A survey of Australian public opinion on using comorbidity to triage intensive care patients in a pandemic.

ObjectivesThis study aimed to determine which method to triage intensive care patients using chronic comorbidity in a pandemic was perceived to be the fairest by the general public. Secondary objectives were to determine whether the public perceived it fair to provide preferential intensive care triage to vulnerable or disadvantaged people, and frontline healthcare workers.MethodsA postal survey of 2000 registered voters randomly selected from the Australian Electoral Commission electoral roll was performed. The main outcome measures were respondents' fairness rating of four hypothetical intensive care triage methods that assess comorbidity (chronic medical conditions, long-term survival, function and frailty); and respondents' fairness rating of providing preferential triage to vulnerable or disadvantaged people, and frontline healthcare workers.ResultsThe proportion of respondents who considered it fair to triage based on chronic medical conditions, long-term survival, function and frailty, was 52.1, 56.1, 65.0 and 62.4%, respectively. The proportion of respondents who considered it unfair to triage based on these four comorbidities was 31.9, 30.9, 23.8 and 23.2%, respectively. More respondents considered it unfair to preferentially triage vulnerable or disadvantaged people, than fair (41.8% versus 21.2%). More respondents considered it fair to preferentially triage frontline healthcare workers, than unfair (44.2% versus 30.0%).ConclusionRespondents in this survey perceived all four hypothetical methods to triage intensive care patients based on comorbidity in a pandemic disaster to be fair. However, the sizable minority who consider this to be unfair indicates that these triage methods could encounter significant opposition if they were to be enacted in health policy.

Insights into the microbiological and virulence characteristics of bacteria in orthopaedic implant infections: A study from Pakistan.

The exponential increase in the prevalence of multidrug resistant bacteria has resulted in limiting surgical treatment options globally, potentially causing biofilm-related complications, implant failure, and severe consequences. This study aims to isolate and characterize bacteria from post-surgical orthopaedic implant infections and screening for multiple antibiotic resistance. A cross-sectional study was conducted, involving isolation of forty-four dominant pathogenic bacterial isolates from 16 infected implant samples from across Islamabad and Rawalpindi. Out of forty-four, 38% cocci and 61% bacilli were obtained. Approximately 90% of isolates showed multiple antibiotic resistance (MAR) index of more than 0.2. Eleven strains were identified via 16S rRNA gene sequencing as Pseudomonas aeruginosa, Bacillus spp., Planococcus chinensis, Staphylococcus, Escherichia coli and Enterobacter cloacae. The bacterial strain E. coli MB641 showed sensitivity to Polymyxin only, and was resistant to all other antibiotics used. Maximum biofilm forming ability 0.532 ± 0.06, 0.55 ± 0.01 and 0.557 ± 0.07 was observed in Pseudomonas aeruginosa MB663, Pseudomonas aeruginosa MB664 and Bacillus spp. MB647 respectively after 24 hours of incubation. EPS production of bacterial strains was assessed, the polysaccharides and protein content of EPS were found to be in the range of 11-32 µg/ml and 2-10 µg/ml, respectively. Fourier transform infrared spectroscopic analysis of EPS showed the presence of carbohydrates, proteins, alkyl halides, and nucleic acids. X-ray diffraction analysis revealed crystalline structure of EPS extracted from biofilm forming bacteria. These findings suggest a high prevalence of antibiotic-resistant bacteria in orthopaedic implant-associated surgeries, highlighting the urgent need for ongoing monitoring and microorganism testing in infected implants.

Recent Advances in Psychopharmacology: From Bench to Bedside Novel Trends in Schizophrenia.

Research in the field of psychopharmacology is ongoing to develop novel compounds which can revolutionize the treatment of psychiatric disorders. The concept of bench-to-bedside is a tedious process, transforming the initial research performed in the laboratories into novel treatment options. Schizophrenia (SCZ) is a chronic psychiatric illness with significant morbidity and mortality. SCZ not only presents with psychotic symptoms including hallucinations and delusions but also with negative and cognitive symptoms. The negative symptoms include the diminished ability to express emotions, loss of pleasure, and motivation with minimal social interactions. Conventional antipsychotics primarily target positive symptoms with minimal therapeutic benefits for negative and cognitive symptoms along with metabolic side effects. Researchers have explored novel targets to develop new compounds to overcome the above limitations. The glutamatergic system has provided new hope in treating schizophrenia by targeting negative and cognitive symptoms. Other receptor modulators, including serotonergic, phosphodiesterase, trans-amine-associated receptors, etc., are novel targets for developing new compounds. Future research is required in this field to explore novel compounds and establish their efficacy and safety for the treatment of schizophrenia. Last but not least, pharmacogenomics has effectively utilized genetic information to develop novel compounds by minimizing the risk of failure of the clinical trials and enhancing efficacy and safety.

