BACKGROUND: /Objectives: This study aimed to evaluate the frequency, clinical impact, and risk factors of post-pancreatectomy acute pancreatitis (PPAP) after pancreatoduodenectomy (PD) according to the definition proposed by the International Study Group for Pancreatic Surgery (ISGPS).
METHODS: patients undergoing PD between 2010 and 2021 were retrospectively analyzed. PPAP was defined according to the ISGPS criteria, including elevated serum amylase for 48 h and concurring pancreatitis alterations on a CT scan.
RESULTS: 272 patients were finally included in the study. PPAP occurred in 40 (14.7 %) patients, and it was significantly related to higher rates of clinically-relevant postoperative pancreatic fistula (CR-POPF) (p < 0.001), post-pancreatectomy hemorrhage (PPH) (p < 0.001) and major complications (Clavien-Dindo ≥ 3a) (p < 0.001). Moreover, PPAP in the absence of CR-POPF (n = 18) was significantly related to longer hospital stay (p < 0.001), PPH (p < 0.001), major complications (Clavien-Dindo≥ 3a, p = 0.001) and higher intensive care unit costs (p = 0.029) compared to patients not developing PPAP. In the univariable and multivariable analysis, the duct size (p = 0.004) and high-risk pathologies (p = 0.004) but not intraoperative bleeding (p = 0.066) represented independent risk factors for PPAP. In the same analysis, patients receiving a bridging therapy with low molecular-weight heparin showed significantly lower rates of PPAP (p = 0.045).
CONCLUSIONS: PPAP represents a relevant complication after PD. Its risk factors are similar to those for CR-POPF, while anticoagulants could represent a possible prevention strategy.

BACKGROUND: Pharmacists have been co-located in general practice teams to support the quality use of medicines and optimise patient health outcomes. Evidence of the impact of pharmacist-led activities in Australian general practices is sparse.
OBJECTIVE: This study aimed to evaluate the potential outcomes of pharmacist-led activities in Australian general practices.
METHODS: A prospective observational study was conducted in eight general practices in the Australian Capital Territory, where each general practice employed a pharmacist on a part-time basis for 18 months. A recommended, but flexible, list of activities was provided for pharmacists. Descriptive information on general practice pharmacist-led activities, collected with an online diary, was analysed. The potential clinical, economic, and organisational impact of pharmacist-led clinical activities was evaluated using the CLinical Economic Organisational (CLEO) tool, with a modified economic dimension.
RESULTS: Nine pharmacists reported 4290 activities over 3918.5 work hours in general practice. Medication management services were the primary clinical activity of pharmacists. In medication reviews, 75% of the pharmacists\' recommendations were fully accepted by general practitioners. Conducting clinical audits, updating patients\' medical records, and providing information to patients and staff were other major activities of pharmacists. Of 2419 clinical activities, around 50% had the potential for a moderate or major positive clinical impact on patients. Sixty-three per cent of activities had the potential to decrease healthcare costs. Almost all the pharmacist-led clinical activities had a positive organisational impact.
CONCLUSIONS: Most pharmacist-led clinical activities in general practice had the potential for a positive impact on patients and reduction in healthcare costs, supporting the expansion of this model in Australia.

Invasive aspergillosis (IA) by a triazole-resistant Aspergillus fumigatus is associated with high mortality. Real-time resistance detection will result in earlier initiation of appropriate therapy.
In a prospective study, we evaluated the clinical value of the AsperGenius polymerase chain reaction (PCR) assay in hematology patients from 12 centers. This PCR assay detects the most frequent cyp51A mutations in A. fumigatus conferring azole resistance. Patients were included when a computed tomography scan showed a pulmonary infiltrate and bronchoalveolar fluid (BALf) sampling was performed. The primary end point was antifungal treatment failure in patients with azole-resistant IA.
Of 323 patients enrolled, complete mycological and radiological information was available for 276 (94%), and probable IA was diagnosed in 99/276 (36%). Sufficient BALf for PCR testing was available for 293/323 (91%). Aspergillus DNA was detected in 116/293 (40%) and A. fumigatus DNA in 89/293 (30%). The resistance PCR was conclusive in 58/89 (65%) and resistance detected in 8/58 (14%). Two had a mixed azole-susceptible/azole-resistant infection. In the 6 remaining patients, treatment failure was observed in 1. Galactomannan positivity was associated with mortality (P = .004) while an isolated positive Aspergillus PCR was not (P = .83).
Real-time PCR-based resistance testing may help to limit the clinical impact of triazole resistance. In contrast, the clinical impact of an isolated positive Aspergillus PCR on BALf seems limited. The interpretation of the EORTC/MSGERC PCR criterion for BALf may need further specification (eg, minimum cycle threshold value and/or PCR positive on >1 BALf sample).

