Antimicrobial Susceptibility Profiles of Klebsiella pneumoniae Strains Collected from Clinical Samples in a Hospital in Southern Italy.

Infections caused by antibiotic-resistant bacteria represent a serious threat to global public health. Recently, due to its increased resistance to carbapenems and ß-lactams, Klebsiella pneumoniae has become one of the main causes of septicemia, pneumonia, and urinary tract infections. It is crucial to take immediate action and implement effective measures to prevent further spread of this issue. This study aims to report the prevalence and antibiotic resistance rates of K. pneumoniae strains isolated from clinical specimens from 2015 to 2020 at the University Hospital of Salerno, Italy. More than 3,800 isolates were collected from urine cultures, blood cultures, respiratory samples, and others. K. pneumoniae isolates showed broad resistance to penicillin and cephalosporins, and increased susceptibility to fosfomycin and gentamicin. Extended spectrum beta-lactamase (ESBL) isolates accounted for 20-22%. A high percentage of strains tested were resistant to carbapenems, with an average of 40% to meropenem and 44% to ertapenem. The production of ESBLs and resistance to carbapenems is one of the major public health problems. Constant monitoring of drug-resistant isolates is crucial for developing practical approaches in implementing antimicrobial therapy and reducing the spread of K. pneumoniae in nosocomial environments.

Can esophageal symptoms be associated with sleep disorders in esophageal rare diseases?. A prospective case-control study across achalasia, eosinophilic esophagitis and gastroesophageal reflux disease.

BACKGROUND: The association between sleep disorders and gastroesophageal reflux disease (GERD) has been the subject of several studies; however, quality of sleep has been under investigated in adult patients with eosinophilic esophagitis (EoE) and achalasia (Ach). This study aims to evaluate the prevalence of sleep disturbances in patients with EoE and Ach compared to GERD patients and their associations with esophageal symptoms. METHODS: Thirty Ach patients and 20 EoE patients were consecutively enrolled and compared to a control group of 46 GERD patients. All patients underwent a standardized questionnaire investigating the intensity-frequency scores (from 0 to 6) of esophageal symptoms, Pittsburgh Sleep Quality Index (PSQI) questionnaire to assess sleep quality, a SF-36 survey to investigate health-related quality of life (both physical (PCS) and mental (MCS) component scales), Beck Depression Inventory-II (BDI-II) and State Trait Anxiety Inventory (STAI) to assess the presence of depression and anxiety. RESULTS: The prevalence of sleep disturbances was 66.7% in Ach, 50% in EoE, and 60% in GERD patients (P=0.5). PCS and MCS significantly correlated with depression and anxiety levels. Ach patients showed significantly higher intensity-frequency scores of dysphagia for solids (Scheffè P<0.001) and liquids (Scheffè P<0.001) than EoE and GERD patients. No differences were found in the intensity-frequency scores of the esophageal symptoms among the three groups. There was a significant association between worst quality of sleep and higher intensity-frequency scores of regurgitation. CONCLUSIONS: Sleep disturbances are common with Ach and EoE, similar to GERD patients. Moreover, there is a significant association between regurgitation, a typical GERD symptom, and poor quality of sleep, independent from diagnosis.

Scale of Assessment of Caregiver Care Burden of People With Dementia: A Systematic Review of Literature.

Cases of dementia have increased significantly in recent years. The family represents the main cornerstone of assistance to the elderly suffering from dementia, in particular the caregiver. Family members who take on the role of caregiver are subjected to physical, psychological, emotional, social and financial stress, which can be conceptualised with the term "burden". The aim of this study was to investigate which tools are best suited to measure the type of burden based on the type of dementia for each caregiver. A literature search was undertaken in MEDLINE, CINHAL and The Cochrane Database in September 2022, including articles from the last 20 years and using a combination of keywords and defined inclusion criteria. This literature review has been performed according to the PRISMA statement. From a total of 116 articles regarding the use of burden rating scales for caregivers, 18 scales were selected. The review provides a useful overview of burden assessment scales, classified into three categories, one-dimensional, multidimensional, or distinct concept with a subjective and objective component, in order to adopt appropriate strategies to assess caregiver burden and improve the quality of their health, both in the community and in hospitals. Indeed, the domestic context is the most studied as there is a greater risk of developing the burden of the caregiver: for this reason, some scales include the assessment of both the caregiver and the patient receiving treatment.

Microbial Air Contamination in a Dental Setting Environment and Ultrasonic Scaling in Periodontally Healthy Subjects: An Observational Study.

The risk of microbial air contamination in a dental setting, especially during aerosol-generating dental procedures (AGDPs), has long been recognized, becoming even more relevant during the COVID-19 pandemic. However, individual pathogens were rarely studied, and microbial loads were measured heterogeneously, often using low-sensitivity methods. Therefore, the present study aimed to assess microbial air contamination in the dental environment, identify the microorganisms involved, and determine their count by active air sampling at the beginning (T0), during (T1), and at the end (T2) of ultrasonic scaling in systemically and periodontally healthy subjects. Air microbial contamination was detected at T0 in all samples, regardless of whether the sample was collected from patients treated first or later; predominantly Gram-positive bacteria, including Staphylococcus and Bacillus spp. and a minority of fungi, were identified. The number of bacterial colonies at T1 was higher, although the species found were similar to that found during the T0 sampling, whereby Gram-positive bacteria, mainly Streptococcus spp., were identified. Air samples collected at T2 showed a decrease in bacterial load compared to the previous sampling. Further research should investigate the levels and patterns of the microbial contamination of air, people, and the environment in dental settings via ultrasonic scaling and other AGDPs and identify the microorganisms involved to perform the procedure- and patient-related risk assessment and provide appropriate recommendations for aerosol infection control.