Gender bias in antidepressant direct-to-consumer pharmaceutical advertising.

BACKGROUND: Direct to consumer pharmaceutical advertising (DTCPA) may have significant impacts on public perception of diseases and treatments. Our objective was to examine whether DTCPA for antidepressants disproportionately portray and hence target women in the United States. METHODS: DTCPA for branded medications for depression, psoriasis and diabetes were analyzed to determine the gender of the main "patient" portrayed, as well as the content of the disease depiction. RESULTS: DTCPA for antidepressants included only women in 82% of ads, only men in 10.1% of ads, and both genders in 7.8% of ads. There were significantly higher representations of women versus men in DTCPA for antidepressants (82%) compared to either psoriasis (50.4%) or diabetes (37.6%) medications. These differences remained statistically significant even after adjusting for gender disparities in disease prevalence. CONCLUSIONS: Antidepressant DTCPA in the United States disproportionately target women. There are potential adverse consequences for both women and men resulting from unequal representations in DTCPA for antidepressant medications.

A Qualitative Inquiry of Parents' Observations of Their Children's Mental Health Needs During the COVID-19 Pandemic.

Given that children and adolescents are at critical periods of development, they may be particularly vulnerable to the effects of the COVID-19 pandemic. Using a descriptive phenomenological approach, 71 parents' observations of their child's mental health difficulties were explored. Parents sought out treatment because their children were experiencing significant distress. Data used were transcribed from baseline questionnaires and therapy summaries. Data analysis revealed three themes: emotion regulation difficulties, hypervigilance, and despair. The search for strategies and tailored interventions to help mitigate the potential harmful and long-term mental health impacts of the pandemic should be at the forefront of research and clinical practice.

Primary Outcomes for Adults Receiving the Unified Protocol after Hurricane Harvey in an Integrated Healthcare Setting.

The Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) has demonstrated efficacy for treating anxiety and depression. However, there are limited effectiveness data when conducted in real-world settings with diverse populations, including those with trauma. We evaluated treatment outcomes in a naturalistic, community setting among 279 adults who received UP following Hurricane Harvey. We examined change in overall clinical severity, depression and anxiety symptoms, functional impairment, and baseline outcome predictors (i.e., demographic characteristics, impact from Hurricane Harvey, co-occurrence of depression and anxiety symptoms). Global clinical severity, depression and anxiety symptoms, and functional impairment decreased by end-of-treatment. Participants experienced global symptom improvement to a lesser degree than demonstrated in efficacy trials. Participants who experienced greater storm impact reported larger reductions in anxiety symptoms than those less impacted by Harvey. Further studies evaluating the effectiveness of the UP post-disaster and with diverse samples are needed.

Brief, parent-led, transdiagnostic cognitive-behavioral teletherapy for youth with emotional problems related to the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has led to increased stress, anxiety, and depression in children. A six-session, parent-led, transdiagnostic, cognitive-behavioral teletherapy program was adapted from an established protocol to help youth aged between 5 and 13 years manage emotional problems during the pandemic. METHODS: One-hundred twenty-nine parents of youth struggling with emotional problems during the COVID-19 pandemic participated in the program. Parents reported on their children's psychosocial functioning before and after treatment using validated assessments. They also reported on treatment satisfaction. Clinician-rated global improvement was assessed at each session to determine clinically significant treatment response. RESULTS: Significant improvements in parent proxy-reported anxiety (d = 0.56), depression (d = 0.69), stress (d = 0.61), anger (d = 0.69), family relationships (d = 0.32), and COVID-19-related distress (d = 1.08) were found, with 62% of participants who completed the program being classified as treatment responders. Parents reported high levels of satisfaction with the program. LIMITATIONS: This study was limited by use of primarily parent-report assessments and a lack of a control group. CONCLUSIONS: Brief, parent-led, transdiagnostic cognitive-behavioral teletherapy appeared to be an effective way to help youth cope with the pandemic and may be a scalable framework in response to large-scale mental health crises.