During the dispensing process of medical orders (MOs), community pharmacists (CPs) can manage drug-related problems (DRPs) by performing pharmacist interventions (PIs). There is little evidence that the PI rate is higher with MOs from hospitals (MOHs) than ambulatory (MOAs) settings, and their impact on the patient and community pharmacy is unknown. The primary objective of this study was to compare the MOH and MOA PI rates. The secondary objective was to describe PIs and their clinical and organizational impacts on patient and community pharmacy workflow. A total of 120 CPs participated in a prospective study. Each CP included 10 MOH and 10 MOA between January and June 2020. DRP and PI description and clinical and organizational impacts between MOH and MOA were assessed and compared. We analyzed 2325 MOs. PIs were significantly more frequent in MOH than in MOA (9.7% versus 4.7%; p < 0.001). The most reported PI was the difficulty of contacting hospital prescribers (n = 45; 52.2%). MOHs were associated with a longer dispensing process time and a greater impact on patient pathway and community pharmacy workflow than MOAs. Lack of communication between hospital and primary care settings partly explains the results. Implementation of clinical pharmacy activities at patient discharge could alleviate these impacts.

Objective: To analyze the clinical and economic impact of community-onset urinary tract infections (UTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae requiring hospitalization. Methods: A retrospective cohort study that included all adults with a UTI caused by K. pneumoniae that were admitted to a tertiary care hospital in Barcelona, Spain, between 2011 and 2015. Demographic, clinical, and economic data were analyzed. Results: One hundred and seventy-three episodes of UTIs caused by K. pneumoniae were studied; 112 were non-ESBL-producing and 61 were ESBL-producing. Multivariate analysis identified ESBL production, acute confusional state associated with UTI, shock, and the time taken to obtain adequate treatment as risk factors for clinical failure during the first seven days. An economic analysis showed differences between ESBL-producing and non-ESBL-producing K. pneumoniae for the total cost of hospitalization per episode (mean EUR 6718 vs EUR 3688, respectively). Multivariate analysis of the higher costs of UTI episodes found statistically significant differences for ESBL production and the time taken to obtain adequate treatment. Conclusion: UTIs caused by ESBL-producing K. pneumoniae requiring hospitalization and the time taken to obtain adequate antimicrobial therapy are associated with worse clinical and economic outcomes.

OBJECTIVE: The aim of this multicenter prospective study was to compare the sensitivity of 18F-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) with that of 67Ga single photon emission computed tomography (SPECT) for the identification of the site of greatest importance for the final diagnosis of the cause of fever of unknown origin (FUO).
METHODS: The study participants consisted of patients with an axillary temperature ≥ 38.0 °C on ≥ 2 occasions within 1 week, with repeated episodes for ≥ 2 weeks prior to providing consent, and whose final diagnosis after undergoing specific examinations, including a chest-to-abdomen CT scan, was uncertain. All the patients underwent FDG-PET/CT imaging first, followed by 67Ga-SPECT imaging within 3 days. The results of the FDG-PET/CT and 67Ga-SPECT examinations were reviewed by the central image interpretation committee (CIIC), which was blinded to all other clinical information. The sensitivities of FDG-PET/CT and 67Ga-SPECT were then evaluated with regard to identifying the site of greatest importance for a final diagnosis of the cause of the fever as decided by the patient\'s attending physician. The clinical impacts (four grades) of FDG-PET/CT and 67Ga-SPECT on the final diagnosis were evaluated.
RESULTS: A total of 149 subjects were enrolled in this study between October 2014 and September 2017. No adverse events were identified among the enrolled subjects. Twenty-one subjects were excluded from the study because of deviations from the study protocol. Among the 128 remaining subjects, a final diagnosis of the disease leading to the appearance of FUO was made for 92 (71.9%) subjects. The final diagnoses in these 92 cases were classified into four groups: noninfectious inflammatory disease (52 cases); infectious disease (31 cases), malignancy (six cases); and other (three cases). These 92 subjects were eligible for inclusion in the study\'s analysis, but one case did not meet the PET/CT image acquisition criteria; thus, PET/CT results were analyzed for 91 cases. According to the patient-based assessments, the sensitivity of FDG-PET/CT (45%, 95% CI 33.1-58.2%) was significantly higher than that for 67Ga-SPECT (25%, 95% CI 15.5-37.5%) (P = 0.0029). The clinical impact of FDG-PET/CT (91%) was also significantly higher than that for 67Ga-SPECT (57%, P < 0.001).
CONCLUSIONS: FDG-PET/CT showed a superior sensitivity to 67Ga-SPECT for the identification of the site of greatest importance for the final diagnosis of the cause of FUO.

