RESUMO

INTRODUCTION: Same-day surgical case cancellation consumes resources, disrupts patient care, and has a global prevalence of 18%. A retrospective analysis found that 44% of scheduled elective surgeries were canceled at a public tertiary hospital in Lilongwe, Malawi. To better characterize these cancellations, this study defines a process map for surgical case completion and investigates hospital staff and patient perspectives on contributing factors and burdens of cancellation. METHODS: We conducted participatory process mapping and in-depth interviews with hospital staff (n = 23) and patients (n = 10) to detail perioperative processes and perspectives on cancellations. We used purposive sampling to recruit staff by hospital role and patients whose surgery had been canceled. Interviews were audio-recorded, translated, and transcribed for process mapping accuracy and thematic analysis using the constant comparative method and NVivo software. RESULTS: Staff delineated specific steps of the perioperative process, generating a process map that identifies inefficiencies and opportunities for intervention. Hospital staff described unavoidable causes of case cancellation, such as unreliable water supply and material shortages. Modifiable causes linked to wasted time and resources were also evident, such as chronic tardiness, communication barriers, and inadequate preoperative assessment. Thematic analysis of perceived impacts of cancellation revealed compromised provider-patient relationships, communication breakdown, and emotional distress. Staff and patients expressed frustration, embarrassment, fear, and demoralization when planned surgeries were canceled. CONCLUSIONS: We demonstrate the use of process mapping as a tool to identify implementation targets for reducing case cancellation rates. Hospital systems can adapt this approach to address surgical case cancellation in their specific setting.

RESUMO

Infected necrotizing pancreatitis is a challenging condition to treat because of the profound inflammatory response these patients undergo which can then be exacerbated by interventions. Treatment of this condition has evolved in timing of intervention as well as method of intervention and includes less invasive options for treatment such as percutaneous drainage and endoscopic drainage, in addition to less invasive endoscopic and video-assisted or laparoscopic debridements. The precise optimal treatment strategy for these patients is an ongoing topic of discussion and may be different for each patient as this is a heterogenous condition.

RESUMO

An asymptomatic 73-year-old woman was found to have a submucosal mass in the descending colon on routine colonoscopy. A CT scan revealed a 31 × 28 × 31 mm lesion in the same location. Previous biopsy proved to be nondiagnostic, and the patient underwent a laparoscopic descending colon resection. Histologic evaluation of the tumor revealed a low grade spindle cell neoplasm with strong, diffuse positivity for S-100 protein by immunohistochemistry, leading to the diagnosis of schwannoma. A review of the literature revealed intestinal schwannoma to be a rare disease entity, with only about 50 cases previously reported.

RESUMO

BACKGROUND: The impact of surgical conditions on global health, particularly on vulnerable populations, is gaining recognition. However, only 3.5% of the 234.2 million cases per year of major surgery are performed in countries where the world's poorest third reside, such as the Democratic Republic of the Congo (DRC). METHODS: Data on the availability of anesthesia and surgical services were gathered from 12 DRC district hospitals using the World Health Organization's (WHO's) Emergency and Essential Surgical Care Situation Analysis Tool. We complemented these data with an analysis of the costs of surgical services in a Congolese norms-based district hospital as well as in 2 of the 12 hospitals in which we conducted the situational analysis (Demba and Kabare District Hospitals). For the cost analysis, we used WHO's integrated Healthcare Technology Package tool. RESULTS: Of the 32 surgical interventions surveyed, only 2 of the 12 hospitals provided all essential services. The deficits in procedures varied from no deficits to 17 services that could not be provided, with an average of 7 essential procedures unavailable. Many of the hospitals did not have basic infrastructure such as running water and electricity; 9 of 12 had no or interrupted water and 7 of 12 had no or interrupted electricity. On average, 21% of lifesaving surgical interventions were absent from the facilities, compared with the model normative hospital. According to the normative hospital, all surgical services would cost US$2.17 per inhabitant per year, representing 33.3% of the total patient caseload but only 18.3% of the total district hospital operating budget. At Demba Hospital, the operating budget required for surgical interventions was US$0.08 per inhabitant per year, and at Kabare Hospital, US$0.69 per inhabitant per year. CONCLUSION: A significant portion of the health problems addressed at Congolese district hospitals is surgical in nature, but there is a current inability to meet this surgical need. The deficient services and substandard capacity in the surveyed district hospitals are systemic in nature, representing infrastructure, supply, equipment, and human resource constraints. Yet surgical services are affordable and represent a minor portion of the total operating budget. Greater emphasis should be made to appropriately fund district hospitals to meet the need for lifesaving surgical services.

RESUMO

HIV infection is characterized by CD4(+) T cell depletion and progressive immune dysfunction; particularly impacted are HIV-specific T cell responses. An important component of immune-mediated control of HIV replication, killing of infected cells, appears to be impaired, in part due to poor cytolytic activity of HIV-specific cytotoxic T cells (CTL). In vitro, several functions of HIV-specific T cells, such as cytokine production, can be enhanced by the depletion of the immunosuppressive CD25(+) FoxP3(+) CD4(+) regulatory (Treg) cell subset. However, the effect of CD25(+) Treg cells on virus-specific cytolytic activity in the context of HIV or any human viral infection has not been investigated. The present study demonstrates that CD25(+) Treg cells isolated from the peripheral blood of HIV-infected subjects significantly suppress HIV Gag-specific cytolytic activity in vitro. In addition, CD25(+) Treg cells suppress effector function (coexpression of TNF-alpha and IFN-gamma) of HIV-specific CD8(+) T cells that proliferate in response to HIV antigen. Finally, the secretion of HIV-inhibitory CC-chemokines by HIV-specific and nonspecific CD8(+) T cells is significantly reduced in the presence of CD25(+) Treg cells. These data suggest that CD25(+) Treg-mediated suppression of the antiviral activity of HIV-specific CD8(+) T cells could impact the ability of HIV-infected individuals to control HIV replication in vivo.