Behavioral and Cognitive Response to Selective Serotonin Reuptake Inhibitors in Frontotemporal Lobar Degeneration: A Systematic Review and Meta-analysis.

OBJECTIVE: This article systematically reviews current literature on the efficacy and efficiency of selective serotonin reuptake inhibitors (SSRIs) in the treatment of patients with frontotemporal lobar degeneration (FTLD), with a particular focus on behavior and cognitive functions. METHODS: A search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using CENTRAL, MEDLINE, and Cochrane Library databases. Eleven randomized controlled trials and open-label studies looking at the effects of SSRIs on FTLD patients were included. A random-effects meta-analysis was performed, consisting of 3 randomized and controlled studies that used the neuropsychiatric inventory to assess SSRI intervention. RESULTS: The meta-analysis shows a combined mean reduction of 10.17 points (95% confidence interval, 18.14-2.19; P = 0.01) on the neuropsychiatric inventory with SSRI treatment in FTLD patients. The I2 calculated for this study was 62% (P = 0.07), which represents moderate heterogeneity among the studies. The Egger regression test (P = 0.526) did not show a publication bias. Sensitivity analysis showed no significant change. CONCLUSIONS: The current meta-analysis supports SSRIs as an intervention for management of behavioral symptoms of FTLD. Marked improvements were seen in disinhibition, irritability, aggression, and aberrant motor activity across studies. However, apathy/loss of empathy did not show similarly promising results. A deteriorative effect on cognition was seen associated with SSRI use.

Phenotypic detection of extended-spectrum beta-lactamase in multidrug-resistant acinetobacter baumannii isolated in Fauji Foundation Hospital Rawalpindi.

OBJECTIVE: To evaluate the phenotypic detection of extended-spectrum betalactamase in multidrug-resistant acinetobacter baumannii. METHODS: The cross-sectional study was conducted at the Department of Microbiology, Fauji Foundation Hospital, Rawalpindi, Pakistan, from August 2018 to April 2019, after the ethical approval from the Institutional Review Committee. Consecutive Non- probability sampling technique was used, and comprised clinical specimens, including pus, blood, sputum, urine, tracheal tubes and canula double lumen, which were processed using standard protocols. Colonies of acinetobacter baumannii were identified by gram staining and Analytical Profile Index-20E kit. Combination disc method was used for the identification of extended-spectrum beta-lactamse. Clinical and Laboratory Standards Institute guidelines were used for antimicrobial susceptibility. Data was analysed using SPSS 22 and Sample size was calculated by using earlier study with 5 % margin of error and 95 % confidence level. RESULTS: Of the 78 isolates, 58(74.4%) related to females and 20(25.6%) to males. There was no extended-spectrum beta-lactamse producer. Imipenem, meropenem, cefotaxime, ampicillin and ceftazidime showed 100% resistance, while colistin and polymyxin B were sensitive to all strains. The incidence rate was high in samples isolated from tracheal tubes 47(60.3%), followed by pus 21(26.9%). Age was not found to be a significant factor (p>0.05). CONCLUSIONS: Acinetobacter baumannii showed a high resistance to multiple drugs and was not confined to any specific age group. Colistin and polymyxin B were found to be better choices.

Birth Seasonality of Schizophrenia and Bipolar Disorder? A Review of Inpatient Records.

BACKGROUND: Numerous studies on seasonality of birth for mood disorders and schizophrenia have been published but findings are inconsistent 1. We aim to test the hypothesis of lack of seasonal birth differences in hospitalized Bipolar Disorder and Schizophrenia patients. METHODS: 15969 inpatient records in UTHealth Harris County Psychiatric Center between 2012-2014 were enrolled (HSC-MS-14-0274). Patients birth months that were diagnosed as Schizophrenia (n=4178) and Bipolar Disorder (n=5303) according to the DSM IV Criteria were tabulated including admitting diagnosis. Texas Birth statistics between 1903-1997 were obtained as control group (n= 17096471). RESULTS: There was no significant difference for winter births between schizophrenia patients and control group (P=0.738) and there was no significant difference for winter births between bipolar patients and control group either (P= 0.862). Mann Kendall Trend Analysis showed no significant trends of birth months for schizophrenia, bipolar and control groups. LIMITATIONS: The study limitations include being a retrospective study, inability to control for environmental factors, and recruiting from a single location. CONCLUSIONS: Our large sample showed no association between birth season or months with schizophrenia or bipolar disorder. Severe schizophrenia that requires admission may not be related with birth seasonality.