OBJECTIVE: To investigate the clinical impact of FDG-PET/CT for staging and treatment planning in high-risk primary breast cancer.
METHODS: Women with high-risk primary breast cancer were enrolled between September 2017 and August 2019 at Odense University Hospital, Denmark. Conventional mammography with/without MRI was performed before staging by FDG-PET/CT. We studied the accuracy of FDG-PET/CT for the detection of distant metastases, the effect on the change of treatment, and the prevalence of incidental findings. Biopsy and follow-up were used as a reference standard for the accuracy analysis.
RESULTS: Of 103 women, 24 (23%) were diagnosed with distant metastases by FDG-PET/CT. Among these, breast surgery was omitted in 18 and could have been spared in six. Another sixteen (16%) patients were upstaged to more advanced loco-regional disease, leading to more extensive radiotherapy. Sensitivity and specificity for diagnosing distant metastases were 1.00 (95% confidence interval: 0.86-1.00) and 0.95 (0.88-0.99), respectively. Twenty-nine incidental findings were detected in 24 women (23%), leading to further examinations in 22 and diagnosis of eight (8/22, 36%) synchronous diseases: cancer (n = 4), thyroiditis (n = 2), aorta aneurysm (n = 1), and meningioma (n = 1).
CONCLUSIONS: FDG-PET/CT had a substantial impact on staging and change of treatment in women with high-risk primary breast cancer, and further examination of incidental findings was considered clinically relevant. Our findings suggest that FDG-PET/CT should be considered for primary staging in high-risk primary breast cancer to improve treatment planning.

This study aimed to describe the effect of initial antifungal therapy on patient mortality and to detail the current distribution and resistance patterns of Candida spp. among patients with candidaemia. A prospective observational study was performed among consecutive patients with candidaemia from 10 Turkish medical centres between January 2015 and November 2018. The primary outcome was 10-day mortality. Species were identified using MALDI-TOF/MS. A total of 342 patients with candidaemia were included, of which 175 (51.2%) were male and 68 (19.9%) were aged <18 years. The most common species were Candida albicans (47.4%), Candida parapsilosis (26.6%), Candida tropicalis (9.6%) and Candida glabrata (7.6%). Among all Candida spp., the 10-day case fatality rate (CFR) was 32.2%. The CFR was highest in patients with C. albicans (57.3%) and lowest in patients with C. parapsilosis (21.8%). The resistance rate to fluconazole was 13% in C. parapsilosis, with no significant effect on mortality. No resistance to echinocandins was detected. In the multivariate analysis, being in the ICU [OR = 2.1 (95% CI 1.32-3.57); P = 0.002], renal failure [OR = 2.4 (1.41-3.97); P = 0.001], total parenteral nutrition [OR = 2 (1.22-3.47); P = 0.006], C. albicans infection [OR = 1.7 (1.06-2.82); P = 0.027] and echinocandin as primary agent [OR = 0.6 (0.36-0.99); P = 0.047] were significantly associated with mortality. Candidaemia is a deadly infection. Fluconazole resistance is emerging, although it was not significantly related to mortality. Using an echinocandin as the primary agent could be life-saving.

