<p><strong>Introduction:</strong> The term spondylodiscitis aims to describe any spinal infection. Medical treatment is the gold standard; nevertheless, surgical treatment can be indicated. The aim of this work was to study the epidemiological profile in a group of patients with spondylodiscitis surgically treated in the same medical institution between 1997 and 2013. <br /><strong>Material and Methods:</strong> Eighty five patients with spondylodiscitis were surgically treated in this period. The authors analysed clinical data and image studies for each patient.<br /><strong>Results:</strong> We treated 51 male and 34 female patients with an average age of 48 years old (min: 6 - max: 80). The lumbar spine was more often affected and <em>Mycobacterium tuberculosis</em> the most frequent pathogen. The number of cases through the years has been grossly stable, with a slight increase of dyscitis due to <em>Staphylococcus aureus</em> and decrease of the dyscitis without pathogen identification. Paravertebral abscess was identified in 39 patients and 17 had also neurological impairment, mostly located in the thoracic spine and with tuberculous aetheology. Immunosuppression was documented in 10 patients. <br /><strong>Discussion:</strong> In this epidemiologic study we found a tuberculous infection, male gender and young age predominance. Despite a relative constant number of patients operated over the years, pyogenic infections due to <em>Staphylococcus aureus</em> seems to be uprising. Paravertebral abscess and neurological impairment are important dyscitis complications, especially in tuberculous cases.<br /><strong>Conclusion:</strong> Spinal infections requiring surgical treatment are still an important clinical condition. <em>Mycobacterium tuberculosis</em> and <em>Staphylococcus aureus</em> represent the main pathogens with a growing incidence for the latest.</p>

The Mean

Background:Spondylodiscitis is an infective process of the disc and the two adjacent vertebrae. It is quite a rare disease accounting for 2–7% of all cases of septic osteomyelitis. These spinal infections touch commonly a single level, the lumbar spine being the most affected. Non-contiguous spine level involvement is seldom reported in the literature. This last group is for the most part imputable to granulomatous organisms [1,2].Objectives:Study the clinical, microbiological, radiological, therapeutic and evolutional characteristics of non-contiguous multi-levels spondylodiscitis.Methods:We conducted a retrospective descriptive study over twenty-one years in the Department of Rheumatology. The diagnosis of spondylodiscitis was based on combination of clinical, biological and radiological arguments.Results:Eight patients had non-contiguous multi-levels infectious spondylodiscitis. There were 6 men and 2 women. The mean age was 53.3±26.2 years. The mean delay from onset of symptoms to diagnosis was 134.6±77.6 days. Back pain was the most common symptom. All patients had spinal syndrome. The Signs of spinal cord compression were observed in 3 patients. C-reactive protein levels were elevated in 6 patients (mean: 56 ± 30.8 mg/L). Plain radiography, performed in all cases, showed pathological pictures in 7 patients. Magnetic resonance imaging was performed in 6 patients. Vertebral levels affected were thoracic / lumbar in 6 cases, cervical/thoracic in 1 case and cervical/lumbar in 1 case. The paravertebral abscess was associated to the disc involvement in 3 cases. Epiduritis was associated in 3 cases. Pathogens were isolated in all cases. Tuberculosis was the most common cause. The leading causative agents in non-tuberculosis spondylodiscitis were staphylococcus aureus, brucella and streptococcus B. Two microorganisms combined were found in two cases (mycobacterium tuberculosis associated to Escherichia coli in one case and mycobacterium tuberculosis associated to Brucella in another). Medical treatment was adapted to the microbial culture and the sensitivity profile of the etiological agent. After therapy, 7 patients had regression of symptoms and 1 patient had a permanent neurological impairment.Conclusion:Multilevel spondylodiscitis involving non-contiguous spine segments is rare. Although atypical organisms are generally held to be responsible, the common bacteria such as Streptococcus B or Staphylococcus aureus should not be overlooked.References:[1]Zimmerli W.