In vitro efficacy of Daptomycin against clinical isolates of Methicillin-resistant Staphylococcus aureus (MRSA).

This descriptive cross-sectional study was performed in the Department of Microbiology, Fauji Foundation Hospital, Rawalpindi, from March 2019 to September 2019 to determine the in vitro efficacy of Daptomycin against clinical isolates of Methicillin-Resistant Staphylococcus aureus (MRSA). Consecutive non-probability sampling technique was used and a total number of 270 patients' Pan Cultures having MRSA growth on Cefoxatin Disc with size less than 22 mm zone size were included in the study. Cultures were inoculated on MacConkey, Chocolate and Blood agar and then incubated for 24 hours at 37 degree Celsius. After incubation, Coagulase test, Catalase test and Gram staining technique were used for further identification. Minimum Inhibitory Concentration (MIC) of the isolates for Daptomycin was obtained by using E strips (Oxoid UK) according to Clinical & Laboratory Standards Institute (CLSI) guidelines. The mean age of the patients was 46.73±12.22 years, and the study included 147 (54.44%) males and 123 (45.56%) females. Regarding the type of specimen, there were 154 (57.04%) pus specimens, 54 (20.00%) blood specimens, 27 (10.00%) fluid specimens, 18 (6.67%) urine specimens, 10 (3.70%) high vaginal swabs (HVS) specimens and 7 (2.59%) sputum specimens. Daptomycin was effective in 264 (97.78%) patients with MIC range from .015 to 1 µg/ml on E strip.

Risk Factors for Acute Brucellosis in Patients on the Day of Admission at Selected Hospitals of Abbottabad, Pakistan.

Brucellosis is a neglected zoonotic disease of ruminants. It causes severe health problems in humans and significant economic loss. Only a limited number of studies have been conducted in Pakistan to determine the prevalence of human brucellosis and related risk factors. The objectives of the current cross-sectional study were to determine the prevalence of anti-Brucella antibodies in sera collected from symptomatic patients at three hospitals of Abbottabad using a commercial slide agglutination test (SAT) and to determine risk factors for brucellosis for these patients. Five hundred blood samples were collected. A questionnaire was filled in for each patient to obtain information on age, gender, living area, brucellosis associated symptoms, associated risk factors, pregnancy and abortion history. A total of 13.6% (n = 68) patients were found to be SAT positive and in 83.3% (n = 57) of these samples Brucella DNA was detected by genus specific RT-PCR for BCSP-31 gene. Statistical analysis was performed to determine odd ratios, risk ratios, 95% confidence intervals, and p-values. The prevalence of brucellosis by SAT was reported to be higher in women (14.6%, n = 44) than in men (12.1%, n = 24). The age group 25-50 years was found to be at higher risk for brucellosis (14.5%, n = 50) "animal contact" was reported as the main risk factor followed by "consumption of raw animal products." Out of 131 pregnant women and 21 patients had abortion, the seropositivity of Brucellosis was 9.9% and 23.8%, respectively. The present study reports a striking prevalence of brucellosis among patients including pregnant women at three hospitals of Abbottabad. These findings may foster strategies for controlling human brucellosis at household level, raising of awareness about brucellosis in hospital and family doctors, and finally in setting up an eradication program in the dairy industry.

Antimicrobial susceptibility pattern of Methicillin-resistant Staphylococcus Aureus isolates in Fauji Foundation Hospital Rawalpindi.

The current study was conducted in the Department of Microbiology, Fauji Foundation Hospital, Rawalpindi, from July 2018 to January 2019. The main purpose of the study was to evaluate Methicillin-resistant Staphylococcus aureus antimicrobial susceptibility pattern. Clinical samples were collected and cultured according to Clinical and Laboratory Standards Institute (CLSI) guidelines. A total of 90(30%) samples were found to be methicillin-resistant out of 300 samples of Staphylococcus aureus. Major isolates were 42 (46.67%) from pus and 22 (24.44%) from tracheal tubes. The incidence ratio of Methicillin-resistant Staphylococcus aureus was high in the samples isolated from 69 (76.67%) females compared to those of 21 (23.33%) males. Patients were more in the age group of 41 to 60 years. Vancomycin 90 (100%) was sensitive to all strains followed by Chloramphenicol 66 (73.33%) and Doxycycline 52 (57.78%). Imipenem, Meropenem andAugmentin showed resistance to all strains.