Most comparative clinical trials are designed to assess the treatment effect for efficacy endpoints, with less emphasis on the analysis of safety outcomes. However, an extensive analysis of safety data could demonstrate beneficial results in terms of effectiveness by reducing serious adverse events (SAEs), and their unfavourable clinical impact on the study population. We aimed to conduct an exploratory analysis of the CHInese Medicine Neuroaid Efficacy on Stroke recovery (CHIMES) study safety database comparing the frequency of SAEs and their clinical impacts among subjects having received MLC601 or placebo during the first 3 months post-stroke.
Analyses were performed by using the safety database of the multicentre, randomised, double-blind, placebo-controlled CHIMES study of 3 months of NeuroAiD versus placebo in subjects with acute ischaemic stroke of intermediate severity in the preceding 72 h. SAEs as reported by investigators at any time-point during the 3-month study were analysed on their frequency and that of any of their outcomes (death, and life threatening, new and/or prolonged hospitalisation, disability, and medical importance, in surviving subjects), as well as their time to onset and resolution.
Of the 1,099 subjects in the CHIMES study, 1,087 were included in the safety analysis (MLC601 = 542) and (placebo = 545); the 12 who did not receive study treatment were excluded. There was a total of 135 subjects with SAEs (MLC601 = 60, placebo = 75). At baseline, overall, subjects with SAEs were older and had lower MMSE score. In the MLC601 group, they had higher NIHSS score, and more frequently a history of ischaemic heart disease and hyperlipidaemia. The number of SAEs per subjects was statistically significantly lower in the MLC601 group than placebo one, especially for subjects with ≥2 SAEs (6.7 vs. 29.3%; p < 0.001). This benefit was seen throughout the study period and during the initial hospitalisation. The main clinical impact of SAEs was an increase in hospitalisation time, reduced in the MLC601 arm with the rate of subjects hospitalised for a prolonged period being significantly threefold lower in surviving subjects (1.1 vs. 3.7%; p < 0.01).
This post hoc analysis of SAEs from the CHIMES study database shows that subjects receiving a 3-month course of MLC601 experienced fewer SAEs, with lower rates of harmful clinical impacts, especially in terms of hospitalisation duration. These findings could translate to a benefit in terms of reduction of both healthcare burden and additional medical costs.

BACKGROUND: Point-of-care ultrasound (POCUS) is a tool in increasing use, but there is still a lack of basics for its routine use and evidence of its impact in intensive care.
OBJECTIVE: To measure the impact of POCUS on resource utilization, diagnostic accuracy, and clinical management in medical-surgical intensive care units (ICUs).
METHODS: Prospective, controlled study, in two polyvalent ICUs. The patients were randomly assigned to POCUS or control group.
METHODS: POCUS patients received systematic ultrasound examination of optic nerve, lung/pleura, heart, abdomen, and venous system, performed at the bedside by trained intensivists. Control patients were treated by critical care specialists who do not perform ultrasound in their clinical practice.
RESULTS: We included 80 patients, 40 per group. There were no significant differences in age, sex, APACHE II score, or admission diagnosis. POCUS group used fewer resources per patient in the first 5 days of hospitalization: chest radiography (2.6 ± 2.0 vs 4.1 ± 3.5, P = 0.01), additional ultrasound evaluations performed by a radiology specialist (0.6 ± 0.7 vs 1.1 ± 0.7, P = 0.002), and computed tomography studies (0.5 ± 0.6 vs 0.9 ± 0.7, P = 0.007). Time to perform any requested ultrasound evaluation after ICU admission was 2.1 ± 1.6 h versus 7.7 ± 6.7 h (P = 0.001). Systematic ultrasound evaluation led to better characterization of ICU admission diagnosis in 14 (35%) patients and change in clinical management in 24 (60%). POCUS group had lower fluid balance at 48 and 96 h after admission (P = 0.01) and spent less time mechanically ventilated (5.1 ± 5.7 days vs 8.8 ± 9.4, P = 0.03).
CONCLUSIONS: Systematic application of POCUS may decrease utilization of conventional diagnostic imaging resources and time of mechanical ventilation, and facilitate meticulous intravenous fluid administration in critically ill patients during the first week of stay in the ICU.
