in epidemiological studies may owe partly to shared biological or environmental confounders. The risk susceptibility for primary sclerosing cholangitis does relate to sepsis risk, opening doors for personalized precision treatments in the future.

Abstract
Various disorders can cause acute onset ataxia including those that have toxic/metabolic, traumatic, neoplastic, vascular, demyelinating/dysmyelinating, infectious, postinfectious and genetic features. We present a case of postseptic acute ataxia. A 72-year-old woman was diagnosed with septic shock secondary to acute obstructive suppurative cholangitis. A blood sample for bacterial culture was positive for Klebsiella pneumoniae Thus, we initiated antibiotics and intravenous immunoglobulin therapies to control the infection. We later added extracorporeal endotoxin removal with a polymyxin B immobilised fibre cartridge for endotoxin shock. The patient's condition improved soon after endotoxin removal. Mildly slurred and explosive speech with limb and truncal ataxia, which improved gradually, developed shortly afterwards. Serum samples obtained on day 15 after admission were positive for anti-GD1b IgG antibody. The clinical course of monophasic illness with good recovery, neurological findings and the appearance of anti-GD1b antibody suggest that this case is a variant of Miller-Fisher syndrome.

Abstract
Guillain-Barré syndrome (GBS) is an immune-mediated polyneuropathy classically thought to be caused by infections through the process of molecular mimicry. We report a case of GBS caused by intracerebral haemorrhage and postulate potential theories for the development of GBS following intracerebral haemorrhage and other non-infectious aetiologies by association. We highlight that GBS is an important differential diagnosis in patients developing generalised paresis following intracerebral haemorrhage.

Abstract
Guillain–Barré syndrome (GBS) is an acute, immune-mediated inflammatory peripheral polyneuropathy that is characterized by flaccid paralysis. A few cases have reported that GBS can be caused by head trauma or neurosurgery, but it has never been associated with intraventricular hemorrhage. Here, we report an uncommon case of fulminant GBS that occurred after spontaneous intraventricular hemorrhage. A 73-year-old woman was admitted to the hospital after sudden unconsciousness and vomiting. A head computed tomography (CT) scan following the incident showed a newly developed intraventricular hemorrhage, which led to an immediate ventriculostomy. After 5 days, the endotracheal tube was removed. Two days later, the external ventricular drainage tube was also removed. At this time, the patient was alert and the neurological examination was normal. However, the patient suddenly presented with acute respiratory failure and bilateral limb weakness 3 days later. An analysis of the patient’s cerebrospinal fluid (CSF) revealed that albuminocytologic dissociation was present. The patient was treated with intravenous immunoglobulin (0.4 g/kg/day) for 5 days. Despite timely medical intervention in the hospital, the patient passed away 2 months later. After a cerebral hemorrhagic injury, limb and respiratory muscle weakness can occur on occasion in the ICU. In this context, the potential involvement of GBS should not be ignored. Importantly, the pathogenic mechanism of GBS has been discussed for over a century, and it still remains a mystery. We speculate that the TLR4/NF-κB signaling pathway may be involved in the pathogenesis of GBS following intraventricular hemorrhage. The prognosis of most patients with GBS is usually good, but cerebral hemorrhage and mechanical ventilation may serve as risk factors that exacerbate the condition. This case is reported to remind clinicians to consider the possibility of GBS when patients present limb and respiratory muscle weakness after intraventricular hemorrhage, and to provide a starting point to discuss potential mechanisms of GBS after intraventricular hemorrhage.

Abstract
BACKGROUND Guillain-Barré syndrome (GBS) is an uncommon, yet life-threatening postoperative neuropathic complication that is easily neglected, and hence, timely treatment is not provided in the clinics. This review aims to summarize the clinical features of postoperative GBS, and thus, improve the understanding of postoperative GBS. METHODS We reviewed the literature on postoperative GBS and assessed the demographic information, clinical manifestation, operation, time of onset of postoperative GBS, and prognosis. RESULTS A total of 33 cases of postoperative GBS were included in this study. The average age of patients with postoperative GBS was 46.9 years, and there was a peak in occurrence of GBS between ages 50 and 70 years. Men seemed more likely to have postoperative GBS than did women, with a ratio of 2.67:1. Progressive muscular weakness, present in 31 of the cases, was the most common presentation. Patients with spinal surgery were at further increased risk for GBS, and 84.8% of the patients with GBS had a good prognosis after prompt treatment. CONCLUSIONS Surgery is probably a potential risk factor for the occurrence of GBS. Early diagnosis and prompt treatment are imperative to reduce mortality.

Abstract
We aimed to study the potential relationship of Guillain-Barré syndrome (GBS) and intracranial haemorrhage (ICH). We present a case of a 70-year-old hypertensive woman who developed global weakness, eventually becoming quadriplegic, during an inpatient stay for treatment of a basal ganglia haemorrhagic stroke. Guillain-Barré syndrome was confirmed and treatment initiated. She responded well to intravenous immunoglobulin treatment and then subsequently continued with rehabilitation. There have been a few case reports of GBS as a complication of spontaneous intracranial haemorrhage (ICH) or traumatic brain injury. It may not be a coincidence that our patient developed GBS shortly after presentation. There may be an immunological explanation with immune activation following neuronal injury after ICH with associated blood-brain barrier breakdown. GBS following ICH adds further complexity to treating patients who are already critically ill. If patients develop new weakness after ICH, there should be a high index of suspicion for GBS. It should be distinguished from critical illness neuropathy/myopathy and other causes of weakness in critical care patients because the treatment is very different. Immune activation and sensitization to myelin-associated proteins may be the underlying pathophysiological basis.

Abstract
Bacterial infectious pneumonia is one of the major causes of mortality in neonates, particularly when the neonates suffer from ventilator‑associated pneumonia (VAP). However, the causes of pneumonia are difficult to define. Thus, the present study focused on understanding the diversity of microflora in the lower respiratory tract to elucidate the causes. The experimental groups comprised newborns who suffered from infectious pneumonia with or without VAP (IVAP and IP groups, respectively), whereas the control group comprised newborns who suffered from respiratory distress syndrome (RDS) without VAP (RDS group). Following 1, 3 and 5 days of ventilation, sputum samples were collected and the DNA was extracted. The DNA was amplified and separated, and the 16S rDNA was then sequenced and analyzed for diversity. The results of the diversity and Shannon‑Wiener indices were ordered as follows: IVAP group < IP group < RDS group. The percentages of Streptococcus sp., Serratia sp. and Achromobacter sp. in the IP and IVAP groups were higher, compared with those in the RDS group, whereas the percentages of Klebsiella sp. and Acinetobacter sp. were lower on day 1. The percentages of Klebsiella sp. and Streptococcus sp. on days 1 and 3 were ordered as follows: IVAP group > IP group > RDS group, and the percentages of Serratia sp., Acinetobacter sp. and Achromobacter sp. were ordered as follows: IVAP group < IP group < RDS group. After 3‑5 days, the percentages of Klebsiella sp., Acinetobacter sp., Streptococcus sp., Serratia sp. and Achromobacter sp. in the IVAP group were lower, compared with those in the RDS and IP groups. It was concluded that the decreased microfloral diversity, increased constituent ratios of Klebsiella sp. and Streptococcus sp., and decreased ratios of Serratia sp. and Acinetobacter sp. in the lower respiratory tract of neonates suffering from pneumonia may be indicators of VAP.