The Impact

Abstract Background People who inject drugs (PWID) are at risk for infectious complications of their injection practices, including Staphylococcus aureus (SA) bacteremia. Prolonged hospitalization is sometimes required; however, rates of discharges against medical advice (AMA) are elevated in this patient population. Inadequate control of pain and opioid withdrawal are commonly cited. Our aim was to assess the effectiveness of addiction medicine consultation for preventing AMA discharges. Methods We performed a retrospective chart review of adult PWID admitted to an urban hospital with SA bacteremia between August 2016 and May 2018. Demographics, HIV and HCV status, and presence or absence of addiction medicine consultation were recorded. We assessed whether discharges were planned or AMA; the number of hospitalizations at 30 days, 90 days, and 1 year from index admission; and death within one year. EpiInfo6 was used for data analysis. Results A total of 360 patients with SA bacteremia were reviewed. Of these, 101 reported intravenous opioid use at admission. Average age was 37 years, and 64% were male. HIV and HCV were present in 13% and 82% of patients, respectively. Addiction medicine was consulted on 29 patients. Of these, 4/29 (13.8%) left AMA, compared to 27/72 (37.5%) of patients without an addiction consult (RR = 0.3678 [95% CI = 0.1412 - 0.9583], p = 0.02). Patients receiving addiction medicine consultation averaged 0.17 readmissions within 30 days of their index admission, compared to 0.39 readmissions in the group without addiction medicine consult (p = 0.27). Readmissions at 90 days and 1 year were also lower but not statistically significant. At 1 year, 6 deaths were observed; 2 who had addiction medicine consultation and 4 who did not. Conclusion Consultation with an addiction medicine specialist significantly reduced the number of patients discharged AMA in a high-risk cohort of PWID presenting with SA bacteremia. Numerically fewer readmissions occurred after consultation, though this difference was not statistically significant. Mortality in both groups was low. There were high rates of HIV and HCV in this patient population, suggesting a particularly vulnerable patient population, which warrants further study.

Autophagy is a highly conserved and fundamental cellular process to maintain cellular homeostasis through recycling of defective organelles or proteins. In a response to intracellular pathogens, autophagy further acts as an innate immune response mechanism to eliminate pathogens. This review will discuss recent findings on autophagy as a reaction to intracellular pathogens, such as Salmonella typhimurium, Listeria monocytogenes, Mycobacterium tuberculosis, Staphylococcus aureus, and pathogenic Escherichia coli. Interestingly, while some of these bacteria have developed methods to use autophagy for their own benefit within the cell, others have developed fascinating mechanisms to evade recognition, to subvert the autophagic pathway, or to escape from autophagy.

Purpose This study is aimed to evaluate the clinical outcomes of surgical treatment for nonagenarian patients with colorectal cancer. Methods This retrospective single-center study included patients diagnosed with colorectal cancer at the age of ≥90 years between 2004 and 2018. Patient demographics were compared between the operation and nonoperation groups (NOG). Perioperative outcomes, histopathological outcomes, and postoperative complications were evaluated. Overall survival was analyzed using Kaplan-Meier methods and log-rank test. Results A total of 31 patients were included (16 men and 15 women), and the median age was 91 (range: 90‐96) years. The number of patients who underwent surgery and who received nonoperative management was 20 and 11, respectively. No statistical differences in baseline demographics were observed between both groups. None of these patients were treated with perioperative chemotherapy or radiotherapy. Surgery comprised 18 (90.0%) colectomies and 2 (10.0%) transanal excisions. Short-term (≤30 days) and long-term (31‐90 days) postoperative complications occurred in 7 (35.0%) and 4 (20.0%) patients, respectively. No complications needed reoperation, such as anastomosis leakage or bleeding. No postoperative mortality occurred within 30 days: 90-day postoperative mortality occurred in two patients (10.0%), respectively. The median overall survival of the operation group was 31.6 (95% confidence interval: 26.7‐36.5) and that of NOG was 12.5 months (95% CI: 2.4‐22.6) ( P = 0.012). Conclusion Surgical treatment can be considered in carefully selected nonagenarian patients with colorectal cancer in terms of acceptable postoperative morbidity, with better overall survival than the nonsurgical treatment.

