Type 2 diabetes mellitus (DM) is a chronic metabolic disorder posing multifaceted challenges to global public health. Among its numerous complications, infected diabetic foot ulcers (IDFUs) represent a particularly debilitating consequence. Beyond cardiovascular implications, there is an emerging understanding of the interconnectedness among IDFUs, neuropathy, atherosclerosis, and dyslipidemia. IDFUs, peripheral neuropathy, and atherosclerosis share common risk factors and mechanistic pathways. The primary objective of this study was to characterize the lipid profiles in DM patients with IDFUs, comparing them with DM patients without foot ulcers, and with a control group of healthy subjects. The secondary objectives included evaluating apolipoprotein E (ApoE) levels across these study groups and comparing lipid profiles within IDFU subgroups. A total of 160 patients were assessed for this study. After applying exclusion criteria, 140 participants were included, divided into three groups: Group IDFU (80 patients with IDFUs), Group DM (32 patients with DM but no foot ulcers), and Group Controls (28 healthy controls). Compared to Group DM, Group IDFU demonstrated lower levels of high-density lipoprotein cholesterol (HDL-C) (30.9 ± 12.6 mg/dL vs. 40.8 ± 16.6 mg/dL, p = 0.002), but improved levels of ApoE (160.9 ± 68.4 mg/dL vs. 197.2 ± 69.6 mg/dL, p = 0.01), triglycerides (TG) (126.9 ± 56.2 mg/dL vs. 165.8 ± 79.0 mg/dL, p = 0.004), low-density lipoprotein cholesterol (LDL-C) (84.2 ± 32.3 mg/dL vs. 92.3 ± 39.3 mg/dL, p = 0.1), and total cholesterol (133.6 ± 43 mg/dL vs. 164.6 ± 44.4 mg/dL, p = 0.002). The IDFU patients exhibit improved lipid profiles, excepting HDL-C, which is unusual because IDFU follows complications related to dyslipidemia for DM patients. Anemia, impaired renal function, and elevated TG levels were identified as biomarkers for mortality among patients with IDFUs. The data suggest that a lower level of HDL-C and an improved lipid profile may indicate a systemic end-stage disease manifestation in DM patients with IDFUs.

Cystic echinococcosis (CE) is a neglected parasitic disease caused by the tapeworm Echinococcus granulosus. The aim of this study was to assess the epidemiological features of human cystic echinococcosis in patients from Western Romania. We retrospectively investigated the medical records of patients hospitalized with CE between 1 January 2007 and 1 September 2022. A total of 366 patients (range 18–90 years) were recorded. The number of hospitalized individuals was higher in patients aged 50–59 years (83/366, 22.7%), in females (194/366, 53%), and in residents of rural areas (225/366, 61.5%). The liver was the most common localization of the cysts (302/366, 82.5%). Ninety-eight patients (26.8%) presented complications, including biliary fistula, allergies, and infection of the cyst. Patients with complications had a longer mean hospital stay (15.7 ± 8.3 days) compared to patients without complications (11.5 ± 7.3 days) (p < 0.001). The results of this study revealed that patients diagnosed with CE required hospitalization and extended medical care, indicating that this zoonotic disease remains a significant public health problem in Western Romania. Public health authorities should enhance CE surveillance by implementing control programs and mandatory notification of new cases.

Toxoplasma gondii, a zoonotic protozoan parasite, has the capacity to infect the fetus if the pregnant woman primarily acquires the infection during pregnancy. We evaluated the prevalence of T. gondii IgG, IgM and IgA antibodies in women of reproductive age residing in Western Romania. We also assessed the value of adding a T. gondii IgA test to the serologic panel for the diagnosis of toxoplasmosis, including the detection of a recently acquired infection. Serologic testing to demonstrate the presence of T. gondii IgG antibodies was conducted in 1317 females aged 15–45 years. T. gondii IgM and IgA antibody tests were performed in those with detectable IgG antibodies and IgG avidity test was performed if IgM and/or IgA screening test results were positive. T. gondii IgG were detected in 607 (46.09%; 95%CI: 43.41–48.79) of 1317 study participants and IgG seroprevalence tended to increase with age from 35.44% (95%CI: 29.89–41.30) in age group 15–24 years to 62.85% (95%CI: 56.57–68.82) in age group 35–45 years, showing a significant age-associated increase (p < 0.001). Of the 607 persons with detectable T. gondii IgG antibodies, T. gondii IgM antibodies were demonstrated in 8.90% (95%CI: 6.88–11.43), T. gondii IgA in 1.65% (95%CI: 0.90–3.01) and both T. gondii IgM and IgA in 0.99% (95%CI: 0.45–2.14). The prevalence of IgA antibodies tended to decrease with increasing avidity, from 75% (95%CI: 19.41–99.37) in samples with low avidity to 11.76% (95%CI: 4.44–23.87) in those with high avidity (p = 0.01). Of the study participants who were positive for both T. gondii IgM and IgA antibodies, 66.67% had low or equivocal IgG avidity test results compared to 6.25% who tested positive for IgM, were negative for IgA and in whom low or equivocal IgG avidity test results were noted (p = 0.001). This study indicates that in Western Romania, T. gondii IgG seroprevalence is high in females of reproductive age and T. gondii IgA antibodies may be rarely detected during a serologic screening. However, in individuals with demonstrable T. gondii IgG and IgM antibodies, testing for T. gondii IgA may improve the rate for the detection of a recently acquired toxoplasmosis.

Raoultella planticola is a Gram-negative bacterium rarely involved in urinary tract infections. The patient was an 80-year-old woman with several associated diseases who presented to the hospital with fever and dysuria. Raoultella planticola was identified to be the causative agent of the urinary tract infection. Antibacterial treatment led to a full recovery within 7 days. This report highlights the presence of a rare pathogen as a causative agent in the case of a urinary tract infection and also the importance of using multiple methods in order to identify bacteria and to establish the diagnosis.

Cystic echinococcosis (CE) is a serious health problem in many countries worldwide, including in Romania, because of the high infection rates in both humans and animals. We retrospectively assessed the demographic and epidemiological features of CE in children and adults hospitalized in Western Romania between 2007–2022. Analyzed data were collected from the hospitals’ medical records. This research involved 426 subjects (3–90 years): 60 (14.1%) children and 366 (85.9%) adults. A decreasing trend in the number of cases was noted during the analyzed period (p = 0.004). Multiple-organ involvement was reported in 16.7% of the children and in 6.3% of the adults (p = 0.005). The liver was the most commonly affected organ. The rate of lung involvement was higher in children (25%) than in adults (13.1%) (p = 0.02). Most of the patients had one hospital presentation (74.9%). Multiple hospitalizations were reported in 40% of the children and 22.7% of the adults (p = 0.004). CE is a severe zoonotic disease that impacts individuals of all ages. Despite the decline in cases, CE remains a public-health problem in Western Romania. Health programs that target risk factors and control measures should be implemented to stop the parasite’s spread and maintain the trend toward reduced numbers of CE cases.

Vitamin D, a steroid hormone synthesized primarily in the skin upon exposure to ultraviolet light, is widely deficient across global populations. This study aimed to fill the data gap in Western Romania by measuring 25-hydroxy-vitamin D levels in a cohort of 7141 from Arad County. It was observed that women, younger adults (18–29 years), and older adults (70–79 years) had notably lower vitamin D levels compared to the average population. Additionally, there was a rise in vitamin D levels over the four-year span of 2018–2022, coinciding with the COVID-19 pandemic. Our research provides fresh data on those most susceptible to vitamin D deficiency and lays the groundwork for educational campaigns on vitamin D supplementation benefits.