Tocilizumab for severe COVID-19 pneumonia: Case series of 5 Australian patients.

AIM: To describe the first Australian cases of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV2) disease (COVID-19) pneumonia treated with the interleukin-6 receptor antagonist tocilizumab. METHODS: Retrospective, open-label, real-world, uncontrolled, single-arm case series conducted in 2 tertiary hospitals in NSW, Australia and 1 tertiary hospital in Victoria, Australia. Five adult male patients aged between 46 and 74 years with type 1 respiratory failure due to COVID-19 pneumonia requiring intensive care unit (ICU) admission and biochemical evidence of systemic hyperinflammation (C-reactive protein greater than 100 mg/L; ferritin greater than 700 µg/L) were administered variable-dose tocilizumab. RESULTS: At between 13 and 26 days follow-up, all patients are alive and have been discharged from ICU. Two patients have been discharged home. Two patients avoided endotracheal intubation. Oxygen therapy has been ceased in three patients. Four adverse events potentially associated with tocilizumab therapy occurred in three patients: ventilator-associated pneumonia, bacteremia associated with central venous catheterization, myositis and hepatitis. All patients received broad-spectrum antibiotics, 4 received corticosteroids and 2 received both lopinavir/ritonavir and hydroxychloroquine. The time from first tocilizumab administration to improvement in ventilation, defined as a 25% reduction in fraction of inspired oxygen required to maintain peripheral oxygen saturation greater than 92%, ranged from 7 hours to 4.6 days. CONCLUSIONS: Tocilizumab use was associated with favorable clinical outcome in our patients. We recommend tocilizumab be included in randomized controlled trials of treatment for patients with severe COVID-19 pneumonia, and be considered for compassionate use in such patients pending the results of these trials.

Tracking and Predicting Depressive Symptoms of Adolescents Using Smartphone-Based Self-Reports, Parental Evaluations, and Passive Phone Sensor Data: Development and Usability Study.

BACKGROUND: Depression carries significant financial, medical, and emotional burden on modern society. Various proof-of-concept studies have highlighted how apps can link dynamic mental health status changes to fluctuations in smartphone usage in adult patients with major depressive disorder (MDD). However, the use of such apps to monitor adolescents remains a challenge. OBJECTIVE: This study aimed to investigate whether smartphone apps are useful in evaluating and monitoring depression symptoms in a clinically depressed adolescent population compared with the following gold-standard clinical psychometric instruments: Patient Health Questionnaire (PHQ-9), Hamilton Rating Scale for Depression (HAM-D), and Hamilton Anxiety Rating Scale (HAM-A). METHODS: We recruited 13 families with adolescent patients diagnosed with MDD with or without comorbid anxiety disorder. Over an 8-week period, daily self-reported moods and smartphone sensor data were collected by using the Smartphone- and OnLine usage-based eValuation for Depression (SOLVD) app. The evaluations from teens' parents were also collected. Baseline depression and anxiety symptoms were measured biweekly using PHQ-9, HAM-D, and HAM-A. RESULTS: We observed a significant correlation between the self-evaluated mood averaged over a 2-week period and the biweekly psychometric scores from PHQ-9, HAM-D, and HAM-A (0.45≤|r|≤0.63; P=.009, P=.01, and P=.003, respectively). The daily steps taken, SMS frequency, and average call duration were also highly correlated with clinical scores (0.44≤|r|≤0.72; all P<.05). By combining self-evaluations and smartphone sensor data of the teens, we could predict the PHQ-9 score with an accuracy of 88% (23.77/27). When adding the evaluations from the teens' parents, the prediction accuracy was further increased to 90% (24.35/27). CONCLUSIONS: Smartphone apps such as SOLVD represent a useful way to monitor depressive symptoms in clinically depressed adolescents, and these apps correlate well with current gold-standard psychometric instruments. This is a first study of its kind that was conducted on the adolescent population, and it included inputs from both teens and their parents as observers. The results are preliminary because of the small sample size, and we plan to expand the study to a larger population.