Представлены результаты проспективного обследования 80 больных ГКБ №7 с бактериемией с октября 2019 года по февраль 2021 года из различных отделений госпиталя. Производилась оценки показателей маркеров сепсиса - пресепсина, прокальцитонина и С-реактивного белка (СРБ) в крови больных в динамике эмпирической терапии антимикробными препаратами (АМП). Наибольшее число больных с выявленной бактериемией находилось в отделении ОАРИТ - 39 пациентов, у 25 из них был диагностирован сепсис по шкале СЕПСИС III, вызванный известными патогенами Staphylococcus aureus (46,6%) и Escherichia coli (36,6%). Для эмпирического лечения применялись различные антибиотики: ампенициллин, амикацин, меропенем, цефотаксим, метрид, ципрофлоксацин, ципрокс, цефлокс, цефазолин, цефтриаксон, левофлоксацин. Уровни прокальцитонина составляют для больных с клиническими изолятами E. coli 20,8±3,1нг/мл, а для изолятов St. aureus 15,7±1,8 нг/мл. После терапии АМП наблюдается значительное снижение показателей до 1,43±0,6 и 2,3±0,9 нг/мл., что позволяет признать эффективность эмпирической антибиотикотерапии при инфекциях кровотока. Высокая чувствительность клинических изолятов Escherichia coli отмечена к препаратам группы карбапенемов - имипенему и меропенему (90,9%), низкая к эртапенему (72,7%). 100% чувствительность все изоляты показали по отношению к АМП из группы глицилциклинов - тигециклину, который структурно сходен с тетрациклинами. Высокой резистеностью клинические изоляты Staphylococcus aureus обладают к пенициллину (92,9%), липопептиду природного происхождения даптомицину (85,8%) и препарату из группы линкозамидов - клиндамицину (64,3%). The results of a prospective examination of 80 patients with bacteremia from October 2019 to February 2021 from various departments of the hospital are presented. The largest number of patients with detected bacteremia were in the OARIT department - 39 patients, 25 of them were diagnosed with sepsis according to the SEPSIS III scale, caused by known pathogens Staphylococcus aureus (46.6%) and Escherichia coli (36.6%). For empirical treatment, various antibiotics were used: ampenicillin, amikacin, meropenem, cefotaxime, metrid, ciprofloxacin, ciprox, ceflox, cefazolin, ceftriaxone, levofloxacin. Procalcitonin levels for patients with clinical E. coli isolates are 20.8 ± 3.1 ng / ml, and for St. aureus 15.7 ± 1.8 ng / ml. After AMP therapy, there is a significant decrease in indicators to 1.43 ± 0.6 and 2.3 ± 0.9 ng / ml, which makes it possible to recognize the effectiveness of empiric antibiotic therapy for bloodstream infections. High sensitivity of clinical isolates of Escherichia coli was noted to drugs of the carbapenem group - imipenem and meropenem (90.9%), low to ertapenem (72.7%). All isolates showed 100% sensitivity to AMPs from the glycylcycline group - tigecycline, which is structurally similar to tetracyclines. Clinical isolates of Staphylococcus aureus are highly resistant to penicillin (92.9%), natural lipopeptide daptomycin (85.8%), and a drug from the lincosamide group - clindamycin (64.3%).

Structural Simplicity

Due to the prevalence of thioamides in antibacterial compounds, we chose to convert the amide in the antitubercular compound 2-(decylsulfonyl)acetamide to a thioamide using Lawesson’s reagent to study its activity against a range of microorganisms. This derivative (8) had significantly diminished activity against tuberculosis but slightly better activity than the parent compound against the Gram positive species Staphylococcus aureus. This activity against a second major pathogen is remarkable considering the structural simplicity of these compounds.

Introduction: Beijing family strains of Mycobacterium tuberculosis are associated with multidrug-resistance. Although strains of the Lisboa family are the most common among multidrug-resistant and extensively drug-resistant patients in the region, several studies have reported the presence of the Beijing family. However, the features of patients from whom they were isolated, are not yet known.Material and Methods: Retrospective study involving 104 multidrug-resistant and extensively drug-resistant strains of Mycobacterium tuberculosis, from the same number of patients, isolated and genotyped between 1993 and 2015 in Lisbon. We assessed the prevalence of strains of both families and the epidemiologic and clinical features of those infected with Beijing family strains.Results: Seventy-four strains (71.2%) belonged to the Lisboa family, 25 (24.0%) showed a unique genotypic pattern and five (4.8%) belonged to the Beijing family, the latter identified after 2009. Those infected with Beijing family strains were angolan (n = 1), ukrainian (n = 2) and portuguese (n = 2), mainly young-aged and, four of five immunocompetent and with no past history of tuberculosis. All had multidrug-resistant tuberculosis. We did not find any distinctive clinical or radiological features, neither a predominant resistance pattern. Cure rate was high (four patients).Discussion: Although the number of infected patients with Beijing strains was small, it suggests an important proportion of primary tuberculosis, a potential for transmission in the community but also a better clinical outcome when compared to other reported strains, such as W-Beijing and Lisboa.Conclusion: Although Lisboa family strains account for most of the multidrug and extensively drug-resistant tuberculosis cases in Lisbon area, Beijing strains are transmitted in the city and might change the local characteristics of the epidemics.
