Are sodium-glucose co-transporter-2 inhibitors associated with improved outcomes in diabetic patients admitted to intensive care units with septic shock?

BACKGROUND: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have been shown to reduce organ dysfunction in renal and cardiovascular disease. There are limited data on the role of SGLT2i in acute organ dysfunction. We conducted a study to assess the effect of SGLT2i taken prior to intensive care unit (ICU) admission in diabetic patients admitted with septic shock. METHODS: This retrospective cohort study used electronic medical records and included diabetic patients admitted to the ICU with septic shock. We compared diabetic patients on SGLT2i to those who were not on SGLT2i prior to admission. The primary outcome was in-hospital mortality, and secondary outcomes included hospital and ICU length of stay, use of renal replacement therapy, and 28- and 90-day mortality. RESULTS: A total of 98 diabetic patients was included in the study, 36 in the SGLT2i group and 62 in the non-SGLT2i group. The Sequential Organ Failure Assessment and Acute Physiology and Chronic Health Evaluation III scores were similar in the groups. Inpatient mortality was significantly lower in the SGLT2i group (5.6% vs. 27.4%, P=0.008). There was no significant difference in secondary outcomes. CONCLUSIONS: Our study found that diabetic patients on SGLT2i prior to hospitalization who were admitted to the ICU with septic shock had lower inpatient mortality compared to patients not on SGLT2i.

Delayed Diagnosis of West Nile Meningoencephalitis in a Patient Receiving Rituximab for Rheumatoid Arthritis.

West Nile virus (WNV) neuroinvasive disease is associated with substantial morbidity and mortality. Clinical suspicion is usually confirmed with cerebrospinal (CSF) immunoglobulin M (IgM) detection using enzyme-linked immunoassay (ELISA) techniques. CSF polymerase chain reaction (PCR) is rarely used to confirm the disease and is not widely available. We present a detailed report of false-negative WNV IgM in a patient receiving rituximab therapy for rheumatoid arthritis. She was exposed to the virus during peak immunosuppression and strong clinical suspicion was confirmed with WNV PCR, illustrating the importance of such consideration with the recent incremental use of rituximab therapy. Despite the lack of specific anti-viral treatment for WNV, delayed consideration and diagnosis of WNV in those who are immunosuppressed would expose them to a wide panel of testing, with a subsequent increase in the cost of medical care.

Recurrent Lymphocytic Pleural Effusion as a Complication of Ventriculopleural Shunt Meningitis Caused by Cutibacterium Acnes.

Cutibacterium acnes (C. acnes) is part of the normal flora and has been linked to many invasive and pleural infections. Though it is usually considered a contaminant bacterium, full antimicrobial therapy might result in the resolution of foreign body-related infections. In this report, we describe an infection that started as ventriculopleural shunt meningitis but was complicated by a recurrent lymphocytic pleural infection. Ultimately, there was a resolution of pleural effusions after treatment of C. acnes.

Breaking bad news from the doctors' perspective in a paternalistic society: the case of Sudan.

Breaking bad news is a global challenge for all types of health providers. Our study assessed the attitude and practice from the doctors' perspective in a patriarchal society. A descriptive cross-sectional hospital-based study was conducted, involving doctors from both medical and surgical departments. Almost half of the respondents believed that Sudanese patients do not like to know their diagnosis, and a slightly higher proportion had no previous training on how to break bad news. Some 20% indicated that they would conceal the diagnosis from a patient if his or her relatives so requested. Less than one-quarter of respondents followed a standard protocol. Although most of the doctors subscribed to the notion that patients have the right to know everything about their illnesses, not all of them held this attitude towards their local patient population.

Monoallelic characteristic-bearing heterozygous L1053X in BRCA2 gene among Sudanese women with breast cancer.

BACKGROUND: Breast cancer (BC) is the most common type of cancer in women. Among many risk factors of BC, mutations in BRCA2 gene were found to be the primary cause in 5-10% of cases. The majority of deleterious mutations are frameshift or nonsense mutations. Most of the reported BRCA2 mutations are protein truncating mutations. METHODS: The study aimed to describe the pattern of mutations including single nucleotide polymorphisms (SNPs) and variants of the BRCA2 (exon11) gene among Sudanese women patients diagnosed with BC. In this study a specific region of BRCA2 exon 11 was targeted using PCR and DNA sequencing. RESULTS: Early onset cases 25/45 (55.6%) were premenopausal women with a mean age of 36.6 years. Multiparity was more frequent within the study amounting to 30 cases (66.6%), with a mean parity of 4.1. Ductal type tumor was the predominant type detected in 22 cases (48.8%) among the reported histotypes. A heterozygous monoallelic nonsense mutation at nucleotide 3385 was found in four patients out of 9, where TTA codon was converted into the stop codon TGA. CONCLUSION: This study detected a monoallelic nonsense mutation in four Sudanese female patients diagnosed with early onset BC from different families. Further work is needed to demonstrate its usefulness in screening of BC.

Multiplicity of infection and genetic diversity of Plasmodium falciparum isolates from patients with uncomplicated and severe malaria in Gezira State, Sudan.

BACKGROUND: Multiplicity and genetic diversity of Plasmodium falciparum infection might play a role in determining the clinical outcome of malaria infection and could be a fair reflection of the disease transmission rate. This study investigated the genetic diversity of P. falciparum and multiplicity of infection in relation to the severity of malaria and age of patients in Gezira State, Sudan. METHODS: A cross-sectional health facilities-based survey was conducted in Gezira State, Sudan in January 2012. A total of 140 P. falciparum malaria patients diagnosed with microscopy and confirmed using nested PCR were recruited and classified into uncomplicated malaria and severe malaria states according to the standard WHO criteria. DNA was extracted and MSP1 and MSP2 allelic families were determined using nested PCR. RESULTS: The overall multiplicity of infection (MOI) was 2.25 and 2.30 and 2.15 for uncomplicated and severe malaria respectively. There were no statistically significant differences between uncomplicated and severe malaria (SM) patient groups in MOI with regard to MSP1, MSP2 and overall MOI (Mann-Whitney U-test; all P < 0.05). The predominant MSP1 allelic families were MAD20 for uncomplicated malaria and RO33 for severe malaria. The distribution of both FC27 and IC1/3D7 MSP2 allelic families were approximately the same across disease severity. One hundred and eleven P. falciparum isolates (81 %) consisted of multiple genotypes; 71/90 (78.9 %) in uncomplicated malaria and 40/50 (85.1 %) in severe malaria patient groups. Neither MSP1 nor MSP2 allelic families showed association with malaria severity. No statistically significant differences in multiplicity of infection were observed between different age groups. CONCLUSION: In this study the majority of P. falciparum isolates from uncomplicated and severe malaria patients consisted of multiple genotypes. Further molecular epidemiological studies delineate the link between P. falciparum genotype with the malaria phenotype in different regions are encouraged.
