ABSTRACT The patrol report is an important source of data concerning the history of colonialism in PNG. However, the patrol report as a specific set of documents with their own history has not itself been subject to analysis. The textual analysis outlined in this article is one approach to developing such a history. The article highlights the importance of official instructions on how a patrol report should be written and circulated within the bureaucracy. There were persistent attempts to regulate and reduce the flow of political and social issues into the centre of the state. These attempts were difficult to stabilize as they involved both the devaluation and revaluation of different types of knowledge found in patrol reports from the late 1950s to the early 1970s. What emerges from this analysis is a history that explores bureaucratic attempts to define and organize the way knowledge is reported and circulated rather than a history based on the content of those reports.

SARS-CoV-2 is a new, widespread virus pandemic that started in late 2019.It targets the respiratory system, especially the lungs and airways, through the spread of infected water droplets being inhaled through person-to-person transmission.Current treatments include oral antiviral pills like Paxlovid and mRNA vaccines, but these treatments have limitations in not reducing the occurrence of a common side effect of COVID-19.In this paper, we study the correlation of how SARS-CoV-2 (COVID-19) in intubated patients on ventilators can develop subglottic stenosis (SGS) during such treatments.When SARS-CoV-2 patients are treated with these devices, their tubes can injure and possibly scar the airway epithelium, resulting in excessive scar tissue growth that blocks the airway, which is SGS.SGS arises when an injury in the airway stimulates rapid scar tissue growth to the point where the airway becomes too narrow and obstructed for breathing.It can also lead to the entire airway collapsing in severe cases.Even then, many current treatments for SGS, such as laryngotracheal reconstruction (LTR) and partial cricotracheal resection (CTR) surgeries, make the condition of the patients worse, especially with long-COVID patients with comorbidities potentially having a collapsed trachea.Thus, it is essential to find novel treatments to lower the risk of SGS in patients with such severe cases of COVID-19.Therefore, in this work, we discuss novel therapies to treat SGS cases that have been occurring from incidences of COVID-19 as a way to improve patient outcomes and save lives.

Prosthetic valvular infolding during transcatheter aortic valve implantation (TAVI) is an under-recognized yet significant complication that can occur. Here, we describe the case of a 61-year-old male with a history of heart failure with reduced ejection fraction (HFrEF) and low-flow, low-gradient severe aortic valve stenosis of a bicuspid aortic valve who presented to undergo TAVI. During the procedure, repositioning of the valve resulted in prosthetic valvular infolding and resultant severe aortic regurgitation (AR), culminating in cardiac arrest. Swift balloon valvuloplasty corrected the valve geometry and eliminated any AR, allowing hemodynamic recovery and completion of the procedure. Our case and review highlight methods, both angiographic and echocardiographic, to recognize prosthetic valvular infolding the moment it presents, as well as strategies to correct the infolding with minimal detriment to the patient.

TPS9602 Background: Fianlimab (anti-lymphocyte activation gene 3 [LAG-3]) and cemiplimab (anti- programmed cell death-1 [PD-1]) are both high-affinity, fully human, IgG4 monoclonal antibodies (Abs). Concurrent blockade of anti-LAG-3 and anti-PD-1 has shown enhanced efficacy (increase in progression free survival [PFS]) in advanced melanoma (Mel). We previously presented data from a phase 1 study showing a 63.8% objective response rate (ORR) across two separate cohorts of advanced PD-(L)1 naïve metastatic Mel patients (pts) treated with fianlimab plus cemiplimab with an acceptable risk-benefit profile. Methods: This is a randomized, double-blind, phase 3 study to evaluate fianlimab plus cemiplimab compared to pembrolizumab in pts with previously untreated unresectable locally advanced or metastatic Mel (NCT05352672). This study will be conducted globally, at approximately 200 sites. Key inclusion criteria are: (1) ≥12 years of age; (2) histologically confirmed unresectable Stage III and Stage IV (metastatic) Mel (3) no prior systemic therapy for advanced unresectable disease, prior (neo)adjuvant therapies are allowed with treatment/disease-free interval of 6 months; (4) measurable disease per Response Evaluation Criteria in Solid Tumors version 1.1; (5) valid LAG-3 results; (6) Eastern Cooperative Oncology Group performance status (PS) of 0 or 1 (for adult pts), Karnofsky PS ≥70 (pts ≥16 years) or Lansky PS ≥70 (pts < 16 years); and (7) anticipated life expectancy of at least 3 months. There are 4 arms to the study: (1) Arm A: fianlimab (1600 mg) + cemiplimab (350 mg) every 3 weeks (Q3W), intravenously (IV); (2) Arm A1: fianlimab (400 mg) + cemiplimab (350 mg) Q3W, IV; (3) Arm B: pembrolizumab (200 mg Q3W, IV) + saline/dextrose placebo (placebo); (4) Arm C: cemiplimab (350 mg Q3W, IV) + placebo. The trial is expected to enroll approximately 1590 pts. The primary endpoint is progression-free survival. The key secondary endpoints are overall survival and objective response rate. The additional secondary endpoints include disease control rate, duration of response, safety, pharmacokinetics of cemiplimab and fianlimab, and immunogenicity (incidence and titer of anti-drug Abs and neutralizing Abs). The study is currently open for enrollment. Clinical trial information: NCT05352672 .

Social determinants of health, including neighborhood context, may be a key driver of severe maternal morbidity and its related racial and ethnic inequities; however, investigations remain limited. This study aimed to examine the associations between neighborhood socioeconomic characteristics and severe maternal morbidity, as well as whether the associations between neighborhood socioeconomic characteristics and severe maternal morbidity were modified by race and ethnicity. This study leveraged a California statewide data resource on all hospital births at ≥20 weeks of gestation (1997-2018). Severe maternal morbidity was defined as having at least 1 of 21 diagnoses and procedures (eg, blood transfusion or hysterectomy) as outlined by the Centers for Disease Control and Prevention. Neighborhoods were defined as residential census tracts (n=8022; an average of 1295 births per neighborhood), and the neighborhood deprivation index was a summary measure of 8 census indicators (eg, percentage of poverty, unemployment, and public assistance). Mixed-effects logistic regression models (individuals nested within neighborhoods) were used to compare odds of severe maternal morbidity across quartiles (quartile 1 [the least deprived] to quartile 4 [the most deprived]) of the neighborhood deprivation index before and after adjustments for maternal sociodemographic and pregnancy-related factors and comorbidities. Moreover, cross-product terms were created to determine whether associations were modified by race and ethnicity. Of 10,384,976 births, the prevalence of severe maternal morbidity was 1.2% (N=120,487). In fully adjusted mixed-effects models, the odds of severe maternal morbidity increased with increasing neighborhood deprivation index (odds ratios: quartile 1, reference; quartile 4, 1.23 [95% confidence interval, 1.20-1.26]; quartile 3, 1.13 [95% confidence interval, 1.10-1.16]; quartile 2, 1.06 [95% confidence interval, 1.03-1.08]). The associations were modified by race and ethnicity such that associations (quartile 4 vs quartile 1) were the strongest among individuals in the "other" racial and ethnic category (1.39; 95% confidence interval, 1.03-1.86) and the weakest among Black individuals (1.07; 95% confidence interval, 0.98-1.16). Study findings suggest that neighborhood deprivation contributes to an increased risk of severe maternal morbidity. Future research should examine which aspects of neighborhood environments matter most across racial and ethnic groups.
