Strong growth in the demand for tea requires further increases in the productivity of plantations. Declining or stagnant yields are commonly observed in older plantations. Possible controlling factors for yield decline are reviewed including ageing of plants, chronic disease and sub-optimal soil conditions such as excess soil acidity and low soil organic matter. Management options for addressing these factors are evaluated, including replanting. A systematic approach to decision-making about replanting is presented. Practice for replanting is reviewed and it is concluded that evidence to support a general case for replanting is limited, unless based on the introduction of more productive clones and/or better plant spacing.

Redo mitral valve replacement with annular reconstruction of left atrial dissection following mitral valve replacement for infective endocarditis: a case report.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.

Backgrounds: Poverty is a complex and multifaceted global public health issue, particularly prevalent in Ethiopia, including the East Gojjam Zone. Previous studies on poverty have largely relied on unidimensional measures, providing limited evidence on multidimensional poverty (MP). Therefore, this study tried to assess the prevalence and identify the associated factors of MP among rural households in selected woredas of East Gojjam Zone, Northern Ethiopia.

Background: Transcatheter aortic valve replacement (TAVR) harbors the risk of periprocedural complications that require emergent cardiac surgery, or "surgical bailout." Surgical bailout intends to be lifesaving but is associated with high mortality. This has given rise to discussion on the necessity of surgical backup during TAVR.

When asked why nearly all doctors refer their breech cases to surgery, despite non-surgical breech birth being permitted throughout the United States, an obstetrician will likely cite the Term Breech Trial (TBT). This study, conducted in 2000, decisively concluded that planned cesarean delivery is safer than vaginal breech delivery. However, a review of the literature suggests that the decline of vaginal breech deliveries was a long time in the making.
